Abstract:
1. An aircraft attitude system comprising: an instrument face having a bank angle scale, a bank status indicator, a pitch angle scale and a pitch status indicator; the bank angle scale being fixed in position relative to the instrument face and being operative to present increments of bank angle of an aircraft; the bank status indicator being operative to move relative to the bank angle scale such that a current aircraft bank angle is indicated; the pitch angle scale being in a vertical orientation relative to the instrument face and being operative to present increments of pitch angle of an aircraft; the pitch status indicator being operative to move relative to the pitch angle scale such that a current aircraft pitch angle is indicated; wherein the pitch status indicator comprises a pitch deviation guide, the pitch deviation guide being configured as an extendable tape originating in a vicinity of 0° pitch angle on the pitch angle scale and terminating in a vicinity of the pitch status indicator such that a length of the pitch deviation guide changes responsive to changes in aircraft pitch.
