JW411 and Mutt....
Re:- Geneva runway 23. A common destination for us, we use Jeppesen charts and the Boeing BLT, and these details refer to the BBJ.
From memory, the emergency procedure is to climb straight ahead and at 4DME GVA commence a left turn on to a HDG of 110 (15 degree bank angle)and then when we cross the 195 Radial GVA turn to SPR and take up the hold climbing FL070.
Which if nothing else serve to illustrate that there is more than one way of "skinning the cat" in terms of solving performance problems.
