  1. The instrument will consist of two parts. the sender, which you have mounted and the display. There are several different senders on the market and I do not know which is used by Navman, but they all work on the same principle of counting pulses. There is probably a toothed wheel turned by the flowing fuel and the sender counts the teeth as they pass a sensor. The fact that the total fuel use is OK, but I assume you are saying that the litres per minute is incorrect, says that the sender is working OK. Maybe the problem is due to vapour in the line. That would stop the pulses and then later increase them. The fuel flow would stop and you would be running on fuel in the carbie bowl, then suddenly it would flow at a high rate.. I am in the process of fitting one to my plane and haven't calibrated it yet, due to having to repair a leaking fuel tank.
  2. They counted each flight and compared it with the number of flights done by the rest of GA. I don't know how long the average Angel Flight flight is but I am sure it would be a lot longer than my average flight. A quick look at my MR for the Corby shows 413 hours and 1023 landings. 25 mins per flight.
  3. If you flew along the equator at 900kts in an Easterly direction you would not really need time. Just every 24 hours you could change the day. That means no watch necessary, just a calendar.
  4. Unlike a lot of beaches that one appears to be hard right to the top. Where I fly they can be really soft above the damp area, very hard to taxi and turn around in the soft stuff and a friend of mine earned the nickname "Flipper" through trying to use the soft stuff.
  5. Stainless steel is used for aviation, but not in the 1/19 format. The finer strands used are capable of bending safely and if you get one broken strand that tells you it is time to discard the whole length. I replaced my SS control cables last year, due to the CASA requirement to ditch the terminal ends at the turnbuckles. Cables were perfect after 15 years of use. CASA then changed their mind and allow inspection, rather than replacement. I don't think there is any requirement to use SS for lockwire, Gal is acceptable.
  6. Thanks professor. Not Roly Sussex. To add to the nautical scene it seems like drudgery, and it has been a few years since I drudged.
  7. The one thing we cannot control is that plane coming in flatter than us and faster. If I am in the circuit with a Dash 8 he will be overtaking me from below, as would a Mooney. I am not happy with that scenario as I know the faster planes pilots should be able to see me, but they could be fixated on the touch down point and not looking above or even at the same level. Radio is a great help here and most of the times would be in a radio environment. This stems from an experience I had at Moorabbin many years ago when a low wing plane came out from beneath my Victa on the approach. He called up to ask if I was for runway left, which should have been obvious as I was aligned with it.
  8. I wondered what the definition of Trolls was
  9. The Lycoming engines are prone to camshaft corrosion if not run regularly. I would assume Jabiru would be the same and probably Rotax if the camshaft is above the crankshaft. I have never had water in my fuel tanks, but I do try to keep them pretty full. I have seen engines with the dipsticks showing white foamy liquid instead of oil, due to water in the oil. Luckily not in aero engines. Another way to damage your engine is to turn it over to supposedly spread the oil around. It doesn't get enough turns to produce oil flow from the bearings, but it is enough to scrape the oil off the camshaft and cam followers.
  10. I have always liked straight in approaches. I can cut the power at 5000' and glide all the way to touchdown and have done so many times, but the danger is in relying on wireless to find who is in the circuit. If you don't hear anyone in the circuit, that is a good start, but then you have to keep a really good lookout. Most of the traffic will be in front of you at the start of your approach, easy to spot, especially as they will be below you and stand out as moving objects. As you get closer the risk comes from the live side of the circuit and increases greatly. Here is where the goldfish bowl canopy of the Corby or RV really shines. The really hard aeroplane to spot is the other one also doing a straight in and in my case I would most likely descend onto a faster plane. That plane should be able to see me, but I wouldn't guarantee it. Especially if it was a C182 or something similar.
  11. Boeing are now re jigging the computer programs so that both computers will compare notes. It sounds as if Boeing is being taken over by Windows. It certainly doesn't impress me. It was ridiculous to have the computers look at one AOA indicator when there were two on board. Even the most ignorant programmer could have seen the problem.. Now they are raising the question of chips being hit by cosmic rays and changing computer ones to zeroes. Maybe they should take up fishing as that looks like a red herring to me.
  12. I don't like that idea of descending from 1500 to circuit height on downwind. I think the correct way is to overfly and descend to circuit height on the dead side, join downwind at 45 degrees. That way you will not descend onto someone else. I once joined the circuit at an airstrip and was on mid final when the owner of the strip shot in front of me and turned final doing a right circuit. He had decided to do right circuits as it kept him away from a skydiving mob at another strip. His radio wasn't working. He got quite a surprise when I passed him on final and landed half way down the strip. I was in the Corby and he was in a Zenith STOl type.
  13. I do a days work outside and after that I look at the news on TV. Change to one time zone and I will probably have to se the news before I want to knock off work. We have had a similar idea in Qld, where the South East corner want to go onto NSW time in Summer. Doing that will result in kids getting up in the dark to go to school and coming home in the hottest part og the day.. I just wouldn't work. Across the Nullabor the towns use different times from SA and WA to make life easier.

    Stalls

    One of the first things I like to do in a new to me aircraft, is to do a straight and level stall. That gives me information on how to conduct the rest of the flight. I have read tales of first flights of new planes being done without approaching the stall and that to me is foolhardy. It is nice to be able to perform a falling leaf, safely in a plane and I find it enjoyable, but I am not so happy nowadays with spins.
  15. I had a problem with what I thought was a turbo wastegate control on my 4WD. It went into a garage for work on the brakes and I asked the mechanic to have a quick look at the waste gate operation. He couldn't see anything wrong but didn't remove anything to get a real good look. I then looked and found a plastic bag, partially blocking the inlet. So have a look at the air cleaner and inlet.
