  • 85 degree in pitch and roll
  • 360 in roll and 110 in pitch
  • 360 in roll and 85 in pitch
shinkosensei asking:

A/H or A/P?

Module 13. Aircraft aerodynamics, structures and systems

In a dual FMS, a failure of one computer will result in

  • COMPLETELY blank display on one CDU
  • down-grade of the landing category
  • no effect on the CDU
sam612 asking:

In other QA it indicated that 'COMPLETELY blank display on one CDU' was the correct answer ??

Module 13. Aircraft aerodynamics, structures and systems

Aircraft is 9000 ft. When is it out of VHF range

  • 100 nm
  • 120 nm
  • 140 nm
hkcasper asking:

pls correct me if i m wrong , square foot of 9000 x 1.23 , answer should be 120 nm instead of 140nm?

Module 13. Aircraft aerodynamics, structures and systems

In ADF system, Goniometer

  • combines the signals from fixed loop antenna and sense antenna
  • effectively simulates a rotating loop antenna
  • alternately selects signals from loop antenna and sense antenna
sasna asking:

goniometer is used with fixed loop antenna....???????

Module 13. Aircraft aerodynamics, structures and systems

Paralleling in AC constant frequency is affected by

  • contactors
  • Generator Control Unit (GCU)
  • But Tie Bar (BTB)
sasna asking:

I fail to interpret the question...BTB has a different role to play,,,,,???/

Module 13. Aircraft aerodynamics, structures and systems

The maximum azimuth coverage by a MLS facility is

  • +/- 35 degrees
  • +/-40 degrees
  • +/-60 degrees
sasna asking:

pls confirm i am aware of +/- 40

Module 13. Aircraft aerodynamics, structures and systems

Versine signal is governed by

  • roll
  • pitch
  • yaw
nairs asking:

NOT TOO SURE ABOUT IT ....PITCH LOOKS TO BE MORE CORREST

Module 13. Aircraft aerodynamics, structures and systems

In a combined pitot-static probe, while carrying out a leak check, which instrument is most likely to be effected by over pressure?

  • ASI
  • VSI
  • Altimeter
nairs asking:

MY ANSWER IS ASI

Module 13. Aircraft aerodynamics, structures and systems

The loss of the vertical gyro signal to the flight director system would cause

  • aircraft to underbank
  • aircraft to overbank
  • aircraft to remain in level flight
nairs asking:

acft. to remain in level flt. as there is no input for pitch and roll

Module 13. Aircraft aerodynamics, structures and systems

Automatic trim is used to

  • maintain level flight
  • prevents standing loads on the elevator
  • allow full authority to be regained by the aileron
Gibbo280490 asking:

MAINTAIN LEVEL FLIGHT?

Module 13. Aircraft aerodynamics, structures and systems

Medium vibration of 4 to 6 times per revolution is experienced on a helicopter. The primary control method is

  • inspect loose fixtures and fittings
  • design of engine and gearbox supports
  • inspect main rotor head and main drive shaft
sam1969 asking:

I selected
-Design of engine and gearbox supports
Medium and High frequency Vibrations – Depending on the helicopter the source may be engine and transmission cooling fan and accessories such as air conditioner compressors, or driveline components.
Any ideas?

Module 13. Aircraft aerodynamics, structures and systems

A GNS satellite system transmis

  • vertically polarise
  • horizontally polarise
  • right hand circular
Vishallalli asking:

Please write your comment here.

Module 13. Aircraft aerodynamics, structures and systems

To improve the image or picture when using the WRX (weather radar receiver)

  • scan at a lower rate
  • use shorter bursts
  • use longer bursts
Jordi asking:

i think this is wrong my notes from my academy say 'scan at lower rate" .

Module 13. Aircraft aerodynamics, structures and systems

Other than spoilers, where are speed brakes located?

  • On the wing
  • Under the Fuselage
  • Either side of the Fuselage
jaketkchow asking:

why

Module 13. Aircraft aerodynamics, structures and systems

If one FMS fails in a duel system

  • system operation will not be affected
  • FMS CDU on fail side goes blank
  • FMS display transfers automatically from serviceable computer
nairs asking:

dual system......first answer looks good ??????

Module 13. Aircraft aerodynamics, structures and systems

Alert Height is when

  • a decision of whether to land is made
  • an alert of the altitude of the aircraft is made
  • an alert of the ground proximity is made
Tarvin asking:

There are two same questions and two different answers. In this case the correct answer is an alert of the altitude of the aircraft is made. Other case correct answer is a decision of whether to land is made.
So what is the right answer then?

Module 1. Mathematics

The specific torque loading for a bolt is 50 lbs.ins but an extension of 2 is needed to reach the bolt in addition to the 8 torque wrench. What will the actual reading?

  • 40 lb.ins.
  • 54 lb.ins.
  • 60 lb.ins.
ashish.dwivedi4 asking:

how??

Module 13. Aircraft aerodynamics, structures and systems

A triplex system looses one channel, the system is now,

  • fail passive
  • fail operational
  • fail redundant
Jordi asking:

shouldnt this be fail operational? it still has 2 channels

Module 13. Aircraft aerodynamics, structures and systems

An auto land system displays Land 2 another failure will make the system

  • operational
  • passive
  • simplex
Gibbo280490 asking:

Why would this not be simplex if it was origionally Cat 2? i thought a Cat 3 failure makes is Passive?

Module 13. Aircraft aerodynamics, structures and systems

When can the FMS be engaged with the autothrottle

  • only with the Flight Director selected
  • With either the Flight Director or the Digital Control System (DFCS) engaged
  • only after take off
Jordi asking:

I think this should have another option saying "before take off" because i have this as the correct answer

Module 13. Aircraft aerodynamics, structures and systems

in a CMC aircraft, flight deck indications and warnings are managed and provided by

  • the central warning computer (CWC)
  • the electronic interface units (EIU)
  • the engine indicatig and crew alert system (EICAS)
Gibbo280490 asking:

Would not be EICAS? 'Flight Deck Indications' ??
