PDC Examples
Here are some examples of various Pre Departure Clearances:
"Clearance delivery" on Tower VHF frequencies has been
around for many years and took up a lot of time reading the long
message and then asking for a "read back". But a few years ago
the FAA got into the 21 Century and started using ARINC'S ACARS
system to deliver these clearances over the local ACARS fre-
quencies at selected airports around the country.
This could be the first step to the FAA using
digitalized communications for many other ATC clearances. They
have said they are planning for this. But instead of using a
proven existing system, they are planning to invent an entirely
new operation using transponder fequencies!!!! This should be
interesting!
Except for Air Canada, I have not found any foreign
carriers making use of this as yet. Maybe, you all might have
caught such a message. I'd appreciate your help in letting me
know who they are.
The following are a few examples of PDC (Pre Depature
Clearance) messages I've copied. The transmission "times" are
given after the upload and sometimes at the start.
