Oriana Pawlyk, Military.com When Air Force Secretary Heather Wilson visited AFWERX's Pilot Training Next program in Austin, Texas, last year, she watched as trainees took flight from the seats in front of her — through the use of virtual reality. It piqued her interest enough to ask service officials to explore waysthat similar flight simulator programs could be introduced to high schools to get young students involved in the nation's endeavors to create more pilots. Officials with Air Education and Training Command (AETC) are now gearing up to present Wilson's successor with a business case for more widespread use of the system, within the force. The move provides a glimpse into Air Force leaders' thinking as they overhaul the pilot training curriculum, introducing one that augments time airborne in the cockpit with simulators and technology on the ground. It comes as the Air Force readies itself for the possibility of complex conflict with a peer-level adversary equipped with long-range missiles and advanced combat aircraft. It's a future that may represent a strong contrast to recent decades, in which the Air Force has flown in largely uncontested airspace supporting ground troops. The service is attempting to boost its pilot ranks amid a longterm pilot shortage, even as its trainer fleet ages. Air Force officials say they want to move away from the service's old-fashioned, "industrial" approach to training — having pilots sit in classrooms for weeks then moving on to a trainer. This means using virtual reality earlier and more frequently in the training pipeline. As the service prepares to bring its latest trainer, known as the T-X, into the fold, it is proposing a more "concentrated dose" of training to seamlessly transition from virtual reality to the trainer and, finally, to the Formal Training Unit, or FTU. The system is well poised to reform in a few ways, said Gen. Mike Holmes, commander of Air Combat Command (ACC). Using the low-cost immersive environment of virtual reality, together with "competency-based learning," and moving skillset testing at the graduate level to an earlier place in the model, "would experience our pilots much faster," he said. "Those are two things that are poised to make a revolutionary changein how well we train pilots and in how long it takes us to train pilots," Holmes said Tuesday in an interview with Military.com. "I want to see how fast and well I can produce experienced pilots." Pilots end up leaving the service if they feel dissatisfied and lack a sense of purpose, added Lt. Gen. Steven Kwast, AETC commander. "You have to fly a lot to be good at what you do, and we don't have the money, and we don't have the weather, and we don't have the range space ... [because of] sequestration. And all these things that are politically driven oftentimes are frustrating the force," Kwast said in a separate interview. Airline hiring efforts are the biggest factor that drives pilot retention and production problem in the services, officials have said. Old learning mechanisms also bog down the system, often adding to pilots' frustration, Kwast said. "We would [add] layers of things over time" through the course of a pilot's service, "basically assuming, 'You can't handle the truth!' or 'You're not smart enough to be able to learn this holistically, we have to give it to you piecemeal and then you'd put it together in your brain over time.' That's why it would take seven years to make a great mission commander pilot." But now, he said "We're breaking that paradigm." Trainer fleet in trouble? The service still relies heavily on its trainer fleet for training, even though virtual reality is the new frontier, Holmes said. "There's still no substitute for being in a real airplane," he said. "I think we'll always want a mix of learning our skills cheaply, but also build on decision-making in a real airplane." The T-38 Talon has been the backbone of the Air Force's undergraduate pilot training, or UPT, program for decades. But last year, the trainer fleet was plagued with a series of crashes, two of which were fatal. Those selected to fly bombers and fighters typically receive their advanced pilot training in the T-38. The T-1A Jayhawk, meanwhile, is used in advanced training for students who are slated to go into cargo or tanker aircraft. The T-6 Texan II, used for instrument familiarization and low-level and formation flying, also has had its share of problems. Last year, the Air Force ordered an operational pause for the T-6 fleet after pilots suffered a series of unexplained physiological episodes, or UPEs. As a result, AETC on Feb. 1 ordered an indefinite operational pause for all T-6 aircraft at Columbus Air Force Base, Mississippi; Vance Air Force Base, Oklahoma; and Sheppard Air Force Base, Texas. That pause was lifted Feb. 28. A team of experts determined that the T-6's On-Board Oxygen Generating System (OBOGS) filter and drain valvesfailed at higher rates than expected. The discovery led to repairs and increased inspections, but pilotscontinued to suffer from UPEs. A T-6 trainer from Sheppard Air Force Base, Texas, crashed just last week. The Air Force is preparing to receive new trainer jets to replace its current Northrop Grumman-made T-38s, some of which date to the mid-1960s. In September, the service awarded Boeing Co. a $9.2 billion contract to build its next aircraft for training pilots, known as the T-X program. The first T-X aircraft and simulators are scheduled to arrive at Joint Base San Antonio-Randolph, Texas, in 2023. The service has committed to buying 351 T-X jets, 46 simulators and associated ground equipment. The pay ment structure, officials have said, also allows for an indefinite-delivery, indefinite-quantity option to give the Air Force the opportunity