What is improved climb ?
Improved climb is a technique to increase the takeoff speed by increasing the takeoff speed when the runway is long enough. From the viewpoint of rising ability, V2 is lower than the speed at which (T - D) becomes the maximum, that is, it is smaller than the maximum rising angular velocity (VX) as shown in the figure. That is, the rise gradient is larger when the speed is higher than normal V2. Therefore, if the take-off weight is limited by the rising ability of the 2nd segment, if there is a margin in the runway length, you can increase V2 to increase the rising slope of 2nd segment. That is, by increasing V2, climb limit weight can be increased. Also, if the obstacle is relatively far away, obstacle limit weight can also be increased. This is called improved climb performance. This method may be used when the runway length is long enough, when the runway elevation is high or the outside air temperature is high and the take-off weight is limited by climb limit. In improved climb performance, VR must also be larger than usual. In B787, we can use improved climb in principle because we can easily calculate the performance with OPT as optimum V1. In addition, the ANA Group has introduced improved climb to Narita → Mumbai B737-700.
Can IMP CLB be used anytime?
This method may be used when the runway length is long enough, when the runway elevation is high or the outside air temperature is high and the take-off weight is limited by climb limit.
In what case is it an advantage to use IMP CLB?
When the runway elevation is high or the outside air temperature is high and the take-off weight is limited by climb limit.
What are the company operational requirements for reduced thrust takeoff thrust?
AOR PR.10.2
In what case is the use of reduced thrust not available?
AOM SP.16.1
Whats is the Performace Allowance for a Reduced thrust take off? (Relationship between TEMP-WEIGHT-DISTANCE?)
AOR PR.10.3
Why do (would) you input ASM TEMP -5 Degrees C into the EFB?
AOR 10.2.13
What is the default setting for the ATM?
MAX
What is the merit of using Alternate C of G?
Alternate forward CG is a technique for improving takeoff performance on short runways by setting the forward limit of CG backward.
It is possible to use data with good takeoff performance to shorten the required runway length for the same takeoff weight and to set the maximum allowable takeoff weight for the same runway length.
By limiting the forward limit from (A) forward CG limit to (B) alternate forward CG limit, it is possible to improve takeoff performance on short runways.
Can you do a manual engine start?
The engines can only be started using the Autostart system. (AOM)
Except MEL 80-11-01 Start Selector Holding/Cutout Systems
What is the Auto Start Function?
Auto start allows the EEC to control fuel and ignition.
Which cases do not allow a second start?
- Loss of both starters
- No N1 Rotation
Are there any cases that you abort the engine start manually ?
Yes
- EICAS message
- ENG AUTOSTART L,R
- FIRE ENG TAILPIPE L,R
What Kind of engine start malfunctions can occur on the B787?
COMPRESSOR STALL HOT START HUNG START LOSS OF ONE STARTER NO EGT RISE START TIME EXCEEDS THE STARTER DUTY CYCLE TIME
What kind of Idle Thrust settings does the B787 have?
- Minimum
- Approach
- Icing
- Ice Crystal
What are the Unique limitations of the B787?
Please refer to AOM LIMITATIONS
What do you do if ECL is inoperative?
A Normal checklist needs to be completed.
AOM 10.60.15 / QRH 10.16
What are the Cautions / Threats while using the ELC?
Please have a think after using it !
What is on the front and back cover if the QRH?
Front – Quick Action Index
Back – EVACUATION CHECKLIST
Q.What is the difference of electrical system between B8 and B6?
Electrical System: (AOM 6.20.1)
System powers engine start, pressurization, wing ice protection, stabilizer trim and wheel brakes.
2x Starter/Generator on each engine and APU giving total of 6.
B787 main buses are 235Vac.
3x independent PMG to power primary flight controls
2x independent PMA to power EEC
3x External Power Receptacles.
Batteries are Lithium.
When does the Emergency landing should be considered?
AOM CI.2.3 QRH
the non-normal checklist contains the phrase “Plan to land at the nearest suitable airport”
smoke/fumes or fire started in the cabin or crew rest compartment and its elimination is unable to be confirmed.
there exists only 2 AC power source remaining. (2 main engine generator only,or 1 main engine generator + both APU generator)
Altimeter malfunction occurs, and the correct altitude cannot be confirmed by related procedures, standby altimeter, etc. (In this case contact ATC immediately and follow instructions)
