Default Knots to You....

I love it AJ...."When I have to run from a bad date, I get in my 200 mph+ airplane and leave the state!"

Now I know how all you speed demons like to use mph goes the numbers are bigger, but hey, if that's all you want, why not post in kph? I had a professor back in college (Senior Design, Aeronautical Engineering) that would not even accept a paper or report if all the units weren't in Knots...."That's the units we use in aviation kids, like it or 'knot' !"

Hmm....I need to keep that camera charged and along - got some long trips coming up, and maybe I can catch a wind....

Yah but you have to stay 2000 agl over national park airspace so you still can't get a neg MSL indication. I've considered it before and don't think there is anywhere to get a neg MSL???

Am I right about the 2000agl even??

Yep:

Pilots are requested to maintain a minimum altitude of 2,000 feet above the surface of the following: National Parks, Monuments, Seashores, Lakeshores, Recreation Areas and Scenic Riverways administered by the National Park Service, National Wildlife Refuges, Big Game Refuges, Game Ranges and Wildlife Ranges administered by the U.S. Fish and Wildlife Service, and Wilderness and Primitive areas administered by the U.S. Forest Service.

NOTE-
FAA Advisory Circular AC 91-36, Visual Flight Rules (VFR) Flight Near Noise-Sensitive Areas, defines the surface of a national park area (including parks, forests, primitive areas, wilderness areas, recreational areas, national seashores, national monuments, national lakeshores, and national wildlife refuge and range areas) as: the highest terrain within 2,000 feet laterally of the route of flight, or the upper-most rim of a canyon or valley.


The above is clearly depicted on all US sectionals.

If you were sitting at sea level and the temp was below 59 degrees f and/or the barometric pressure was > 29.92, you would get negative Density Altitude.

In the same situation, if the barometric pressure was > 29.92, you would get a negative Pressure Altitude.

You would physically have to be below sea level to get a negative MSL with the altimeter set correctly.

Is my thinking flawed?

A low pass should get you -180 or so.

I see what's happening here. Nobody could beat 252 knots (290 mph) groundspeed, so the conversation shifted to density altitude. What a copout...

C'mon, Kahuna -- I know you've seen faster than 252 knots GS!

And Rocket guys, I know you don't fly your airplanes more than about twice a year because of how expensive they are to operate, but c'mon, I know you can beat 252 knots GS!

Muuaahahahaha.

Just a little hopp from PHX to 5T6 (Santa Teresa, NM). Felt like we were "Coming Down The Shute" @ Reno Air Races. The Pic was from the hotel room when Lovey was reviewing our flight. I told her, "Take a photo, that ones a keeper!" Don't know if we can duplicate it for LOE '07 but, we're gonna try. 282.6 KTS

Ah, now see, you should have stipulated more stringent requirements. Anyone who's got a High altitude to low altitude descent can come up with some pretty spectacular speeds (staying away from VNE obviously). But I think this needs to be refined....

How about 200kts of GS or better in *cruise level*. I'm sure I could dig up a few of those, but I suspect that would be cheating... On a flight from ATL to ORL at 15000, with an indicated of 145, a TAS of 190, it doesn't take much of a tailwind to get ahead of 200kts in GS in level flight...

Anyway, I think the rules need to be defined as above.... 200kts or better in a descent just simply isn't fair...
