  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 ... proportional to groundspeed. For example, an airplane is in the downwind position at 100 knots groundspeed. In this example, the wind is 10 knots, meaning that the airplane has an airspeed of 90 knots (for this discussion, assume true, calibrated…

  airplane’s inherent overbanking tendency 3. Significant loss of the vertical component of lift when the wings are steeply banked 4. Substantial pitch control pressures 5. The need for increased additional power to maintain altitude at a constant airspeed during ... turn As discussed in previous chapters, when banking an airplane for a level turn, the total lift divides into vertical and horizontal components of lift. In order to maintain altitude at a constant airspeed, the pilot increases the angle…

  important fact for pilots to remember when making constant altitude turns is that the vertical component of lift must be equal to the weight to maintain altitude. At a given airspeed, the rate at which an aircraft turns depends upon ... horizontal component of lift. It is found that the horizontal component of lift is proportional to the angle of bank—that is, it increases or decreases respectively as the angle of bank increases or decreases. As the angle of bank…

  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…

  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 ... with the airspeed—the higher the speed, the slower the ROT. This compensates for added centrifugal force, allowing the load factor to remain the same. Figure 5-52. Two forces cause load factor during turns. Figure 5-53 reveals…

  Chapter 5: Aerodynamics of Flight › Load Factors › Radius of Turn

  Turn The radius of turn is directly linked to the ROT, which explained earlier is a function of both bank angle and airspeed. If the bank angle is held constant and the airspeed is increased, the radius of the turn ... changes (increases). A higher airspeed causes the aircraft to travel through a longer Figure 5-57.
