Autothrottle & TCAS

[ben123]

I have a couple of unrelated questions that I just can't find the answers to anywhere. If anyone out there could give us a hand with these I would really appreciate it, Cheers Ben

Q1) On take off with autothrottle engaged, should the autothrottle system speed detector fail then the AFCS system will annunciate a THR HOLD state :-

a) when the aircraft leaves the ground
b) at a computer calculated take off speed
c) at a specific radio altitude

Q1) If two TCAS equipped aircraft see each other as a threat and declare the same intent then :-

a) both aircraft turn left
b) the aircraft with the highest address reverses intent
c) the aircraft with the lowest address reverses intent

Q1) If two TCAS equipped aircraft see each other as a threat and declare the same intent then :-

The two TCAS equipped aircraft DO NOT TURN but either climb or descend. TCAS with command a "Climb", "Descend", or "Monitor Vertical Speed." The IVSI will have a red and/or green arc. You just adjust the rate of climb/descent to keep it out of the red.
