TBM 900 Ground Speed

Hi all,

I was flying at my cruise alt. and I noticed that with a 26kt headwind I had a 207kt Ias and a GS of 257 kts. flying with a headwind I shouldn't have GS faster than IAS.

Hi cessna_man,

this actually seems to be correct.

I did a quick check on my trusted old calculator: assuming a OAT of -20°C (unluckily it's not showing on the screenshot) it shows TAS of ~275kt at an IAS of 207

Don't forget that at higher altitudes there is quite a significant difference between IAS and TAS.

Cheers

Hi okidokki, Thanks for the reply. I forgot about TAS altitude, ect.  Makes sense.

Thanks again
