SWP in the UK is partly a misnomer. SQUEP pilots (suitably qualified and experienced persons) know that SWP is a construct which is drilled into anyone who operates machinery over here: (Buses, cars, lawn mowers, planes, boats, helicopters). F = MA.
If you don't have sufficent F in your engine(s) to equal MA, you will crash! Simples. Basic law of physics. There is no need to exagerate or obfuscate over it.
VRS, I would suspect is more akin to being discussed in aerodynamics/flying manuals/teaching aids, not a CAP from the regulator.
TC is leaving the building.........................shall I switch the lights off now. Are we all done?
