13.wheel-vs-three-point-landing. Wheel Landing vs. Three-Point Landing
Tailwheel airplanes can be landed using one of two primary techniques: the three-point landing and the wheel landing. Each is appropriate under different conditions, and a competent tailwheel pilot must be proficient in both. The choice depends on wind, runway surface, visibility over the nose, gross weight, and the handling characteristics of the specific airplane.
Three-Point Landing
A three-point landing places the airplane on all three wheels — main gear and tailwheel — simultaneously, with the airplane in the full-stall, three-point attitude. Because the wing is at or near its critical angle of attack at touchdown, airspeed is at minimum and the airplane has the least possible energy to dissipate during the rollout.
Procedure:
- Establish a stabilized final approach at the manufacturer's recommended airspeed, typically 1.3 V_SO.
- Begin the roundout at normal landing height; transition smoothly into the flare.
- Progressively increase back pressure so that airspeed bleeds off as the airplane settles.
- Touch down with the longitudinal axis aligned with the runway centerline, control wheel/stick coming fully aft as the mains and tailwheel contact simultaneously.
- After touchdown, hold the stick fully aft to keep the tailwheel firmly on the ground for steering authority, and use rudder to maintain directional control.
The three-point landing is preferred on short fields, soft or unimproved surfaces, and in light or calm wind. Because the airplane lands at minimum speed and in a high-drag attitude, the ground roll is shorter. The drawback is that forward visibility is poor in the three-point attitude, and the high angle of attack makes the airplane more susceptible to being lifted or weathervaned by gusts after touchdown.
Wheel Landing
A wheel landing touches down on the main wheels only, with the tail still flying, in approximately a level-flight attitude. The airplane is flown onto the runway at a slightly higher airspeed than a three-point landing, then the tail is allowed to lower aerodynamically as elevator effectiveness decreases.
Procedure:
- Fly the final approach at the manufacturer's recommended wheel-landing airspeed (typically a few knots faster than three-point speed).
- Roundout to a slightly nose-low or level attitude — lower than three-point.
- As the main wheels touch, apply a small, smooth amount of forward stick pressure to pin the mains to the runway and prevent skip or bounce. This effectively reduces the wing's angle of attack so the airplane will not become airborne again.
- Maintain directional control with rudder; let the tail settle of its own accord as airspeed decays.
- When the tailwheel touches, bring the stick fully aft and continue the rollout with normal tailwheel steering and braking as required.
The wheel landing is preferred in gusty winds, strong crosswinds, and turbulent conditions, because:
- The higher touchdown speed gives more positive control authority on the rudder, ailerons, and elevator.
- The lower deck angle improves forward visibility.
- The lower angle of attack reduces the chance of a gust lifting the airplane back into the air.
The trade-offs are a longer ground roll, greater required runway, and an unforgiving response to mishandling: any backpressure at touchdown will cause the airplane to balloon or bounce, and a bounced wheel landing can quickly progress into a porpoise if not corrected with a go-around.
Comparison Summary
- Touchdown attitude: three-point — full-stall; wheel — level/slightly nose-low.
- Touchdown speed: three-point — minimum; wheel — higher.
- Stick after touchdown: three-point — full aft; wheel — slight forward, then progressively aft.
- Best use: three-point — short/soft fields, calm winds; wheel — gusty/crosswind conditions, hard-surface runways with adequate length.
- Visibility over nose: three-point — poor; wheel — good.
- Ground roll: three-point — shorter; wheel — longer.
Crosswind Considerations
For either technique, the sideslip (wing-low) method is generally preferred over the crab method in tailwheel airplanes, because the airplane must touch down with its longitudinal axis parallel to the runway. Side load on the gear must be eliminated at the moment of touchdown, or the narrow geometry between the main gear and the airplane's center of gravity (which lies aft of the mains) will produce a swerve that can rapidly develop into a ground loop.
In a wheel landing, the upwind main is often allowed to touch first, followed by the downwind main, then the tail. Aileron deflection into the wind is increased progressively as the airplane decelerates, until full aileron deflection is reached at taxi speed.
Decision Factors
Use a three-point landing when minimum touchdown speed is the priority — short fields, soft fields, or rough terrain. Use a wheel landing when control authority and visibility are the priority — gusty winds, strong crosswinds, or when carrying a heavy load that requires a flatter approach. In all cases, the technique chosen must match the airplane, the conditions, and the pilot's currency in that specific airplane.
