how to pilot a hot air balloon
Flying Without a Rudder
An essay on how to pilot a hot air balloon — and on the peculiar discipline of navigating an aircraft that cannot be aimed.
The first thing to understand about piloting a hot air balloon is that the verb "to pilot" does most of its work sideways. A fixed-wing pilot flies an airplane; a helicopter pilot flies a helicopter; in each case the verb implies a machine that is doing what the pilot tells it to do. A balloon pilot flies a balloon in the way a sailor sails a current. The aircraft has exactly one control axis — up and down — and every horizontal decision the pilot makes must be extracted, indirectly, from that single degree of freedom and from whatever the atmosphere happens to be doing that morning. Everything else in the craft is in service to that one trick.
This essay is a walk through that trick, from the preflight weather brief to the moment the basket settles into tall grass. It is not a substitute for the Federal Aviation Administration's Balloon Flying Handbook (FAA-H-8083-11B, December 2024), which runs to more than 200 pages and is the official reference for every U.S. balloon pilot certification. It is, rather, an engineer's attempt to explain what the handbook describes — what the craft actually is, what the pilot is actually doing, and why the pilot's decision loop is so unlike the decision loops of other aircraft.
The Machine
A hot air balloon has three parts: an envelope, a burner system, and a basket. The envelope is a tall teardrop of lightweight nylon or polyester fabric, reinforced by sewn-in load tapes that form a load-bearing net over the soft skin. It is open at the bottom (the mouth or throat) and has a controllable vent at the top (the parachute valve or deflation port), held closed in flight by the pressure of the hot air inside and by a center line running down to the basket. The fabric nearest the burner — the skirt — is coated with a fire-resistant treatment because the flame column passes a few feet below it several dozen times an hour.
The burner is a propane-fueled heat gun, not a cooking stove. A typical modern ride balloon carries two or three burners in a single gimbaled frame above the basket, each capable of roughly 20 to 30 million British thermal units per hour at full output. Propane is stored as liquid under pressure in aluminum or stainless-steel tanks mounted inside the basket — usually two to four tanks of 10, 15, or 20 gallons each. A blast valve releases vaporized propane into the burner for a loud, efficient blue flame used for rapid heating; a whisper or liquid valve releases liquid propane directly to a secondary coil for a quieter, orange flame used over livestock, during night glows, or when the pilot is trying not to wake up a neighborhood.
The basket is woven wicker over a welded steel or aluminum frame. Wicker is not nostalgia; it is a carefully chosen engineering material. It has excellent energy absorption during hard landings, high strength-to-weight ratio, and a benign failure mode — it crushes progressively rather than shattering. Larger commercial baskets are divided into compartments by internal partitions, with the pilot standing in the center compartment and passengers in the outer compartments. Some commercial baskets — including many operated in Temecula — incorporate a hinged door, saving passengers from climbing over a four-and-a-half-foot sidewall on landing.
The whole assembly, fully fueled and with a pilot and ten passengers aboard, typically masses between 1,400 and 2,200 kilograms. To lift that mass, an envelope must contain on the order of 77,000 to 105,000 cubic feet of air (roughly 2,200 to 3,000 cubic meters) heated to 90 to 120 degrees Celsius. The buoyancy arithmetic is unforgiving and scales only by volume of the envelope — which is why ride balloons are so enormous compared to sport or private balloons.
The Weather Brief
A balloon flight begins the night before, at a computer. The pilot pulls surface and upper-air forecasts, airport terminal forecasts (TAFs) and area forecasts (FAs), winds-aloft products at successive altitudes (typically 3,000, 6,000, 9,000, and 12,000 feet), and any convective or precipitation outlooks. In mountainous terrain the pilot adds orographic and lee-wave products. In coastal zones — Temecula, for instance — the pilot adds the marine layer top forecast, because a 900-foot marine inversion sitting over an otherwise benign morning can trap a balloon in a wind shear layer that does not appear in any standard product.
The pilot is not looking for "good weather" in the abstract. The pilot is looking for a specific, narrow, local weather envelope: surface winds under roughly 5 to 10 miles per hour (operator- and experience-dependent), visibility better than one statute mile, cloud clearance sufficient for visual flight rules, no convective activity forecast within the flight window, no frontal passage, no thunderstorm within roughly 100 miles of the intended flight path, and — critically — a workable set of wind directions stacked at different altitudes. A balloon that launches under a westerly surface flow but finds a northerly above 1,500 feet and a westerly again above 3,000 feet has three useful steering options. A balloon that finds the same wind direction at every altitude has none, and in that case the pilot lands wherever the wind takes the craft and the next available landing site permits.
