Book Description
A two-phase experiment was conducted to explore the effects of data-link weather displays upon pilot decision performance. The experiment was conducted with 49 instrument rated pilots who were divided into four groups and placed in a simulator with a realistic flight scenario involving weather containing convective activity. The inflight weather display depicted NEXRAD images, with graphical and textual METARs over a moving map display. The experiment explored the effect of weather information, ownship position symbology and NEXRAD cell size resolution. The phase-two experiment compared two groups using the data-linked weather display with ownship position symbology. These groups were compared to the phase-one group that did not have ownship position symbology. The phase-two pilots were presented with either large NEXRAD cell size (8 km) or small cell size (4 km). Observations noted that the introduction of ownship symbology did not appear to significantly impact the decision making process, however, the introduction of ownship did reduce workload. Additionally, NEXRAD cell size resolution did appear to influence the tactical decision making process.

Book Description
The present study investigated effects of weather related factors on the performance of pilots under free flight. A weather scenario was defined by a combination of precipitation factors (light rain, moderate rain, and heavy rain or snow), visibility (1,4,8 miles), wind conditions (light, medium, or heavy), cloud ceiling (800ft. below, 1800ft above, and 4000ft horizontal). The performance of the aircraft self-separation was evaluated in terms of detection accuracy and detection times for student- and commercial (expert) pilots. Overall, the results obtained from a behavioral analysis showed that in general, the ability to recognize intruder aircraft conflict incidents, followed by the ability to acquire the spatial location of the intruder aircraft relative to ownership aircraft were judged to be the major cognitive tasks as perceived by the participants during self-separation. Further, the participants rarely used cockpit display of traffic information (CDTI) during conflict management related to aircraft separation, but used CDTI highly during decision-making tasks. In all weather scenarios, there were remarkable differences between expert and student pilots in detection times. In summary, weather scenarios were observed to affect intruder aircraft detection performance accuracies. There was interaction effects between weather Scenario-1 and Scenario-2 for climbing task data generated by both expert- and student- pilots at high traffic density. Scenario-3 weather condition provided an opportunity for poor detection accuracy as well as detection time increase. This may be attributed to low visibility. The intruder aircraft detection times were not affected by the weather conditions during climbing and descending tasks. The decision of pilots to fly into certain weather condition was dependent in part on the warning distance to the location of the weather. When pilots were warned of the weather conditions, they were more likely to fly their aircraft into it, but mos...

Book Description
This SAE Aerospace Recommended Practice (ARP) addresses the information content for the electronic presentation of data linked weather Meteorological (MET) information used in the cockpit. It defines guidelines for the electronic presentation of MET information (including text, graphics, textures, icons, and symbology) to the flight crew.This ARP is applicable to certified equipment for the electronic display (whether installed or portable) of MET information in the cockpit. This ARP also provides a set of symbols that illustrate the depiction of data linked MET information on flight deck display systems such as Navigation Displays, Multi-function Displays, and Electronic Flight Bags. These recommendations complement standard symbology guidelines for airborne applications already in existence (see reference section for applicable documents). Weather data, information, and products are widely available today to the public as well as to the aviation community. Weather information has been provided to the cockpits of General Aviation (GA) users for several years and is now being introduced into the cockpit of commercial aircraft. Guidelines for the standardization of this information are needed to ensure the appropriate display of weather information in the cockpit to adequately address issues of workload, meteorological situation awareness, training, and information management.
