Expensive Gadget?
Hi there Leftsideview (student or captain?) No offense man but I strongly disagree on claiming TCAS as an expensive gadget. I think its a complete ridiculous statement considering worldwide airspaces are now RVSM active. It is in fact a mandatory ICAO requirement for aircrafts flying at those FLs.
I agree with Schumi - Red Baron. A320 tests in the 90's have proved it in the best fashion. Plus its not up to ICAO to decide on who or how many crew fly the aircraft. In fact there is a minimum crew number stated for legal operation. Check conventional Russian carriers (nothing against them) flying with 4-6 crews.
