TA/RA > ALT ON : ATC Question
Hi ATC
Please can you confirm what difference you see on your screen if an aircraft has transponder with ALT ON or TA/RA ? Am I correct in thinking that ALT ON the TA/RA is suppressed but modes A,C,S are all operating the same in both modes ?
We now have ALT ON on our checklists from taxi to runway and runway to stand.
Thanks.
