EPIC Platinum Performance Package
EPIC Performance Package
Swept Blade Turbofan Propellers (SBTP)
How do they work?
Raisbeck/Hartzell Swept Blade Turbofan Propellers for the King Air 250 utilize swept-wing technology to increase thrust while reducing noise and vibration. Certified by the FAA, EASA and ANAC, the Swept Props come with new Airplane Flight Manuals, making them compatible with all combinations of Raisbeck Performance Systems and carrying with it all of these systems’ FAA-approved increased performance levels.
If you want the most out of your aircraft, install our EPIC Platinum package with Swept Blade Propellers.
- Larger (96″) diameter, more powerful design develops more thrust without increasing noise or vibration
- You can feel the improved acceleration when you apply power
- Inherently improved performance in all phases of flight from takeoff to landing
- Made of affordable aluminum
- Trouble-free operation between 6-year, 4,000 hour overhauls
- Unique combination of aerodynamic technology and computer-aided manufacture
- Lightweight aluminum hubs and blades
- Oversized hydraulic power piston to lock in propeller synchrophasing
- Grease-lubricated hubs to preclude oil leaks
Ram Air Recovery System (RARS)
How does RARS work?
By making the airflow to the engine more efficient, the Ram Air Recovery System (OEM standard on new King Air 250s) decreases ITT 18° at equal torque, prevents FOD and increases all weather capability.
- Significantly improved climb and cruise performance with ice vanes stowed or deployed
- 18º cooler engine ITT at equal torque
- 8% increase in available horsepower
- 8% to 11% block fuel savings (as part of the 250 EPIC Platinum Performance Package)
- Ice vanes may be deployed at any time including taxi and takeoff when at OATs up to ISA +27ºC*—Use of ice vanes on RARS- equipped aircraft on the ground and during takeoff and landing minimizes the risk of foreign object damage.
- Developed and tested in conjunction with Pratt & Whitney of Canada, Ltd
- FAA-Certified for ice-vane deployment on the ground and in the air
- Utilizes coanda-effect aerodynamics for efficient airflow vectoring
- Full inlet plenum sealing through unique full-body diaphragms
Enhanced Performance Leading Edges (EPLE)
How do they work?
A key part of the King Air 250 EPIC Platinum Performance Package, Enhanced Performance Leading Edges significantly improve climb and cruise performance and reduce stall speeds, along with other benefits.
- Increased cruise speeds
- Reduced stall speeds
- Increased outboard wing life
- More efficient air conditioning through improved intercooler efficiency
- Excellent low speed flying qualities and stall characteristics
- Modern aerodynamic airfoil improves airflow
- Composite construction for strength and weight savings
- Recessed flush-mounted de-icing boots minimize drag
- Extended de-icing boot material protects intercooler inlet from foreign object damage
- Optimize intercooler inlet and ducting
Dual Aft Body Strakes (DABS)
What do they do?
Raisbeck’s Dual Aft Body Strakes improve directional stability, passenger ride quality, pilot control and aircraft handling characteristics, and climb and cruise performance. Wing/body vortices normally disrupt airflow under the aft fuselage, creating drag. Dual Aft Body Strakes eliminate this separation, channeling the vortices and accelerating the air—in effect, pushing the airplane through the air.
Factory-installed on all new King Air 350s, Raisbeck Dual Aft Body Strakes are The New Standard—plus, they will give your King Air 250 a fresh, modern appearance.
- Eliminates yaw damper inoperative altitude limits, increasing your dispatch reliability
- Improved directional stability and pilot control
- Reduced drag in all flight modes
- Improved passenger ride quality
- Quieter cabin and cockpit
- Increased climb and cruise performance
- Inherently reduced minimum control airspeed
- Classic Beech ventral fin is removed
- The shedding wing/body vortices are captured under the aft fuselage pressurizing and reducing aft-body drag resulting coanda-effect attaches the aft-body airflow
- Equivalent vertical tail area is increased
High Flotation Gear Doors (HFGD)
Does your King Air 250 have high flotation gear?
If so, our fully-enclosed High Flotation Gear Doors will restore the climb and cruise performance lost with high flotation gear. That’s why they are a key element of Raisbeck’s EPIC Platinum Performance Package.
For military ISR operations, our High Flotation Gear Doors reduce drag and thereby increase loiter time by 30 minutes or more!
- Restore the climb and cruise performance to that of King Air 250s equipped with standard gear
- Cruise speeds are increased by 4-10 knots
- Wheel wells, tires, wheels and brakes are protected from the elements
- Fully encloses the protruding high-flotation gear, wheels, and tires
- Aerodynamically area-ruled to maximize drag reduction
- Constructed of lightweight composites for maximum strength and minimum weight
Crown Wing Lockers (CWLS)
Return your cabin to your passengers!
Raisbeck’s Crown Wing Lockers give you the extra, secure storage you need outside the cabin, with no performance penalty. The Lockers can accommodate skis, snowboards, camping/hunting/fishing gear and other long items that can’t be legally carried inside the cabin.
- Certified for 600 lbs (300 lbs per locker) in nearly 17 cubic feet of stowage space
- Carry oversized luggage and full size golf bags
- FAA-certified for FAR Part 135 operations
- Free up seats for additional passengers
- Save on interior wear and tear
- Watertight, lock-and-key security
- Lightweight composite construction allows for infinite-life structural certification
- Aerodynamically area-ruled to minimize drag
- Fully self-contained for a clean and dry locker interior
- Removable in minutes for airplane maintenance or inspections
