wings overlap the horizon bar when the aircraft is in straight-and-level cruising flight. The pitch and bank limits of an attitude indicator depend upon the make and model of the instrument. Some attitude indicators have limits ... from 60° to 70°. For those attitude indicators that display only pitch information of +/- 25° vertically, the instrument could "peg" (stop) and remain at this pitch indication until the pitch no longer exceeds limitation or "tumble" and provide erroneous pitch…

merely keep the aircraft stalled. It is a characteristic of T-tail aircraft to pitch up viciously when stalled in extreme nose-high attitudes, making recovery difficult or violent. The stick pusher inhibits this type of stall. At approximately ... above stall speed, pre-programmed stick forces automatically move the stick forward, preventing the stall from developing. A G-limiter may also be incorporated into the system to prevent the pitch down generated by the stick pusher from imposing excessive…

wing’s surface, brought on by exceeding the critical angle of attack. A stall can occur at any pitch attitude or airspeed. Standard atmosphere. At sea level, the standard atmosphere consists of a barometric pressure of 29.92 inches of mercury ... aircraft, the standard rate turn is 1½° per second (360° in 4 minutes).

some heading indicators found in light aircraft, the limits are approximately 55° of pitch and 55° of bank. When either of these attitude limits is exceeded, the instrument “tumbles” Figure 8-30. Driven by signals from a flux valve…

aircraft is concentrated. If the aircraft were supported at its exact CG, it would balance in any attitude. It will be noted that CG is of major importance in an aircraft, for its position has a great bearing upon stability ... natural tendency for the aircraft to want to pitch nose down. If the CP is forward of the CG, a nose up pitching moment is created. Therefore, designers fix the aft limit of the CG forward…

turn direction and quality (coordination), and also serve as a backup source of bank information in the event an attitude indicator fails. Coordination is achieved by referring to the inclinometer, which consists of a liquid-filled curved tube with ... turn-and-slip indicator rotates in the vertical plane corresponding to the aircraft’s longitudinal axis. A single gimbal limits the planes in which the gyro can tilt, and a spring works to maintain a center position. Because of precession…
