  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…

  Chapter 7: Ground Reference Maneuvers › Drift and Ground Track Control › Constant Radius During Turning Flight

  Figure 7-2. Effect of wind during a turn. For a given true airspeed, the radius of turn in the air varies proportionally with the bank angle. To maintain a constant radius over the ground, the bank angle used ... knots (for this discussion, assume true, calibrated, and indicated airspeed are all the same). If the pilot starts a turn using a 45° bank angle, the turn radius over the ground at that moment is approximately 890 feet…

  Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors in Steep Turns

  Load Factors in Steep Turns At a constant altitude, during a coordinated turn in any aircraft, the load factor is the result of two forces: centrifugal force and weight. [Figure 5-52] For any given bank angle, the ROT varies ... centrifugal force, allowing the load factor to remain the same. Figure 5-52. Two forces cause load factor during turns. Figure 5-53 reveals an important fact about turns—the load factor increases at a terrific rate after a bank…

  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…

  Chapter 3: Basic Flight Maneuvers › Level Turns › Turn Radius

  Turn Radius To understand the relationship between airspeed, bank, and radius of turn, it should be noted that the rate of turn at any given true airspeed depends on the horizontal lift component. The horizontal lift component varies in proportion ... amount of bank. Therefore, the rate of turn at a given airspeed increases as the angle of bank is increased. On the other hand, when a turn is made at a higher airspeed at a given bank angle, the inertia…

  Chapter 3: Basic Flight Maneuvers › Level Turns

  throttle provides thrust, which may be used for airspeed control and to vary the radius of the turn. ⦁ The pilot uses the rudder to offset any adverse yaw developed by wing’s differential lift and the engine/propeller. The rudder does ... turn the airplane. The rudder is used to maintain coordinated flight. For purposes of this discussion, turns are divided into three classes: shallow, medium, and steep. ⦁ Shallow turns—bank angle is approximately 20° or less. This shallow bank is such…
