For a vehicle having a specified normal attitude directly related to a specified normal movement axis of said vehicle, an attitude indicator comprising: a. a liquid crystal display having two concentric multisegmented circles, a first circumjacent the second, and a horizontal reference segment; b. means for operating said liquid crystal display such that when a defined arc on said second circle of segments is activated, the inactive segments of said second circle correspond substantially to the activated segments of said first circle, such that a complete circle is cooperatively defined; c. a plurality of segmented vertical bars for selective activation as a function of attitude of said vehicle around a lateral axis horizontal to the earth and perpendicular to said normal movement axis; and d. the relationship of said defined arc to said horizontal reference segment is a function of attitude of said vehicle around said normal movement axis.
