I destoyed a B737!!!!

[UnAnswerd]

I don't understand this. Microsoft flight simulator lists the 737 as having a cruise-speed of 477kts. However, everytime I go above even 350KIAS, I get a warning on the screen that says "overspeed". Shortly after that, I get a sign that says "aircraft overstressed". Then it makes a sound like it is blowing up in mid-air and it's game over. I'm not joking around here. Does anyone know why it's doing this? Flaps and landing-gear are retracted...

yeah you wont see 477kts Indicated Airspeed...see if it has a TAS readout...or better yet, what is the %Mach (ex: .85)

 

[urflyingme?!]

You might be at too low an altitude. Max speed in an aircraft like the 737 is determined by many fcators, and displayed by a red and white "barber pole" on the airpseed gage. It is similiar to the indicator, only this "arm" of the gage is red and white striped, more like a cnady cane than a barber pole, but I digress. Try going up to FL350, you'll get up to speed i would imagine.

A quote from my groundschool instructor abut the CRJ, which has a "clacker" to warn of overspd, "If you're not a clackin, you're a slackin!"

So that's what that noise was! Thanks everyone for the information. Video games are sure a fun way to kill yourself.

You can go to realism settings and turn that off you you don't want to overstress.

kinda like pullin' the breaker, huh?

IAS, CAS, TAS, Vmo, Mmo: these terms come to mind. At altitude in the TBM, for example, usually about 180 KIAS, give or take. But TAS about 280, give or take. (Vmo, as I recall, is around 260 kIAS, maybe less). Not unusual to see 100-110k differential between IAS and TAS at altitude in that airplane. Go higher in an aircraft capable of it and you'll see bigger differentials. The "I'm not joking around here" was classic. Neither is the airframe should it begin to fail. (Although I was told once by a knowledgeable source that the Vmo on one bizjet type was influenced at least in some small part by windshield integrity considerations.)

HUH?????!!!!??????

Its true airspeed, the B737 is not capable of 477 indicated. The NG can do 340 IAS and mach .82. In standard conditions at sea level (assuming zero instrument and position error) IAS=TAS. So 250 KIAS is the same as 250 KTAS. AT 41000 in standard conditions the density will be one quarter of that at sea level therefore your TAS will be twice your IAS. ie at 41000 250 KIAS=500KTAS.

 

[Singlecoil]

A good rule of thumb is 2% per thousand feet to convert IAS to TAS.

Meaning at 25,000 feet, your TAS is 50% higher than your IAS.

Or 300 kts indicated would be 450 kts true.

(25x2%=50%) 50%x300=150 150+300=450

At 41,000 feet, TAS is about 82% higher than IAS.

Or 250 kts indicated would be 455 kts true.

(41x2%=82%) 82%x250=205 205+250=455

I was going to say that I think the aispeed indicator usually indicates about 250 at 390-410 and mach .80. Thanks for the actual math!
