Do flaps need to be up or down when taking off?
On takeoff, we want high lift and low drag, so the flaps will be set downward at a moderate setting. During landing we want high lift and high drag, so the flaps and slats will be fully deployed.
Are flaps retracted during takeoff?
Flap retraction is part of the takeoff and climb out procedure. Flaps are extended on the ground before takeoff to increase the lift at low speeds. Once the aircraft has achieved a stabilized climb and a safe airspeed and altitude, the flaps are retracted to achieve the optimum lift and drag configuration.
What happens to stalling speed when flaps are lowered?
Reduced Stall Speed With Flaps Extending flaps reduces your aircraft’s stall speed for a fairly simple reason. Because your wing creates more lift with the flaps down, you don’t need as much angle-of-attack to balance the four forces of flight.
Can a Cessna take off with full flaps?
While the Super Cub does call for full flaps on a STOL take off, the Cessna 182 in later POHs has 20 degrees max flap for take off. Sparky Imeson recommended flap extension aligned with full aileron deflection, in fact around 20 degrees.
What is stall speed?
Definition. Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.
Does stall speed increase with flaps?
Flap increases lift and therefore the stalling speed is reduced. However, flap also changes the shape of the wing, and this results in a lower nose attitude at the stall.
How fast are you going when you take off in a plane?
Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH. As a general rule, airspeed is measured according to the velocity of the plane as it flies through the air.
Will a Cessna 150 climb with full flaps?
Early Cessna 150s and 172s, for instance, were notoriously unable to gain speed with full flap; you had to bleed the flap up very carefully while you waited for the diminishing drag to allow the airplane to very gradually accelerate. If you had to turn or climb to avoid an obstacle, you were in a bad fix.
Will a Cessna 150 fly with full flaps?
A Cessna 150 has nearly the same trim setting for level cruise flight as is needed at 1500 RPM, full flaps and 60 kts descent. Thus, the full flap short approach requires no change in trim unless power is off.
How to start the engine on a Cessna 152?
– Turn off the hand brake and increase the throttle about 50%. Wait for it to rev-up. – The plane will start to veer to the left so keep control of it. – Keep Increasing the throttle and when you reach 50-55 knots on the air speed indicator, hold back the throttle a little bit and take off into the air.
What is the best glide speed for a Cessna 152?
What is the best glide speed for a Cessna 152? The best rate-of-climb speed is used to gain maximum altitude in minimum time, while the best angle-of-climb speed is used to gain maximum altitude in minimum distance. For example, a Cessna 152 has a 725-fpm sink rate when flying at its normal glide speed of 61 knots.
What is the stall speed of a Cessna 150?
Stall speed: 42 kn (48 mph, 78 km/h) (flaps down, power off) Never exceed speed : 140 kn (160 mph, 260 km/h) Range: 420 nmi (480 mi, 780 km) (econ cruise, standard fuel)
How fast is a Cessna 152?
To test a 152’s ability to keep you current, we rented one at Naples Air Center in Naples, Florida, and kept the speed up to 90 knots while making approaches to airports in the area. There was no difficulty at all with making approaches at that speed, a speed common to many larger singles.
