Does anyone know the redline IAS for the Nimbus 4 at 45000 and 55000 feet? Does ballast make a difference?



Thanks

What are you looking to do here? The IAS is always the IAS, but the Va is TAS. I assume you are trying to see how fast you can fly IAS for a TAS equal to Va.

If you can give me the Va number, I will assume standard temperature for FL450 and FL550, then using my handy E6B I can figure the IAS.
