ABSTRACT:
A gyroscopic referenced electronically operated grade and slope attitude indicator enabling a heavy equipment operator to build a slope and/or grade by visual readout. It is a system using a gyro output to compute the grade and slope for display thereof on a dual steering bar indicator. An angle calibration along with cancelling switches allows an equipment operator a selection of slope and grade ratios to work to in a work approach making staking and restaking of a slope and/or grade unnecessary other than for a surveyed starting point with a toe-stake or its equivalent.
