SITUATIONAL AWARENESS MAKING USE OF DR PRINCIPLES AND OTHER

SKILLS

INTRODUCTION

Up to this point in Instruments we dealt with a "perfect" situation. It is assumed that every piece

of equipment in the aircraft functions properly (i.e., TACAN #2 needle and DME will always be

available). Fortunately, this is the case most of the time; however, there are times when even the

best aircraft equipment no longer functions. This may be due to some problem with the aircraft

or failure of the local NAVAID.

As the NFO on board, it is up to you and the pilot to keep track of where the airplane is going,

where it is, and how it gets to its destination. This requires you to fall back on some

fundamentals in order to get to your destination. It may be that the only information you have is

heading, airspeed, and time.

This section covers how you can use the wind triangle, a fundamental of Dead Reckoning (DR),

and logical thought processes to maintain course in flight and predict aircraft position.

LESSON TOPIC LEARNING OBJECTIVES

TERMINAL OBJECTIVE

C. Navigate an aircraft via visual references and navigation instruments with the assistance of

a flight instructor.

ENABLING OBJECTIVE

C.11. Derive aircraft heading using dead reckoning techniques, a given course (5).

C.11.1. Given any two components of the wind triangle, derive the third component.

C.11.2. Predict aircraft position based on speed, distance, and heading.

C.11.3. Using in-flight derived winds, determine appropriate heading to maintain a

desired course while compensating for wind effect.
