Question: Squitter and Mode 'S' usage?
Paris CDG uses the "Squitter" tracking secondary radar which uses an aeroplane's Mode S squawk to track its movements on the ground.
When are you supposed to have Mode S switched on? Is it chock to chock (for example on pushback), or only when taxiing? And does it matter if the xpdr is set to TA or TA/RA (with RA obviously inhibited on the ground!)
Also does anybody know if squitter is going into service at AMS Schiphol any time soon?
