Tanagra Flight Dynamics & Airshow Safety Floor Analysis
High-performance swept-wing interceptors like the McDonnell Douglas F-4E Phantom II operate with a wing loading exceeding 85 lbs/sq ft. In a descending turn or split-S pull-out, altitude loss scales quadratically with true airspeed: ΔH_recovery ≈ (V_dive² · sin θ) / (2·g·(N_z - cos θ)) + V_dive · t_delay. When entry altitude falls below the critical threshold or G-onset is delayed by pilot reaction or wing buffet margins, ground impact occurs within 3.5 to 5.0 seconds. Regulatory airshow standards (HAF / FAA Order 8900.1 / ICAO Annex 6) mandate strict aerobatic floor limits (typically 500 to 1,500 ft AGL) precisely to prevent aerodynamic stall departure during vertical recovery.
