6JJ instrument pod, R22 Beta II. TOP ROW: Turn Coordinator, Altimeter, Attitude Indicator, Airspeed, Dual Tach. BOTTOM ROW: Vertical Speed, Magnetic Compass, Heading Indicator, Manifold Pressure. Warning annunciators run across the top. This is the layout and the distinctive Robinson contour - learn where your eyes go.
Three-pointer sensitive altimeter. Each number = 100 ft; each small tick = 20 ft. LONG thin hand = hundreds, SHORT wide hand = thousands, the small triangle-tip pointer = ten-thousands. Set local pressure in the Kollsman window (here 29.92). Calibrated to 20,000 ft. Shown reading about 1,500 ft.
Outer scale KNOTS, inner scale MPH (amber). Green arc, the normal operating range, begins at 50 KIAS. Red line is Vne 102 KIAS at sea level - Vne decreases with density altitude and weight, so the real never-exceed is often lower than the paint.
Two needles on one face: E = engine RPM (cyan), R = rotor RPM (orange), both in %. Power-on green arc 101-104%. Low-RPM horn and caution light at 97%. Rotor red lines: 90% low, 110% high; low caution band 60-70%. In powered flight the governor keeps both needles married together in the green.
Vertical speed in hundreds of feet per minute. Zero sits at the 9 o'clock. Each small tick = 100 fpm; the numbers 5/10/15/20 mean 500-2000 fpm. Up = climb, down = descent. It runs off a calibrated leak, so it lags a few seconds behind the real trend.
The card is graded every 30°. Numbers are the heading with the last zero dropped: 3 = 030°, 6 = 060°, 12 = 120°. Cardinals: N 360 / E 090 / S 180 / W 270. Small ticks every 5°. Your heading is under the orange lubber line at the top; the orange bug is a reminder you set.
Manifold pressure in inches of mercury. The R22 has no fixed red line - maximum MP is a calculated value read off the MAP limit chart (it changes with pressure altitude and temperature). Placard: DO NOT EXCEED MP TABLE LIMITS. The engine is derated to 124 HP continuous, 131 HP for up to 5 minutes.
