Are there any websites for tips on flying in the USA? Just so I can catch up with their way of doing things.
Depends. What do you know already? Have you flown there before? Have you had any formal training on their regulations?
The starting point would be to read 14 CFR Part 91
(here) . You'll also find links on that page to the rules on airspace and airman cerification etc. but Part 91 contains most of what you need to know for basic VFR flights. It's not quite as 'wordy' as our ANO or rules of the air, but if it's not clear there are other websites out there with 'plain English' versions of the FAR's.
Other good websites (which have probably been listed many times before) are:
www.avweb.com - a commerical site offering news and articles about GA in the USA
www.airnav.com - contains airfield, runway and frequency details and links to FBO's for every public use airport in the US.
www.pilotage.com - details of airports in the LA basin/San diego area including charts, arial photos, links to FBO's and other businesses.
These are just the first three I thought of that may be of use to you. There must be thousands of others. AVWEB alone has enough interesting articles, reviews and quizzes to keep you busy for several weeks of solid internet access (I know, I used to work nights alone
)
