CHAPTER FOUR

A scan pattern is a means, or procedure, by which you can observe everything you need to see by

starting at one point, moving visually about the aircraft, checking all applicable items

systematically and thoroughly and completing the pattern at the starting point. A scan pattern

may be started anywhere, but it must be complete and continuous.

What we refer to as the integrated scan involves combining contact flying and flight instruments

through a systematic pattern. The task of scanning in contact flying (VMC) involves division of

attention between the external and internal environment, setting attitudes with the nose and

wings in relation to the horizon and cross-checking them against the instruments in the cockpit.

The following scan pattern is a workable example. Figure 4-2, Integrated Scan Patterns, on the

next page, gives a pictorial representation of two of the views-outside the cockpit and the

Attitude Gyro-that you will use to orient yourself in the air. Figure 4-2 will also be referred to in

discussing various basic maneuvers.

Outside the cockpit:

Attitude and area - Nose in proper relation to horizon and geographical references for

heading and position.

Area - Airspace between nose and left wing clear of hazards.

Attitude - Left wing in proper relation to horizon.

Inside the cockpit:

Attitude - Check wings level with RMI and correct nose position with the altimeter

and VSI.

Performance - Check airspeed indicator and power setting.

Outside the cockpit:

Attitude and area - Nose in proper relation to horizon and geographical references for

heading and position.

Attitude - Right wing in proper relation to horizon.

As a beginner, you may crosscheck rapidly by "looking" without knowing exactly what you are

looking for, but with increasing familiarity with the maneuvers and experience with the support

instruments, you will learn:

What to look for,

When to look for it, and

What response is required.

As proficiency increases, you will scan primarily from habit by adjusting your scanning rate and

sequence to the demands of the situation. The scan requirements will vary from maneuver to

maneuver, so initially the scanning process will seem new and somewhat unnatural. It cannot be

overemphasized, however, that your level of success in flight training will vary proportionately

with your ability to force yourself to develop and maintain a correct and expeditious scan pattern.
