My tips:
- Don't put the aircraft keys in your jeans pocket as you walk to the aircraft to fly it.

- Don't plan to fly the day after a PPRuNe bash!!
- Know the length of the tip of your thumb in nm on a half mill chart for easier in-flight distance estimates
- A B737 is faster than a PA28 / C150 / C172 - if one is up your chuff, then go around!
PS bcfc - please let me know the registrations of all the aircraft you've lost Biros in, as I do not wish to fly them until a comprehensive loose articles check has been done by an LAE. They should all currently be grounded.
