C172 Aircraft Systems Quiz

The time required for the Cessna 172R's oil pressure gauge to register after starting the engine in cold weather.

The minimum vertical distance between the propeller and the ground when the aircraft is parked.

The minimum turning radius from the center point of the aircraft to the tip of the outboard wing.

The maximum airspeed at which abrupt use of flight controls is prohibited, due to aerodynamic considerations.

The range of airspeeds on the Air Speed Indicator marked by a yellow arc, indicating a range of speeds requiring careful maneuvering.

The minimum acceptable oil pressure reading in the Cessna 172R.

The action to take if the voltmeter reading exceeds 31.5 volts in the Cessna 172R.

The potential consequences of an alternator failure in the Cessna 172R.

The Cessna 172 has air/oil strut shock absorbers on the nose gear and tubular spring shock absorbers on the main gear.

The best rate of climb speed for the Cessna 172 at sea level is 79 knots indicated airspeed (KIAS).

The standard temperature lapse rate is a decrease of 2 degrees Celsius for every 1000 feet increase in altitude.

The recommended starter duty cycle is 10 seconds on, 20 seconds off for three times, followed by a 10-minute cooling period.

During the first 50 hours of operation, the maximum power setting during cruise should be limited to 70%.

In a fixed pitch propeller engine, carburetor icing is indicated by a drop in RPM. In a constant speed propeller engine, it is indicated by a rise in manifold pressure.

To test the OAT/Voltmeter gauge, press and hold the select button for 20 seconds.

If the microphone key is held down for 33 seconds or more, the selected COM transmission is discontinued.

The Direction Indicating Gyro (DGI) should be periodically aligned with the magnetic compass to correct for the gradual drift that occurs due to precession, a natural tendency of gyroscopes to shift their axis of rotation.

The stall warning system in the Cessna 172 will sound 5-10 knots above the aircraft's stall speed, providing a critical warning to the pilot to avoid an aerodynamic stall.

The maximum speed permitted for opening the Cessna 172's windows is 85 knots. This is to prevent damage to the windows and ensure the safety of the occupants.

The maximum amount of time the Cessna 172 can safely operate with one fuel tank empty and the other tank full is 30 seconds. This ensures safe fuel distribution and prevents engine damage.

Each fuel tank in the Cessna 172 has 1.5 gallons of unusable fuel reserved at the bottom of the tank. This fuel cannot be accessed by the engine and is left behind.

The maximum oil pressure in the Cessna 172 engine is indicated by the lower end of the upper red arc on the gauge. This corresponds to 125 psi.

The recommended fuel for the Cessna 172 is 100LL aviation gasoline, which is blue in color.

For extended flight operations, the Cessna 172 requires a minimum of 5 quarts of engine oil. This ensures proper lubrication and engine performance.

The oil pressure gauge should read between 50 and 90 psi during operation.

The minimum safe oil pressure is 20 psi. If it drops below this, immediate action is required.

A red line at 115 psi indicates the maximum acceptable oil pressure. Higher pressure can damage the engine.

Before every flight, check fuel for contamination. Additionally, check after refueling.

When the ignition switch is briefly turned from 'BOTH' to 'LEFT', a significant loss of power indicates a problem with the left magneto.

When the ignition switch is briefly turned from 'BOTH' to 'RIGHT', a significant loss of power indicates a problem with the right magneto.

The Vertical Speed Indicator (VSI) shows the rate of climb or descent in feet per minute.

The engine-driven vacuum system provides suction to operate instruments like the direction indicator and attitude indicator.

Cessna 172R's maximum speed with the window open.

The minimum vertical distance between the propeller and the ground when the aircraft is parked.

Beyond this speed, abrupt use of flight controls is prohibited due to aerodynamic considerations.

The maximum acceptable pressure reading on the Cessna 172R's oil pressure gauge.

The amount of fuel that cannot be used in each tank of the Cessna 172R due to its design.

The maximum allowable weight of the Cessna 172R when loaded on the ground.

The time that the aircraft can glide with one fuel tank empty.

The color of 100LL (low-lead) aviation fuel.

It's the recommended limit for using the starter. This ensures proper cooling between cycles to avoid engine damage.

This speed provides a balance between climb performance and engine cooling.

During the first 50 hours of operation, it's best to limit engine power to 70% to promote proper break-in of the engine.

A partially open door can create an air leak, impacting the engine's ability to draw in air, hence power loss.

This switch allows you to toggle between viewing outside air temperature (OAT) and voltmeter readings.
