Stevie Stevie Stevie.... This thread has all the info PLUS there is a specific SRVL thread but it only documents the SRVL and sometimes the associated gear such as the BEDFORD ARRAY. Test Pilots including the great WHIZZER WILSON HISSELF have stated a few times that SRVL will be tested during this QE two part test period and it will be WITHOUT the BEDFORD ARRAY installed aboard QE. The array will be installed PoW and later QE. My speculation has bin 'how QE SRVL without'?

Yes SPAZ does go on and on and on about the BEDFORD ARRAY. But WHY? Probably because it is essential to the SRVL approach BUT APPARENTLY NOT for test pilots. One of them has stated in this thread that using the ARRAY and the SRVV Ship Relative Velocity Vector for the SRVL approach is not easy (I guess requiring practice) which at moment is only in SIM.

The FIRST TEST PERIOD is in two parts (with some time alongside in USofA inbetween). Then in 2019 is 2nd TEST PERIOD.

Secondary thread: F-35 the QE and SRVL BOLTERS
viewtopic.php?f=22&t=29798&p=320457&hilit=SRVL#p320457

Searching F-35 sub (not submarine) forum(s) using SRVL will probably find a bunch o'stuff which I have not done today.

U.S. Marine Pilot Becomes A Part Of Aviation History
09 Oct 2018 JPO PR

"...For 11 weeks, Marine Corps Maj. Michael Lippert, an F-35B test pilot, and three British pilots will test the performance of the F-35B Lightning II on the deck of the HMS Queen Elizabeth, the United Kingdom’s newest and largest aircraft carrier. Lippert was selected to be a part of this mission based off his position as the Marine Corps’ F-35B ship suitability project officer and his previous shipboard operational experience as a Harrier pilot.

Collectively, the pilots are expected to conduct 500 takeoffs and landings onto the ship’s 280-meter deck.... [not sure if this meme is correct - it may mean 500 test points but that is only my guess - we'll find out soon enough]

...The trials will also evaluate jet performance on more than 200 test points during various weather and sea conditions...." [this could indicate that my guess is wrong but it could just refer to 200 of the 500 test points (my guess)]

"History" eh?

Ten years from now very few will remember and fewer yet will care about this 'first'. Meanwhile, there are forces that remain in harms way on distant parts of the planet.

More interesting than Osprey is this Twitter tidbit garnered from earlier USMC F-35B crash report fallout by 'hyltheday':
viewtopic.php?f=22&t=54487&p=403552&hilit=Brits#p403552
11 Oct 2018 "...Contrary to reports, all F-35 jets have not been grounded. We have paused some F-35 flying as a precautionary measure while we consider the findings of an ongoing enquiry.

F-35 Flights Suspended While F135 Fuel Tubes Checked; UK F-35Bs Keep Flying on HMS QE
11 Oct 2018 Colin Clark and Paul McLeary

"WASHINGTON: It may not last long, but the entire F-35 fleet — all versions from all countries — was just grounded “while the enterprise conducts a fleet-wide inspection of a fuel tube within the engine on all F-35 aircraft.” The British — clearly hungry to keep their two F-35Bs flying as they press ahead with testing aboard the HMS Queen Elizabeth — have checked their planes already.

A British defense official who spoke on the condition of anonymity told us the crew of the Queen Elizabeth “has checked her embarked jets and flight trials are continuing… they are flying today.”

We just got this official statement from the British MoD, clarifying how they are handling this across their F-35B fleet: “Safety is our paramount concern, therefore the UK has decided to pause some F-35 flying as a precautionary measure while we consider the findings of an ongoing enquiry...."

F-35 flight trials from the aircraft carrier, HMS Queen Elizabeth, are continuing and the programme remains on schedule to provide our Armed Forces with a game-changing capability. We will continue to review the situation as further information becomes available.”..."

UK MoD PR is run by kindies for sure - however I will concede perhaps there is some wordplay involved but I apologise not.

Carrier deck launching of adapted land-based airplanes
23 Jul 2017 HERNANDO, José-Luis and MARTINEZ-VAL, Rodrigo - Department of Aircraft and Spacecraft
School of Aerospace Engineering; Universidad Politécnica de Madrid; 28040 Madrid, Spain


"Abstract
Harrier VTOL is the basic combat airplane for many Navies, but it will soon be retired from service. Three main alternatives appear: to incorporate another, already existing or under development airplane; to design a completely new aircraft; or to modify an existing land-based airplane for carrier suitability. The present paper is part of a study to assess the feasibility of the third option. In former papers the authors have addressed the compatibility of land-based airplanes with aircraft carriers and the details of the carrier approach guidance and recovery; and showed some major modifications required in wing structure and landing gear. The research proposed here studies the airplane performance during the launching manoeuvre, formed by a take-off run on the flat deck followed by a ski-jump....

5. Conclusions
The present paper has been devoted to assess the feasibility of launching an advanced combat airplane from a midsize carrier, without entering into the complex analysis of how such aircraft would board the vessel, topic that would deserve a specific study. As an example of critical aircraft/vessel combination Eurofighter Typhoon (EFA) and Juan Carlos I have been used. Needless-to-say, any analysis on the aircraft/vessel compatibility topic is highly specific and cannot be extrapolated to another combination.

In this research a number of aerodynamic features of the aircraft have been estimated, with methods proper of preliminary design and, therefore, the findings presented here have such depth level. The key finding is that EFA is capable of safely operate from a mid-size carrier without catapult, and the only help of a ski-jump on the ship’s bow. The fly-away from the end of the curved deck follows a trajectory compatible with common piloting practice.

Interestingly, the aircraft requires no major modifications for the launching manoeuvre, as opposed to what can be expected from the recovery, this last due to the much higher than normal vertical speed at touchdown in sea approaches. This preliminary study has been carried out with the original all up weight. This means that the land-based airplane could perform the manoeuvre without being penalized for the requirement of taking-off from a carrier, and would keep all its combat capability.

Additional research is necessary to confirm the preliminary results, to assess the effectiveness of thrust vectoring control, and to optimize piloting control laws and airplane attitude during the initial fly-away phase."
