Overspeed warning explained.
These are general or approximate figures to make it easier to understand. For specific real world Overspeed spec, google it. :) or Check this resource
Civilian aircraft have structural and engine tolerance limits.
While it’s true they feasibly could reach extreme speeds, they shouldn’t.
350 Knots airspeed is NOT a definite or perfect indicator of forward momentum AKA MPH ground speed.
At 30,000 feet 300 Knots airspeed is NOT 300 MPH ground speed. It’s actually approximately 510+MPH or Mach .80-.82 (depending on environmental factors) which is a common airliner cruising speed and altitude.
Airspeed is about air flowing over the wing. As altitude increases, air density decreases, thus the displayed airspeed (IAS knots) diminishes, and cannot be considered relevant to the aircrafts true forward speed.
Watch under the HUD where you find GS (Ground Speed) or M (Mach speed) numbers.
If the M is over .87, you’re going dangerously fast.
At the same altitude 400 Knots would be (about) Mach 1.+ and if it were a real aircraft, control surfaces would freeze, the aircraft would vibrate violently, and possibly even disintegrate.
So before you freak out thinking the Overspeed warning is “unrealistic”, think about it, learn about it, and slow down. It’s actually very realistic, and since Infinite Flight is a simulator, it’s a normal simulated function based on real world aviation.
So no, you should not have the throttle at or near max thrust. You wouldn’t get on the freeway pedal to the medal, riding the max red line to cruise to your destination?
Pass it on, share this, and help your fellow virtual pilots fly safe and understand why.
PS- Nobody is perfect, so if the Overspeed warning seems wrong, please let us know and send the actual VMO/MMO specs for the aircraft in question.
