Approach and landing longitudinal flying qualities for large transports based on in-flight results

摘要

To address the dearth of flying qualities criteria for very large transport aircraft, a piloted, in-flight simulation experiment using the USAF Total In-Flight Simulator (TIFS) was undertaken. ^Configurations with various levels of short period frequency, acceleration sensitivity, and equivalent time delay were flown and evaluated by a number of pilots. ^The pilot ratings were used to appraise the performance of the Control Anticipation Parameter (CAP) criterion using the equivalent system methodology. ^The results indicated that for large transports, the Category C Level 1 CAP lower boundary could be raised slightly. ^The results also identified a multi-parameter correlation between CAP and time delay. ^When applied to the bandwidth criterion, the results indicated that the Category C Level 2 boundary could be relaxed. ^(Author)
