I'm brand new to x plane and pilot edge.
Just passed my V-1
The controller said in the future to change my tail number/ ID as It ends in
Papa Oscar ( or something)
And the Oscar could be confusing in the future.
Do I then just choose a random identification number?
It can't be totally random. It has to follow a few rules. For a U.S. tail number it must start with the letter "N" and then as follows: (from Wiki)
An N-number may only consist of one to five characters, must start with a digit other than zero, and cannot end in a run of more than two letters. In addition, N-numbers may not contain the letters I or O, due to their similarities with the numerals 1 and 0. The following are the combinations that could be used:
N1 to N99 — Federal Aviation Administration (FAA) internal use only
N1A to N9Z
N1AA to N9ZZ
N10A to N99Z
N10AA to N99ZZ
N100 to N999
N100A to N999Z
N100AA to N999ZZ
N1000 to N9999
N1000A to N9999Z
N10000 to N99999
