View Full Version : Visit to Poland and test flight

I visited the Xenon factory in Poland on Monday

Ralph Celier and his colleagues could not have been more charming.

I, my son and an instructor friend (microlights three axis, trikes and hang gliders) travelled together.

There were over half a dozen machines in various stages of construction including one crated and ready for shipment to Australia.

I am not qualified to talk about mechanical details or design but the machines looked beautifully finished. It was quite clear how methodical and careful was the approach to each task.

All of us took a test flight with Ralph Celier, again without being a gyro pilot I can not compare the performance characteristics to that of other gyros. Ralph let me take the stick for a couple of circuits and the machine handled as smoothly as any three axis fixed wing. With power down it descended gracefully and in the climb it rose nimbly.

There was a little vibration in the stick but not much more than what I experienced the two or three times I have been allowed at the stick of a helicopter.

I am 6'3'' and my son 6'4'' we had no trouble getting in or out of the aircraft and it was truly comfortable to sit in. The door hinges might be a little vulnerable in high winds but Ralph is planning to fix this with a gas strut. The only fault I could find with the interior decoration was the seat adjustment mechanism - while its certainly quick to adjust and secure when belted in, there is a risk that when climbing in or out of jeans or jacket catching and pulling the seat out of it's position. I would prefer a split pin or the like to fix the seats more firmly. Slower to change but when only one pilot flies the machine then preferable to fiidling to put it back in place if accidentally moved.

My only regret is that the Xenon is yet to be certified by the UK CAA - Ralph assures me that he has the matter in hand. Having had a lot of dealings with a wide variety of government departments I realise that with the best will in the world getting permits can take a lot longer than planned. If and when certification comes through I am very tempted to buy one.

One question if i may, What do you mean by certification?
What type of certification as you meaning?

Damn that is 2 questions but you know what i mean :lol:

The biggest challenge may be the aluminum (aluminium?) mast. As far as I know that is not allowed according to section-T.

No problem with mast material for sec T !

Aircraft in the UK are regulated by the Civil Aircraft Authority (CAA).

In order for a Gyro to fly legally it must now conform to "CAP 643, British Civil Airworthiness Requirements, Section T Light Gyroplanes"

The full text of the documentis available here:
http://www.caa.co.uk/application.aspx?catid=33&pagetype=65&appid=11&mode=detail&id=169

Interestingly it was the CAA that commissioned the University of Glasgow study into gyroplanes that resulted in CLT paramaters being mandated and one might guess indirectly a contributor to the "flame wars" over CLT

For more information on the certification process in the UK - you might consult the CAA website.

Nice reading:

http://www.caa.co.uk/docs/33/CAP643.PDF

Especially:


Longitudinal, lateral or directional oscillations with controls fixed or free and following
a single disturbance in smooth air, should at least meet the following criteria:
a) Any oscillation having a period of less than 5 seconds should damp to one half
amplitude in not more than one cycle. There should be no tendency for
undamped small amplitude oscillations to persist.
b) Any oscillation having a period between 5 and 10 seconds should damp to one
half amplitude in not more than two cycles. There should be no tendency for
undamped small oscillations to persist.
c) Any oscillation having a period between 10 and 20 seconds should be damped,
and in no circumstances should an oscillation having a period greater than 20
seconds achieve more than double amplitude in less than 20 seconds.
The disturbance should be introduced, with the gyroplane in trimmed steady flight
and with the other primary controls fixed, by moving one primary flight control [to an
out-of-trim position in one axis sufficient to change the attitude of the gyroplane by
approximately 5 degrees] and immediately returning it to its original trim position, at
which it is then held fixed.

Hi,

Yes I confirm, we are in the process for UK certification with the help of our new distributor. More soon...

Our new UK XENON distributor is AMT Group - Michael Crane - 00 44 78 50 16 67 16 you can call him directly to talk about details. They are based in airfield 10 miles from center London.
They know very well the factory and have also flown our XENON XL
Kindly

Thats great thanks, any idea of timescales to the xenon being granted uk certification?

They answer is from 6 month to 12... hard to deal with CAA. We will keep everyone posted for any progress. We already have definitely many many customers ready...
We have currently one legal solution is to register the machines in Ireland where we have permit to fly, then fly them in England with renewable limited permit to fly...
Contact AMT Group.

You will have to be resident in Ireland or a Eu citizen who resides in Ireland.
Also the new Xenon has to be approved.

Raphael,
Are you getting my e-mails? It is very important that I talk to you.
