First sign of Carburator icingDrop in engine RPM and drop in engine Manifold Pressure
During engine starting, if engine floodsMixture idle/cut off
Flap switch lever mechanical stops are provided at 10-20-30 degree position intervals.
Annunciator located above altimeter provides caution for:Fuel Flow
Red gauge in Oil pressure illuminates when pressure isBelow 20 PSI
Alternator must be switched off manually if voltage indicates beyond:31.5 volts. But restart only when on ground
How much time do you wait for oil pressure gauge to read in very cold conditions, after starting the engine60 seconds
How to avoid inadvertent icingTurn back or change altitude
Maximum altimeter and airspeed variation from normal is30 feet and 4 knots
Preflight check of the Pitot heaterPitot heater is warm to touch within 30 seconds of battery and gradually when the Pitot heat switches ON
OIL Operating limitsNot less than 4 quarts. For longer flights upto 8 quarts
How to gauge the RPM functioning?RPM drop should NOT exceed more than 150 RPM on either magneto (Left and Right checking). And it should not be more than50 RPM differential between L & R magento checks.
How to perform Oil Pressure Check?After starting the engine, Oil pressure should be within the Green marking ARCS within 30 SECONDS in summer and within 60 SECONDS in very cold winter
