Title: Aircraft Flight Instrument
Inventor: SULLIVAN NEIL
IPC: G05D1/06
Filed: 1965-09-03
Abstract: 1,156,326. Aircraft instruments. SPERRY RAND Ltd. 26 Aug., 1966 [3 Sept., 1965], No. 37645/65. Addition to 1,071,882. Heading B7W. An aircraft flight instrument as disclosed and claimed in the parent Specification is improved or modified in that a glide-slope receiver 38 is furnished with a signal representing deviation from a required glide path during a " glideslope " mode of flight of the aircraft, a signal transmitted from said receiver accordingly being added to the signal # emitted by the " vertical gyro " 30 and the pitch-rate-ofchange signal produced by the " rate taker " to form a resultant signal, which is applied to the index 35 so that the aircraft can be directed down the required glide path. The " rate demand limiter " prevents unduly large signals being applied to the index. A diode 43 prevents the signal # from the accelerometer 31 being included in the aforesaid resultant signal during " height-holding " and " glide-slope " modes of flight, i.e. when the signal f has a negative sense. It is indicated that the diode may be replaced by its A.C. equivalent. Reversal of the signal f may automatically effect a change from a " glide-slope " mode of operation of the instrument to a " take-off " mode, which modes can be selected manually by switching means (not shown) and effect a suitable combination of signals at the index to accord with the mode of flight. Other modes of operation of the instrument that can be selected by the switching means are " climb out " and " maintaining constant height." When the " take-off " mode is selected and the rotation speed V R  is exceeded, the airspeed signal that is included in the signal applied to the index during the pretake-off ground-run is reduced continuously by a follow-up servomotor (not shown); and when the " climb-out " mode is selected, the servomotor is stopped to prevent further reduction of the airspeed signal and the index 35 indicates any deviation from an optimum relationship between acceleration and pitch angle, or attitude, the rate of climb of the aircraft being adjusted to effect a constant airspeed in accordance with the airspeed signal at the moment when the servomotor is stopped. The signal f may be rendered zero when the acceleration of the aircraft is other than zero, e.g. when the acceleration is small.
