F-35C being test aboard aircraft carrier USS Abraham Lincoln

[mor10]

Can it measure the vertical acceleration? I'm not sure why it is needed though if the problem is solved according to users.

Yes, I agree, but as you mentioned comparing to other aircraft and loads etc. This would be a cheap way of removing all other very expensive factors from the equation.

It sure can. One needs to take into account the precision of those devices though - and the calibration. Unsure how good the measurement would be.

How accurate would it need to be? Human perception, or discomfort, which is what we are dealing with, is not an easy thing to clasify either.

On the other hand, if they somehow log the movement of the "smart" helmet, they already have the data available.

Perhaps humans are the best sensors here

Certain injury will not immediately pop up with human use. RSI for example will usually not show its ugly head within a few months.

So together with proudness and peer pressure I doubt humans are a good sensor for cases like this.

We also do not need super accuracy (like down to 0.01 G). Having used a smartphone to sense g-forces on a track-day I remember it got pretty near the pro rally g-sensors results when we compared.

The only thing I am not sure about is the peak G a smartphone can sense and if that would be accurate enough for measuring the forces of a deck launch.

This 'sensor' thingy has become a storm in a teacup. The 'hard bobble' was only experienced during lightweight catapults when (at moment) new F-35C pilots carrier qualify. Pilots so far have reported that the fix means there is not a problem.

The Air Force’s 33rd Maintenance Squadron provided training and support to F-35C Lightning II operations aboard the USS Abraham Lincoln (CVN 72) from Aug. 30 to Sept. 7, 2017.

Two Airmen and two Sailors from the aerospace ground equipment flight and the wheel and tire shop qualified Abraham Lincoln Sailors to operate F-35 support equipment, bringing the U.S. Navy one step closer to initial operations capability.

"We are the most qualified unit to (train these Sailors)," said Staff Sgt. Mark Gower, 33rd MXS wheel and tire technician. "We have been working with this jet the longest because the 33rd Fighter Wing was the first unit to receive the F-35 from the test community."

Air Force supplements F-35 at sea
13 Sep 2017 Story by Staff Sgt. Peter Thompson 33rd Fighter Wing/Public Affairs

"The Air Force’s 33rd Maintenance Squadron provided training and support to F-35C Lightning II operations aboard the USS Abraham Lincoln (CVN 72) from Aug. 30 to Sept. 7, 2017.

Two Airmen and two Sailors from the aerospace ground equipment flight and the wheel and tire shop qualified Abraham Lincoln Sailors to operate F-35 support equipment, bringing the U.S. Navy one step closer to initial operations capability....

...The Airmen and Sailor’s role extended beyond training for this embark, they were also directly supporting carrier qualification for F-35C pilots.

Strike Fighter Squadron (VFA) 101 and VFA-125 flew six aircraft aboard the Abraham Lincoln to execute initial carrier qualification for 13 pilots, training that cannot be replicated on-shore. This qualification requires pilots to take off and land the jet during day and night operations.

"We do this to learn the capabilities of the aircraft and hone our abilities in a carrier environment," said U.S. Navy Lt. Cmdr. Matthew Coulter, VFA-101 instructor pilot. "The training we put in now will allow us to focus on implementing the aircraft as intended in the future."

This is the second time both fighter squadrons have deployed from an aircraft carrier at sea to gain experience using the arresting gears and working with the full complement of flight deck personnel on the ship.

"Every time the F-35 embarks on an aircraft carrier there are many lessons learned," Coulter said. "While we are at sea we are able to accomplish flight deck familiarization for pilots and maintainers alike, while attaining the carrier qualifications we need as pilots and landing signal officers."

The Navy currently has plans for several more underways with the F-35C, where the 33rd MXS will continue to train and qualify Abraham Lincoln maintainers on these systems.

"That’s the whole point of this aircraft being a joint program," Coulter said. "The 33rd MXS is a part of future integration of the F-35C and all of the U.S. Navy carriers. It comes down to being prepared at all times for whatever we are tasked with. Once the F-35C reaches Initial Operational Capability, it will be a tool at the Navy's disposal. We will be ready to sustain this aircraft's operations so we can carry out the mission sets we are directed to.""

Does anyone know the BuNos of the aircraft that were on board, especially the two VFA-125 aircraft?

