You are cruising under VFR when the passenger reports that the cabin door has inadvertently unlatched and opened in flight, causing minor yaw and buffeting. Referring to the POH emergency procedures flowchart for 'Inadvertent Cabin Door or Window Opening', what is the FIRST step indicated?

During a daytime VFR cross-country flight at 4,500 feet AGL, the alternator failure light illuminates and the ammeter shows a continuous discharge. Recycling the alternator switch has no effect, and battery voltage is steadily decreasing. The nearest suitable airport is 25 minutes flying time directly ahead at cruise speed. What is the MOST IMPORTANT action to take?

During cruise flight in a single-engine airplane, you detect an acrid electrical odor and observe thin smoke entering the cockpit from the instrument panel area. Engine instruments and performance are normal. What is the MOST APPROPRIATE first action?

While cruising on a clear VFR cross-country flight, you notice the attitude indicator precessing erratically and tumbling, followed shortly by the heading indicator doing the same. The vacuum gauge now reads zero. What is the BEST course of action?

A single-engine, reciprocating-engine-powered airplane experiences a partial power loss during cruise flight. A magneto check reveals the following: BOTH magnetos . . . . . 2,350 RPM smooth operation LEFT magneto . . . . . 2,150 RPM rough operation RIGHT magneto . . . . . 2,400 RPM smooth operation The MOST LIKELY cause of the power loss is
