Procedure
Pilots were asked to rate the overall level of compensation required for a task using the following descriptors: not-a-factor, minimal, moderate, considerable, extensive, and maximum-tolerable. These descriptors were taken from the Cooper-Harper Handling Qualities Scale (ref. 53), and were thus familiar to all the test pilots. For analysis, these adjectives were given interval numerical values from –1 to 4, respectively.
Next, the pilots rated the motion fidelity according to the following three categories: (1) Low Fidelity—motion cueing differences from actual flight were noticeable and objectionable, (2) Medium Fidelity—motion cueing differences from actual flight were perceptible, but not objectionable, and (3) High Fidelity—motion cues were close to those of actual flight. These definitions were taken (and slightly modified) from Sinacori (ref. 44) (modification discussed later in sec. 4). For this experiment, pilots had to rely on recollection of their actual in-flight experience. These subjective ratings were given numerical values 0 to 2, respectively.
Finally, the pilots were asked to report whether they perceived any cockpit translational or rotational motion. A zero was assigned if they did not feel a particular motion. Each of the four configurations was flown four times in a random sequence by each pilot.
