Just started with another airline and have a question on their acceleration altitude.
Normally company single engine acceleration altitude at 1000'agl unless
1. TOW > 138 tonnes. I guess this is for the 5 minute limit. OK so far.
2. If the T/O performace page says the minimum acceleration altitude is 800' (obstacles) then that is what WILL be used.
It's my understanding that if it isn't mentioned then the minimum accelleration altitude is 400'agl where the 3rd segment starts. If there are obstacles present why lower the acceleration altitude from 1000'. 800 is a minimum but not gospel surely.
One argument given to me is that the obstacle may be further on down at (say) 1200'. This doesn't sound right to me.
It's been a long time since I've done Perf A. So if someone can suggest some good arguments I'd appreciate it.
cheers n beers
