| Hint | Answer | % Correct |
|---|---|---|
| Upper boundary of the white arc; maximum speed with the wing flaps extended. | Vfe | 77%
|
| Upper boundary of the yellow arc, red line; never exceed this speed. | Vne | 77%
|
| Upper boundary of the green arc, lower boundary of the yellow arc; only exceed this speed in smooth air and exercise caution beyond this speed. | Vno | 69%
|
| The lower boundary of the white arc; stall speed at landing configuration. | Vs0 | 69%
|
| The lower boundary of the green arc; stall speed at particular configuration. | Vs1 | 69%
|
| Rotation speed; the speed during the takeoff roll at which the pilot should begin to apply back pressure to lift the aircraft off the ground. | Vr | 62%
|
| Maximum maneuvering speed (does not correspond with specific marking), which can be calculated by multiplying the stall speed by the square root of the limit load factor. | Va | 46%
|
| Maximum speed with the landing gear extended (does not correspond with specific marking) on planes with retractable landing gear. | Vle | 46%
|
| Speed for best angle of climb (does not correspond with specific marking), in which the airplane gains the most altitude in the least amount of distance. | Vx | 46%
|
| Speed for best rate of climb (does not correspond with specific marking), in which the airplane gains the most altitude in the least amount of time. | Vy | 46%
