40,000 in a nosedive

[effte]

575 or thereabouts.

 

The speed bar shows TAS though, which increases by about two percent over IAS for every thousand feet above sea level. 926 km/h at 880 m ASL would be around 535 mph IAS, assuming standard atmosphere conditions.

 

Edit: Correction: It actually seems to be geometrical speed, i e the absolute speed in an earth-fixed reference frame. I e TAS affected by wind but not GS as such, as it will e g indicate the true velocity in a vertical dive.

Left out the units on the IAS.

Thank you for this. This makes it very clear.

 

 

In other words, the sensitivity of the libelle (the glass tube with the ball) increases with reduced G loading!
