2 Legacy from Manned AviaHon Good Safety Professionalism Bad Slow, reachve regulatory process Flying economy High entry price Ugly High Human Error rates!! 2

3 Human Performance In RPAS AviaHon accident stats Although percentages vary, most would agree that somewhere between 60-80% of aviahon accidents are due, at least in part, to human error (Shappell & Wiegmann, 1996). RPAS accident stats About 100 Predator Accidents from ; 51% mishaps involving crewmember acts (Tvaryanas, 2005) Tvaryanas (2004) on mishap epidemiology states that Human System Interface (HSI) issues are discussed in 89% of the Predator accidents and are cited as a causal factor in 44% of those accidents. Mishaps in the first few years were o6en abributed to equipment failures, while mishaps in the last three years were predominantly operator error (Nullmyer, et al, 2007) As drone use has taken off, human error remains a leading cause of unmanned aerial vehicle crashes. (Popular Science, 2013). Why? How can we do beber?

4 Current UAV Operator Interface Issues Lengthy process to handoff vehicle control Multiple screens require significant mental integration to obtain mission/ battlespace awareness Too many inputs required to implement commands (e.g., 22 key strokes to turn on the auto pilot ) Poor ergonomics Highly loaded visual channel Add-on systems (i.e., Falconview) provide needed functionality but cannot interface directly with core GCS Varying methods to input data Limited alert cues to warnings where messages can be hidden Visualization is poor and perpetuates mistakes Lack of system feedback regarding task completion Narrow visual field of view Extra workspace required Multiple keyboard/input devices required Multiple separate comm devices Numerous alphanumeric status displays Non-intuitive multilayered menus No decision aiding /support technology Cleared for Public Release 88ABW

8 Is it Pilot Error? A lible background: April 26, 2006 (NTSB, 2006) Predator B with two side- by- side consoles Power lever operates in two modes Events: Sensor controls Iris, middle posihon locks Pilot engine control, middle posihon shuts off fuel Pilot s console locked- up Pilot took over sensor console Did NOT perform transfer checklist Power lever was in middle posihon (now fuel shut off) Warning tone (but all the same; thought to be temp lost link) 3:50 a.m., A/C impacts the ground near Nogales, AZ 8

9 UAS Pilot Quotes This thing s kind of climbing like a pig. Climb, you pig.... Boy, this is going to be <ght.... Okay, interes<ng. We are falling out of the sky. UnidenHfied pilot of a Predator that crashed near Creech Air Force Base in Nevada on May 13, Drone just pitched up. Drone s pitching over. Drone is uh, crashed and destructed, at uh, the end of the runway. UnidenHfied pilot of a chase plane that was following a QF- 4E target drone before it crashed at Tyndall Air Force Base in Florida on July 17, We re in the soup here.... Dude, uh, we re not sure what the aircrae is doing.... Yeah, we crashed. UnidenHfied pilot of an Air Force Reaper as it crashed in Douglas County, Nev., on Dec. 5, Whoa.... I don t know what the hell just happened. Where the hell is where is the runway? It s all the way over here. I overshot. Oh, shit. I think we lost the engine. Oh, shit, oh damn, oh my God, what is that?... What was all that stuff I just hit? Air Force Capt. Mabhew Scardaci as his Predator crashed into a row of empty shipping containers at Kandahar Air Base on May 5, I couldn t tell which way it was turning, or if it was straight, if it was upside down, or if it was right- side up.... I couldn t grasp what was happening with the aircrae. And he said he thought it was upside down. UnidenHfied Predator pilot to inveshgators trying to determine how and why she flew the drone upside down before it crashed near Kandahar Air Base on Jan. 15, Um, I guess I ll just be blunt and say not well. The Predator pilot who flew upside down, when asked by inveshgators how well her training had prepared her for such an incident. Whitlock (2014) Washington Post. 9

10 A VERY ParHal List of Issues Pilot selechon/ cerhficahon/ training GCS database compahbility Lack of GCS Standards Pre- flight planning Lack of sensory cues GCS Human Factors Best PracHces Clumsy automahon Detect and Avoid Well Clear Collision Avoidance Lost Link Visual clearances Surface operahons 10

11 How can the industry reduce human performance errors? Introduce Human Factors early on in a human- centered design process Design to let people perform the tasks where they are superior Novel condihons Pabern recognihon Decision making Let Computers do what they are good at Number crunching Vigilance IntegraHng diverse sources and large amounts of informahon Don t automate with le6over principle Design robust, flexible automahon that is mission/scenario driven 11
