Hello,

I have flow many IFR flight plans and have been wondering when ATC tells you to descend to say 13,000 feet and then most of the time to 2,000 feet sometimes when I then get to 2,000 I am there for a while becasue when I was on a aircraft it seemed as though we are constantly descending at the end and here (with my problem) I stay at this altitude (2,000) feet fow a few miles. 

Is there something I can download for this problem or is it just a default with M$ 2002?

The reason you stay at 2000 ft on a fixed heading on an IFR approach is so you can get established on the localizer and glideslope of the ILS system.

The heading is at approx 30deg to the rwy heading and the alt is so you can intercept the glideslope from below about 4 or 5 miles before the outer marker.
