Slowing down from supersonic

[amollen 0]

I've been trying to slow down the Concorde after a supersonic flight according to "the book", this is what I do:- at the Decel point, pull back the power to 18 degrees, maintaining altitude (usually FL 600)- once the plane hits 350 kts IAS, I press the IAS HOLD on the autopilot (not the autothrottle) which will cause the plane to start descending at about 2000ft/min maintaining around 350 kts- once going Mach 1.5 I further reduce power to 32 degrees as the manual describes- I level off at "normal airliner" altitude and wait until I am subsonic, after which I continue a more normal descent.The problem is, when following the manual, it takes forever to slow to Mach 1.5 so I have to cut power sooner if I don't want to overshoot my destination. It's no big deal but I like things to be as realistic as possible, so I am just wondering if I am doing something wrong or if I should just ignore this little discrepency.

If you're following the by-the-book TLA's, a good rule of thumb used in the R/W is to take the digit after the decimal on the Mach Meter, multiply by 10 and this is a good indicator to how many nautical miles you'll take to slow to Mach 1. So M1.5 = 50nmCheers,Paulhttp://www.strontiumdog.plus.com/conc_capt_ba.jpgConcorde Training Captainwww.BAVirtual.co.uk
