In-flight v dispatch. What runway condition reporting format do you use?
In-flight - GRF (General Reporting Format)
Dispatch - Contaminant Type
What does GRF stand for?
General Reporting Format
Standard Rev Thrust Selection for landing?
Reverse max. However on DRY runways the flight crew may select REV IDLE
On WET Runways (runway surface condition GOOD), the flight crew may select REV IDLE, if what conditions are met?
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
What is the limit for max and idle reverse thrust?
70kts and down to a stop for idle thrust
Is the use of auto brake preferable or not?
And is MAX auto brake recommended at landing?
Use of auto brake is preferable
No, Use of Max Autobrake is not recommended at landing
On short or contaminated runways, use what auto brake mode?
MED Mode
On long runways, what auto brake mode is recommended?
LO mode
On a wet or contaminated runway, what do Airbus recommend regarding reverse thrust?
MAX reverse thrust
On contaminated runways, can you takeoff with flex?
No, TOGA thrust only
Can we conduct FLEX takeoffs on wet runways?
Yes
What is the definition of a WET runway?
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
Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?
Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway
Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?
Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway
Can the use of reverse thrust be used in a takeoff perf calc, if the runway is WET?
Yes, but not allowed to takeoff at a weight higher than the weight on a dry runway
Is takeoff perf calculated with or without reverse thrust on a dry runway?
Without
Optimum landing config for green ops?
CONF 3 + Rev IDLE + BRK LO
VAPP is calculated by the FMS (displayed on the PERF page). How does it calculate VAPP?
What is the APP Correction?
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
When must a dispatch calc be performed?
Before every flight
When landing in heavy rain conditions, we should account for what?
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
When landing on WET runways Airbus recommend using MAX REV. To use idle, we must calculate what?
Performance based on MED-POOR (RWYCC2)
What is the rough mental math calc for Green Dot on the A320?
Weight x 2 + 85kts
What is VAPP?
Final Approach Speed: Speed over runway threshold, taking account of increments due to abnormal CONF or landing conditions
Green dot speed is?
Engine out operating speed in clean configuration. Best L-D ratio. Also corresponds to the final takeoff speed
S speed is?
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
F speed is?
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
VLS is?
Lowest selectable speed. 1.13 to 1.28 x VS, dependant on flap setting
VS is? And when is it displayed?
Stalling speed. Not displayed in normal law
If +RA is forecast, then a perf calc using what RWYCC should be used?
RWYCC2 - MED-POOR
