    Carbon Fiber Tube Fuselage

    CF is without question the highest performance material we have where high heat exposure is not an issue. It is used in virtually all high performance, competition applications. Formula 1, Reno F-1, Sport and Biplane classes, B777, etc, etc. So l'd probably look to them for design and...

Then RNAV came along that did fancy stuff with DME and VOR to let you go somewhere other than direct to/from a VOR station. Sometimes a self-contained INS (inertial navigation...

    FAA Failure #119
