Always Something New

Just to show that FS can still surprise you

Nav,

VERY interesting reading.

Same thing happened to me once commin-outta-the-hole at Felts Field realworld in Spokane WA in a C172 fully loaded with temperature at 34C. After suckholin over the housetops, I learned about density altitude

I have to admit this is one of the few weather experiences I lack in FS, and I too have a penchant to make world round trips with a lot of different airplanes (I'm still in the middle of my last, to complete using mainly prop planes from the 30ies to the late 50ies).

Microbursts, I had a lot. Windshears, at will. Killer stalls, all too many (especially on the Realair SF260 2005 in tight turns). The kind of experience you did is something I never had, even over the Bermuda Triangle.

Seem strange though, those values of temperature and pressure you were having. And really can't help but wonder if it was a glitch of the real weather.

Well i have to say my first reaction would have been to dive to thicker air, where the engines would work.


as for the posibilty that happening in the real world happening, i guess maybe a reverse micro burst may be what it was  ???

Truly interesting.... I need to get out (in FS) more...

The sim is amazing. Great story !

But I have to wonder if the "true to life" reaction you had to the combined atmospheric conditions resided with the sim itself, or the programming of the add-on aircraft you were flying?

It's both. It's in the sim as far as realistic density altitude and how the engine reacts. It's in that Dove when it comes to how you could get caught like that. Here's the important part of the aircraft.cfg file:

turbocharged= 1
max_design_mp= 45.000
min_design_mp= 7.000
critical_altitude= 4400.000
emergency_boost_type= 0

It will give you good MP (atmosperic) well up to a good altitude. The big difference here, compared to most turbo-super-charged planes in the sim, is that the critical altitude is 4400 (as opposed to 18000)(in a plane whose critical altitude is 18000, you'd barely notice this "hole" .. unless for some reason you got that piston beast up to 30000). If you were well above 4400 when you ran into that "hole" in the air.. the MP would drop off drmatically (and your mixture would be WAY rich).

The only thing I find curious.. is that the temps were high. An engine running rich and at low MP would show "cold" EGT or CHT..

Thought of that, Falcon500, but a combination of a fondness for long over-ocean trips AND the fact that I did a bit of real-life gliding once upon a time have made me tend to be miserly with altitude.

I apply a rule to my RW flights - if I pile up I
