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.

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 :D

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."

'popcorn' highlighted this article above however my replication of same article is to highlight the details bolded below.
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.)

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

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.
