I saw a program on the Discovery channel where they featured 3 hour long documentrys on a Air Canada flight from Toronto to Frankfurt.As the plane is cleared fro take off the 1st officer says "3000,TARA,landings lights on,before takeoff checklist complete,EPR"
I would like to know what does 3000 TARA mean.

TA/RA refers to TCAS system and transponder and means Traffic Advisory and Resolution Advisory. It's a transponder mode which activates the TCAS for the flight. 3000 can mean the transponder code, but I think it also might be the initial climb altitude (3000 feet) where the aircraft has been cleared by the ATC.

On the B747-400 Takeoff checklist the response to Transponder is TA/RA.

This mode governs the TCAS advisories, TA = Traffic Advisory and RA= Resolution Advisory.

I dont know if that what Air Canada uses the term for, but its a good guess!

Oops M80, you got there before me, so much for the time lag between reading a message and writing the reply.
