My CPL training was;
Throttle Closed (establish best glide speed/attitude)
Mixture ICO
Fuel off
Check fuel pump off
Mags off
Gear down
Mayday call
Electrics off
Check if fire is out (most fires will be out by now)
--if not-- Emergency decent
Steep dive at max gear extended speed with 45 - 60 angle of bank leaving just enough height to slow and land. - Chances are it won't put the fire out but it will get you down quickly and give you a good 360 degree lookout for a suitable landing site.
Have never practiced the drill in an A/C with fixed gear but would probably opt for Vno with a steep gliding turn.
As for Vfe - worth considering on an aircraft with mechanical flaps. I like the option of deploying/retracting flaps to nail that field, so not much use in a cessna - I was taught to turn the electrics off early unless positive the fire is not electrical.
I personaly probably wouldn't opt for any structural limiting speed such as Vne with a fire and thus possible weak structure- it would also take a while to bleed that speed off before touchdown leading to a possible close encouter with a hedge!
I think what I would actually do would depent on the circumstances, situation and aircraft. This topic has definatley given me a few more ideas. Maybe a Vfe dive with 60 AoB?!
Any ideas on the fire drill when IMC over high gound??
