which of the following are typical AP engaged modes during the cruise phase?

• Roll : LNAV

  Pitch : V/S

• Roll : TOGA

  Pitch : TOGA

• Roll : LNAV

  Pitch : VNAV

• Roll : LOC

  Pitch : G/S

The result of performing the first intergration to the output from the East/West acceleration of an INS when engaged in NAV mode is

• Aircraft’s longitude

• change in longitude

• velocity along the local parallel of latitude

• departure

with TCAS II , when a corrective resolution is generated

• the IAS must be modified without delay

• the heading must be modified without delay

• the vertical spped must be modified without delay

• no action is required

The measurement of SAT directly is not possible for Aircraft traveling fast because

• The airlaw causes too much cooling of the sensing probe

• the effects of adiabatic compression and frictional heating

• the boundary layer around the aircraft gets very turbulent

• most temperature sensors have a low Kr

In an autopilot system, the flight path modes are

1. Pitch attitude hold

2. IAS and Mach number hold

3. Attitude hold

4. Glude slope intercept and track

the combination regrouping all the correct statements is :

• 3

• 2,3,4

• 4

• 1,2,3,4

The aural alert(s) associated with the mode 2 of the GPWS is (are) :

1. ‘TERRAIN’

2. ‘SINKRATE’

3. ‘TOO LOW TERRAIN’

4. ‘PULL UP’

• 1,4

• 3

• 3,4

• 2,4

when flying level in the cruise the __ holds altitude and the __ holds the speed

• autothrottle , autothrottle

• autopilot, autothrottle

• autopilot, autopilot

• autothrottle, autopilot

the rigidity of a gyro is improved by

• increasing the RPM and concentrating the mass on the periphery of the rotor

• decreasing the RPM and concentrating the mass on the periphery of the rotor

• decreasing the RPM and concentrating the mass at the hub of the rotor

• increasing the RPM and concentrating the mass at the hub of the rotor

at high latitude, the magnetic compass becomes unreliable because

• the magnetic pole is oscillating

• the variation is changing too fast

• the magnetic field is too strong

• the directive force is too week

which of the following describes magnetic variation?

• It is because by the difference in position of the geographical North Pole and the magnetic North Pole

• it varies inversely with aircraft’s bank angle

• It caused by the inclination of the Earth’s magnetic field lines

• It varies proportionally with aircraft’s bank angel
