1. A method generating estirnated air speed data and/or dynamic pressure comprising kinetic energy per unit volume of fluid moving around the aircraft, comprising:
on board an aircraft, using only plural sensors that do not depend on any measurement of total pressure or static pressure to sense a set of sensed parameters other than air data based on air flow pressure measurements, the set of sensed parameters consisting essentially of:
(a) Estimated aircraft weight,
(b) Ground Speed (GS),
(c) Geometric Altitude,
(d) Angle of Trajectory (Gamma),
(e) Angle of Attitude (Theta),
(f) Longitudinal Acceleration Load Factor (Nx),
(g) Lateral Acceleration Load Factor (Ny),
(h) Vertical Acceleration Load Factor (Nz),
(i) Delta Temperature from Standard Atmosphere or Total Air Temperature, and
(j) Engine's Magnitude of Thrust; and
with at least one processor connected to the plural sensors, operating a trained neural network on board the aircraft to estimate air speed data and/or dynamic pressure comprising kinetic energy per unit volume of fluid moving around the aircraft based on said set of sensed parameters other than air data based on air flow pressure measurements and without requiring measurements by pilot tubes or other sensors that measure total pressure or static pressure based on pressure lines that may be blocked by unintended objects.
