An Evaluation of Four F-16 Vertical Velocity Indicator Configurations

Abstract

Four different Vertical Velocity Indicator (VVI) configurations/ mechanizations were evaluated in an F-16C simulator: (1) F-16C moving tape VVI, (2) electromechanical semicircular, moving pointer VVI, (3) liquid crystal, semicircular, moving pointer VVI and (4) same as 3 with a faster response time. Configurations 1, 2, and 3 had the same dampening characteristics as are currently used in the F-16C; configuration 4 was included to assess the impact of VVI dampening on pilot performance. Ten pilots flew a series of rate climbs/ descents and an Instrument Landing System approach and landing for each configuration. Pilot performance data showed a larger average pitch rate for the moving tape VVI, suggesting greater workload, and an improved ability to maintain a specified vertical velocity when using configuration 4. Subjective data showed that the moving tape was the least preferred of the four, especially for use in dynamic conditions.
