Yesterday, CHIRP Aviation held the 100^th General Aviation Advisory Board at White Waltham. For CHIRP, which started in 1982, the advisory boards are fundamental to our commitment to improving air safety. These teams of experienced aviation and human factors professionals review all CHIRP reports, providing advice and guidance for the resolution of safety issues, raising awareness of safety concerns and promotion of key messages. For our milestone meeting, the sun shone and several members were able to fly in. We were very kindly hosted by the West London Aero Club and thanks go to Catherine, Rob and the team for looking after us superbly at this wonderful location.
