[color=red:f3ed5c1dbe]QUESTION TO OWNERS OF A EUROPA TRI-GEAR EQUIPPED WITH A
ROTAX
912UL ENGINE[/color:f3ed5c1dbe]
[size=9:f3ed5c1dbe]Others: don't even bother to read this, you have other
interesting
things at hand I might hope :wink:[/size:f3ed5c1dbe]
The last couple of months I have been quite busy looking to buy a ready Europa,
which last week resulted in me having bought the G-BWON, a 1997 Classic Tri-Gear
currently owned by David Joyce and Bob Hitchcock. The G-BWON is equiped with
a Rotax 912UL with just over 300 hours on it.
In the OPS manual for the ROTAX 912UL there is a table showing the relation
between
engine power setting, engine speed, performance, torque and manifold pressure
(in 10.1.1)
Unfortunately I can't show HTML tables here, so I will have to go with what I
can
do: the following lines show an extract of that table, the fields shown are:
[b:f3ed5c1dbe]Engine Power Setting - Engine speed (rpm) - Manifold Pressure
(in.Hg)[/b:f3ed5c1dbe]
Take off performance - 5800 - full throttle
Cruising power - 5500 - full throttle
75% - 5000 - 27.2
65% - 4800 - 26.5
55% - 4300 - 26.3
[color=blue:f3ed5c1dbe]What I would like to find out in preparation for the
ferry-flight
---From the UK to Holland, are the [b:f3ed5c1dbe]realistic[/b:f3ed5c1dbe]
numbers for [b:f3ed5c1dbe]fuel burn[/b:f3ed5c1dbe] and [b:f3ed5c1dbe]indicated
air speeds[/b:f3ed5c1dbe] that go with these numbers.[/color:f3ed5c1dbe]
Highlighting 'realistic' is because from experience I know that in general the
real numbers turn out to be somewhat more 'negative' than what is listed in the
manuals.
Also, flying the 2nd leg of the ferry (EGMH-EHHO) with two 200lbs+ people
on-board
limits the amount of fuel to just about the theoretical 'can-do' with a 30
min. reserve and wind coming from the 'wrong direction'.
Not having sufficient assurance that the numbers I used for this planning (16
ltr/hr
@ 115 KIAS), I feel this planning is just too tight (also at the time of
the ferry my hours on the plane will be very limited).
I am therefore looking for as much input on the subject as I can. I know I could
fly @ 97KIAS for best economy, but speed is of essence to do the ferry in one
day, so I would really like to do it with 110+ KIAS.
Therefore my question:
Would you please share your real-life fuel burn and air speeds that go with
above
numbers, so that I can better judge whether I should insert a 2nd stop about
halfway Manston - Hoogeveen.
Thanks in advance!
