Since the development of digital design for aircraft

the accuracy and quality of aircraft assembly have been greatly improved. At the same time

new requirements have been put forward for the measurement of assembly process. Therefore

only through efficient measurement means and schemes can the aircraft assembly accuracy be satisfied. Based on the establishment of measurement system and the transfer station technology of laser tracker

this paper studies the measurement technology of attitude adjustment of large components of the large-scale fire extinguishing/rescue amphibious aircraft AG600. The attitude adjustment measurement of the aircraft’s large parts is based on the measurement of several reference points on the parts by laser tracker

and the adjustment of the aircraft’s attitude is realized by flexible assembly tooling

so as to meet the requirements of the aircraft installation. For the traditional measurement method

the laser tracker is used for the transfer station measurement

which is the simplest and most effective method for the large aircraft parts docking measurement.
