Has Kerbin's atmosphere been changed with 0.21?

not sure if anyone said thiss, but it seems air intakes now measure air in by both number of intakes AND speed. At slow speed the ram air intakes make almost no air..... if found out the hard way. you gotta keep speed up for them to work.

Here are some more interesting test results of various B9 intakes.

To eliminate as many variables as possible all test where done with the same plane with three intakes for one turbo jet engine and a continues climb of 30 degrees.

Widebody tested under the same conditions but with one intake and two turbo jets.

First number is the altitude where the intake air started to decline. Second number is at full throttle flame-out.

* Widebody starts loosing air ever so slightly immediately after take-off. Altitude mentioned is where intake starts to rapidly decline.

As you can see all B9 intakes in this test perform equal pre and post update. All except the RNM and Wide body.

Edit: Widebody intake added.

Intake air was always speed-dependent. The most significant change to stock intakes for 0.21 that I've been able to see is that the radial intake mass is now 10x lower.
