Bob, As you know I have flown overa lot of water and until
family circumstances prevented it was thinking of flying
to Oz so have given this a fair bit of thought. I own a
liferaft and take one on long crossings when the water is
cold only. Would not bother just going across the Channel
in summer. There are two publications due out (one in the
upcoming GASCO mag & the other in the upcoming Europa
Flyer) which are based on a new study of the actual
ditching statistics in the UK for last 3 decades) which
show that the risks are nothing like the 'Experts' would
have you believe - in fact if you take the trouble to wear
a life jacket and carry a PLB there is only a 5% mortality
risk. If you further take the trouble to fly the plane
down to the water (rather trhan losing control & crashing)
and avoid flying in a PA28 then there are no deaths
attributable to ditching in UK aircraft in the last 28
years. You will have to wait for those publications but in
the meantime I recommend the artcle byBertorelli at:

Bruno, It is easy enough to work out next time you go
flying. Just throttle right back and measure height loss
in a timed minute at speeds around 70 kts. Or you can get
a rough answer by seeing what your rate of descent settles
out at on the VSI for a given speed and knowing that 100s
of feet per minute is much the same as knots you can
divide your airspeed (say 70 kts) by the descent speed
(say 550 fpm) to give 70/5.5 =12.7, that is a glide ratio
of 1:12.7. You may feel that you need a stopped prop to
give you a proper answer, but a stopped prop is thought to
have slightly less drag than a slowly rotating one so the
actual figures would be slightly better than your
computations. For what its worth my XS mono does around
1:12 at speeds between 65 and 75 kts. The optimum glide
angle is unaffected by weight, it just happens at a
slightly higher speed if you are heavy. So the answer to
the 2500ft Q is around 5.6 statute miles/4,9nm, further if
you turn down wind. Having said all that my advice would
be to forget about calculating such things and concentrate
on flying the plane - there are a lot too many stall spin
accidents in such circumstances!

Ilona and I regularly fly long legs over water. This year we crossed the
Skagerak to Norway, we went to Corsica via the French coast (one hour
over water), went from there to Italy and then to Croatia (also one hour
flight over water). So we have our share with flying over water.
We own a life raft... but we didn't take it with us on these trips...
Our experience is that it is impossible to take the life raft in front
of the bagage area during flight (and the actual ditching). There is
just not enough room to stow it or even hold it on the co-pilots lap
without obstructing the control column.
This implies you have to take it in the bagage area and tightly secure
it there so it stays there during the deacceleration associated with
ditching (you don't want to spoil a succesful ditching with a life raft
knocking you unconscious from behind).
Then there are two possible outcomes (not counting a total failure): the
airplane flips over or is badly damaged and sinks to the bottom. In that
case the chances to get the life raft out of the bagage area are slim.
The other outcome is that the airplane survives the ditching, stays
upright, and remains floating. In that case do you really need a life
raft? The tail or wings are probably more comfortable to await rescue,
and an airplane is easier to locate so it is a good idea to stay close
to it anyway.
Of course we have life jackets, and a PLB. We stay in contact with ATC
all the time, announce our route in the flight plan, and preferably fly
as high as possible (usually at 10.000 ft) when crossing the water so
even if the engine totally quits we still have an endurance of 20
minutes, long enough to have the rescue team already on its way or even
awaiting at the scene before we actually get into the water. (Not to
mention the possibility to just glide to the coast; from 10.000 ft you
have quite an interesting gliding range).
For just crossing the canal I wouldn't bother at all. If you fly high
enough you can make it to one of the shores from almost any point, and
there are so many boats that it should always be possible to land near a
vessel. They can either fish you out of the water or direct the coast
guard to your exact position. You are probably rescued before you even
have the chance to get into your life raft.
Oh, and I have heard that the small life rafts are almost impossible to
board, especially with clothes on, or when the water is cold (not to
mention possible injuries). You might need to practise in a swimming
pool to check how to get in and whether you are actually even capable to
do so. In cold water your strenght is gone in a minute or so, so if you
don't board fast you can forget about the life raft and use it only as a
beacon.
I'm actually considering selling the life raft.

| Subject: | Re: Life rafts in the Europa |
Frans, a thoughtful reply as always, but I would take
issue with you on a couple of points. Firstly my liferaft
sits nicely on my side immediately behind the pilot's
headrest where it is no more likely to hit me on the head
than any of the other luggage and I do not feel it
necessary to tie it down. Secondly planes sink for the
most part with the Europa Classic being an honourable
exception. PA 28s have been timed at sinking in between 2
and 3 minutes. I hope an XS would float longer but doubt
very much that it would last more than prerhaps 10 or 15
mins.

| Subject: | glide ratio XS Shortwing |
Dear David,
Many thanks for this clear explanation. 1:12 is a pretty good value. The
glide ratio of our Robin R 3000 for example is 1:9, according to the
flight
manual.
Best Regards,
Bruno

I had a similar problem and went thru the trouble shooting as you did hoping it
was a plug or wire. I narrowed it down to the electronic module itself. I sent
the module to a Rotax service center and they tested it. The module was only
firing two of the top 4 plugs. Bought a new module and all was well. $1,000 dollar
fix, ouch!

Hello Jerry.
i am not having much luck,i downloaded a diagram and found you have to remove part
of the carburettor inlet manifold to gain access in replace the left mags
Ht Leads. To change HT Leads should be a 15 minute job this has taken me well
over 5 hrs , I have heard Ratax engines are good, im not impressed so far,
as far as this components is designed its rubbish.
I can,t believe just how long a job it been. The unit should be made removable
by un doing say 4 bolts and lifting out to gain access,or even no removal at all
job done in situ.
Anyway i now have rough running on both mags,
I will have another go at it tomorrow,
Alan
