  • Chapter 7, Section I: Airplane Basic Flight Maneuvers › Turns › Standard Rate Turns

    Turns Standard Rate Turns A standard rate turn is one in which the pilot will do a complete 360° circle in 2 minutes or 3 degrees per second. A standard rate turn, although always 3 degrees per second, requires higher ... angles of bank as airspeed increases. To enter a standard rate level turn, apply coordinated aileron and rudder pressures in the desired direction of turn. Pilots commonly roll into turns at a much too rapid rate. During initial training…

  • Chapter 7, Section II: Airplane Basic Flight Maneuvers › Turns › Establishing A Standard Rate Turn

    Establishing A Standard Rate Turn In order to initiate a standard rate turn, approximate the bank angle and then establish that bank angle on the attitude indicator. A rule of thumb to determine the approximate angle of bank ... bank is required (100/10 = 10 + 5 = 15); at 120 knots, approximately 18° of bank is needed for a standard-rate turn. Cross-check the turn rate indicator, located on the HSI, to determine if that bank angle is sufficient…

  • Chapter 4: Aerodynamic Factors › Atmosphere › International Standard Atmosphere (ISA)

    International Standard Atmosphere (ISA) The International Civil Aviation Organization (ICAO) established the ICAO Standard Atmosphere as a way of creating an international standard for reference and performance computations. Instrument indications and aircraft performance specifications are derived using this standard ... reference. Because the standard atmosphere is a derived set of conditions that rarely exist in reality, pilots need to understand how deviations from the standard affect both instrument indications and aircraft performance. In the standard atmosphere, sea level pressure…

  • Chapter 4: Principles of Flight › Pressure › Atmospheric Pressure

    changing atmospheric pressure, a standard reference was developed. The standard atmosphere at sea level is a surface temperature of 59 °F or 15 °C and a surface pressure of 29.92 inches of mercury ("Hg) or 1,013.2 mb. [Figure ... standard temperature lapse rate is when the temperature decreases at the rate of approximately 3.5 °F or 2 °C per thousand feet up to 36,000 feet, which is approximately –65 °F or –55 °C. Above this point, the temperature…

    power is increased. Additional lift is generated causing the nose of the aircraft to pitch up. Turns Standard Rate Turns The previous sections have addressed flying straight-and-level as well as climbs and descents. However, attitude instrument flying ... departure airport to destination airport without any radical flight maneuvers. A turn to specific heading should be made at standard rate. Standard rate is defined as a turning rate of 3 degrees per second, which yields a complete 360° turn…

  • Chapter 7, Section I: Airplane Basic Flight Maneuvers › Basic Instrument Flight Patterns › Standard 45° Procedure Turn

    Standard 45° Procedure Turn 1. Start timing at point A (usually identified on approach procedures by a fix). For example, fly outbound on a heading of 360° for a given time (2 minutes, in this example). [Figure ... After flying outbound for 2 minutes (point B), turn left 45° to a heading of 315° using a standard rate turn. After roll-out and stabilizing, fly this new heading of 315° for 40 seconds and the aircraft will…
