Hey Chris,
I am not sure whether you are joking when you ask what an NDB is? If you are serious and you are also applying to pilot sponsorship schemes then I suggest you start to read round your chosen career a little.
I would estimate a high percentage of candidates applying to these schemes have a very good general knowledge of aircraft and systems. If you do not have some basic knowledge about such things it will not bode well in trying to demonstrate your enthusiasm for flying.
Just my opinion. Good luck with your application.
Cheers.
