427:(the "dew point spread"), as well as visible signs of moisture in the atmosphere. Icing can lead to loss of engine power, and if not corrected, total shutdown of the engine. A carburetor heat control is used to supply heated air to the carburetor; this can prevent or cure icing, but also causes a reduction in engine power output because hot air is less dense, enriching the fuel-air mixture. The carburetor heat control is a simple plunger-type control mounted on the center console near the collective pitch control lever. Pulling the control up slides a gate valve near the carburetor that admits warm air from a scoop on the exhaust system. The R22 employs a carburetor air temperature gauge, marked to indicate temperatures conducive to icing. The Beta II version of the R22 also includes a "carburetor heat assist", which automatically applies carburetor heat when the collective lever is lowered below a certain point. When icing conditions are present, carburetor heat is required to prevent icing around the butterfly valve from the pressure drop at that point. As the carburetor air temperature (CAT) indicator does not read correctly below 18

circuits and locking the clutch/drive system at take-off tension. The problem was ultimately solved by replacing the four individual v-belts with two dual v-belts. The upper, driven sheave is mounted on the main/tail rotor drive shaft incorporating flexible couplings, and is raised and lowered relative to the engine-mounted, driving sheave by means of a belt tension actuator. During shutdown, the actuator is used to lower the upper sheave to loosen the drive belts. For startup, the engine is started with the belts loose, allowing the engine to run without spinning the rotor system. Immediately after engine start, the clutch switch located in the cockpit is closed by the pilot, powering the actuator to slowly raise the upper sheave to flight position, which tightens the belts. The actuator is thereafter controlled by pressure-sensing column springs, automatically maintaining proper belt tension during flight as the belts wear and stretch. The shaft on which the upper sheave is mounted drives both the main and tail rotors; the main gear box delivers power to the main rotor shaft through a set of

low-altitude hover with two people on board. The R22 Beta added an engine speed governor (optional), rotor brake, and auxiliary fuel tank (optional). The battery was moved from below the instrument cluster to the engine compartment for better balance. The R22 has been offered as an instrument trainer version, with optional fixed floats as the R22 Mariner, and other special configurations for police work, electronic news gathering, and so on. The R22 Beta II received a larger
Lycoming O-360 engine derated for sea-level operation. It allows greater altitudes for hovering in and out of ground effect (HIGE/HOGE).

landing. The teetering bar has a hand grip on both sides that hangs down between the pilots' legs. Thus, if teetered to the right, the right-side pilot would be flying and the left grip would be about 12 inches above the left pilot's lap. R22 flight instructors quickly learn how to fly with their hand in the air. The left part of the bar, left collective control, and left tail-rotor pedals can be removed if the left-seat occupant is not going to fly such as a non-rated pilot. A floor-mounted, foot-activated push-to-talk switch facilitates intercom communications for the left-seat occupant, although some later models may be equipped with a voice-activated intercom system.
343:, which works to maintain engine speed within normal operating limits (between 97 and 104%); the governor is active when the engine is running only above 80% and is most effective in normal flight conditions. Robinson introduced the governor to ease pilot workload and to reduce instances of main rotor stall due to low rotor RPM. The governor can be switched on or off with a toggle switch located at the end of the pilot's collective pitch control. When the governor is not engaged, a yellow caution light glows on the instrument panel.

Instructors transitioning from larger helicopters to the new, smaller R22. After the introduction of the Robinson Pilot Safety Course, the rate of fatal R22 accidents declined from 3.7 per 100,000 flight hours in 1983 to 0.97 per 100,000 flight hours for the 12 months preceding July 1995. Robinson's statistics show the rate of fatal R22 accidents per 100,000 flight hours fell from 6.0 in 1982 to 0.7 in 1997. As of 2012, more than 17,000 students have gone through the course.
