EFI

18
Q

In which mode(s) can radar returns be displayed on the HSI?

A

Map

Expanded ILS

19
Q

When can the flight director command bars be displayed on the ADI?

A

When the associated FD switch is ON and the system is supplying valid commands

20
Q

What will you see if ILS is tuned but a signal is not yet being received?

A

ILS localiser and glide slope scales will be shown without their pointers

21
Q

What is the source of magnetic heading?

A

Inertial reference system

22
Q

The VOR pointer has disappeared, what does this indicate?

A

The VOR is out of range

23
Q

What is indicated by the IRU ON DC lights momentarily illuminating during pre-flight alignment?

A

The IRU is testing the power from the main aeroplane battery

24
Q

During the normal IRS alignment, when does ALIGN light extinguish?

A

When the IRS enters NAV mode

25
Q

With any IRS ALIGN lights illuminated, are there any restrictions on moving the aeroplane?

A

Yes, aeroplane should not be moved

26
Q

What inputs are required by the IRS system before it can enter the NAV mode from the ALIGN mode?

A

Aeroplane latitude and longitude

27
Q

Which ILS information is displayed on the ADIs when an ILS frequency is not selected?

A

Neither the ILS scales nor the ILS pointers are displayed

28
Q
