Q

On the EADI the localiser deviation pointer will reverse when aeroplanes track deviates more than 90 degrees from the selected ILS course, this is to insure that?

A

The localiser deviation pointer is usable during back course approaches and is also to insure that there is constant compatibility between the EADI and EHSI localiser deviation direction.

Q

Considering the EHSI, what is the SG(symbol generator) responsible for?

A

The symbol generator draws data from the aeroplane’s sensors and avionics equipment, processes and converts this data to provide the various analogue, digital and discreet signal interfaces between the aeroplane systems, the display units and the Mode Control Panel.

Q

Considering the PFD, the air data computer is responsible for?

A

The transmission of static and pitot pressures data to the PFD, static and dynamic pressure will be converted to electrical inputs which in turn are transmitted to the PFD.
