First Claim
1. A system used to establish a physical reference within an airplane representing an optimized line of flight for the airplane, comprising:
- a tool positioned outside the airplane and including a tool reference surface;
means for calculating values for aerodynamic pitch, roll, and yaw of the airplane representing the optimized line of flight;
means coupled with the calculating means for moving the tool reference surface to an orientation corresponding to the calculated values for aerodynamic pitch, roll, and yaw of the airplane representing the optimized line of flight; and
means for transferring the orientation of the tool reference surface to a location inside the airplane.

Abstract
A method is provided for establishing a physical reference inside an airplane representing the airplane'"'"'s optimized line of flight based on the as-built orientation of aerodynamically significant features of the airplane. Values generated for aerodynamic pitch, roll and yaw representing the optimized line of flight are used to orient a tool reference surface outside the airplane. The orientation of the tool reference surface is recorded using an inertial reference unit placed on the tool reference surface. The tool reference surface and inertial reference unit are moved into the airplane where they are used to establish the physical reference on the airframe.
