Airplane Instruments, Engines and Systems

an aircraft is accelerated while on an east or west heading.

Only in straight-and-level unaccelerated flight.

magnetic fields within the aircraft distorting the lines of magnetic force.

correctly when on a north or south heading.

a right turn is entered from a north heading

the aircraft is decelerated while on a west heading.

a left turn is entered from a north heading.

Airspeed indicator.

1 and 2 only.

The vertical distance of the aircraft above the surface.

The vertical distance of the aircraft above sea level.

The pressure altitude corrected for nonstandard temperature.

At standard temperature.

When at sea level under standard conditions.

When standard atmospheric conditions exist.

The altitude indicated when the barometric pressure scale is set to 29.92.

true altitude at field elevation.

700-foot increase in indicated altitude.

Altimeter will indicate 150 feet lower.

lower than the actual altitude above sea level.

higher than the actual altitude above sea level.

Air temperature warmer than standard.

In colder than standard air temperature.

Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.

miniature airplane to the horizon bar.

By the relationship of the miniature airplane (C) to the deflected horizon bar (B).

movement of the aircraft about the yaw and roll axes.

periodically realigned with the magnetic compass as the gyro precesses.

the oil level being too low.

cause loss of power, excessive oil consumption, and possible permanent internal engine damage.

the circulation of lubricating oil.

too much power and with the mixture set too lean.

Reduce rate of climb and increase airspeed.

Enrich the fuel mixture.

The throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates engine RPM.

avoid high manifold pressure settings with low RPM.

Permits the pilot to select the blade angle for the most efficient performance.

improved engine performance.

more susceptible to icing.

difference in air pressure at the venturi throat and the air inlet.

loss of RPM.

a decrease in RPM and then a gradual increase in RPM.

Temperature between 20 and 70°F and high humidity.

high as 70°F and the relative humidity is high.

decrease engine performance.

enrich the fuel/air mixture.

The fuel/air mixture becomes richer.

Check the results obtained with a leaner setting of the mixture.

decrease the fuel flow in order to compensate for decreased air density.

The fuel/air mixture may become excessively lean.

the unburned charge in the cylinders explodes instead of burning normally.

lower the nose slightly to increase airspeed.

detonation.

pre-ignition.

The next higher octane aviation gas.

prevent moisture condensation by eliminating airspace in the tanks.

In the event engine-driven fuel pump fails.

Using fuel that has a lower-than-specified fuel rating.

Adjust for proper RPM and check for desired indications on the engine gauges.
