AA1205 Takeoff & Landings Flashcards
How is Takeoff performance affected by RCR
no affect
How is Landing performance affected by Weight
higher Touchdown speed and landing roll
How is Landing performance affected by Flaps
Lower Touchdown speed and landing roll
How is Landing performance affected by temperature
increases landing roll
How is Landing performance affected by pressure altitude
increases landing roll
How is Landing performance affected by winds
head winds decrease roll and tailwinds increase roll
How is Landing performance affected by RCR
No affect on aerobrake but decreases effectiveness of normal braking, thus inceasing landing roll
How does ground effect change aerodynamic forces
more lift and less induced drag
What height does ground effect occur
1/2 the wingspan
What is the max speed for optimum braking
100 KCAS
Between 130 and 100 KCAS, what type of breaking should be used
Cautious
What can happen when optimum braking is applied above 100 KCAS
locked wheels, skidding, tire failure, and loss of directional control
How long should you aerobrake
from touchdown until just prior loss of elevator authority (approx 100-120 KCAS)
After aerobraking, how should you apply brake and for how long
cautious or moderate until below 100 KCAS
Below 100 KCAS what kind of braking should you use
optimum
Can you use wheel brakes while aerobraking
No
How long should you wait after nosewheel touchdown after aerobraking to start applying wheel brakes
no delay
After a heavyweight landing or high speed abort, what situation can occur
hot brakes
What nose high attitude is considered full aerobraking
12 degrees nose high
With crosswinds above 15 knots, what kind of aerobraking is used
None
does aircraft weight have an effect on the speed of hydropaning
No
What is the main factor in determining the speed of hydropaning
air pressure in the tires
Will the speed of hydropaning be higher or lower if the wheel is not spinning
hydroplaning can occur at lower speeds
When landing on a wet runway, what kind of landing will help avoid hydroplaning
firm touchdown
When on a landing roll on a wet runway, what kind of braking should we use and what should you do if you start hydroplaning
cautious braking, release brakes and apply slower
Best way to deal with hydroplaning
avoid it
