Letters can be angled back or forward up to 350
Letters cannot be arranged vertically down a tail or other surface (they have to run
parallel to the longitudinal axis)
Pay attention to the hyphen, it should be 2/3rds of the height of the lettering
And many, many more rules!
The rules for markings are very complex, so read them carefully before you apply your markings!
Certificate of Airworthiness
New and used certified aircraft will come with an existing C of A. The C of A does not specify an owner, so it is valid even after the aircraft changes hands – just keep it in the aircraft, it remains valid!
If you are importing a certified aircraft there is a requirement for an import inspection. Complete information on this process is available in The COPA Guide to Buying an Aircraft.
Weight And Balance
New and used certified aircraft will come with an existing weight and balance report, done when the aircraft was manufactured. If the aircraft has had changes to the equipment installed then it will have amendments to the original weight and balance report.
A copy of the original weight and balance along with amendments must be carried in the aircraft.
If aircraft owners want to learn more about weight and balance procedures, there is a great reference book that walks you through the whole process in great detail, with lots of diagrams and examples. The FAA publication AC 43.13-1B Acceptable Methods, Techniques and Practices, Aircraft Inspection and Repair has an entire chapter on the weight and balance (Chapter 10), is the standard reference on the subject and is accepted by TC in Canada. The good news is that you can download the entire book for free as Adobe Acrobat files from the FAA website.
