The FAA Normal category weight limit of 12,500 pounds is exceeded by certifying the 200 series King Air in the Commuter Category. Fly Farther The weight increase allows more payload that can be more passengers, baggage, fuel, or a combination of these three. The 920 pound increase equates to an additional hour and a half of flight time, or, five more passengers plus baggage. Fly Faster The conversion provides an increase in the maximum operating Mach number, M mo . The original M mo is increased from 0.52 to 0.58 Mach. It allows faster cruise speeds at high altitudes and faster descents. This new feature is a real benefit for airplanes with -52 and -61 engines. *Please note the Mmo is not changed on King Air 200T and B200T series airplanes.

HALO 250 Performance and Configuration Options Option 1 or Option 2 — The Choice is Yours! There are two options available in the HALO 250 conversion. Option 1 — Normal Category: MTOW is unchanged at 12,500 lbs. Safety systems are fully operational. No change to the Beechcraft POH performance data. Option 2 — Commuter Category: MTOW increases to 13,420 lbs. HALO 250 AFMS performance data are applicable. Option 2 gives you all the benefits of the HALO 250 conversion. BE-200 type rating is required. Changing from Option 2 to Option 1 is Simple! If needs dictate operating the airplane in normal category, a change back to Option 1 is a simple four step process. 1. Remove the Commuter Category placard and AFMS 006-2 from the cockpit, 2. Place AFMS 006-1 in the cockpit, 3. Make an entry in the airplane’s records stating the airplane is now modified in accordance with STC SA11103SC Option 1, 4. Change the Airworthiness Certificate to show the airplane is in Normal Category. Whichever option you choose, you still have the benefits of the safety systems provided by the HALO 250 conversion. Takeoff Performance — It’s Better Than You Think! “Balanced field length” is another moniker for the runway distance sufficient to 1) abort a takeoff and stop the airplane on the runway, or, 2) continue the takeoff and reach a height of 35 feet in the event of an engine failure just before decision speed. Airplane certification regulations require that the

relationship between outside air temperature, pressure altitude, gross weight, and the resulting takeoff “balanced field length” be provided for Commuter category airplanes. This requirement increases safety because the contingency of an engine failure is included in the takeoff distance. The HALO 250 AFM Supplement provides easy-to-use tables containing balanced field lengths and takeoff speeds. The takeoff speeds have been optimally selected to shorten the balanced field length as much as possible. The result is shorter runways can be utilized without compromising the added safety that “balanced field” takeoff operations provide. 11,000 AIRCRAFT GROSS WEIGHT ~ LBS RUNWAY REQUIRED FOR TAKEOFF ~ FEET 3,000 3,500 4,000 4,500 5,000 5,500 6,000 11,500 12,000 12,500 13,000 13,500 CONDITIONS: Field Elevation: 1,000 Feet MSL Temperature: 13° C ISA Day Wind: None B200 POH Accel Go Distance HALO 250 Balanced Field Length HALO 250 Reduction in Takeoff Distance HALO 250 Balanced Field Length Compared to B200 Accel Go Distance “Making Aviation Better!” Effect of Icing — It’s Better to Know Before Finding Out! The HALO 250 AFM Supplement provides the performance charts and tables you need to predict rate-of-climb and net climb gradient for flight operations in icing conditions. These new data makes it easier to ensure safe operation in icing conditions, even in the event of an engine failure. Additionally, the conversion includes an update to the stall warning system that greatly improves the accuracy of the stall warning when there is ice on the wings. These new features make operating your King Air 200 in icing conditions safer. Simulator based flight training is currently available at TRU Simu- lation + Training (www.truesimulation.com), FlightSafety Interna- tional (www.flightsafety.com), and FlyRight Inc. (www.flyright- inc.com) using their FAA-approved, full motion simulators. In-aircraft flight training is also available at CenTex Aerospace and Executive Flight Training (www.kingairtraining.com). 4 CENTEX AEROSPACE GWI STC SERIES Training Increased Safety In the ice mode, stall warning occurs at a lower angle-of-attack that compensates for the reduction in stall angle-of-attack caused by ice on the wings and tail. This is a new advanced safety system for the King Air 200 series airplanes and is only found on airplanes with the HALO 250 conversion. Engine Fire Extinguisher System: Engine compartment fire extinguishing capability is required by Commuter catego- ry regulations and is added by the Halo 250 conversion, if not already present. This system complements the standard King Air 200 fire detection system providing complete detec- tion and protection from an engine fire. System status annunciators and activation switches are added to the glareshield allowing the pilot to test the system and activate it when needed. Cabin Emergency Lighting System: A cabin lighting system consisting of two LED flood lamps and a battery pack is installed to provide lighting in the cabin in the event of a loss of electrical power. Also, a g-switch activates the flood lamps should the aircraft experience deceleration beyond normal operations, such as a crash landing. This is a new feature for the King Air 200 series airplanes. The cabin emergency lighting system also can be used to aid in normal loading or unloading of passengers or cargo. Takeoff trim warning system — Aural alert when elevator trim is not properly set for takeoff. Escape path markings — show pathway along cabin floor to main door and emergency exit. Ice mode stall warning system — Improved stall warning when there is ice on the wings. Engine fire extinguisher system — Protection from a fire in engine compartment. Engine fire extinguisher system — Protection from a fire in engine compartment. Emergency cabin lighting system — Illumination of cabin during emergency situations. Over-speed warning system — Aural alert when Vmo /M mo is exceeded. New Safety Systems Make Your King Air 200 Safer FAA regulations require safety systems normally found on jet transport airplanes to be installed on Commuter Category airplanes. The HALO 250 conversion adds five new systems to the King Air 200 making it a much safer airplane to operate. Here is a description of what these systems provide. Trim Out-of-Range Warning System: An aural warning sounds to alert the pilot that the elevator trim tab is not set within the takeoff range when the airplane is on the ground and engine power is advanced for takeoff. This is a new feature for the King Air 200 series airplanes. Over-Speed Warning System: An aural warning sounds to alert the pilot that airspeed has exceeded the maximum operating airspeed or maximum operating Mach number. This is a new feature for the King Air 200 series airplanes, except those with the Rockwell Collins Proline 21 avionics suite. Stall Warning System Ice Mode: The aural stall warning system is updated to add an “ice mode” that automatically activates when the surface de-ice system is first operated. It remains in operation until the pilot manually switches back to the normal mode after the airplane exits icing conditions and the wings are free of ice. © 1/2019 CenTex Aerospace, Inc. 5 © 1/2019 CenTex Aerospace, Inc. “Making Aviation Better!” Phone: (254) 752-4290 | www.CENTEX.aero P.O.