The Pibal
Thirty minutes before launch, the pilot releases a small helium-filled balloon from the launch field. This is the pibal, short for "pilot balloon" — a 10- to 14-inch toy balloon with a known ascent rate and a bright, easily tracked color. The pibal is the single most useful instrument in ballooning.
The pibal does three jobs at once. First, it confirms or refutes the morning's forecast by showing the pilot what the wind is actually doing, layer by layer, at the launch site. Second, its behavior in the first few hundred feet tells the pilot whether to launch at all: a pibal that tumbles along the ground, climbs and then dives, or lurches sideways from one direction to another is describing a wind shear that the balloon will experience too. Third, by timing its ascent against a stopwatch and tracking its bearing with a handheld compass or inclinometer, the pilot can build a rough steerage profile — a mental map of "if I need to go northeast, I climb to 1,800 feet; if I need to go east, I stay at 800 feet; if I need to go south, I descend to 300 feet."
Experienced pilots often release several pibals at 10- to 20-second intervals, with different helium fills to produce different ascent rates, so that the low-level wind structure can be read more finely. If the pibals say launch, the pilot launches. If they say do not launch, no amount of passenger disappointment overrides them. Canceled flights are the price of uncanceled flights ending safely.
Inflation and Launch
Inflation is a choreography. The envelope is laid out downwind of the basket on its side, mouth facing the basket. A large gasoline-powered fan forces ambient-temperature air into the envelope — a process called cold inflation — until the envelope is perhaps 70 percent inflated and lying on its side like a beached whale. The crew holds the mouth open by the load tapes at the top and bottom of the opening, called the crown and throat. The pilot then tips the burner frame horizontal, aims into the mouth, and begins burning — hot inflation.
Over three or four minutes the envelope rises, pivoting on its equator until it is fully upright above the basket. At this point the balloon is approximately neutrally buoyant: hot enough to stand up under its own load, not yet hot enough to lift the basket off the ground. The pilot tethers the basket to a chase vehicle with a quick-release line, runs through the final checklist (fuel lines pressurized, pilot light lit, blast valves functional, vent line clear, passenger briefing complete, camera crew and crowd cleared of the burner exhaust path), and loads passengers.
Launch itself is almost anticlimactic. One sustained burn takes the balloon from neutral to positively buoyant; the quick-release is pulled; the basket lifts off the ground at one or two feet per second. There is no roar of engines because there is no engine. There is only the intermittent hiss-and-thunder of the burner and, between burns, a silence so complete that passengers can usually hear dogs barking a mile away.
The Central Problem of Navigation
Once airborne, the pilot faces the problem that defines ballooning: the aircraft cannot be aimed. It is not underpowered. It is unpowered. It moves exactly as fast as the air around it is moving, in exactly the direction the air around it is moving, and any attempt to think otherwise will shortly be corrected by the landscape.
— FAA Balloon Flying Handbook, Chapter 7
What the pilot can do — the only thing the pilot can do — is choose altitude. The atmosphere, conveniently, is not a uniform slab of moving air. It is a stack of layers, each moving at its own speed and in its own direction. The layers form because of friction with the ground (surface winds are slower and more aligned with pressure gradients than free-stream winds above the planetary boundary layer), because of the Coriolis effect (in the Northern Hemisphere, wind direction generally veers to the right with altitude, a phenomenon known as the Ekman spiral), because of thermal stratification (marine inversions, nocturnal radiation inversions, and frontal surfaces each cap distinct air masses), and because of terrain channeling (valley winds sort themselves into patterns determined by the geometry of the hills around them).
The pilot's job is to read this stack in real time and select the layer whose direction most closely matches the desired course — a technique variously called altitude tacking, wind-layer steering, or simply steerage. To "turn left," the pilot does not turn anything. The pilot climbs, or descends, until the balloon enters a layer whose wind vector has a leftward component relative to the current track, and drifts. Then, when the new track is established, the pilot holds that altitude for as long as the new direction is useful, and changes altitude again when it is not.
Reading the Invisible
Reading the wind stack from inside a balloon is a craft in itself. The pilot cannot see air. The pilot must infer direction and speed from the things air moves.
Above the balloon the pilot reads clouds — cumulus drift, cirrus streaks, any aircraft contrails. Below the balloon the pilot reads everything available: chimney smoke, dust kicked up by a tractor on a dirt road, the set of flags on a flagpole, the heeling angle of a sailboat on a lake, the bend of tall grass in a field, the sway of poplar or aspen leaves, the direction cattle are facing (they graze into the wind). In Temecula, pilots read the windsock at French Valley Airport when they can see it, and they read the laundry lines of the houses below them when they can't.
