Do flaps increase takeoff distance?
Increasing flap angle increases the lift coefficient, and therefore reduces stalling speed and the required takeoff speed (the same lift will be created at smaller air speed due to greater lift coefficient). In the same time increased flap angle increases drag, reduces acceleration, and increases the takeoff distance.
When can I retract flaps after landing?
Once a positive rate of climb is established, the pilot should retract the flaps and landing gear (if equipped). It is recommended that takeoff power be maintained until reaching an altitude of at least 500 feet above the surrounding terrain or obstacles.
Which is the best flap configuration for short field?
In most POHs, the flap configuration for short-field is usually recommended as partial flaps, for instance 10˚ for C172. I remember the arguments are that full flaps would reduce the acceleration rate, and in no flaps the airplane would have to accelerate to higher speed to off the ground.
How to calculate normal takeoff ground roll on a long field?
How to calculate normal takeoff ground roll when the POH only has Short Field Takeoff tables? The Cessna 172S POH only has Short Field Takeoff Distance tables. How do pilots determine ground roll for a normal takeoff on a long field with hard surface?
Why are full flaps better than no flaps?
I remember the arguments are that full flaps would reduce the acceleration rate, and in no flaps the airplane would have to accelerate to higher speed to off the ground. In either case, the ground roll distance is longer than the optimal partial-flap configurations.
Do you look up the short field ground roll?
It’s either short field takeoff or referring to charts that don’t exist in the Cessna 172S POH. Do pilots look up the short field ground roll, apply the adjustment factor for headwind and apply another adjustment factor?
