  "description": "Normal operating procedures for the Beechcraft Bonanza V35B with Continental IO-520 fuel-injected engine, constant-speed propeller, and retractable tricycle gear. The V35B features the distinctive V-tail (butterfly tail) with ruddervator surfaces that combine rudder and elevator function; pilots transitioning from conventional-tail aircraft should seek qualified instruction. Covers preflight walk-around through shutdown and securing. All airspeeds, power settings, fuel quantities, manifold pressure limits, RPM settings, and performance data must come from the specific aircraft POH. Not a substitute for qualified instruction or type-specific training.",
