Alignment defect compensating method for airplane, involves determining gaps i.e. positioning errors, between theoretical sight line of equipment and aircraft sight line, and carrying out correction operation to eliminate errors

摘要

The method involves choosing a direction i.e. aircraft sight line, fixed with respect to a structure of an aircraft i.e. airplane, and a structural element e.g. chair, fixed with respect to the structure of the aircraft. Angular gaps i.e. positioning errors, between a theoretical sight line (12) of corresponding equipment e.g. head-up display device (5), and the aircraft sight line are determined for equipment supports e.g. head-up display support. A correction operation is carried out using the positioning errors to eliminate the positioning errors.
