Reg Number Size/Location

Thanks Rob. So I guess the Skymasters I see with numbers on the boom sides are maybe using less than 12" numbers under the more than 30 years old provision?

The FAR leaves a lot of wiggle room.

I left the small registration marks on the booms and put an oversized version under one of the wings. If I ever have to wing waggle beside an F-18 they won't miss it.

I went through ADIZ hundreds of times between So. Florida and the Bahamas over a 15 year period with the numbers on the booms and never had an issue.

Never a problem until they get the tape measure out. 10" numbers are standard on the booms because the 12" wrap around too far. Most would never know the difference anyway

Thanks for the insights. Just going to go with what fits, i.e. c10". I've been operating this airplane around the ADIZ for going on four years with 3" numbers; just wanted to try to comply with the reg now that it's finally getting repainted. In fact was out today operating just east of the presidential TFR out to the ADIZ.

Of course with the faux O-2B paint scheme it looked pretty official...maybe I shoulda' just left it alone!
