Aero 3: Performance Characteristics Flashcards
What is the takeoff airspeed in terms of stall speed?
The minimum airspeed for takeoff is 20% above the power-off stall speed.
What is the landing airspeed in terms of stall speed?
The airspeed for landing is 30% above the power-off stall speed.
Max Angle of Climb
Max vertical velocity for minimum horizontal velocity
Max altitude increase in shortest horizontal distance
Max Rate of Climb
Max vertical distance gained in the shortest amount of time
Max altitude increase in the shortest time
Max Range
The farthest distance an airplane can fly on a given amount of fuel
Max endurance
The maximum time that an airplane can fly on a given amount of fuel
What power settings do you need to fly at max endurance profile?
(Velocity & AOA)
- Velocity below L/Dmax
- AOA greater than L/Dmax AOA
What power settings do you need to fly at max glide endurance profile?
(Velocity & AOA)
- Velocity below L/Dmax
- AOA greater than L/Dmax AOA
What power settings do you need to fly at max range profile?
(Velocity & AOA)
*At L/Dmax AOA and velocity
What power settings do you need to fly at max glide range profile?
(Velocity & AOA)
*At L/Dmax AOA and velocity to minimize drag
What affect does an increase in altitude have on max range performance?
An increase in altitude improves max range
Lower temps at higher altitudes makes engine more fuel efficient which lowers fuel burn per mile, so it can fly a farther distance
What effect does an increase in altitude have on max endurance performance?
An increase in altitude improves max endurance
Lower temps at high altitude makes engine more fuel efficient which lowers fuel burn, so plane can stay in the air longer
At what region of the power curve is normal command located?
Normal command takes effect at velocities above max endurance
At what region of the power curve is reverse command located?
Reverse command takes effect at velocities below max endurance
What is the relationship between velocity and throttle settings in normal command?
Velocity and throttle settings are directly related
To fly faster, more throttle is needed