When the visible cues thin out, the pilot makes the wind visible. A spit over the side falls through the layers; the pilot watches its path and reads the turns. A squirt of shaving cream does the same job, trails for thousands of feet, and is more acceptable to passengers. Some pilots carry tissue paper or small confetti for the same purpose. These are not folk techniques pressed into duty by primitive technology; they are documented in the FAA handbook and are still the fastest way to sample the wind field immediately beneath the craft.
Above the craft, the pilot's options are more limited. A modern basket carries a variometer (a rate-of-climb indicator), an altimeter, a compass, a GPS receiver displaying ground track, and in some operations a satellite-data tablet showing winds-aloft updates in near-real time. None of these tell the pilot directly what the wind is doing at an altitude the balloon has not yet visited. For that, the pilot must climb and see, or descend and see, and make a decision based on the answer. The flight becomes an iterative sampling of the wind stack — climb 200 feet, see what the drift does, decide whether to stay or to keep climbing.
The Decision Loop
A balloon pilot's decision loop runs continuously from launch to landing, and it looks nothing like the checklist-driven flows of other aviation. The loop is closer to what a sailor does on a long tack, or what a chess player does in a middlegame: assess the field, identify the set of reachable states, choose the one with the best expected outcome, commit to it, and update as new information arrives. The FAA handbook borrows John Boyd's OODA framework — Observe, Orient, Decide, Act — and the fit is deliberate.
At every moment, the pilot is holding several concurrent questions in working memory. Where is the balloon now? What is the current altitude, heading, and drift speed? What is the fuel state — not in total tank volume, but in remaining flight minutes under the current burn rate and ambient temperature? Where are the reachable landing sites from the current altitude and drift? Which of those sites are preferred — open, away from power lines, away from livestock, on ground the pilot has permission to access, and within reach of the chase vehicle? Which are merely acceptable — adequate as a precautionary landing if the wind shifts? Which are unacceptable — schoolyards, dense residential blocks, freeways, agricultural fields with standing crops, power-line corridors, bodies of water?
The pilot is, in effect, running a continuously updated reachability map. The map shrinks as fuel burns down. It expands or contracts as the wind layers shift. It is constrained by airspace — a Class B ceiling, a Class D tower zone, a temporary flight restriction over a wildfire or a sporting event — that the pilot must not enter without clearance. And it is shaped by the simple fact that a balloon has momentum. If the pilot is at 2,000 feet and spots a problem on the ground, it takes a minute or more of venting — and a mile or so of horizontal drift — before the basket is near the surface.
The Delay Problem
That delay is the hardest single thing about piloting a balloon. The craft does not respond to control inputs the way airplanes do. Lighting the burner today does not make the balloon rise today; it makes the balloon rise in 20 to 40 seconds, depending on envelope size, outside air temperature, and how cool the air inside the envelope has become. Venting today does not make the balloon descend today; the air that remains inside is still hot, still buoyant, and the descent builds gradually over half a minute.
The FAA handbook's guidance on this is straightforward and, on first reading, counterintuitive: the rate of climb should not exceed the distance to the new altitude. If the pilot is 500 feet below the target altitude, the climb rate should not exceed 500 feet per minute. If the pilot is 300 feet below, the rate should not exceed 300 feet per minute. At 100 feet below, the rate should be down to about 100 feet per minute. This is not a speed limit imposed for comfort. It is a margin for the delay. A balloon climbing at 800 feet per minute through the last 300 feet of its target altitude will coast well past that altitude before the pilot can arrest it, and by then the pilot is in a different wind layer than the one intended, moving in a different direction than the one planned.
A good balloon pilot learns to anticipate outcomes roughly 30 seconds in the future and to fly toward the future rather than the present. An inexperienced pilot chases the present and spends the flight oscillating — over-burning, over-venting, over-burning, over-venting — and burns through fuel reserves without going anywhere useful.
Level Flight
Counterintuitively, level flight is harder than climbing or descending. A climbing balloon is in a dynamically stable regime — the pilot is adding heat faster than the envelope is losing it, and small errors are absorbed by the trend. A descending balloon is similarly stable — the pilot is adding heat slower than the envelope is losing it. Level flight requires the pilot to match the heat loss rate almost exactly, burn for burn, which means reading the variometer continuously and making small corrective burns of one to two seconds at intervals of 15 to 45 seconds.
The pilot's sense of timing in level flight becomes almost automatic with experience — a kind of trained proprioception. Commercial pilots with several thousand hours often describe it as knowing the "heartbeat" of a particular envelope. Different envelope sizes, different envelope ages, different ambient conditions, and different load states each have a slightly different rhythm, and the pilot learns to adjust without conscious thought.
