One of the most common questions people ask before their first balloon flight is: "How does the pilot steer?" It is a perfectly reasonable question — after all, every other vehicle you have ever been in has some kind of steering mechanism. Cars have a wheel. Boats have a rudder. Aeroplanes have ailerons and a yoke. But look at a hot air balloon and you will see nothing of the sort. No wheel, no rudder, no ailerons, no engine, no propeller. Just a big fabric envelope, a wicker basket, and a flame.
So how on earth does the pilot control where it goes?
The answer is both deceptively simple and wonderfully clever: altitude is the steering mechanism. The pilot navigates by moving the balloon up or down to find wind layers blowing in the desired direction. It is a form of flight that has more in common with sailing than with aviation, and it requires a blend of meteorological knowledge, quick decision-making, and experience that few other flying disciplines demand.
The Fundamental Principle: Wind Layers
The atmosphere is not a single uniform mass of moving air. It is made up of layers, and at any given moment, the wind at 50 metres above the ground might be blowing in a completely different direction — and at a different speed — from the wind at 200 metres or 400 metres.
These differences arise from several factors: friction with the terrain slows and redirects wind at lower altitudes, thermal currents create localised wind patterns, and larger weather systems establish broader directional flows at higher levels. The result is that the atmosphere is effectively a stack of invisible rivers, each flowing in its own direction at its own pace.
A balloon pilot's job is to read these rivers and navigate between them. Want to head north-east? Climb to the altitude where the wind is blowing north-east. Need to slow down? Descend to a level where the wind is lighter. Want to change course? Move to a different altitude where the wind takes you in the new direction.
This is what makes ballooning so different from any other form of flight. You do not fight the wind — you use it. The pilot works with the atmosphere rather than against it, finding the right current and riding it like a leaf on a stream.
Pre-Flight Wind Reading
Long before the balloon is even unpacked from its bag, the pilot is gathering information about the wind.
Pi-Balls
One of the oldest and most reliable techniques is releasing a pi-ball — a small helium-filled pilot balloon about 30 centimetres in diameter. The pilot releases it from the proposed launch site and watches its trajectory through binoculars or simply with the naked eye.
The pi-ball reveals several critical pieces of information:
- Surface wind direction and speed — which way and how fast the balloon drifts at low level
- Wind shear — whether the wind changes direction or speed at different altitudes
- Stability — whether the pi-ball rises smoothly (stable air, good for flying) or bounces around (turbulent air, potentially unsuitable)
A single pi-ball can tell an experienced pilot more about the flying conditions than a dozen weather apps. The technique has been used since the earliest days of ballooning and remains indispensable.
Weather Briefings and Forecasts
Modern pilots also consult detailed meteorological data: surface analysis charts, upper wind forecasts, terminal aerodrome forecasts (TAFs), and satellite imagery. In Marrakech, our pilots review regional weather models specific to the Palmerie and the Atlas Mountain foothills, which have their own microclimate patterns that general forecasts sometimes miss.
The pre-flight briefing determines not just whether to fly, but where to launch from and what general trajectory to expect. If the winds aloft favour a south-to-north track, the pilot will choose a launch site that makes the most of this direction, aiming for terrain that offers the best views and safest landing options along the likely flight path.

How the Pilot Controls Altitude
Since altitude is the steering mechanism, the pilot needs precise control over how high the balloon flies. This is achieved through two simple but effective tools.
The Burner
The burner heats the air inside the envelope, making it less dense than the surrounding atmosphere. This generates buoyant lift and the balloon ascends. Short bursts of flame produce gentle climbs; longer burns produce more rapid ascents.
There is a delay between firing the burner and the balloon responding — typically 15 to 30 seconds. This is because it takes time for the heat to distribute through the enormous volume of air inside the envelope (2,800 cubic metres in a typical balloon). Skilled pilots learn to anticipate this lag, firing the burner before they need the lift rather than reacting to altitude changes after they occur.
The Parachute Valve
At the very top of the envelope sits the parachute valve — a circular panel of fabric that the pilot can open by pulling a cord. When opened, hot air escapes from the top of the envelope, cooler ambient air enters from the open bottom, the average air temperature inside decreases, density increases, and the balloon descends.
The pilot can open the valve by varying degrees to control the rate of descent. A brief pull releases a small amount of hot air for a gentle descent; a longer pull produces a more pronounced drop in altitude. Combined with the burner, this gives the pilot smooth, continuous control over altitude — and therefore over the balloon's direction of travel.
For a complete explanation of the mechanical systems, our guide on how hot air balloons work covers the burner, valve, and envelope in detail.
Turning Vents and Rotation
Some modern balloon envelopes are equipped with turning vents — small openings near the base of the envelope that can be opened asymmetrically to cause the balloon to rotate around its vertical axis. This does not change the direction of travel (that is still determined by the wind), but it allows the pilot to rotate the basket so that passengers can enjoy views in all directions during the flight.
Turning vents are particularly useful during the scenic portions of the flight. Rather than having one side of the basket facing a stunning view while the other side looks at featureless terrain, the pilot can slowly rotate the basket to give everyone a turn with the best vantage point.
