Continuing through the looking glass, with it's usual regard for the taxpayer's dollars, Transport Canada Aviation Enforcement is paying for a substantial number of American aerobatic pilots to travel to Ottawa to discuss this bizarre interpretation of the Canadian Aviation Regulations. -- aboyd at igs.net ----- Original Message ----- From: "Max Braude" <skybird at optushome.com.au> To: "Andrew Boyd" <aboyd at igs.net>; "IAC Acro List" <acro at gf24.de> Sent: Friday, April 05, 2002 11:35 PM Subject: RE: [Acro] Aerobatics Now Illegal In Canada > Lets give 3 cheers to the beaurocrats > > > Again > > > > Max Braude > skybird at optushome.com.au > > > -----Original Message----- > From: Andrew Boyd [mailto:aboyd at igs.net] > Sent: Saturday, April 06, 2002 1:04 PM > To: IAC Acro List > Cc: aboyd at igs.net > Subject: [Acro] Aerobatics Now Illegal In Canada > > > According to Canadian Aviation Regulation (CAR) 602.27(c) flight > visibility of 3 miles is required to perform an aerobatic maneuver in > Canada.
