NASA Reference Publication 1207 Derivation and Definition of a Linear Aircraft Model

The Truth is the LIGHT

Nasa reference publication 1207 – 1988: derivation and definition of a linear aircraft model — plane not a planet.

Busted! Abstract: A linear aircraft model for a rigid aircraft of constant mass flying over a flat, nonrotating earth is derived and defined. The derivation makes no assumptions of reference trajectory or vehicle symmetry. The linear system equations are derived and evaluated along a general trajectory and include both aircraft dynamics and observation variables.” LINK […]

15 Aeronautic Research Papers & Technical Memos That Assume A Flat and Nonrotating Earth!

Below are 15 research papers and technical memos that describe how aircrafts, helicopters, or unguided missiles lift off, fly above, and land upon the earth. in each case, the aeronautical engineers assume the earth to be flat and non rotating. so where is the paper that assumes round and rotating good luck .. .
