Is it really a major problem for a pilot just to say "737"? I think not!
I wouldn't think so at first, but after reading your previous post:
you would not believe it but pilots are not beyond giving the wrong type on the R/T. Incredible, but true.
I started thinking about possible solutions to this waste of comms bandwidth and potential safety hazard.
Have you seen how inaccurate some of the info from ADS-B is? Hex codes are not 100% accurate by any means.
I am aware that hex codes are not 100% accurate, nor is anything else in surveillance. In civil aircraft the accuracy is I guess above 99%, military is lower. If you start using the hex codes for this purpose, the percentage will rise when you give feedback to the operators.
Sightly off topic:
Not sure to which inaccuracies in ADS-B you are referring to. There are quite a few aircraft that send inaccurate position, but they indicate that they do so and therefore can be identified as non-suitable ADS-B targets.
Few installations send misleading data. But there is improvement and I am sure that the wrinkles will be ironed out after the EC decides on the mandate for ADS-B in Europe.
Best,
