Flight Mechanics, Stability & Control

Use this for “A 10,000 N airplane has S = 16 m² and CLmax = 1.6. Find its stall speed at sea level, ρ = 1.225 kg/m³.”

Use this for “A jet cruises at 230 m/s with L/D = 16 and cₜ = 0.6 per hour. It starts the cruise at 600,000 N and burns 120,000 N of fuel. Find its range.”

Use this for “A 50,000 N airplane at 80 m/s has 6000 N of thrust and 3553 N of drag. Find its rate of climb and climb angle.”

Use this for “An airplane flies a level turn at 80 m/s, banked 60°. Find the load factor, the turn radius and the turn rate.”

Use this for “Find the standard-atmosphere temperature, pressure and density at 3000 m.”

Use this for “An airplane has Cₘ₀ = 0.05 and Cmα = −0.012 per degree. At what angle of attack does it trim, with Cₘ = 0?”

Use this for “An airplane has Cₘ₀ = 0.05 and Cmα = −0.01 per degree. Is it stable, and does it trim at positive lift?”

Use this for “A mode’s eigenvalues are λ = −0.5 ± 2i per second. Find ωₙ, ζ, the period and the time to half amplitude.”

Use this for “An airplane’s nose wags left and right while its wings rock. Which mode is it, and is it longitudinal?”

Use this for “What bank angle gives a standard-rate turn of 3°/s at 60 m/s, and what load factor does it pull?”

Use this for “Which axis does a canard control, and which do roll spoilers control?”
