Answer this.......

This is my first posting on tech log and I am hoping someone can answer this.


In simple terms how do the calibrating aircraft calibrate ILS, MLS, DVOR, NDB, DF and TACAN.
Sensible answers please as this is in relation for a job interview.

Here's a page with a pretty picture, but not much information, from a company that makes the equipment they have on board the testing aircraft.

From the sound of it they compare the received signals to where they should be, based on INS.

A ground crew accurately measures the survey aircraft's position while the a/c flies a series of manouvres for the aid eg for an ILS something along the lines of:

1. G/s & Loc centred
2. G/s full scale up, Loc full scale left
etc etc etc

I understand the survey a/c has rather more accurate receivers than usual.

Some of the calibration can also involve receivers placed around the navaid transmitter.

Can't remember anymore about it... http://www.pprune.org/ubb/NonCGI/redface.gif
