Swiss PPL for rotor head

[javier]

Dear friends,

I have a couple of friends that just bought a new Helicopter. They need to get their flight license first for flying it.

They are going to take it on Swiss. but i am going to teach them some theory first on Spain.

Can anyone help me to find out the requirements to get PPl on Swiss.? which books are normally used in English?


thanks for your help
