FLIGHT INSTRUMENTS

Think of your instrument panel as your window to the outside world. Through instruments, you

may readily visualize the attitude of the aircraft, interpret the power output of the engine, and

check the resulting flight performance. From this overall picture, you make continual

adjustments in power and attitude, supported by trim, in order to achieve the desired

performance. However, before this picture becomes clear and complete, you must have a

thorough knowledge of the instruments; not only their contribution to the overall picture, but

also, each instrument's activating source.

Attitude Indicator Attitude Gyro/Vertical Gyro Indicator (VGI)

The attitude gyro (Figure 12) provides the pilot with constant visual indication of

aircraft pitch and roll. A complete description of this system is found in NATOPS.

The attitude gyro is your primary attitude instrument. There are several obvious

reasons for this, which must be emphasized:

It is the only direct reading instrument. In other words, it shows exactly the

amount of bank or nose pitch being utilized.

ii.

It shows attitude change immediately. There is no lag in this instrument.
