Where Should We Look?
? SD Complex with Multi-System Interaction? Vestibular/Somatosensory: Mechanical? Visual: Cognitive
? Recognition and Recovery Requires Conscious Attention
?Most Contributors are Cognitive (Distraction, Task-Saturation, Channelized Attention)
? If Looking to Prevent (Using Human-Based Intervention)-Treat SD as a Cognitive Phenomenon
17
?Can We Eliminate the SD Environment??Mitigation Strategies:
?Hardware Upgrades (AGCAS, CAPT Rupert’s Vest, HUD/HMD Symbologies, Etc)?Expense??Long Term
? Liveware Upgrades (Training)?Cost v. Benefit??Short to Mid Term?Stop Gap until Hardware Upgrades On-Line?
What Can We Do?
18
?How Do We TRAIN Flyers for SD??Didactic?Few Get ASD Demonstrator Rides?Effective?
?What do We Need to Capture??How “Real” Do We Have to Get to
Capture SD Inducing Scenarios??How Much Acceleration Do We Need??Can We Achieve Effect with Visual
Mission Task Trainers?
19
Bottom Line
?SD Costs the USAF a Lot of Lives (and Money)?SD is Always a Threat (Unless We can Change
the Environment)?SD Recognition and Recovery Requires
Conscious Intervention ?Training???????Hardware Solutions?????
How Much are We willing to Pay?
