Soooo, I was having my briefs removed after my initial on a new jet and the point about selection of TA only when taxiing and TA/RA when cleared to line up apparently did not please my good fellow as much as one would expect. Habitual from a number of years and when trying to find a specific reference in a number of publications and a few google searches couldn't pin an answer down. Many references to 1030mhz and other tech things but can anyone give me the exact reference (and why more to the point) we have TA only for taxi and TA/RA for go? The more I think about the logic, the more it bakes my noodle.
Cheers
It's a hangover from the olden days when arriving flights would get climb RAs based on things taxying around the aerodrome. It should not happen with current generation equipment.
