F-35 Cancelled, then what ?
How do all the automatics cope with a ski jump?
I suppose you could worry about steering, which old-school catapulted jets have done for them, but even that's easier on a ski-jump than flat deck because the visual cues are so much better and there's no need to raise the nose during the T/O roll.
So I imagine it will do it very nicely.
*But they must be, rightly in my opinion, pretty confident.
**noting of course that, in the words of the guidance notes for a once-popular DStan: "nothing is safe".

Courtney,
I think I've posted several times that the F-35B has a hard requirement (a KPP, even) to be able to carry out a ski jump.
So, the automatics will cope very well with a ski jump because they have been designed to do so. The aircraft won't be accepted unless it does. It just has to. I don't think I can be any clearer.
Initial design work started some years back, and even then it was clear that, as for the Harrier, a ski jump launch would be the lowest workload way to get into the air, with significant safety benefits and substantial improvements in payload. NoHoverstop's excellent answer provides great detail.
Hope this helps
Best Regards as ever

Flight Restrictions Kept In Place For F-35 Operational Aircraft 31 Jul 2014
"Flight restrictions remain for Joint Strike Fighter operational aircraft until an engine investigation wraps up, but limits have been removed for test aircraft, according to the F-35 joint program office...."
Thanks Spaz, for that as I could not remember which one of the carriers was left at the bitter end. IIRC, Sydney was used as the 'Vung Tau Ferry' for transporting troops and vehicles probably the RAAF and 191 Flt Hueys and Sioux and Turbo Porter
Then again didn't our remaining TDCs sorry carriers still had ski jump post getting rid of JFH, so how can said ski jump impair rotary wing ops as some1s stated about the Canberra's design.
Though apart from the Italian Guiseppe Grimaldi and Spanish Principe de Astrias - the USN/USMC did not have ski jumps because the old Iwo Jima LHA were helicopter carriers and built in post WW2 period then the Tarawa class did not have ski jumps and they were built 70s/80s? The WASP class does not have them - magic question how did the Flying Leathernecks cope in the last 4 decades with Harrier launches?
Cheers

'chopper2004' I guess skyramps are in the eye of the beholder. Some beholden more than others beford. But whatever.... Back in the dreamtime a USMC study concluded that a ski jump on the LHAs of that era would not take away a helo spot even if on a slight incline because when well deck flooded helo ops continued on the inclined deck. It seems the USN/USMC did not want ski jumps so that was that. USMC Harrier pilots have usually been enthusiastic about ski jumps but that did not carry weight.

"...Not your father's ski-jump
The QE-class's ski-jump, too, has been carefully designed and engineered from the beginning... The QEC's ski-jump is longer (200ft) than the Invincible-class (150ft) and designed so that the aircraft has all three (including the nose) wheels in contact right up until the point where the aircraft leaves the deck — giving positive nosewheel authority throughout. Additionally, the F-35Bs smart flight control system ‘knows’ when it is going up a ramp and will pre-position the control surfaces and effectors to launch at the optimum angle to avoid pitch-up or down...."

"...Just thinking that a flight from Edwards to Pax may be outside the allowed envelope and how are the Marine F35s that had been planned to "display" at RIAT etc going to get back to the West Coast, a number of little hops skips and jumps across the continent? Interesting logistical support exercise."

Spaz, thank you for your response to my post. Are you sure about your answer? You quote an article of 16th July, before as I recall the decision not to go to RIAT, 17-19 or Farnborough 19-20. You seem to be stating that the Marines flew the planes back west before the decision no to fly trans Atlantic, could you confirm what you stated was strangely correct?
