FSX-MS Speed issu with CS 777 and LevelD 767

[panam 0]

Good morning

after i had to re-install my FSX simulator I do face following issues with the LevelD 767 and CS 777  (no such an issue with QW 787 and PMDG aircrafts)

The indicated airspeed between knots  and mach does not correspond with increasing the altitude. E.G Flight level 31000 i have mach .83 but knots are showing 488

As it worked correct before new istallation i have no idea where the issue is. Any idear or any same issues.

I tried to get answer from CS-Support Forum but no answer

 

Any support to solve this issue would be very much appreciated

 

thanks

I don't understand!  How do you think the numbers should look?   When you increase altitude and flying at MACH, your KIAS will decrease.  It's ground speed that counts!

It's IAS that keeps you in the air . GS gets you there!

Not sure what you are referring too?

I would bet that 488 KIAS would keep you in the air!

The whole question doesn't have enough information. Altitude, Temperature etc. 488knts GS  or ias? 488ias is excessive high ias.

Not necessarily. Depending on upper level winds. IAS is everything.