to purchase up to 475 aircraft and 120 simulators. Delays to this program or other unforeseen challenges could have catastrophic consequences, said retired Gen. T. Michael "Buzz" Moseley, former Air Force chief of staff. "My anxiety over this when I was the chief [is that] we are one sortie away from this older inventory having a problem," Moseley, an F-15 Eagle pilot, said in a recent interview with Military.com. "Here we are in 2019, and we're going to fly these airplanes until 2024 before T-X starts coming in." Kwast and Holmes agreed that the T-38 fleet will continue to undergo any upgrades necessary to keep them flying as long as it makes sense. "You can make anything last longer; it just takes more money to sustain," Kwast said. "I guarantee that the T-1, the T-38 and the T-6 all can last as long as we need them to last, depending on the business case and the amount of money you want to spend. But will the T-38 or the T-1 become too expensive, and [therefore], we have to jump to a different technology? Then we would look at other options." Boeing said it stands ready to produce the T-X. "Our T-X program, including engineering, manufacturing and test, is located in long-established Boeing St. Louis facilities," wrote Rachelle Lockhart, spokeswoman for the company's T-X program, in an email. "In fact, we built and assembled our first two T-X aircraft in St. Louis prior to contract award to prove the maturity of our design, repeatability in manufacturing and performance. We're now on contract, executing on schedule as planned, as are our suppliers." She added the trainer's production schedule could be advanced at the Air Force's request. "The US Air Force plan calls for a full production rate of 48 jets a year, and we will meet the customer need," Lockhart said. "Should the Air Force request a higher rate of production, we are well positioned to accommodate it."

By: Stephen Losey New designs will be required to fix some of the issues with the refueling boom and the remote vision system on the Air Force's new KC-46 Pegasus tanker, and that could take years to fix, the Government Accountability Office said in a report released Wednesday. The refueling boom on the Pegasus could inadvertently scratch fighter jets' stealth coatings, or otherwise damage aircraft, according to the GAO. The good news is that the cost of delivering all 179 KC-46 tankers is now expected to come in at $43 billion, or nearly $9 billion cheaper than originally estimated in 2011, GAO said in the report. More, the KC-46 is ultimately expected to meet all 21 of its performance goals. But delays in the program mean that Boeing will not be able to make good on its most significant delivery requirement — delivering nine sets of wing aerial refueling pods — until mid-2020, or nearly three years later than originally expected. In addition to previously reported foreign object debris problems, the GAO report details deficiencies with the tanker's remote vision system and refueling boom — which could damage aircraft, especially stealth coatings. As has been previously reported, the remote vision system's cameras sometimes had problems with glare when the sun shone at certain angles, GAO said. This caused the display screens to be washed out or blacked out during some test flights, and the aerial refueling operators had a hard time seeing the receiving aircraft's receptacles to guide in the boom. The system also doesn't provide enough depth perception in some lighting conditions, GAO said. Boeing said it has already made changes, such as adjusting the contrast on the display screen and allowing operators to more quickly switch between different viewing options. However, GAO responded that those changes didn't fix the underlying problem: KC-46 operators need to be able to refuel aircraft in all conditions, with sufficient visual clarity in all lighting conditions. Boeing has agreed to redesign the vision system to do so, but the redesign could take three or four years, plus several more years to install it in the planes. That vision problem also caused the boom nozzle to bump into the receiving aircraft, without the knowledge of the refueling operators. This could damage the antenna or other structures near the refueling receptacle, GAO said. This especially presents a problem for low-observable planes such as the F-22 fighter, because inadvertent boom nozzle contact could scratch or damage special stealth coatings, and make them visible to radar. GAO also said the Pegasus' telescoping boom is stiffer than expected, which means lighter aircraft — such as the A-10 and F-16 — must use more power to move the boom forward while in contact to compress it and stay in refueling position. The need for additional force can create a problem when the receiving planes disconnect from the boom. When they disconnect, their additional power can cause them to lunge forward back into the boom, which could damage the plane and the boom itself. For the A-10, because the receptacle is located on its nose, a collision with the boom could damage the windshield and put the pilot at a greater risk. Boeing said that fixing that problem will require a hardware change, which could take three or four years to be designed and certified by the Federal Aviation Administration. But because the contract didn't specify how much force should be needed to compress the boom, and because the Air Force signed off on Boeing's original proposed specifications, program officials said the Air Force will have to foot the bill. The total cost for designing and retrofitting roughly 106 KC-46s? More than $300 million, GAO said. https://www.airforcetimes.com/news/your-air-force/2019/06/13/kc-46-refueling-system-flaws-will-take-years-to-fix-and-cost-hundreds-of-millions-of-dollars-gao-says/
