787 Oral Questions Flashcards
What fuel is prohibited to use? (Obara)
JP-4 and Jet B (AOM L.3.9)
What items do you check on the status page in Preliminary Preflight Procedure? (Obara)
Verify only expected messages are shown. (AOM NP.31.1) Verify the following are sufficient for flight: *Oxygen pressure: DOM 860psi / INT 1250psi (AOM NP.21.2) *Hydraulic quantity: Quantity indication does not show RF (AOM NP.21.2) *Engine Oil quantity: At or above 16 quarts (AOM NP.21.2)
What is the difference of electrical system between B8 and B6? (Obara)
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.
What is the characteristic of B787 Engine? AOM 7.20.1 (Obara)
RR Trent 1000 3 Shaft, Hi Bypass Ratio Design with N1 Fan generating almost 90% of thrust. Thrust displayed by TPR 3 Shaft design helps to prevent compressor stall and shorten total length of the engine. Trent 1000-C rated at 69,800lbs of thrust The N2 (intermediate) rotor drives the engine accessory gearbox Each Engine controlled by an EEC (powered by dedicated PMA with backup from 115v AC
In which airport do you use the ALTN FWD CG? (Obara)
Use at airports with a short runway
What is ALTN FWD CG? (Obara)
Is a technique for improving takeoff performance on short runways by setting the forward limit of CG backwards.
What is Improved Climb? (Obara)
weight is Improved climb is a technique to increase the takeoff speed and subsequent initial climb speed and gradient when the runway is long enough. It can by used on long runways, when runway elevation is high or the OAT is high and takeoff limited by climb limit
What is OPT V1? (Obara)
Optimim V1 is a method of using unbalanced V1 to maximise the available accelerate/stop distance and minimise the Takeoff Run. There are cases where it is more effective to lift off at a short distance by making V1 larger than balanced V1 such as when there’s an obstacle in the immediate vicinity of the runway.
What is PECS? (Obara)
PECS Power Electronics Cooling System is a liquid cooling system for the large motor power distribution system located in the aft E/E compartment. It also provides liquid cooling to the supplemental cooling units and associated motor controllers of the Integrated Cooling System (AOM 2.20.14)
What is the merit and demerit of fly by wire? (Obara)
The system provides conventional control feel and pitch responses to speed and trim changes. It also provides enhanced handling qualities and reduced pilot workload. The primary flight control system is highly redundant with three operating modes; Normal, Secondary and Direct. (AOM Chapter 9 section 20) Requires and relies on electrical power More complex
What protections does B787 have? (Obara)
Bank angle Overspeed Stall (AOM 9.20.8) Flight envelope; The autopilot and auto throttle systems prevent stall and overspeed. Overspeed protection is available with flaps up for all modes except G/S. With flaps out of up, flight envelope protection is only available in FLCH and TO/GA AUTOPILOT EICAS caution displays if the autopilot has begun flight envelope protection or and amber line displays through the affected active roll or pitch flight mode annunciation. When engaged the autopilot limits bank angle to 30 further assisting flight enveloped protection. (AOM 4.20.27) Not available in Secondary or Direct modes
What does hydraulic system power? (Obara)
Nose gear steering Flaps and slats Landing gear Reversers Flight Controls (AOM Chapter 13 Section 20)
Turning Radius? Minimum required width? How to do it in 45m RWY? (Obara)
45.9m Procedure (AOM PT.1.1)
Which Items require “Confirmed Action”? (Obara)
Auto throttle arm switch Engine thrust lever Fuel control swith Engine or APU Fire switch, Cargo arm Switch Generator drive disconnect switch (QRH CI.2.12)
What are the company operational requirements for reduced thrust takeoff thrust?
(Okamoto)
