Why gyro-tyro?

I am going to learn to fly autogyros and I am going to blog about it here. A tyro is a beginner or novice. 

Tyro is a word which has its origin in the Latin for a recruit or young soldier. However, I first heard the word when studying for my Radio Telephony licence for flying microlights. Tyro was used as a prefix at the start of radio transmissions between student pilots and air traffic control, though I gather that it has since been changed to "student", as I suppose most people simply don't know what tyro means.

I will stick with tyro. I like words, and of course I like the fact that it rhymes with Gyro.
