FLIGHT & TEST CELL TELEMETRY
Ready to sample with P_excess/W = 8.0 m/s.
Adjust P_excess/W, then execute aerospace trial.
Aeronautical telemetry and flight states are evaluated rigorously using 64-bit IEEE 754 precision. Residuals reflect ordinary least-squares regression across successive observations. Continuous data structures support high-fidelity aerodynamic modeling.
Aeronautical assumptions and boundary condition limits
Small climb angle assumption (sin(gamma) approx gamma and cos(gamma) approx 1) assumes gamma < 15 degrees; higher angles require full trigonometry. Linear regression of rate of climb against specific excess power yields an exact transmission slope of 1.0000 with R^2 > 0.999999.
