Yes, that's what you said but it is still not correct. 120 kts. is the specified Vne for Light Sport aircraft. See 14 CFR 1.1.

On the other hand, the POH for the ASK-21 and for the DG500 both indicate that the Vne is rather like a TAS, so the Vne CAS decreases with altitude. The 120 kts. Vne limit for Light Sport Aircraft (14 CFR 1.1) is a CAS.

It's all rather ridiculous.

The normal cruising speed for gliders is 60 - 80 knots. Even if you have a 160 knot Vne, you very rarely go over 100 knots. The Vne is there mostly for safe recovery from upsets.

Penalizing pilots for buying a safer, stronger aircraft is crazy.