Landing: The Hard Part
All balloon flights end with a landing, and nearly all balloon accidents happen during landing. The 2014 Johns Hopkins epidemiology of commercial balloon tour crashes (Ballard-Barash et al., based on NTSB data from 2000 through 2011) found that 81 percent of tour crashes occurred during landing, and 65 percent of those involved hard landings. The dominant injury mode — 56 percent of serious injuries — is lower-extremity fracture from an impact against the basket floor or a sidewall during an unexpected ground contact.
The FAA handbook describes landing as a two-phase problem: selecting the landing site, and flying the approach. Site selection begins roughly ten minutes before the intended touchdown, when the pilot descends to 500 to 800 feet above ground level and surveys the terrain ahead along the current drift track. A good landing site has four properties: it is open enough to accommodate the envelope as it falls on touchdown (roughly 100 feet by 100 feet for a ride-sized balloon); it is clear of obstacles on the upwind approach path (no tall trees, no power lines, no structures closer than a few balloon heights); it is on ground the pilot has either explicit permission or reasonable legal expectation to access; and it is reachable by the chase vehicle on a nearby road.
The approach itself is flown as a shallow descent along a path the pilot calls the glide slope, though the term is loose — the slope is whatever the combination of descent rate and ground speed produces. The pilot aims to touch down at the upwind edge of the chosen site, so that the basket has room to drag or bounce downwind before coming to rest. The final hundred feet are managed by small burns to arrest descent rate — the classic technique is to "fly the balloon into the ground" rather than letting it fall in. A basket dropping at more than about 500 feet per minute in the final seconds will hit hard enough to break ankles. A basket dropping at 100 feet per minute will settle like a car parking.
Before touchdown the pilot gives the final passenger briefing, which has not changed materially since the 1960s: face the direction of travel; knees bent; hold the interior handles; stay in the basket until told to get out; do not grab the outside of the basket. Passengers who reach for the ground as the basket tips on landing have been responsible for a significant fraction of broken wrists and separated shoulders in the accident record.
Precautionary and Emergency Landings
Every balloon pilot carries a continuously updated answer to the question "if I had to land right now, where would I put it?" A precautionary landing is one the pilot chooses to make before the situation forces it — fuel approaching reserves, winds turning toward unlandable terrain, a convective cell building in the distance, a passenger becoming ill. An emergency landing is one the pilot is compelled to make by an immediate problem: a burner failure, a fabric tear, a rapid weather change, a medical emergency aboard.
Precautionary landings are the mark of a good pilot. They look, from the outside, like something went wrong — a balloon dropping into a yard that was obviously not the planned landing site. From the inside, they are usually the opposite: a pilot who noticed that the planned landing site was becoming unreachable ten minutes before it would have mattered, and who landed short, in a smaller but adequate site, while options still existed. The Temecula landing of April 18, 2026, in which a Magical Adventure Balloon Rides pilot set a 13-passenger basket into a 10-foot grass strip in the Perrin family's backyard with no damage and no injuries, was a textbook precautionary landing — wind shift plus low fuel, identified early enough to find a workable site, executed with enough vertical precision to clear the fence, the house, and the trees. The company's owner described the pilot as having "exercised great judgment." The FAA would call it airmanship.
What the Pilot Is Really Doing
What does all of this add up to? What is the piloting of a balloon actually, finally, about?
It is about holding a probabilistic model of the atmosphere in working memory and updating that model continuously against sparse, noisy observations. It is about recognizing that the aircraft has exactly one control input and using that input to maximize the set of reachable futures. It is about working with delays — in the craft's response, in the pilot's own perception, in the weather's evolution — that would be disqualifying in any other flight discipline. It is about accepting that the destination is not a point but a set, and that the pilot's job is to keep that set non-empty until a good element of it is within reach.
It is, in the end, a navigation problem with the steering removed. The pilot cannot choose where to go. The pilot can only choose which of the places the wind is willing to take the craft is the best place to end up, and then spend the flight continuously winnowing that choice down to a single field, a single clearing, a single ten-foot strip of grass between a hill and a fence. The good pilot arrives there with fuel to spare, passengers uninjured, the basket upright, and the story later told as if nothing remarkable had happened.
It is an aviation discipline of great age — older than the airplane by 120 years — and it remains, in the literal sense, the oldest way humans know how to fly. It is also, perhaps uniquely among aviation disciplines, one in which the pilot's relationship to the air is one of collaboration rather than command. The wind does what it does. The pilot listens, adapts, and occasionally, with enough skill and enough luck, arrives exactly where the wind was going all along.
