Sep 23, 2017 · The height that separates geoid and WGS-84 ellipsoid is the geoid undulation. 1.4.9: Geoid undulation is required for airport elevations, runway thresholds and touchdown and lift-off areas (TLOFs) or thresholds of final approach and take-off areas (FATOs) at heliports. (See also Appendix B.)
Jun 25, 2016 · Air between condensation trails moves at the same speed (except the undulation). There are two interleaved helices for a two-blade propeller. Related effects: The P-factor produces an additional yaw moment. An increase in the propeller power changes the downwash, hence the efficiency of the horizontal stabilizer, and a pitch tendency.
Jan 21, 2015 · For slope change between 2 consecutive slope should be: <1.5% for code number 3/4. <2% for code number 1/2. And for transition from one slope to another should be: <0.1% per 30m code number 4. <0.2% per 30m code number 3. <0.4% per 30m code number 1/2. This is the global standard, some aviation authority such as FAA my have stricter rules.
Nov 24, 2016 · 14 CFR 1.1 defines night as the period between the end of evening civil twilight and the start of morning civil sunrise. This definition is again referenced in 14 CFR 61.109. Therefore day is defined as the period between the start morning civil sunrise and the end of evening civil twilight. That being said the regs also refer to night time as ...
Sep 16, 2019 · Does the FAA give a regulatory definition of the term "Touchdown Zone" for use within the context of landing operations? In 14 CFR 91.175 the FAA requires—in certain cases—that pilots mu...
Lateral stability is roll stability: the tendency of the aircraft to reduce its rolling and return to an upright position unless continually maintained in position by e.g. the ailerons.
HIGH SPEED TAXIWAY− A long radius taxiway designed and provided with lighting or marking to define the path of aircraft, traveling at high speed (up to 60 knots), from the runway center to a point on the center of a taxiway. Also referred to as long radius exit or turn-off taxiway.
FAR 99.3 says: Air defense identification zone (ADIZ) means an area of airspace over land or water in which the ready identification, location, and control of all aircraft (except for Department of Defense and law enforcement aircraft) is required in the interest of national security.

The FAA defines several different types of aircraft, which have different applicable regulations. For fixed-wing aircraft, airworthiness for normal, utility, acrobatic, and commuter categories is covered in Part 23.
We can also define a wind-axis Euler roll angle (or bank angle), maybe call it $\mu$. But that expression is significantly more complex than the angular velocity expression above. So, no, your expression for $\mu$ is incorrect. If that's your desire, then the expression you should consider is:
