Chapter 14: Airport Operations › Collision Avoidance › Pilot Deviations (PDs)
Pilot Deviations (PDs) A pilot deviation (PD) is an action of a pilot that violates any Federal Aviation Regulation. While PDs should be avoided, the regulations do authorize deviations from a clearance in response to a traffic alert and collision ... avoidance system resolution advisory. You must notify ATC as soon as possible following a deviation. Pilot deviations can occur in several different ways. Airborne deviations result when a pilot strays from an assigned heading or altitude or from an instrument…

maintains a constant airspeed and pitch attitude, the altitude should remain constant. Two factors that cause the altitude to deviate are turbulence and momentary distractions. When a deviation occurs, a change in the pitch needs to be made ... attitude indicator. Small deviations require small corrections, while large deviations require larger corrections. Pilots should avoid making large corrections that result in rapid attitude changes, for this may lead to spatial disorientation. Smooth, timely corrections should be made to bring…

Figure 5-19. A compass correction card shows the deviation correction for any heading. The corrections for variation and deviation must be applied in the correct sequence as shown below starting from the true course desired. Step 1: Determine ... Course True Course (180°) ± Variation (+10°) = Magnetic Course (190°) The Magnetic Course (190°) is steered if there is no deviation error to be applied. The compass card must now be considered for the compass course of 190°. Step 2: Determine…

The navigation instrument could be a course deviation indicator (CDI), horizontal situation indicator (HSI), or a radio magnetic indicator (RMI). Each of these instruments indicates the course ... tuned VOR. Course Deviation Indicator (CDI) The CDI is found in most training aircraft. It consists of an omnibearing selector (OBS) sometimes referred to as the course selector, a CDI needle (left-right needle), and a TO/ FROM indicator…
