Aircraft overSpeed??

Does anyone know why i am getting the message "OVERSPEED" on any aircrafts in fs04, although the aircraft is capable of fliying more than the speed, when the overspeed message appears.
For example : 747-400 is capable of fliying at 565 or so its says
I am getting the message "overspeed" at 365 or so

I'm not really sure but I know that under 10000 ft the FA requires aircraft not to exceed 250 knots normally.
With the ATC permission you can co over 250 knots that is probably put there for military aircraft.

Hi,
It is true that the 747-400 can do 565 mph. It says you are overspeed on the speed dial because that is in KIAS. The best way is to judge the mach speed also given, as the mach number given in the aircraft details will be the same in the aircraft, so you don't need to change it. When the mach number reaches .85 I think it is, at 30000 feet you will probably be doing 560 mph.
Hope it helps 😀

Thank you all for your responses. Please post anymore helpful information.
I found this convertion on a web site !

1 knot = 1.1507794 mile/hour

IS there anyway to know the aircraft speed in mph using the gauges in the airplane? is ther a downloadable guage?

The overspeed alert is tied to Indicated airspeed. At altitude i.e. 30000'+ even though your airspeed indicator might be saying 300 kts. you are actually going closer to 470-480 kts true. Remmember, your airspeed indicator essentially measures aerodynamic pressure, not true airspeed. It also gives you an idea of how much stress you are putting on the airframe. That is the limiting factor in flight. If you are flying at 300kts ias. at 35000' you are actually putting less stress on the craft than if you were going 350 kts ias. at 5000'. The overspeed alarm is there to keep you from tearing the airplane apart. If you look at any aircraft manual, there is a set of V speeds, Vr, Vx, Vy, Vme, Vmc,that's for twins, Vle, Vfe, Vno, and last but not least, Vne, also denoted by the red line on the airspeed indicator itself. It stands for velocity never exceed. To go beyond that speed risks airframe breakup in flight. That is the primary killer in inadvertant VFR entry into IFR conditions. The pilot who has no IFR training gets into a cloud or worse, gets disoriented, loses control and pulls the plane apart in a dive they don't know they're in, or when they pop out of the cloud close to the ground and tries to pull out of it too fast.

I'm sure you meant that the other way around... 😉

Otherwise, it's back to ground school for me hehehe.

nope, he's right, looks like its back to skool for you. Reason being, the air is thinner up there than it is down here, so that equates to less stress on the airframe 😀

fire emblem master, you do also have to take in account of the fact that the higher you go, the greater the pressure difference in the surrounding atmosphere, therefore more air needs to be bled from the engines into the cabin to maintain the correct cabin pressure, therefre putting more stress on the aircraft the higher one goes.

Welcome to the forums Quamar! Fire emblem master has left the forum long time ago and please don't answer posts that are 4 years old! Cheers
