What are the minimum climb requirements?
Second segment 2.4%
Final segment 1.4%
What does OPT FL mean?
Cruise altitude for minimum cost when ECON Mach flown. Requires wind and temp profile entered. Depends on weight and ISA deviation.
FCTM and FCOM PERF
Do we correct Vapp for gusts? What is the maximum Vapp you can set?
In normal operations Vapp has a minimum value of VLS+5kts it will also take 1/3 of the headwind component disregarding any gusts. In strong or gusty crosswind conditions flight crew can increase up to a maximum of VLS + 15kts.
OMB descent preparation
Explain how ground speed mini works?
The purpose of the ground speed mini function is to keep the aircraft energy level above a minimum value, whatever the wind variations or gusts.
This allows an efficient management of the thrust in gusts or longitudinal shears. Thrust varies in the right sense, but in a smaller range (± 15 % N1) in gusty situations, which explains why it is recommended in such situations.
It provides additional but rational safety margins in shears.
This target speed is limited by VFE -5 in case of very strong gusts, by VAPP in case of tailwind or if instantaneous wind is lower than the tower wind.
This minimum energy level is the energy the aircraft will have at landing with the expected tower wind.
GS mini = VAPP - Tower head wind component
In order to achieve that goal, the aircraft ground speed should never drop below GS mini in the approach, while the winds are changing. Thus the aircraft IAS must vary while flying down, in order to cope with the gusts or wind changes. In order to make this possible for the pilot or for the A/THR, the FMGS continuously computes an IAS target speed, which ensures that the aircraft ground speed is at least equal to GS mini; the FMGS uses the instantaneous wind component experienced by the aircraft:
IAS Target Speed = GS mini + Current headwind component

Landing distance procedures –
When should you use “without reverser”
What multiple failures are you allowed to combine?
What do you do with failures that are marked with a star? Otherwise what do you do?
REV: select No Rev if IDLE or NO REV is planned, select MAX REV if they are planned to be used.
?.
What is VLS?
Lowest Selectable Speed: VLS As a general rule, during flight phases, pilots should not select a speed below VLS (Lowest Selectable Speed), defined as 1.23 VS1g of the actual configuration.
What is the required landing distance at dispatch?
The RLD is the demonstrated ALD multiplied by:
- 67 for a DRY runway.
- 92 for a WET runway.
Requirements
The maximum landing weight at an aerodrome, limited by RLD is the lower of:
1.
The maximum landing weight for the most favourable runway in still air;
2.
The maximum landing weight for the most likely runway to be assigned, taking into account the expected wind, the aeroplane ground handling characteristics and any additional considerations. If the requirements cannot be achieved at an aerodrome on the most likely landing runway with forecast wind, then dispatch is still permitted provided an alternate aerodrome is designated that allows full compliance with all the appropriate dispatch requirements.
If the requirements cannot be achieved at an aerodrome with a single runway in still air, due to dependence on a specific wind component, then dispatch is still permitted provided two alternate aerodromes are designated that allow full compliance with all the appropriate dispatch requirements.