The Common Misconception
Perhaps the most widespread misconception about ballooning is that balloons drift randomly — that the pilot simply goes up and waits to see where the wind takes them, with no input or control over the outcome.
This could not be further from the truth. While a balloon pilot does not have the precise directional control of an aeroplane pilot, they exercise a remarkable degree of influence over their flight path. Through careful pre-flight planning, constant observation of wind patterns during flight, and skilled use of the burner and valve, an experienced pilot can:
- Navigate towards a desired general area
- Avoid obstacles such as power lines, built-up areas, and restricted airspace
- Select appropriate landing sites
- Adjust speed by moving to faster or slower wind layers
- Extend or shorten the flight path as conditions require
It is a different kind of control from what you might expect — more like a sailor trimming sails to work with the wind than a driver turning a steering wheel — but it is genuine, skilled navigation nonetheless.
The Role of Experience
More than almost any other form of aviation, balloon piloting is a craft that rewards experience. The same stretch of sky can behave completely differently from one morning to the next, and the ability to read subtle signs — a wisp of smoke from a village chimney, the movement of grass on a hilltop, the shape of clouds forming at a particular altitude — is something that develops only through hundreds of hours of flying.
In Marrakech, our pilots have extensive experience flying over the Palmerie and the terrain between the city and the Atlas Mountains. They know the local wind patterns intimately: how the morning drainage flow comes down from the mountains, how the wind tends to back or veer as the sun rises, which altitudes typically offer which directions of travel over this particular landscape.
This local knowledge is enormously valuable. A pilot who has flown a thousand hours over the English countryside would still need time to learn the specific atmospheric character of Marrakech. Our pilots have that knowledge built up over years, and it translates directly into smoother, more scenic, and safer flights for passengers.
The Chase Crew
Because a balloon travels with the wind and typically does not return to its launch point, a ground-based chase crew is an essential part of every flight. The crew follows the balloon in a vehicle towing a trailer (for transporting the deflated balloon after landing) and stays in radio contact with the pilot throughout.
GPS Tracking
Modern balloon operations use GPS tracking to allow the chase crew to follow the balloon's exact position in real time. The pilot's GPS coordinates are transmitted to the crew, who can see the balloon's track on a map and position themselves near the expected landing area well before the balloon arrives.
Radio Communication
The pilot and chase crew maintain regular radio contact. The pilot relays altitude, speed, direction, and intentions. The chase crew reports on ground conditions at potential landing sites — whether a field is clear, whether there are power lines in the area, whether a road provides access for the trailer.
This coordination becomes particularly important during the landing phase, when the pilot needs to select a suitable site and the crew needs to be in position to assist passengers and secure the equipment.
Navigation Technology
While the fundamental skill of reading the wind remains unchanged since the Montgolfier brothers' first flights in 1783, modern balloon pilots benefit from technology that their predecessors could only dream of.
GPS and Flight Computers
Handheld GPS units show the pilot their exact position, altitude, ground speed, and track over the ground. Some pilots use tablet-based moving map displays that overlay the flight path on satellite imagery, making it easy to identify terrain features, potential landing sites, and obstacles.
Variometers
A variometer measures the rate of climb or descent in real time, displayed as metres per second or feet per minute. This allows the pilot to quantify exactly how the balloon is responding to burner inputs and valve operations, rather than relying purely on visual references.
Weather Apps and Live Data
Real-time weather data — including surface observations from nearby airports, radar imagery, and updated wind forecasts — can be accessed in flight via smartphone. While the pi-ball and direct observation remain primary tools, having access to meteorological data in the air adds another layer of situational awareness.
What Passengers Experience
From a passenger's perspective, the steering process is almost invisible. You will hear the burner fire periodically — a loud, impressive roar that lasts a few seconds at a time. You will feel the basket gradually rise or descend. You might notice the landscape below shifting direction as the pilot moves between wind layers.
But there is no jolting, no banking, no sudden changes of direction. The transitions between wind layers are gradual and smooth. Many passengers find the whole experience so gentle that they are surprised to learn the pilot has been actively navigating throughout, reading the wind and making dozens of small adjustments to keep the flight on a scenic and safe path.

Navigation in Competitive Ballooning
To truly appreciate the skill of balloon navigation, consider competitive ballooning. In events like the World Hot Air Balloon Championship, pilots must navigate to specific GPS coordinates on the ground and drop weighted markers as close to the target as possible. The best pilots routinely land their markers within a few metres of the target — a remarkable demonstration of what is achievable through wind reading and altitude management alone.
These competitions prove beyond any doubt that balloon flight is not random or uncontrolled. In the hands of a skilled pilot, a hot air balloon can be navigated with genuine precision, using nothing more than the three-dimensional wind patterns of the atmosphere.
Ready to See Wind Navigation in Action?
There is no better way to appreciate the art of balloon steering than to experience it first-hand. A sunrise flight over the Palmerie lets you watch an expert pilot read the wind, choose the altitude, and guide the balloon across the Marrakech landscape — all while you enjoy views of the Atlas Mountains, scattered Berber villages, and the palm groves below.
