Hi!

I have a problem when start descend with my 737... i'm at cruise level 210 and the ATC tell me "...start descend to FL 150 and reduce speed 250"; i select 250 speed and 15000 then press LVL/CGH mode with speedbrakes deployed, but the descend start slowly with 100, 200 max feet/min; whern i approach to 250 knots, the ATC tell me "..please, expedite your descend !!!"; then i set 2500feet/minutes descend, but even with full drag, my speed up to 300kts (sic!).

Please, help me, before the air brakes catch fire :-))

Thanks

PS: i tried VNAV DES NOW without success...

What ATC are you using?

Okay, that's the problem, then.  Real ATC and most ATC programs know the basic concept of slow down or go down, and that planes have a very tough time doing both.  Normally, what happens is that you descend at your ECON speed (somewhere around 270-300ish knots - this is the speed on the VNAV DESC page), and then you level off just prior to the speed restriction and decelerate to meet that speed at the fix.

 

A more accurate instruction that ATC would give is:

"Descend and maintain FL150.  Reaching FL150, reduce speed 250 knots." (go down first, then slow down)

 

The tutorials explain this very well, so I suggest you do them.  It'll teach you anything and everything you need to know about the plane.  This plane behaves realistically, so you can't approach it like any other plane you've flown in FSX before.  You have to learn how to use it properly for it to behave properly.

 

Asking it to do what you've given an example of is not realistic, and it's not practical.

 

Again - have a look at the tutorials.  Fly both of them.  If you have flown both already, do them again and really concentrate on what it's teaching you.  This is a study sim.  It's going to require some learning.

Ok Kyle, i will do!

Thanks
