This paper describes the method developed in 1982 to certificate the BAe 146 for operations by a minimum crew of two pilots to the requirements of JAR 25.1523. The method was based primarily on subjective assessment of workload but employed objective data to support that assessment. All the data were collected from one flying phase and no flight or ground simulator assessments were performed, neither were the results correlated with any previous evaluation. In this respect, the evaluation of the BAe 146 was unique amongst civil workload certification programmes. The flight evaluation was conducted as a mini-airline exercise similar to that done by other aircraft manufacturers. Three teams of two pilots flew consecutive three day intensive flight schedules around a circuit of 3 major European airfields, London-Heathrow, Paris-Charles de Gaulle, Amsterdam-Schippol, with crew duty hours on some days considerably in excess of those normally allowed for passenger carrying operations. The flight schedules called for multiple legs in a high density air traffic environment, and thus the evaluation was concentrated upon the high workload phases of airline operation. Additionally, operations with inoperative items from the Minimum Equipment List in conjunction with in-flight failure conditions were assessed. Deliberate in-flight failures or dispatch inoperative items were not simulated on the first day of each teams participation in the valuation, but those unplanned events that occurred were logged.
