  "description": "Emergency procedures for the Beechcraft Bonanza A36 with Continental IO-550 fuel-injected engine, constant-speed propeller, and retractable tricycle gear. Memory items are marked. All airspeeds and numerical limits must come from the specific aircraft POH. The IO-550 is fuel-injected — carburetor ice is not applicable. Retractable gear requires specific gear-unsafe and emergency-extension procedures; locate the emergency gear extension handle before flight. Not a substitute for recurrent emergency training or qualified instruction in type.",
