Are you seriously telling everyone (and there are people on here who believe things that are said) that VFR pilots should PLAN on going through CAS?
Absolutely 100% they should have a plan that if appropriate to the route goes via controlled airspace class B,C,D,E,F and G. i.e. airspace
available to VFR flights
Too many pilots plan to fly in various Shaped routes avoiding every bit of class D and then when cleared through have no established plan to do so which leaves them heading into controleld airspace without any pre-planned heanding or route and opens up the posibility of wandering round inside the zone which I believe is worse than wandering round outside it.
Of course everyone should have a
back-up plan for a delayed or refused clearance which could be simply hold until you get one and/or divert or both.
However, VFR flights are no different from IFR flights - they plan a route via the airspace they are permitted to fly in and where necessary request ATC clearance.
IFR flights legally require the exact same clearances as VFR flights for every bit of airspace they fly through. In most places the clearance is automatic for an IFR flight to reduce unnecessary R/T - in many other places it is not.
There is no real difference legally between an IFR flight from Heathrow to New York requesting a clearance to transit the Shanwick and Gander OCA's and a VFR flight requesting a transit of the Solent CTA. In both cases ATC can refuse. In both cases the pilots can come up with an alternative plan that enables the destination to be reached but costs lots more and in both cases it is an ATC reason for not getting a clearance. So the extra cost to the operator in both cases is a result of ATC capacity.
Pilots should not hesitate to plan reasonably via all the airspace classes that they are legally entitled to fly in. They should request a clearance when appropriate and they should have an alternative plan should a clearance not be available.
Can you please tell me where IFR or VFR is mentioned in the previous paragraph?
Can you tell me what is unreasonable from a safety or legal point about the same paragraph?
Disclaimer;
None of the above should be read as encouraging IFR or VFR flights to plan via airspaces where known restrictions or ATC actions cause frequent unnecassary delays if there is an alternative route that avoids the issue.
