Slow dropping the airspeed in 737

Recommended Posts

Guest vrapp

When descending 737-900, I have a hard time dropping the airspeed. Even though the rate of descend is very modest (800 fpm for example) and the thrust is at the minimum, the aircraft is dropping the speed very slowly, about 5 times slower than fs stock 737. Once the flaps are extended, the speed begins to drop down much faster, but going from, say, 280 to 240 kts without constantly applied airbrake takes several minutes. Is this by design?thanks,Vadim Rapp

she's a toughie alright, I have this problem too, I think it's by design, just practice is the only solution I think....makes you wonder how these low-cost airline pilots do speed descents though eh?

I've noticed that when a fix has both altitude and speed constraint, the VNAV PTH descends to the altitude before the fix and lets the airspeed bleed off holding altitude. I use the same technique when not using VNAV. If I'm trying to get down, the gear can be extended below 270 KIAS.

The B739 needs a careful descent planning. When planning your descent remember one thing: The higher your indicated airspeed is the higher your rate of descent can be.Regards,Markus
