Additionally, the alternatives for proposed multifunction display (MFD) symbologies associated with the COMM/NAV Block Upgrade for the UH-IN were evaluated. A survey was administered to 43 LJH-IN operational pilots from both east and west coast squadrons. Pilots were asked to rate instruments and devices currently included on the instrument panel on three factors: Criticality, Frequency of Use, and Satisfaction with Display. The top ten and bottom ten instruments were identified for each of these three factors; 20 instruments rated high on all three factors while 10 rated low on all three. Several candidates for redesign were identified. Proposed multifunction display symbol sets from the Naval Air Warfare Center Aircraft Division, Warminster (NAWCADWAR), and MIL-STD-1295 (Proposed) were also assessed. Respondents rated symbols for (1) heading scale, present heading, and NAV steering bug (a pointer); (2) airspeed and present airspeed; (3) vertical velocity; (4) attitude, horizon, pitch angle, and aircraft reference; (5) altitude scale, present altitude, and high/low altitude warning; (6) torque; and (7) bank of roll scale, and slip.
