When should you apply carb heat?

visible moisture, carb temp in yellow arc, or MAP below 18’’

What are the wind limitations?

surface winds above 25 including gusts, gust spread exceeding 15, and continued flight in moderate-extreme turbulence

What category of pilots do the wind limitations apply to?

Pilots with less than 200 hours in helicopters, 50 of which being in the R22

define land immediately and land as soon as practical

land immediately: land on the nearest clear area. Be prepared to enter an autorotation if required.

land as soon as practical: landing is at pilots discretion based on nature of the problem and available landing areas.

What is Vy?

53 KIAS

What is maximum range?

83 KIAS

Why do we keep the left door on when possible?

To prevent loose objects striking the tail rotor

What are the most likely temperature ranges for carb ice to occur?

25-86F, dew point spread less than 27F

Should you fly over assemblies of people?

No. If unavoidable, fly as high as practical, preferably at least 2000’ AGL

When does blade slap occur?

shallow, high speed descents and turns

What techniques should you use when overflying noise abatement areas?

Remain always above 500’ AGL and preferably above 1000’ AGL. Vary your flight path. Select the least noise-sensitive route.

What is Vh versus Vne?

Vh is the maximum continuous power speed, and Vne is the structural safety limit

stainless steel

What instruments depend on the pitot-static system?

Airspeed indicator, altimeter, and vertical speed indicator

Where does the engine tach reading come from?

The right magneto

Where does the rotor tach reading come from?

Magnetic senders at the main gearbox drive yoke.

How does the clock and tachometers stay running with the battery switch off?

There is a bypass circuit that continues to provide power to the clock and tachs as long as the clutch is engaged.

What provides the readings for the low oil pressure and low fuel lights?

An independent sensor in either system. They are not dependent on the gauges.

How do the main and tail rotor chip sensors work?

The detectors are magnetic devices in the drain plug of each gearbox. When metallic particles contact the magnet, it closes the circuit, illuminating the caution light.

What is an EMU?

Engine Monitoring Unit. Its a digital recording device in the RPM governor control box and monitors engine and rotor status for exceedances for the purpose of maintenance.
