    Bird Strike Windshield Test Temperature

    RB Later this winter when the temperatures get really cold. Take of one of your gloves off and touch the window next to you; then come back and tell me its RT. The plastic is fairly slow to change its temperature, but after an hour + cold soaking at altitude the windshield is quite cold. I...

    Bird Strike Windshield Test Temperature

    I promised you all the answer to the question. 1) Nobody every knowingly shot a frozen bird at a windshield or engine. 2) I am the DER and I did consult with the FAA. 3) Yes, the majority of bird strikes occurr below 10,000 ft, however only moments prior to reaching 10K the aircraft was...

    Bird Strike Windshield Test Temperature

    Cedar Finally a comment worth responding to. That is not currently in the plan, but it definitely has merit. I can say with great confidence that the window will not fail if the window is rolled down. The only problem at that point is having an adequate early warning system to give the pilot...

    Fatigue damage due to compressive load

    I have been involved in two cases where what appeared on the surface to be a compressive load environment resulted in cracks developing. Both in the area of the landing gear. The problem was a very high and very local compressive stress resulting in very local plastic deformation that when...
