A

ASDA=TODA

Accelerate Stop Distance Available =
Take off Distance Available

7
Q

What can the TODA never be greater than?

A

150% of TORA

8
Q

How many seconds are factored into CS-25 regs to allow for a pilot to action the rejected T/O drills and for the aircraft to begin stopping?

A

2 seconds action time

9
Q

What is the correct order of speeds during T/O? Assuming engine failure at most critical point.

A

VMCG, VEF, V1, VR, V2

10
Q

Airfield elevation is 350ft and QNH 1005. What is the pressure altitude?

A

590ft

11
Q

Airfield elevation is 2500ft and OAT 20degrees Celsius. What is the ISA temperature elevation?

A

ISA + 10 degrees celcius

12
Q

What is the vertical obstacle clearance required during the NET flight path climb during a turn with more than 15 degrees AOB?

A

50 ft

13
Q

What is the vertical obstacle clearance required during the NET flight path climb during a straight out climb?

A

35 ft

14
Q

When calculating the width of the obstacle domain, what is the maximum value of D if navigation accuracy is sufficient and the track change is more than 15 degrees?

A

600m

15
Q

During the T/O climb what is the minimum height below which no changes in aircraft flap configuration are permitted?

A

A minimum height of 400 ft gross above the airfield reference zero.

16
Q

Where does the T/O stage of performance begin and end?

A

Begins at the Brakes release point.

Ends when the aircraft passes through regulated screen height.

17
Q

What does the TODR comprise of?

A

The T/O ground roll and the airborne distance covered until passing the screen height.

18
Q

For T/O planning, what proportion of a headwind component must be considered?

A

50%

19
Q

For T/O planning, what proportion of a tailwind component must be considered?

A

150%

20
Q

What is the rectangular area beyond the end of the runway, deemed clear of obstacles and suitable for the initial climb to be a specified screen height called?

A

Clearway

21
Q

What is the defined screen height for Performance Class A aeroplanes?

A

35ft dry, or 15ft wet

22
Q

Define VSTOP?

A

The max speed during T/O at which it is possible to abort the T/O following failure of a critical engine

23
Q

Define VGO?

A

The minimum speed during T/O at which it is possible to continue T/O following failure of a critical engine.

24
Q

What represents the max value for V1?

A

25
Q

If unaffected by obstacles, where does the NFP normally end?

A

When the aircraft attains a safe height of 1500ft above surface datum.

26

30
Q

What are the conditions for a non-ETOPS approved twin aircraft?

A

It must never be more than 60minutes flying time on one engine in still air and ISA conditions form a suitable diversion airfield.
