6.3  Performance prediction.  SAE Truck Ability Prediction Procedure computations and computations for low speed and maximum geared speed will be required by the contract.  The SAE Work Sheet Item 1 should include vehicle model number, engine model number and

vehicle class.  Unless other conditions are cited in the contract, computations should be made for normal atmospheric pressure, normal ambient air temperature, and still dry air.  The factors to be used in predicting truck ability (see 3.3.1.1) are established as follows for the corresponding
