Abstract
An attitude indicator provides a display which combines the motion of an aircraft symbol with that of a background/horizon symbol to achieve the best features of conventional "inside-out" and "outside-in" types of attitude displays. The present invention is featured in the provision of a cueing control circuitry which, in response to inputted pitch and bank attitude indicative signals, effects the positioning of at least one of the aircraft symbol and the horizon indicating symbol of an attitude indicator as a function of at least one of the magnitude and rate of change characteristics of pitch and bank attitude signals inputted thereto.
Claims7
In an attitude indicator instrument for an aircraft,
- an aircraft symbol positionable in accordance with pitch and bank attitudes of said aircraft,
- a horizon indicator positionable in accordance with pitch and bank attitudes of said aircraft;
- cueing control circuitry receiving inputs proportional to the experienced pitch and bank attitudes of said aircraft, said cueing control circuitry selectively effecting the positioning of both said aircraft symbol and said horizon indicator as a function of at least one of the magnitude and rate of change characteristics of at least one of the pitch and bank attitude signals applied to said cueing control circuitry.
