Don't you guys and gals have approval to use your ATM for the advance uses as listed in MATS pt1?
When approved by the CAA, the ATM may also be used to:
a) following identification, validate SSR codes of departing aircraft and verify associated Mode C read-outs;
I know that asking the altitiude is part of verifying Mode C.
Just wondering t'is all!
