A space gyro can also be referred to as:

A Rate gyro

A Free gyro

A Tied gyro

An Earth gyro

The countermeasure to compensate apparent wander due to earth rate by creating a precession rate against the earth rate error is an intentional...

unbalance on the vertical gimbal

friction in the bearings of the vertical gimbal

friction in the bearings of the horizontal gimbal

unbalance on the horizontal gimbal

The altimeter usually has a bimetallic temperature compensation. Why does a temperature error still remain? Because the bimetallic compensator...

does not compensate for outside air temperature effect on the pressure/altitude relation

only senses the outside air temperature, not the cockpit temperature

does not vary with the static pressure and the required compensation does

does not have sufficient capacity

What is an operational difference between the turn coordinator and the turn and slip indicator?

The turn coordinator is always electric; the turn and slip indicator is always vacuum-driven

The turn coordinator indicates bank angle only; the turn and slip indicator indicates rate of turn and co-ordination

The turn coordinator is sensitive to roll rate and turn rate and will therefore indicate when the turn is initiated

The turn coordinator indicates angle of bank; the turn-and-slip indicator indicates turn rate in co-ordinated flight

Which of the following cause Real Wander?

The rotation of the Earth

Mass imbalance and bearing friction

Apparent precession due to the Coriolis effect

Movement of the aeroplane over the Earth

Among the flight control instruments, the artificial horizon plays an essential part. It uses a gyroscope with...

One degree of freedom, whose horizontal axis is maintained in a horizontal plane by an automatic erecting system

Two degrees of freedom, whose horizontal axis corresponding to a reference direction is maintained in a horizontal plane by an automatic erecting system

Two degrees of freedom, whose axis is oriented and continuously maintained to local vertical by an automatic erecting system

One degree of freedom, whose vertical axis oriented in the direction of the real vertical to the location is maintained in this direction by an automatic erecting system

Among the flight control instruments, the artificial horizon plays an essential part. It uses a gyroscope with...

One degree of freedom, whose horizontal axis is maintained in a horizontal plane by an automatic erecting system

Two degrees of freedom, whose horizontal axis corresponding to a reference direction is maintained in a horizontal plane by an automatic erecting system

Two degrees of freedom, whose axis is oriented and continuously maintained to local vertical by an automatic erecting system

One degree of freedom, whose vertical axis oriented in the direction of the real vertical to the location is maintained in this direction by an automatic erecting system

When turning onto a northerly heading the rose of a magnetic compass tends to undershoot; when turning onto a southerly heading it tends to overshoot. Which statements are correct?1) The compass indications are less reliable in the northern hemisphere than in the southern hemisphere.2) These compass oscillations following a lateral gust are not identical if the aircraft is heading north or south.3) This behaviour is due to the mechanical construction of the compass.4) This behaviour is a symptom of a badly swung compass.

small left bank angle and nose up attitude

right descending turn

Both the ADI and the HSI

The Attitude Director Indicator (ADI)

The principle of operation of the rate of turn indicator is based on...

precession

rigidity

rigidity and precession

centrifugal force

Which of the following is correct when describing a Turn Co-ordinator?

It indicates the angle of bank and turn rate

It is suitable for a stand-by artificial horizon

It displays turn and pitch for rate one turn only

It responds to rolling for a bank angle as well as turn

Electrical artificial horizons correct for topple in pitch by:

pitch gravity switches and pitch torquers mounted around the longitudinal axis

pitch gravity switches and pitch torquers mounted around the lateral axis

A pendulous mass

2, 4

Which part is the essential difference between a servo altimeter and a normal pressure altimeter?

The indicator

The linkage from pressure sensor to indicator

The pressure sensor

The subscale mechanism

The gimbal error of the directional gyro (DG) is due to the effect of...

too slow precession on the horizontal gimbal ring

an apparent weight and an apparent vertical

the aeroplane's track over the earth

a bank or pitch attitude of the aeroplane

You are in-flight to a destination with no alternate aerodrome. En-route, in case of inflight replanning, which time frame is required for the weather forecast to be above applicable minimum?

1 hour before to 1 hour after the ETA

3 hours before to 3 hours after the ETA

at the ETA

2 hours before to 2 hours after the ETA
