You are at FL 370 at Mach .80. When ready for descent, start the nose down while slowly closing the throttles. Keep Mach .80 until you get into fatter air. Around FL 300 to FL 290 transition to IAS and continue descent at 290 KTS. You can change the speed to adjust the descent unless ATC has given you a speed. All the while you need to keep updating your descent profile to see how its going. If your numbers show you a bit low on the profile, add a little power and re-check the profile. If ATC assigns you a speed, as they often do - for instance a lot of times they will say "you are leading the pack, keep your best forward speed." No problem, just add power and get the speed to the barber pole if you want, but keep an eye on the profile since you will have to make some adjustments in the IVSI to stay on the profile. |
I can't believe it! Why the heck was I not thinking of the fact that at high altitude I use Mach and not KIAS! Doh. I feel like a complete dunce. It must be because of my current pain relief medicine! It is not allowing me to think straight. :( Hey! I gotta blame someone/something. ;) @Brian. All speeds were KIAS. Mark