VFA-101
169305 NJ-101
169161 NJ-122
169163 NJ-124
169304 NJ-127

VFA-125
NJ-406
NJ-411

(underlined BuNos are from http://forum.scramble.nl/viewtopic.php?p=878553, second post.)

[spazsinbad]

I'm searching DVIDS and boy do they have a lot of misinformed comments for their photos. Anyhoo here is a zoom of NJ 411 but cannot read BuNo. https://www.dvidshub.net/image/3744287/ ... oln-cvn-72

[spazsinbad]

Here is BuNo for NJ 412 is 169303 - so probably BuNo for NJ 411 is one less number 169302?

Thanks spazsinbad, I was thinking the same, also because 169302 was previously NJ-125, but I haven't seen pictures of it since December 2016. It quite possible it is indeed NJ-411 now. A candidate for NJ-406 could be 169160. 169160 was flying as NJ-121, but I haven't seen it since August 2016.

USS Abraham Lincoln (CVN 72) Completes First F-35C Carrier Qualification


The Nimitz-class aircraft carrier USS Abraham Lincoln (CVN 72) successfully completed Fleet Replacement Squadron (FRS) Carrier Qualifications for the F-35C Lightning II program, carrier qualifying the first nine fleet aviators in the new aircraft, while underway Dec. 7-11.

Along with Abraham Lincoln, the "Rough Raiders" of Strike Fighter Squadron (VFA) 125, the "Grim Reapers" of VFA-101, and VX-9 accomplished many first steps including first-time use of Autonomic Logistic Information System (ALIS) aboard a carrier, and use of the Joint Precision Approach and Landing System (JPALS) in an operational setting.

"Thanks to the tireless work from the VFA-125, VFA-101, VX-9, CVN72, and the Lockheed Team this detachment was able to successfully complete numerous milestones that will set the foundation for the future 5th generation employment of the F-35C into the Carrier Air Wing," said Cmdr. Scott Hulett, VFA-125 executive officer.

One of those milestones achieved was with ALIS, an information infrastructure that allows operators to plan, maintain, and sustain systems over the F-35Cs. The system provides a secure way to transmit up-to-date operations, maintenance, prognostic, support, training and technical data to users and technicians worldwide. According to Lockheed Martin, the developer of the F-35C, ALIS is considered the IT backbone of current and future aircraft throughout the Department of Defense.

Abraham Lincoln operated in inclement weather during portion of the qualification process, which gave the squadrons varying condition to test the new landing system, JPALS. The all-weather system works with the ship's navigation system to provide accurate and reliable guidance for the aircraft. Prior to this underway, F-35Cs only used JPALS for developmental testing.

While the pilots put new systems to the test in the air, Abraham Lincoln Sailors, both on and below deck achieved important milestones. The aircraft intermediate maintenance department performed their first unassisted F-35C tire change. This accomplishment provided proven capabilities that will help ensure full and successful integration of the air wing with Abraham Lincoln.

"We could not have achieved our lofty goals without the dedication and expertise from everyone involved. We look forward to working with the CVN72 team throughout 2018 as we continue to ensure 5th generation power projection from the sea," said Hulett.

By 2025, the Navy's aircraft carrier air wings are forecasted to consist of F-35C, F/A-18E/F Super Hornets, EA-18G Growlers electronic attach aircraft, E-2D Hawkeye battle management and control aircraft, MH-60R/S helicopters and Carrier Onboard Delivery logistics aircraft.

F-35C Aviators Carrier Qualify Aboard USS Abraham Lincoln
18 Dec 2017 Ben Werner

"...while Abraham Lincoln was underway, nine F-35C aviators with the “Rough Raiders” of Strike Fighter Squadron (VFA) 125, the “Grim Reapers” of VFA-101, and VX-9 carrier qualified in the Navy’s first stealth fighter. In October, F-35C aviators qualified aboard USS Carl Vinson (CVN-70), according to a Navy spokesperson....

...Below deck on Abraham Lincoln, the aircraft intermediate maintenance department performed their first unassisted F-35C tire change, according to a statement released by the Navy. The tire change is considered significant, the Navy statement explained, because the accomplishment suggests the airwing will successfully integrate with Abraham Lincoln."
