My son was asked “why” Va reduces with reducing weight in his RPL test, he couldn’t explain why. He knew it was 111 at max weight and 88 at min weight.
He was asked a lot of pre flight questions on the usual stuff from the RPL test form and got nearly all of it correct over 1 1/2 hours but he was told he needed to give 100% correct answers to the ground questions before the flight….so because of that he failed and didn’t leave the ground…..
An RPL TEST for goodness sake, not an ATPL test..
Go figure.
