05 NORMAL LANDING
– Aim to cross the runway threshold with 70 kts
– Flare to a slightly nose-up attitude and retard the power levers smoothly to idle.
– Do not prolong the flare.
– After touchdown on the main wheels keep the nose wheel off the ground as long as
possible to avoid shimmy.
06 CROSSWIND LANDING
On final approach maintain runway alignment by crabbing into the wind.
Just prior to touchdown, apply rudder to align the aircraft with the runway center line and
bank into the wind to counteract drift (3° to 5° bank angle).
– Do not delay touchdown after decrabbing is completed.
– After landing, keep straight with rudder and counteract the tendency of the upwind wing
to lift by decisive use of aileron.
07 LANDING ON CONTAMINATED/SLIPPERY RUNWAY
The landing and deceleration on a contaminated runway where reduced braking action or
risk of hydroplaning exists, must always be considered critical. A high speed landing on a
contaminated runway with no headwind or a tailwind greatly increases the possibility of
hydroplaning.
In case of heavy rain or thunderstorms, delay the landing until weather and runway
conditions improve.
Runway selection
The runway must be long enough to allow a reasonable margin above the normal landing
distance, taking into account the braking action and the type of runway contamination.
Approach
The approach must be flown using the normal techniques. The threshold must be crossed
at the correct speed.
Flare and Touchdown
Avoid floating and make a positive landing to assure wheel spin-up.
Deceleration
Start wheel braking not sooner than 2-3 seconds after the main wheels are firmly on the
runway and initially apply light brake pressure, gradually increasing as speed is reduced.
If no brake pressure is felt, expect hydroplaning. Release brakes completely for 2-3
seconds to allow the wheels to spin-up, then apply light brake pressure again.
