V Speeds

Question 1

Vr relationship to Vmca

Answer 1

Must be no less than 1.05 times Vmca to ensure directional control

Question 2

V2 relationship to Vmca and Vs

Answer 2

1.1 times Vmca and no less than 1.2 times Vs

Question 3

Vef relationship to V1

Answer 3

Engine Failure is considered to have happened 1sec prior to V1

Question 4

ASDR

Answer 4

Find by adding distance to engine failure and Distance to stop

Question 5

Balanced Field Length

Answer 5

Point on graph of Distance vs Speed, where ASDR and TODR intercept and are equal. It is a given speed for a weight and atmospheric conditions

Question 6

1st segment for Take Off

Answer 6

From 35ft to when gear is up.. Power and Flap at T/O and gear is RETRACTING

Question 7

2nd segment

Answer 7

Take off thrust and flaps still set to height of at least 400ft and at V2. 2.4% gradient gross and 1.6% net

Question 8

Third segment

Answer 8

Two parts, part 1, from 400ft to when flaps are retracted, speed from V2 to Vfl, Part 2 While flips are retracting from Vfl to Vcl.

Question 9

4th Segment

Answer 9

From end of 3rd segment to gross height of at least 1500’ with flaps up and continuous thrust set
