Hello all,
Sorry if I didn’t make myself clear…I never plan on taxiing around with transponder on. I was asking ‘why bother to change it from off to standby for taxi'. I guess Final 3 Greens point is very valid regarding it offers a method of double checking the transponder is not squawking by setting to standby…
Keef: That is interesting. Thermionic valves seems a very backward technology to be using though, very prone to damage from vibrations. But it would explain the delay. Bizarre.
Thanks for the replies,
Tom.
