I have been flying all my planes including my jets on the ham band for several years, and have never had a problem.
I do take my Icom scanner with me so that I can monitor the frequencies, both the 50 and 53Mhz ham, and 72Mhz band.
I use JR 10x with dual conversion receivers.
To study for the test you can get a study guide at Radio shack and within a week, you should be able to pass the test.
