# Beechcraft Bonanza V35B — Normal Operating Procedures

> **NOT FOR FLIGHT** — source fidelity: not_applicable | operational review: none | completeness: normal_only | 1 unresolved safety defect(s)

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.

> **safety_defect**: Contains no airspeeds, power settings, fuel quantities, manifold pressure limits, or other numerical limitations — all must come from the specific aircraft POH.
> **content_gap**: Equipment, avionics, and fuel system configurations vary across V35B airframes. Verify every item against the specific aircraft and its POH before use.
