Sustaining Aviator Performance During Extended Operational Flight

"Active simulation will be applied to the right PPC. To target this region for stimulation, the anode electrode will be placed on the subject using the 10-20 EEG system as reference location (Thair et al., 2017). Stimulation intensity for all conditions will be set to 2 mA, which was chosen based on previous studies that have compared 1 mA to 2 mA and found the higher intensity produced reliable changes to performance (e.g., Moos et al., 2012). Total time of active stimulation will be the same for each group (20 minutes). Delivery times of the stimulation will vary based on Group assignment:~Group A: During pre-flight brief/checklist, for 20 minutes. Group B: First delivered at 30 minutes into flight for 10 minutes, second delivered at 60 minutes into flight for 10 minutes."

"Sham simulation will be applied to the right PPC. To target this region for stimulation, the anode electrode will be placed on the subject using the 10-20 EEG system as reference location (Thair et al., 2017). Stimulation intensity for all conditions will be set to 2 mA, which was chosen based on previous studies that have compared 1 mA to 2 mA and found the higher intensity produced reliable changes to performance (e.g., Moos et al., 2012). Total time of active stimulation will be the same for each group (20 minutes). Sham stimulation will consist of active stimulation for 120s, including the ramping up to 2 mA and down to no stimulation. Delivery times of the stimulation will vary based on Group assignment:~Group A: During pre-flight brief/checklist, for 20 minutes. Group B: First delivered at 30 minutes into flight for 10 minutes, second delivered at 60 minutes into flight for 10 minutes."
