The Vne mark on the ASI or on the glider's placard is specified as an IAS so you can easily compare it with the ASI reading.
The difference is that while most limits (Vs0, Va, Vm, ...) have a constant indicated value (and a variable true speed), Vne
MAY be more constant as a true value but it actually is a bit more complicated.
