  "description": "Normal operating procedures for the Diamond DA40 with 180-hp Lycoming IO-360 engine and constant-speed propeller. Covers preflight walk-around through shutdown and securing. Contains no numeric limitations; all speeds, fuel quantities, power settings, and performance values must be obtained from the specific aircraft POH/AFM. Accounts for the DA40's composite construction, T-tail, canopy-style entry door, left/right/both fuel selector, sidestick controls, and constant-speed propeller. G1000 glass panel is common on this type; verify avionics items against the specific aircraft configuration.",
