The deck of the new Queen Elizabeth Class aircraft carriers may be the size of four football pitches and supported by the best part of 65,000 tonnes of steel but, from three miles (5km) out, when viewed through the BAE Systems simulator at Warton, it’s tiny and the target area for landing looks even smaller.

Add in your 150-knot (278km/h) speed, a keen wind, a rolling sea state, a touch of mist, a black night, and you can see why landing an aircraft on a ship is probably the most difficult task most pilots will ever face.
Welcome to the deck of one of the Queen Elizabeth Class aircraft carriers, due in service by the end of the decade. Well, not quite the real carrier, which is under construction at Rosyth. This is BAE Systems‘ simulator at Warton, the only one in the world where the F-35 aircraft meets the future pride of the 2020 Royal Navy.
But this is not about training pilots, nor honing the skills of the personnel whose deck-based task is to guide the aircraft in safely.
This is about designing the flight deck, making sure its massive array of coloured lights and lenses, deck markings and arrestor gear make for the safest environment for recovering the aircraft.
Tests are at an advanced stage using US Navy F-18 pilots, hugely experienced in taking off from and landing on carriers.
This is something new for the UK. Our carriers, remember, have operated the short take off and vertical landing (STOVL) Harriers for more than a generation. Skills in landings are, shall we say, a little rusty.
Tests will inform the Aircraft Carrier Alliance on design of the deck. With every simulated landing, Defence Equipment and Support’s Joint Combat Aircraft Team learns more about the behaviour of the F-35’s Carrier Variant (CV), the F-35C, which the UK will be operating – a decision firmed up by the Strategic Defence and Security Review.
The simulator at BAE Systems in Warton is hosting tests to design the deck of the Queen Elizabeth Class carriers:
„Basically we are dealing with a completely different method of landing,“ said Pete Symonds of the Aircraft Carrier Alliance.
„With STOVL landing you stop and land; CV landing is land and stop. So it’s a completely different set of lights in completely different positions. Then the aircraft is different. We’ve built a new model into the system as clearly the control laws are different with many different characteristics including an arrestor hook.“
The team has adapted well to the changes though:
„From the ship point of view it has been an easier task to organise the lighting system as we are now following how the Americans do it. The American layouts have been our starting point and we’re trying to improve on them,“ said Mr Symonds.
„And we’re helped by the fact that the actual size of the carrier flight deck was driven by the requirement to be adaptable. The STOVL ship could have been smaller but the adaptable design was driven by the size of the runway, which was needed to recover the aircraft.
„We’ve taken the flight deck, and started again. After the decision was made to move to the Carrier Variant we had a period of looking at variable equipment selection before we started the work.
„We now have the flight deck at what we call level two maturity, so effectively the big bits are already fixed. The design of the flight deck is pretty well sorted.“
Testing will soon move to other simulators to test recovery of helicopters to the carriers.
From the Joint Combat Aircraft (JCA) Team’s point of view the F-35C will be equally capable from sea or land:
„The current focus for the JCA Team is ensuring the aircraft is integrated onto the carrier in the most optimal way,“ said Wing Commander Willy Hackett, the team’s UK Requirements Manager.
„This aircraft will be the first stealth platform to operate from an aircraft carrier, which will bring new challenges. Recovering an aircraft to a small moving airfield, especially at night or in poor weather, has always focused the mind of any pilot who has flown at sea.
„The F-35 will bring new technology which in time will make landing on an aircraft carrier just another routine part of the mission. On entry into service the aircraft will be equipped with the Joint Precision Approach and Landing System [JPALS] which will guide the aircraft down to a point where the pilot can take over and land the aircraft manually.
„Future upgrades intend to allow JPALS to actually land the aircraft without pilot input in very poor weather.“
„A new flight control system, combined with new symbology in the helmet-mounted display, looks to drastically reduce pilot workload on a manually flown approach.
„This technology is being investigated by the US and UK, and if successful will see a major reduction in the training required to keep pilots competent at landing on aircraft carriers from the middle of the next decade.
„Once this new technology is invested in the F-35C the pilot will be able to focus on the mission to an even greater extent than is possible now in the current generation of carrier variant aircraft.
„UK JCA squadrons will therefore be more operationally focused than current generation sea-based aircraft and will keep UK air power at the front rank of military powers.“
