Performance

Question 1

What is Vmcg ?

Answer 1

Minimum control speed on ground

The speed at which when the critical engine is suddenly made inoperative it is possible to maintain control of the aeroplane. (Within 30ft)

Question 2

What is Vmca?

Answer 2

Minimum control speed in the air.

The speed at which when the critical engine is suddenly made inoperative it is possible to maintain control of the aeroplane. (Bank angle no more than 5).

Vmca has to be less than 1.2Vs

Question 3

What is Vmcl?

Answer 3

Minimum control speed during approach and landing.

The speed at which when the critical engine is suddenly made inoperative it is possible to maintain control of the aeroplane.

Question 4

What is a Vmu?

Answer 4

Min unstick speed

Question 5

What is VLOF?

Answer 5

The speed at which the aeroplane first becomes airborne .

Lift overcomes weight.

Question 6

What is V2?

Answer 6

The minimum climb speed that must be reached at a height of 35 feet above the runway surface, in case of an engine failure.

Question 7

What is VMBE ?

Answer 7

Max brake energy speed.
The speed at which after an accelerate stop the brakes can safely bring the aircraft to a stop by the runway end.
V1<=VMBE

Question 8

VTire

Answer 8

Max tire speed

195kts

Question 9

What is screen height dry and wet?

Answer 9

Dry 35ft
Wet 15ft

Screen height is the height at the end of the TOD.

Question 10

What is:
TORA
TODA
ASDA

Answer 10

TORA - Take off run available

TODA - Take off distance available, TORA plus Clearway.

ASDA - Accelerate Stop Distance Available.
TORA plus Stopway.

Question 11

How long can we use TOGA for on take off?

Answer 11

2 engines - 5 minutes

1 engine - 10 minutes

Question 12

What is the aquaplaining formula?

Answer 12

Vaquaplaning (kts)

=

34 √Tire pressure/specific gravity of contaminant

Question 13

Are reverses assumes for ASD?

Dry, wet , contaminated?

Answer 13

Dry - no

Wet/contaminated - yes

Question 14

How far away can a take off alternate be?

Answer 14

One hour flight time at the one eng inop cruising speed in still air.

Question 15

What is Vls?

Answer 15

Lowest selectable speed
=1.23 Vs1g

1.23 x the stall speed in 1g flight

Question 16

What is V app.

What is it made of?

Answer 16

Final approach speed

Vapp = Vls + wind correction

Question 17

What is V REF in the QRH?

Answer 17

Vls in config full

Question 18

Take off, Second segment climb gradient ?

Answer 18

2.4%

Question 19

Take off, final segment climb gradient?

Answer 19

1.2%

Question 20

Go around, approach climb gradient? One engine inop

Answer 20

2.1%

Question 21

Landing climb gradient ? All engines operating

Answer 21

3.2%

Question 22

How do we calculate ROD for an SRA approach that requires us to use hdg and vertical speed?

Say our ground speed is 130 kts and its a 3.6 degree slope, what should our v/s selection be?

Answer 22

ROD = %gradient x groundspeed

%gradient= 1.7 x FPA

So, ROD = 1.7 x FPA x groundspeed

ROD= 1.7 x 3.6 x 130 = (2x3x130)= 780=800fpm call it.

For a 3 degree angle , 3x1.7 = 5 hence the 5 x groundspeed rule usually.
