  Chapter 8: Flight Instruments › Gyroscopic Flight Instruments › Turn Coordinator

  Turn Coordinator The gimbal in the turn coordinator is canted; therefore, its gyro can sense both rate of roll and rate of turn. Since turn coordinators are more prevalent in training aircraft, this discussion concentrates on that instrument. When rolling ... into or out of a turn, the miniature aircraft banks in the direction the aircraft is rolled. A rapid roll rate causes the miniature aircraft to bank more steeply than a slow roll rate. The turn coordinator can be used…

  basic truth about turns is that when the aircraft banks, lift acts inward toward the center of the turn, perpendicular to the lateral axis as well as upward. Newton’s First Law of Motion, the Law of Inertia, states that ... object at rest or moving in a straight line remains at rest or continues to move in a straight line until acted on by some other force. An aircraft, like any moving object, requires a sideward force to make…

  Chapter 8: Flight Instruments › Gyroscopic Flight Instruments › Turn-and-Slip Indicator

  Turn Indicators Aircraft use two types of turn indicators: turn-and-slip indicators and turn coordinators. Because of the way the gyro is mounted, the turn-and-slip indicator shows only the rate of turn in degrees per second ... turn coordinator is mounted at an angle, or canted, so it can initially show roll rate. When the roll stabilizes, it indicates rate of turn. Both instruments indicate turn direction and quality (coordination), and also serve as a backup source…

  climb. For example, a 10° climb would require thrust to equal drag plus 17 percent of weight. To climb straight up would require thrust to equal all of weight and drag. Therefore, the angle of climb for climb performance ... aircraft is no longer able to climb. At this point, the aircraft has reached its “absolute ceiling.” Forces in Descents As in climbs, the forces that act on the aircraft go through definite changes when a descent is entered from…

  Climbing and Descending Turns For climbing and descending turns, the techniques described previously for straight climbs, descents, and standard rate turns are combined. For practice, simultaneously turn and start the climb or descent. The primary and supporting instruments ... stabilized constant airspeed left climbing turn are illustrated in Figure 8-15. The level off from a climbing or descending turn is the same as the level off from a straight climb or descent. To return to straight-and-level…
