Mode C response is

• 21microseconds
• 12 microseconds
• 8 microseconds

The autothrottle controls the aircraft

• vertically
• laterally
• both later ally and vertically

A radar antenna is facing left. On ground test, if you move the vertical gyro to simulate a right bank, the antenna

• will move up
• will move down
• will not move

with no.1 h.f. system transmitting the interlock circuit

• allows no.2 h.f. to receive only
• allows no.2 h.f. to transmit and receive
• does not allow no.2 to transmit or receive

High and low signal to voter are

• average
• removed
• added

The VSWR of a VHF system with a forward power of 100W and a reflected power of 4W will be

• 1.5:1
• 2:1
• 2.5:1

What does an INS calculate on power up?

• Last Known Longitude
• Last Known Latitude
• Last Known Longitude and Latitude

When a compass is in the slave mode

• the azimuth gyro will wander uncompensated
• azimuth gyro will be corrected by long term monitoring of the flux valve
• the azimuth gyro is slaved to the annunciator or synchroniser circuit

In a starter generator which coil is used for starting?

• Shunt, series and compensating windings
• series compensating windings
• Shunt compensating windings

The Janus beam is for

• working out acceleration
• levelling the aerial
• to compensate for attitude changes
