Yes Tomo I believe it is totally hrs related. Having said that each person is different and would require a different amount of retraining.
I am not an instructor nor a 3 axis pilot, so I don't know the full solution to the problem.
The hrs required may also depend on the conditions the training has been conducted in as well, but I really am not sure?
Once a parallel primary response has been learned then flying both forms is not an issue, and certainly there are many ( including high hr professional pilots ) that also fly trike regularly.
Hit by a gust, thermal, or just plain beginner flying may require an immediate response to correct the situation. Respond the wrong way and you have the potential to make matters much, much worse very quickly, perhaps even unrecoverable especially if involved in takeoff or landing where height is not available.
John, normally I value your opinion and bow to your far greater experience, but on this I very much disagree. Yes the official findings from accidents do not highlight this as a problem.
Never the less the facts are there if you care to look for them.
I indicated earlier this is one of my pet subjects.
Last year I was training at the same time, same place as the pilot the 3 axis pilot that came to grief.
I was new at this game so did a lot of research, sole searching and talking to other pilots, including high hour commercial pilots, GA instructors and trike pilots and instructors.
My issue and motivation was - was my new chosen hobby and the decision to spend $65k+ and a heap of time and $ training greatly flawed and unsafe to the extreme.
Should I seriously reconsider my options.
If someone with so much experience, was who was very safety conscious could come to grief so easily, what had I let myself in for.
This research lead me to believe ( correctly I hope) that there is a real issue with 3 axis conversion training.
Interestingly the 3 axis instructors I discussed it with believed to go trike to 3 axis was not really an issue.
Before my flying time ( about 5 years ago), another trike pilot also came to grief in my area. Different instructor / training etc.
SAME issue - hi 3 axis low trike. Both pilot were highly respected flyers within the flying community.
I think there may also have been another one as well about the 6 year ago mark with similar flying history.
Research of trike accidents around the world often had the same facts stated in the limited information available - " hi 3 axis low trike hrs.
From where I stand - common and likely. ie All recent trike fatalities in my area have this as a common factor and it appears to be common enough around the globe. ( enough to be greatly concerned and needing addressing)
I AGAIN SAY I AM NOT SAYING THAT THIS WAS THE CAUSE OF THESE FATALITIES. IT IS NOT MY PLACE TO MAKE THAT DECISION NOR WAS IT THE OUTCOME OF THE INVESTIGATION. However the facts are still there and the issue is known and accepted as a problem.
Andy, as I read it, you may not have had any issues as your 3 axis may not have had a lot of currency with it, and maybe the hrs were low?
My guess is the higher the 3 axis hrs the more established the 3 axis primal response is , so the longer it will take to build a new one.
I will go out on a limb here and suggest that ( from my perception / experience) trike flying is very much seat of the pants flying. Very much a touchy feely thing in a responsive machine that needs to be kept within its designed flight envelope. You don't so much look and control, more an unconscious feel and respond as one with the trike. In the early part of training / conversion if the respond is the wrong way things go pear shaped very quickly.
( maybe) The non 3 axis trained pilot has many other factors to slow their training down to a pace that allows development of their trike primal response. The 3 axis pilot short cuts this with his prior training ( ground coming up quickly, gawk factor, flair etc) so end up with 2 problems -
1) an existing incorrect unconscious response
2) a shortening of time ( due to prior experience ) to develop the new unconscious response.
phew, down off the box now
Having said all that, happy to say.
My belief from my research and experience to date is - trike are safe to fly, and my original decision was a good one. This given that they are only flown within their designed flight envelop, and in reasonable weather, with the correct training ( and for Alf - if you stay off the beach :big_grin: though if I did need an emergency landing option and a beach was available, it would be high on my preferred list).
Go for it Tomo, I know you will love it.
