Chimbu....I have never done the emergency descent in anger,but had to display the manouver during renewals. The descent is carried out with knees locked whilst standing on the rudder pedals,looking way up the top of the windscreen at the horizon & straight ahead at the top of trees.
The way it was taught in Talair was 80kts/flaps 20/full reverse...the resultant deck angle was not far off vertical - you tracked VERY slowly over the ground.
I have never done one 'in anger' ...only ever with a silly grin.
There was another version with flaps 20/flight idle and a tight turn - that usually resulted in a silly grin too.
