Questions Before You Call? Here Are the Answers
1. How much speed can a 5-blade prop add to a King Air 200?
Published MT-Propeller data for the 5-blade MTV-27 installation on the King Air 200 series reports approximately 3 knots of cruise-speed improvement at 1,800 propeller RPM, along with improvements in takeoff and climb performance. Actual results can vary based on aircraft configuration, engines, weight, altitude, and existing modifications.
If you are evaluating a propeller upgrade for your King Air, contact Dave Chapman to discuss your aircraft, mission, and available upgrade options.
2. What are the quietest propellers for a King Air 200?
For King Air 200-series aircraft, the 5-blade BLR Whisper Prop is designed to reduce noise and vibration compared with traditional propeller configurations. In BLR’s published King Air 200/250/260 propeller comparison, the 5-blade Whisper Prop recorded 77.7 dB(A), lower than the 4-blade and other 5-blade systems included in that comparison.
Actual cabin and exterior noise levels can vary depending on propeller RPM, aircraft configuration, operating conditions, and other modifications.
3. Which Beechcraft King Air models can be upgraded with Whisper Props?
Whisper Props composite propeller retrofits are FAA-certified for major Beechcraft models, including the King Air 200 / B200 series, King Air 350 series, and King Air C90 variants.
4. What are the benefits of putting a 5-blade prop on a King Air?
A 5-blade composite propeller can provide several benefits beyond appearance. On the King Air 200 series, published benefits associated with the MT 5-blade system include reduced cabin noise and vibration, improved takeoff and climb performance, a modest cruise-speed improvement, increased ground clearance, reduced exposure to foreign-object damage, and lower propeller weight compared with the original 4-blade aluminum configuration.
The exact benefits depend on the King Air model, current equipment, and mission profile. Contact Dave Chapman to review the available propeller options for your aircraft.
5. How do Whisper Props reduce cabin noise and vibration in a King Air?
Whisper Props feature optimized composite blade sweep and lighter overall weight, which alters aerodynamic resonance and drastically lowers interior decibel levels. This results in a noticeably quieter cabin experience, reduced pilot fatigue, and smoother flight characteristics from takeoff to landing.
