Any ATC Specialist Help With A Question?

Sun Dec 04, 2005 12:37 am

Can any of you ATC guys help me with a question.

Looking at the ATC displayed aircraft types show for example B72Q/A or /R or /A or /Q

Basically what does the / other letter signify?

It seems /A is something to do with RVSM restrictions at or below FL 280. That's about all I could make of it.

Any help would be appreciated.

You guys in the US use different Saftey Equipment codes to the Rest of the worlds.

A= RVSM limited to FL280
R= VHF ONLY
Q= VHf & HF freq's

Thats what kennedy Centre told me when I asked, as they refused my FPL, because I didn't fill in the A/R/Q field.

I don't know what the letters for 727s stand for, but letters following the type of airplane usually refer to what optional safety equipment that the plane has installed in it. This can be anything from navigational aids to emergency equipment. I believe the letters you said have to do with communication.

If you have never designed an airplane part before, let the real designers do the work!
