This research aimed to identify factors related to the use of Head-Up Display (HUD) which influence the performance of pilots in procedures ILS CAT I, with low limits of visibility and height decision. To achieve this goal, it was developed an experiment in a flight simulator and interviews with pilots involved in the training with EMB-190 aircraft of an airline company, and also in a squadron of the Air Force responsible for authorities transportation. The experiments in the simulator indicated that in manual flight the HUD reduces the lateral error, the vertical error and the speed variances. From the analysis of positions of the pilots interviews, it was identified that the most valued feature in the HUD is the fact of having access to essential data such as: attitude, energy (velocity and acceleration), altitude and course deviations at the same time when looking outside toward the displacement of the aircraft. This HUD interface feature improves the quality of pilotage and reduces the time for tracking data, facilitating the transition from the instruments to the visual external references. The results led to conclude that the use of HUD enables operations with low limits of ceiling and visibility by increasing the accuracy of the trajectory and the pilot situational awareness.
