Thanks for your reply JD.
What I am leading up to is a belief that MATZ as they stand are a waste of space. They are supposed to protect arriving/departing traffic.
To my mind they are more like magnets for overflying spotters.
Why plot a route through someones overhead at 2-2500' on a cloudy day when the bases are trying to launch/recover in DS conditions.
Or worse 1500' on a sunny day getting in the way of circuit traffic.
It's all a bit illogical and occasionally dangerous.
The majority of transits I speak to are very professional and very understanding and adjust or reroute.
A significant number of others are of the "I don't care I'm coming through" and sod your patterns/emergency aircraft inbound. Quote " To reroute would cost me money" That was versus a Mayday. Shocking.
Over to you lot. Tin hat on.
