What a load of crap!
Reading that it would seem to suggest that if an Airline Pilot flies a twin occasionally and a single they would need to do their cyclics plus a twin engine class flight review plus a single engine flight review. To keep a night VFR then one of those would need yo be at night.
An IR renewal would cover the reviews as now?
In the USA you only need to do one class, and it can be in a glider!
Here I need the glider review every year as well!
This might shut up some of the bleating from GA flying schools, plenty of extra work for them.
