GaryGnu,
Your normal V1 wont be VMCG limited, but what happens when you make MEL or contaminated runway corrections to it?
TCAS Climb,
You have confused me, surely there is a difference in weight between the two runways? Why would you expect to have a V1 decrement on the shorter runway?
John, welcome back.
I guess that you are talking about the 727? I dont know about OZ certification rules, but my Boeing book states that under the FAA the 2 second rule did apply. A 1 sec time delay was added to (a) Brake application to thrust reduction on remaining engines (b) Thrust reduction on the remaining engines to speed brake action. A 3 sec time delay was used on B727-100 aircraft without and engine failure warning system.
Mutt.
