Question 6

In-flight v dispatch. What runway condition reporting format do you use?

Answer 6

In-flight - GRF (General Reporting Format)

Dispatch - Contaminant Type

Question 7

What does GRF stand for?

Answer 7

General Reporting Format

Question 8

Standard Rev Thrust Selection for landing?

Answer 8

Reverse max. However on DRY runways the flight crew may select REV IDLE

Question 9

On WET Runways (runway surface condition GOOD), the flight crew may select REV IDLE, if what conditions are met?

Answer 9

A landing distance assessment has been made with the following parameters:
1. Med to Poor ldg perf level for the in-flight landing distance computation
2. No reverser credit
3. The result of this landing distance assessment is within the LDA

Question 10

What is the limit for max and idle reverse thrust?

Answer 10

70kts and down to a stop for idle thrust

Question 11

Is the use of auto brake preferable or not?

And is MAX auto brake recommended at landing?

Answer 11

Use of auto brake is preferable

No, Use of Max Autobrake is not recommended at landing

Question 12

On short or contaminated runways, use what auto brake mode?

Answer 12

MED Mode

Question 13

On long runways, what auto brake mode is recommended?

Answer 13

LO mode

Question 14

On a wet or contaminated runway, what do Airbus recommend regarding reverse thrust?

Answer 14

MAX reverse thrust

Question 15

On contaminated runways, can you takeoff with flex?

Answer 15

No, TOGA thrust only

Question 16

Can we conduct FLEX takeoffs on wet runways?

Answer 16

Yes

Question 17

What is the definition of a WET runway?

Answer 17

Considered WET when the surface is covered by any visible moisture or water up to and including 3mm depth. When water film does not exceed 3mm, there is no significant danger of hydroplaning

Question 18

Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?

Answer 18

Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway

Question 19

Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?

Answer 19

Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway

Question 20

Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?

Answer 20

Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway

Question 21

Is takeoff perf calculated with or without reverse thrust on a dry runway?

Answer 21

Without

Question 22

Optimum landing config for green ops?

Answer 22

CONF 3 + Rev IDLE + BRK LO

Question 23

VAPP is calculated by the FMS (displayed on the PERF page). How does it calculate VAPP?

What is the APP Correction?

Answer 23

VLS + APPR COR (APP Correction)

   APPR COR is the highest of;
          -5kts in the case of A/THR ON
          -5kts in the case of ice
          accretion in CONF FULL
          -10kts in case of ice 
          accretion in CONF 3
           -1/3 HD wind (excluding gusts 
           MAX of 15kts

Question 24

When must a dispatch calc be performed?

Answer 24

Before every flight

Question 25

When landing in heavy rain conditions, we should account for what?

Answer 25

The possibility of standing water MED-POOR (RWYCC2). If +RA is forecast then a calc using MED-POOR would be worst case and covers the runway degradation of +RA is encountered

Question 26

When landing on WET runways Airbus recommend using MAX REV. To use idle, we must calculate what?

Answer 26

Performance based on MED-POOR (RWYCC2)

Question 27

What is the rough mental math calc for Green Dot on the A320?

Answer 27

Weight x 2 + 85kts

Question 28

What is VAPP?

Answer 28

Final Approach Speed: Speed over runway threshold, taking account of increments due to abnormal CONF or landing conditions

Question 29

Green dot speed is?

Answer 29

Engine out operating speed in clean configuration. Best L-D ratio. Also corresponds to the final takeoff speed

Question 30

S speed is?

Answer 30

T/O - min speed at which the slats may be retracted at takeoff

LDG - in approach, used as a target speed when the aircraft is in CONF 1

Question 31

F speed is?

Answer 31

T/O - min speed at which flaps may be retracted at takeoff

LDG - in approach, used as a target speed when the aircraft is in CONF 2 or CONF 3

Question 32

VLS is?

Answer 32

Lowest selectable speed. 1.13 to 1.28 x VS, dependant on flap setting

Question 33

VS is? And when is it displayed?

Answer 33

Stalling speed. Not displayed in normal law

Question 34

If +RA is forecast, then a perf calc using what RWYCC should be used?

Answer 34

RWYCC2 - MED-POOR
