The invention discloses a full-aircraft drop test method and a full-aircraft drop test device for a principle prototype of a large anti-back headstand angle aircraft, and particularly relates to a method and a test device for keeping the time of the principle prototype consistent with the time of a landing dynamic process of an original aircraft in a drop test. On the basis that lifting and releasing of a small-size principle prototype can be achieved, equivalent simulation of dynamic response in the time period from the main landing gear to the front landing gear in the landing process of the principle prototype can be achieved in cooperation with a shrinkage specific gravity acceleration loading method and an aerodynamic force applying method, and therefore a full-aircraft drop test can be conducted in a limited site. According to the technical scheme, the device comprises a lifting and releasing device, a shrinkage specific gravity acceleration applying device, an aerodynamic force applying device and a force measuring platform; according to the invention, the consistency of a small-size principle prototype in the time period from the main landing gear to the front landing gear to the original aircraft can be realized.
