i’ll rephrase my response for clarification. You can experience ‘high speed buffet’ in any high speed capable aircraft at a high IAS. It’s called......wait for it......high speed buffet (compressibility effects) and you can experience ‘low speed buffet’ in any aircraft. That one is low speed buffet (classic critical angle exceedance). In my work they are referred to as just that, low and high speed buffet. They are both a stall, brought on by different aerodynamics but both produce loss of lift across the wing. I should have specified the difference earlier. I was just unsure as people were barking on about not be8ng able to have a LOC due to a ‘stall’ at a relative high speed. It only takes a few degrees of attitude applied too abruptly and bang your in it. I never mentioned EAS v IAS at any altitude. Rant over.
