LONDON — Rotary pilot and rear crew training capabilities for the British military have been given a lift with an order for additional Airbus helicopters in part of a wider boost to a package of improvements announced Jan. 21 by the Ministry of Defence.
The £183 million (U.S. $238 million) deal will see Airbus supply four of its H145 helicopters to the rotary wing element of the U.K. Military Flying Training System program. UKMFTS is run by the Babcock-Lockheed Martin joint venture Ascent Flight Training Management in partnership with the MoD.
Aside from the H145 helos, known in Britain as Jupiters, the MoD has funded the acquisition of another simulator, made by Canadian vendor CAE, and infrastructure improvements at Royal Air Force Shawbury, the headquarters of Britain's tri-service helicopter training effort.
“The new H145 helicopters and simulator will enable students to learn how to fly a range of missions, covering expected scenarios on operational deployment. In addition, the H145s enable students to practice winching tasks and rear crew activities,” the MoD said in a statement announcing the deal.
“It is part of a wider program to increase training capacity for UK military pilots overall, as part of the £3.2 billion UKMFTS program and helps address the increased demand for pilot training identified in the 2015 Strategic Defence and Security Review,” the statement added.
The helicopter element of MFTS currently operates 29 Airbus H135s for basic training, and three H145s for more advanced pilot training and particularly for rear crew work like winching. The H135 is known in Britain as the Juno.
All four aircraft are expected to be delivered to the MFTS program by the end of this year.
The more than doubling of the H145 fleet reflects the increasing number of rotary rear crew and pilots required by the British military. Crew shortages in fixed- and rotary-wing sectors have caused concern at the MoD, with Defence Secretary Ben Wallace saying late last year that fixing the problem is a top priority.
To help meet demand, additional fixed-wing aircraft may also be added to a fleet that already includes T-6 Texans, Phenon multi-engine trainers and King Air rear crew trainers.

By Steve Trimble The U.S. Air Force has selected the Northrop Grumman B-21 to demonstrate a potentially revolutionary approach to flightworthy software. The future stealth bomber will demonstrate a software architecture running the operational flight program (OFP) that learns and adapts as it flies a mission, says Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics. Such an approach potentially “allows them to land with better code than they took off with,” Roper tells Aerospace DAILY. The architecture enables the code to update itself during a mission. Asked if the demonstration involves software code in the OFP, the operating system of a military aircraft, Roper replied affirmatively: “Within the OFP. That kind of adaptability is what we want to aspire to.” As a special access program, details of the B-21's schedule, capabilities and even cost are kept secret. But Roper says he is able to discuss what he calls the “digital bullet challenge,” albeit within strict limits. Asked if the B-21 software demonstrations imply the insertion of a deep learning technique known as a neural network, Roper declined to answer. “Details of how I won't go into,” Roper says. “But B-21 is trying to not just do agile software. They want to blaze new territory, a new trail for the Air Force. The idea that one of our most complicated airplanes with one of the most challenging missions is also taking on one of the most challenging software approaches to make their software living [and] breathing on the plane itself is inspiring. “They're going to be pushing the boundaries of how aircraft software should work in this century, and increasingly the software is where the cutting edge—the winning edge—is going to come from,” he explained. Roper's description appears to push the boundaries of software used in the flight computers of a commercial or military aircraft. Aircraft certification standards demand a highly rigid approach to software architecture, with the function of each line of code validated and verified on the ground before it is allowed to be used in flight. The challenge set for the B-21 could lead to altering or even adding software lines of code in the OFP during a flight. The Air Force launched the B-21 program in 2015 by awarding a $21.4 billion contract to Northrop. Air Force officials have previously announced that first flight is scheduled around December 2021. The aircraft will take off from Northrop's final assembly center in Palmdale, California, and fly to the flight test center on the adjoining Edwards Air Force Base. https://aviationweek.com/defense/usaf-picks-b-21-software-learning-demo-challenge
