Three questions from the free preview. Think of your answer first, then open the explanation.
1.Which pressures do the ADIRU and SAARU use to calculate airspeed?
- A.Pitot pressure only
- B.Pitot and static pressure
- C.Static pressure only
Show answer and explanation
Correct answer: B. Pitot and static pressure
Airspeed comes from the difference between pitot and static pressure. Ref AMM 34-11-00.
2.Where does the 777 pitot-static system get static pressure?
- A.Static ports on the engine cowls
- B.Flush static ports on the fuselage
- C.Static holes on the pitot probes
Show answer and explanation
Correct answer: B. Flush static ports on the fuselage
Static pressure comes from flush static ports on the fuselage. Ref AMM 34-11-00.
3.How are the static ADMs and SADMs connected to the static ports?
- A.One left and one right port, joined
- B.All left and all right ports grouped
- C.Each module to its own static port
Show answer and explanation
Correct answer: A. One left and one right port, joined
One left and one right port are tubed together and then connected to the module, cancelling sideslip effects. Ref AMM 34-11-00.
