← TechnologyWhich risk increases when hydraulic pressure is lost to an airplane's flight controls at high altitude?
A)Elevated stall and spin propensity✓
B)Increased engine fan blade erosion
C)Elevated parasitic drag coefficient
D)Compromised avionics processor cooling
💡 Explanation
Elevated stall and spin propensity increases because the diminished control authority reduces a pilot’s ability to correct for aerodynamic instability using flight surfaces, therefore stall/spin, rather than safe flight arises, because the aerodynamic control is degraded. at high altitudes
