Hi drodge_tondel,

[Edited from my original reply.
My apologies, I just realized that you're in Europe which would be why you might not be aware of the publication that I'm referencing below. It is so easy to overlook that this is an international forum.]

Please go back and review a copy of the U.S. Aeronautical Information Manual. It is an important information source for aviation and I typically quiz my flight students on it during training. It is amazing how much information is included in this publication.

You should be able to purchase one from A.O.P.A. (Aircraft Owner's & Pilot's Association) and further information may be found at www.aopa.org/safetycenter. Their phone # is 1-800-638-3101. They also have an international organization.

The book is convienently combined with the Federal Aviation regulations as a bonus. With reference to your question about the ground to air signals, please turn to section 6-2-7 on page #763 of the 2006 edition.

I would encourage all pilots to join A.O.P.A. for many reasons, not the least of which is that Doug has worked with them and presented seminars at some of their events.

Regards,
