Last Thursday, a Boeing 777 crashed while on final approach at London’s Heathrow Airport. The initial report from the UK’s Air Accidents Investigation Branch (AAIB), indicates the plane did not respond after the pilots pushed the throttles forward for more power. The aircraft landed about 1000 feet short of Runway 27L. 152 people were on board and 13 people were injured.
How is it that a US$200 million airplane does not respond when the throttles are pushed forward? This plane, and many others like it, — including some newer GA piston powered aircraft — utilize computer software to control all aspects of engine operation. This system is called Full Authority Digital Engine Control (FADEC). Read more about FADEC after the jump…

The family and I took a trip up to Omaha on Thanksgiving Day in the Diamond DA40XL. Weather was forecasted to be good, however, there was some warmer air aloft and I had some concerns of visibility due to the recent snow fall to our north (colder ground temperatures). The issue was that the Blair airport had no published instrument approaches. We decided to proceed with the flight as visibility was good (10+ miles), there were no icing concerns, and if we could not get VFR into Blaire, we’d go to Omaha International as our alternate. We’d also watch the XM Weather close on the flight up to see if the weather closed in on us en-route.

A lot of you have been emailing me and are interested in my Robinson R22 cost calculations that I mentioned in this post. I came up with this spreadsheet (posted as a JPEG file below) after looking at lots of new and used Robinson R22s and concluded that if you have the appropriate cash flow, it can be cheaper to buy a new Robinson R22 for initial helicopter training and fly it for 5 years vs renting. I’d welcome your comments on my cost estimations.
