Advice please. From: "jonathanmilbank" Many thanks to everyone for your prompt and encouraging responses. As a further insight into my present operating situation, I'm the owner/major shareholder of G-EIKY and three friends each have a minority interest, but we all have equal access to the aircraft. In order to avoid misunderstandings re fuel, the arrangement we have is always to leave the tank completely full before leaving G-EIKY for the next person. Furthermore there is no fuel gauge fitted; only the vertical transparent sight tube next to the pilot's ankles. I'm a strong advocate of not putting too much faith in gauges and that the most reliable technology is your watch doing the measuring of a tank which always starts out full. This has kept me out of the "ran out of fuel" reports for over 4 decades. Having said all this, I need to find a good "rule of thumb" which the G-EIKY group members can follow to keep us out of the statistics. Perhaps only ever one person on board when flying from our airfield, which is 500 metres of soft grass (well-cut) and down in a valley? There is rising terrain when taking off on 31 and minor power cables on wooden poles to clear when taking off on 13. My arithmetic for flying G-EIKY with me as pilot is 1370 minus 860 empty weight minus 110 fuel leaves 400 lbs for me and passenger and bags. Not bad ! Take away me in flying suit being 185 lbs and that leaves 215 lbs for the rest. All the 15 years that I have flown G-EIKY like this, take-offs at mauw in 20C nil wind conditions at our field have been possible, but it's the extra rolling resistance of a three-wheeled undercarriage which now worries me. I guess that there is no magic "get out of jail free" card. We'll just have to "suck it and see". Perhaps I should make a rule which places an embargo on all take-offs with a passenger from our field whenever the headwind component is less than 10 knots. What do you think?

Advice please. From: "John Wighton" Hello, Thought l would add my opinion on this matter. I own G-IPOD a 100hp 912ULS XS trigear, empty weight 889lb. As an aeronautical engineer (stress being my specialist subject!) l pay a lot of attention to the relative performance of my aircraft to others. Having attended the Popham AGM, LAA Rally, AeroExpo, Aero, SunNFun, Airventure, etc l gathered subjective data of T/O, landing performances. As far as Europa's go, for ground T/O performance (meaning the take off roll distance) all the Europas l have seen (encompassing 80 hp mono to 115 hp superships like Frans') all appear to get off within 20-30m of each other. What happens next seems power dominated (climb rate, etc). But as far as clearing the end of a short strip l don't think you have anything to worry about (500m) at 1370 lb MAUW. Aerodynamically the mono starts off at a disadvantage (high alpha plus full flap hence high drag), the trigear with sensible tyre pressures on grass (with 15 deg flap) may even have lower drag at this stage. As the T/O alpha doesn't change a lot for the mono (tail lifts at 25-30kts?) it probably has a drag benefit during the 2nd part of the T/O run. An exception to the above maybe a 80hp trigear with fixed pitch prop, but l cannot recall seeing one of those recently. Once off the ground achieve Vx or Vy as needed and let the wings do the work. Happy T/O and landings. -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=381586#381586 ________________________________ Message 3 _____________________________________ Time: 03:28:38 AM PST US Subject: Re: Europa-List: 912ULS engine mount - loose Binx nut From: PHILLIPS I On mine i drilled a hole after tightening the Binx nut and fitted a stainless D clip to stopped the Binx nut moving, or at least migrating too far, Its a item i check regularly when ever the cowls are off, Another way is to fit a additional locking nut screwed up tight against the Binx nut Ivor On 21 August 2012 18:37, Sidsel & Svein Johnsen wrote: > Hi all,**** > > ** ** > > Just a word of caution:**** > > ** ** > > The Rotax engine ring mount is bolted to the Europa engine frame with fou r > bolts with M10 Binx nuts (the Binx nut version that is slightly oval insi de > before screwed on to the bolt, thus having a selflocking function).**** > > ** ** > > Inspecting the engine today, with both cowl parts removed, I discovered > that the nut had unscrewed itself so much that I could easily turn the nu t > and the bolt around (meaning, by the way, that the three other bolts were > holding the engine firmly in place).

I would like to understand the gravity of these ones. I see the following options: - my aircraft is grounded till repair (my current assumption) - I can continue to fly with checking if the cracks are not further progressing after every flight In order to repair, what do I need to organise? - a new cockpit module -> that seems to be a drastic repair and maybe not even possible without separating the bottom from the top of the plane - a local fix, but how to ensure structural integrity in this case? I am not the builder but can find experienced people in fiberglass work (glider repair expert). The plane is a monowheel. I got a gear up landing last year, about 20 hours ago. I see this one as the root cause of the cracks, but I could be wrong. Any advice is welcome. Jacques.

The readme file says to set the baud rate (which I think is bits per second ? ) to 38400, which I have done. But what should the data bits, parity, stop bits and flow control be set at ? I have 8, none, 1 and none at present. When I first tried to run the programme it asked me to select the com port, but whatever I selected the computer crashed and I had to reboot. Now it has stopped crashing but it says "cannot connect to serial port" every time. I have tried com 1 to com 4 on the flydat downloader, and have also tried selecting com 1 to com 4 on the com port properties advanced tab on the computer but it always says it can't connect. I'm not sure if that is because some of the other port settings are not right or because of something else. Any help greatly appreciated.
