Bugs me too.
White Cessna? Which one? 99% of them are white. How about Skyhawk 345? Well, that’s a bit more descriptive, since the registration number is a legal ID according to the FCC (which regulates the radio side of the house.) I know you’re probably a high wing and going about 90 kts. Same for “Cherokee 68W”. Low wing, can see me if you’re turning, and what your silhouette looks like. “Malibu 21TB?” Gotcha…
Last call? Another affectation. Make the call leaving the pattern if you must “skyhawk 345 departing pattern northwest, east jabip”, but I really don’t give a fig that you’re not going to be clogging up the frequency (and probably made the 'any traffic…" call earlier) anymore. You’re out of the pattern. Bye. Don’t need to hear from you anymore.
