Surely the 777 does not have those steam-driven transponders with rotary code select knobs. Surely it would be fitted with the newer push-button code entry controllers that don’t change the transmitted code until the fourth number in the code is entered
Quite right Creamie.
Also in some jets I fly with the rotary code selector knobs, as soon as the knob is turned to change the code the TCAS/Transponder goes to standby mode until all digits are selected and set for something like 3 seconds, not sure of exact timing.
As far as this thread goes...Never have so many understood so little but written so much about it!
