Pre-noting Class D transit requests

[Good Business Sense]

This is the thin end of a very large wedge - the AIC quotes some of the benefits as :

Enable better planning of transit flights through Class D airspace;
Reduce the RTF loading when requests are made;
Reduce ATC workload and therefore enable more efficient use of the airspace.

There is only one way to action the above - you'll get an email back saying "no, go away"
