Is the communication on the recording real time or has it been edited? The lesson I take away, at this point, is when you have a failure of any critical instrument in IMC conditions, act quickly to improve your situation regardless of backup instruments. Still, that's easy to say as I sit here....... I theorize that he was over controlling. Few steam gauges will keep up with abrupt control inputs. There is a slight lag and not every instrument does so at the same rate. In IMC I can envision a situation where he's over controlled to the degree that his wet compass, DG and TC, VSI and Altimeter are not in agreement and he's trying to figure out what to do. At that point the best answer is probably to do nothing...until everything settles. It's unfortunate he didn't have something as simple as a wing leveler. While crude by today's standards, I know it will keep the plane upright sans vacuum. If I found myself in IMC sans vacuum, I think I could pretty safely fly with elevator and roll trim only. The old Brittain unit limits bank angle to about 20°. Quote Link to comment Share on other sites More sharing options...

carusoam Posted May 7, 2016 Report Share Posted May 7, 2016 Here's where they find a friend to ask his opinion... http://www.nbcconnecticut.com/news/local/NTSB-Updates-Small-Plane-Crash-Bristol-Connecticut-Long-Island-378147591.html with before and after photos of the plane... the first video looks like the V separated from the rest. prayers, -a- Quote Link to comment Share on other sites More sharing options...

The old Brittain unit limits bank angle to about 20°. Are you sure the wing leveler would still work without vacuum? I believe that it would be inoperative without vacuum. The Brittain uses vacuum to suck the boots and to make the gyro turn... for my 1965 C model. Yves 1 Quote Link to comment Share on other sites More sharing options...

The TC would work, but the PC relies on vac so no wing leveler and no roll trim. Quote Link to comment Share on other sites More sharing options...
