T-34C CONTACT
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.
1.
Outside the cockpit:
a.
Attitude and area - Nose in proper relation to horizon and geographical references for
heading and position.
b.
Area - Airspace between nose and left wing clear of hazards.
c.
Attitude - Left wing in proper relation to horizon.
2.
Inside the cockpit:
a.
Attitude - Check wings level with RMI and correct nose position with the altimeter
and VSI.
b.
Performance - Check airspeed indicator and power setting.
3.
Outside the cockpit:
a.
Attitude and area - Nose in proper relation to horizon and geographical references for
heading and position.
b.
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.
