1
Q

Regarding a Class A AC, describe what BR is?

A
  • BR: Brake release

- Start point of the AC take off

2
Q

Regarding a Class A AC, describe V1?

A
  • V1: decision speed
  • Speed at which the first action for an aborted take off must be made
  • Beyond V1 the AC WILL take off
3
Q

Regarding a Class A AC, describe Vef?

A
  • Vef: Velocity Engine Failure
  • The speed at which an engine failure is assumed to take place
  • Vef < V1 (min 1 sec before V1)
4
Q

Regarding a Class A AC, describe Vmcg?

A
  • Vmcg: Velocity minimum control on the ground

- Vmcg <= Vef

5
Q

Regarding a Class A AC, describe Vr?

A
  • Vr: Velocity Rotate

- Vr >= V1

6
Q

Regarding a Class A AC, describe Vlof?

A
  • Vlof: Velocity Lift Off

- Vlof > Vr

7
Q

Regarding a Class A AC, describe V2?

A
  • V2: Minimum speed the AC must be at 35ft (screen height)

- V2 > Vlof

8
Q

Regarding a Class A AC, describe Vmbe?

A
  • Vmbe: Velocity maximum brake energy absorption
  • Maximum velocity at which the brakes are still able to convert kinetic energy into heat energy
  • Vmbe >= V1
9
Q

Regarding a Class A AC, describe Vmax tyre?

A
  • Vmax tyre: Maximum velocity the tyres can handle

- Vmax tyre >= Vlof

10
Q

Regarding a Class A AC, in what order do the following speeds sit and how do they relate to each other:

  • Vef
  • Vr
  • V1
  • V2
  • Vlof
A

Vef < V1 <= Vr < Vlof < V2

11
Q

Regarding a Class A AC, at what point on a graph is it considered to be a Balanced V1?

A

The point where ASD and TODn-1 cross

12
Q

Regarding a Class A AC, how do the following effect V1 and Vmbe:

  • Upslope
  • Tailwind
A
  • V1 and Vmbe increase with an Upslope

- V1 and Vmbe decrease with a tailwind

13
Q

Regarding a Class A AC, in what order do the following speeds sit and how do they relate to each other:

  • V1
  • Vmbe
  • Vmcg
  • Vr
A

Vmcg < V1 <= Vmbe and Vr

14
Q

Regarding a Class A AC, if V1 is reduced what happens to:

  • T/O distance
  • ASD
A
  • T/O distance increases

- ASD decreases

15
Q

Regarding a Class A AC, if the Stopway is increased what happens to:

  • V1
  • TOM
A
  • V1 increased

- TOM increased

16
Q

Regarding a Class A AC, if the Clearway is increased what happens to:

  • V1
  • TOM
A
  • V1 decreases

- TOM increases

17
Q

Regarding a Class A AC, in what conditions are the following likely to be limiting for Vr:

  • Vmc
  • Vmu
A
  • In Hot and High Altitude conditions Vmu is most likely to be limiting
  • In Cold and Low Altitude conditions Vmc is most likely to be limiting
18
Q

What is the Take Off Run from and to on a wet runway?

A

From brake released to 15ft screen height

19
Q

As contamination on a RW increases, what happens to:

  • Mass decrement
  • V1 decrement
A
  • Mass decrement increases

- V1 decrement decreases

20
Q

For a balanced field, what can be said about the Field Limited Take-Off Mass?

A

There is only 1 defined V1 speed

21
Q

For a Class A AC, what is the effect of compacted snow on TODR and ASDR?

A
  • TODR stays the same as compacted snow has no effect on acceleration
  • ASDR increases
22
Q

What are the major considerations when establishing the tyre speed limit?

A
  • Rotation rate

- Temperature
