INS questions
 

- what flight instruments take information from the INS ?

Thanks ahead.

I suppose it would depend on the aircraft in question, but the 747(Classic) INS's feed data to....

Weather Radar
Autopilot/Autothrottle
Yaw Damper
Magnetic Heading Reference System
LRCU's
Overrotation Warning Computer
EGPWS

The ADI's get their pitch/roll date from the INS's.
The HSI's get their compass info from the IRS's via the Mag Heading Ref systems. XTK, TK, TKE, DA, Distance+Time is also provided to the HSI's by the INS's.
INS pitch and roll data is transmitted to the Enhanced GPWS (where fitted).
Weather Radar antenna stabilization requires INS data.

Rgds.
