Noise complaints at Tyagarah are not new at all.
We had complaints when I flew skydivers there in the late 80's and VH-DPI was a HELL of lot noisier and slower to climb than the C208's.
Maybe the current owners need to install security like Cptn Ron L had. Two fierce dobermans let loose in the hangar at night. Maybe they need some deterents chained up around the van ?
And totally agree, that an hour of ICUS with Al, would have them calling the cops
I've witnessed new trainee pilots leave, after session with Al in a C182, almost in tears after he stripped any sense of "Sky God" like thinking from them. Some deserved it and some just rubbed him the wrong way.
