Normal and Crosswind Takeoff and Climb

Full power, low altitude and very little time: the takeoff is where the airplane stops belonging to the runway and starts belonging to the wind. What you will do if something breaks has to be settled before you release the brakes.

Takeoffs, Landings and Go-Arounds — FI.VII.A

Why the takeoff is worth a whole lesson

Almost nothing about the airplane stays constant while it happens. Control response builds as you accelerate, the left-turning tendencies build with it and shift again as the nose comes up, and the runway that looked generous from the hold short line is being spent the whole way down it. Each of those moves on its own schedule and none of them waits for you to catch up, which is why the thinking gets done on the ground and the flying gets done from memory.

It also teaches a fact that governs everything else you fly. On the ground the wind pushes on an airframe the wheels have tied to the earth. The instant the wheels leave, the airplane belongs to the air mass and moves with it — drift starts at lift-off, and the inputs that were right a second ago are wrong. Making that handover smoothly is most of what a crosswind takeoff is about.

Check, configure, brief

Check what the airplane can do today. Work the takeoff and climb performance out of the POH for today's weight, runway, temperature and elevation. High density altitude cuts engine and propeller output, lengthens the ground roll and flattens the climb — all three at once — so a runway that felt generous in winter may not be. Then check the wind, which sets your runway, your crosswind technique, and whether wind shear, a tailwind or wake turbulence needs thinking about. Wind direction is the direction it blows from. Take it from the ATIS, the METAR and the windsock — and believe the windsock, the only one reporting at your end of the field right now.

Configure before you roll onto the runway: engine instruments where they belong, controls free and correct, flaps and trim set. The pre-takeoff checklist finishes at the hold short line, not the centerline.

Brief the departure out loud, and make it about what you do when something breaks. There are two answers in it: where the airplane goes if the engine quits with runway still ahead of you, and where it goes if it quits once you are airborne. Both depend on departure path, altitude, wind and terrain — a different answer at every airport. Getting there counts too: read back the clearance, stay oriented, and clear the final before you taxi into position.

The ground roll

Line up and confirm the runway is the one you were cleared for — heading indicator against the runway number, every time. Advance the throttle smoothly to full power. Smoothly is not politeness: a slammed throttle makes the left-turning tendencies arrive all at once, and the more horsepower the harder it yanks. Check the engine instruments once power is set, then look outside and stay outside.

Steer with your feet. In the typical trainer, whose propeller turns clockwise as seen from the cockpit, torque, P-factor and spiraling slipstream all pull the nose left as the airplane accelerates, and in a tailwheel airplane gyroscopic precession joins them as the tail comes up. Those forces change with speed and power, so rudder pressure keeps changing rather than being set once. Look far down the runway, not over the nose — distance lets you see yaw and drift early enough to fix them with small inputs.

Rotation and lift-off

At the rotation speed in your POH, raise the nose smoothly to the takeoff attitude and let the airplane fly itself off. Over-rotating drags it into the air at a high angle of attack with nothing in reserve; rotating late wastes runway. The attitude you want is a sight picture — a relationship between cowling and horizon that you learn by looking, and that the airspeed indicator only confirms.

The initial climb

The climb begins the moment the airplane leaves the surface with a climb attitude established. Stay coordinated: at full power in a climb attitude the left-turning tendencies are still working, and easing off the right rudder lets the nose yaw left and the airplane go uncoordinated. Two climb speeds matter, both from your POH. Vx, best angle, buys the most altitude per foot of ground covered — it is the obstacle speed. Vy, best rate, buys the most per minute, and is what you use when nothing is in the way. Normally you accelerate to Vy and hold it on attitude and visual references, tracking the extended centerline. Trim off the pressure; an untrimmed climb becomes pitch oscillations and a pilot sawing at the airspeed indicator. Flaps and the after-takeoff checklist come where your POH says.

When the wind is not down the runway

Taking off straight into the wind is the ideal, and often not the option. A crosswind takeoff is the same maneuver with a wind that will not cooperate, and it shows up in three places: the ground roll, the lift-off, and the first part of the climb.

On the ground, start with the aileron fully deflected into the wind. That raises the aileron on the upwind wing and holds it down — the crosswind is trying to lift that wing and roll you downwind, and at low speed full deflection is all you have to argue with. As you accelerate the controls bite harder, so you take aileron out gradually, leaving only enough to keep the airplane laterally centered, judged from what you see outside. Hands and feet have separate jobs: the rudder keeps the nose parallel to the centerline, the ailerons keep you over it.

At the lift-off, expect slightly less takeoff performance, since deflected surfaces are drag. In gusty conditions or a strong crosswind the Airplane Flying Handbook accepts leaving the ground at slightly more than the normal lift-off speed, so that you have firmer control the moment you are airborne; how much, if any, is a question for your POH and your instructor rather than a rule of thumb. What that is not is a reason to pin the airplane down. Held on the wheels past flying speed it takes side loads through the tires, tends to wheelbarrow onto the nosewheel, and eats runway you may want later. As the nosewheel comes up, keep the aileron in. The downwind main may lift first, leaving you briefly on the upwind wheel — acceptable, and better than side-skipping the tires across the pavement.

Then comes the handover. Once you are off, the sideslip only costs performance: level the wings and turn into the wind just enough to hold the centerline, trading the slip for a crab.

Work the component out before you go with the crosswind calculator, and compare it against the maximum demonstrated crosswind component in your POH. Know what that number is: the strongest crosswind in which the type was shown to be controllable during certification testing, by a test pilot, in a new airplane. It is not a certificated limitation and it is not a promise about you on the day. Your own limit will usually be lower, and it is allowed to be. When the computed component is more than the airplane's figure or more than yours, the answer is a different runway, a different airport, a later hour, or not going.

The cost of getting that boundary wrong is not theoretical. Draco, a heavily modified Wilga bush airplane, was destroyed at Reno–Stead in September 2019 after losing control during an attempted takeoff in a gusty crosswind; everyone aboard walked away and the airplane never flew again. That was a very experienced pilot in an unusual airplane, so the lesson is not a technique you could copy. It is that a gusty crosswind is a condition you are allowed to decline, and that declining it costs nothing on the ground.

What goes wrong

The same errors repeat from student to student. A jerked throttle and the swerve that follows. Not anticipating the left turn, or stamping past it. Staring at the airspeed indicator instead of learning what the runway and horizon look like at flying speed. Lifting off in the wrong attitude, then over-controlling in pitch and never trimming. Narrowing the scan to straight ahead, so a wing drops after lift-off before you notice.

In a crosswind: less than full aileron to begin with, aileron moved mechanically rather than by watching where the airplane is, side-skipping, too little rudder to hold the nose straight, and no drift correction once airborne.

Where you meet it next

On the checkride this is the first task in Takeoffs, Landings and Go-Arounds, and the examiner watches the ground roll and the wind correction as closely as the numbers. Its mirror image is the normal and crosswind approach and landing, where the same slip-versus-crab decision runs in reverse and has to be settled before the wheels touch. The short-field and soft-field takeoffs are this maneuver with one variable made harder, and the go-around is the climb you have just flown, begun from a worse place. The planning that opens this lesson comes back on every hot afternoon at altitude, and all of it sits alongside the rest of the ground school lessons.
