Diversion from SID/STAR questions

Hi everyone,

A couple of questions about SID/STARs:

If you're on a SID which has certain points with speed restrictions, and ATC clears you to climb to a higher altitude than the initial stop...

I'm familiar with that document, and it doesn't explain what I'm asking. It just states that this is the case, but not why this is the case.

Using flex temperature on contaminated runways

Hi,

A simple question: why is using flex temperature on contaminated runways not allowed?
Using flex temperature still uses the Vmcg for the full rated thrust, so it's not that you would lose...

GPS: what does a satellite send out?

Hello,

A GPS satellite sends out ephemeris and almanac data, on that subjects all sources I've read agree.

VOR and variation

Hello,

In a book I've read the following about an RMI:
If the aircraft's variation is different from the VOR station's variation, the indication of the relative bearing is incorrect, but the QDM...

Okay here are two theories:

Why the drag decreases with wing sweep in subsonic speeds below M2.1:
The part of the wing behind the mach cone 'knows' the air is coming, so the airflow can...

Then, why is the drag less below M2.1? Why suddenly, above M2.1, the drag gets higher for a higher swept-back wing?


I assume every other aspect of the wing remains the same. According to the...
