SPL Knowledge Test 7

Two-cycle engine power and fuel economy can be greatly hindered when:

carburetor heat is not used at full throttle.

one-way pressure valves, or poppet valves, open when the pressure drops within the crankcase.

exhaust systems are installed that are not specifically tuned for an aviation engine.

What benefit does a digital attitude indicator provide?

It takes up less panel space.

The artificial horizon spans the entire width of the display.

It’s driven by the same vacuum system as a mechanical attitude indicator.

How often must the aircraft’s ELT be inspected?

Within 24 calendar months of the last inspection

Every two years

What is the main operating principle of a float-type carburetor?

Low pressure in the venturi of the carburetor forces fuel to flow through the main fuel jet and mix with intake air.

Fuel is pumped from the float chamber to the fuel discharge nozzle by an engine-drive fuel pump where it mixes with intake air.

Fuel is discharged into the airstream at a pressure well above atmospheric pressure causing it to vaporize.

incidence.

While operating in regions known for dust devils, such as the Southwest US, what is the recommended action a pilot should take when one is detected during flight operations at low altitudes?

Recognize and avoid the dust devil and be prepared to take evasive action if necessary.

Continue on the planned flight path, as dust devils are harmless and pose no risk to aircraft.

Immediately divert to the nearest airport and land as soon as possible to avoid the dust devil.

The wind at 5,000 feet AGL is southwesterly while the surface wind is southerly. This difference in direction is primarily due to
