摘要: |
Pilots of vertical landing vehicles face numerous control challenges which often involve the loss of outside visual perceptual cues or the control of flight parameters within tight constraints. These challenges are often associated with a high mental workload, therefore, a precision landing aid that addresses and helps to mitigate these challenges, and reduce mental workload is needed. To address this need, a cognitive task analysis identified specific situation awareness requirements for the design of a vertical landing aid in order to reduce the mental steps required during a vertical landing. From these requirements, a new vertical landing decision aid, known as the Vertical Altitude and Velocity Indicator (VAVI) was designed, which displays altitude and vertical speed information in an integrated form including the display of flight parameter safety constraints. The display instrument takes advantage of direct-perception interaction by leveraging ecological perception and emergent features to provide quick perception and comprehension of critical flight parameters in an integrated fashion. |
