My family and me remember late July 2019 in Luxembourg for its extreme hot record temperatures of 40 degrees Celcius. I’ve booked since quite some time a Cessna 172 SP – call sign LX-AIO – at my flying club Aéro-Sport for a long weekend fly-out. I always enjoy when my wife and 9 year old son are joining me for a flight. The extreme hot weather won’t keep me from flying to the French Riviera. Arriving in the Aéro-Sport clubhouse, another pilot informs me that the plane I booked, call sign LX-AIO, has an error with the G1000.
