Definitions

Question 1

Va

Answer 1

Designed manuevering speed. The maximum speed at which abrupt, full deflection, control inputs will not will not cause the aircraft to exceed its G-force limit.

Question 2

Vfe

Answer 2

Maximum flap extended speed.

Question 3

Vle

Answer 3

Maximum speed at which the aircraft can be flown with the landing gear extended.

Question 4

Vlo

Answer 4

Maximum speed at which the aircraft may be flying while raising or lowering the landing gear.

Question 5

Vmc

Answer 5

The speed below control will be lost normally due to roll or yaw divergence. It is the minimum controllable airspeed with the critical engine inoperative.

Question 6

Vne

Answer 6

The speed that should never be exceeded due to structural failure or aeroelastic flutter or control oscillation

Question 7

Vr

Answer 7

The speed at which the pilot initiates rotation to obtain scheduled takeoff performance.

Question 8

Vno

Answer 8

Normal cruising speed of the aircraft. Maximum speed to be used in turbulent conditions

Question 9

Vref

Answer 9

Reference landing speed in calm air to be used at height of 50 ft. above the landing elevation.

Question 10

Vs

Answer 10

Stalling speed or minimum steady flight speed at which the airplane is controllable. Usually synonymous with Vs1. Varies with weight and balance.

Question 11

Vso

Answer 11

Stalling speed or minimum steady flight speed in the landing configuration.

Question 12

Vx

Answer 12

Best Angle of climb speed, provides the best altitude gain for horizontal distance. Usually used for clearing obstacles during takeoff.

Question 13

Vy

Answer 13

Best rate of climb speed. Provides the most altitude for unit of time.

Question 14

Vef

Answer 14

Speed at which the critical engine is assumed to fail during takeoff.

Question 15

V1

Answer 15

Minimum speed in the takeoff following a failure of the critical engine at Vef at which the pilot can continue the takeoff with the remaining engines. Problems after V1 are considered inflight emergencies. V1 is a determination of balance field length and is the max speed at which the pilot must take the first action in an abort to stop the airplane.

Question 16

V2

Answer 16

After takeoff speed following an engine failure for 2 segment climb to achieve performance specifications

Question 17

Region of Reverse Command

Answer 17

The region of flight speeds below max endurance speed (L/D max) where a decrease in speed requires an increase in power

Question 18

Vmu

Answer 18

The speed at which an airplane can rotate off the ground without experiencing a tail strike.

Question 19

What is CAS

Answer 19

Calibrated airspeed is indicated airspeed corrected for position and installation error.

Question 20

What is the best sequence of events to stop an aircraft upon landing

Answer 20

Reverse, spoilers, brakes

Question 21

Why does a swept wing aircraft roll if you step on the rudder?

Answer 21

The advancing wing will have a larger angle of attack.
