Once you apply the temperature (say 40.5 C like yesterday in Canberra or 45 C possible in Leeton) and a high pressure system corrections how high can that airfield get? What would that do to the landing and takeoff rolls of a MTOW passenger plane or for that matter a typical RAA plane fully loaded? So far the highest point I have landed on has been Ballarat. Regards

A story I heard a couple of days before Cristmas from a construction worker who works in the New England area of NSW for a civil engineering contractor. A controlled aerodrome has recently had a security fence built around it without consulting the pilots. The pilots using the strip subsequently inspected the fence and decided it was a risk they could not tolerate as it was too close to the end of the airstrip and was higher and more substantial than the ordinary boundary fence. It was not stated whether it replaced the original boundary fence or was well inside it like some others around the country. The innovative solution! Remove the offending section of security fence; on the same line dig a v-ditch as deep as the security fence was high and erect a new security fence in the bottom of the ditch. It reminds me of a jet plane photo I have seen that failed to stop on a runway and ended up with its nose in a drainage ditch. I was unable to verify this story as I drove past the aerodrome as I was distracted by the sight of a large grey coloured twin engine jet plane on late final and landing! Besides I had not heard the story at that time!

The Jabiru construction book specifically mentions to keep silicone away from the fibreglass. :;)1: Regards

The AGM of the Leeton (NSW) Gliding Club was held on Sunday 17-12-2006. About 27 new members (mostly old) joined up to support flying in all its forms. Possibly there will be a name change for the Club some time in the new year after the Junior Gliding Competition that startsjust after the new year. People attending the meeting included some from Leeton Griffith, Narrandera,Whitton, Wagga Wagga and Lochart. The A/C types that attendees (now mostly members) fly includedRAA, SAA, GA, Ag AC and GFA (sailplanes). Regards

Hi Danda I don't go over to Narrandera very often (or anywhere else)but I have seen a number of satisfied people there who have come a fair distance by car to be trained by Wally. Ones that come to mind late this year were from Ivanhoe, Canberra and Wollongong plus of course people from all around this area. I should go to Narrandera rather than Griffith as it saves me over almost 70 km for the round trip. I mainly did my Jabiru training at Griffith because they had a new Jabiru 2200and I was in the process of buying a Jab J160 kit. Now I am getting my endorsement if you like for the Tecnam with Wally. He asked me if I wanted to go as PICyesterday but I thought at least another session with him was more appropiate. I was feeling a lot more confidant in the Tecnam after almost an hour of circuits. Regards Ross

A sample of a small label on the back of a Nokia phone battery charger wherethe small lettering is less than 1 mm high. [ATTACH]445[/ATTACH] The photo was taken without flash just a desk lamp with a Panasonic DMC-FZ5 digital 5 megapixel camera setfor macro shots with the medium resolution JPEG photo setting and about 2X magnification. It still has the TIF settingto go which produces bigger files I don't hnow about the detail! The resultant Jpeg photo was cropped down to about 1/9 th of its original size before posting to the forum. This camera has 12X optical zoom equivalent to a 35 mm SLR with 36 mm to 432 mm zoom lens. And it is out of date - the later models have higher resolution and also include anti shake feature as does this one. They have come a long way in the last couple of years. Apologies - I just noticed the topic here is supposed to be daylight saving. So if a camera topic is started perhaps this post could be moved to it if an admin person has the time & thinks it is worth it! Otherwise delete this post. Regards Ross

Hi Geoff I get checked out in Wagga on 5-01-2007 then I will know more. Regards

At Narrandera today 20061216 I had my second flight sessionin Wally Rudin's Tecnam P92after he did some running repairs. Wally had to tune & match the twin carbies after replacing some throttle springs - do not get it right and it sounds like a jack hammer. Wally had it really purring by the time he finished. [ATTACH]1103[/ATTACH] [ATTACH]1104[/ATTACH] While I was waiting for my turn to fly second in line after the repairs there was another local from Leeton that flew in. We do not have a sealed strip at Brobenah or Jet fuel (or any other fuel). [ATTACH]1105[/ATTACH] The Tecnam panel is arranged a bit differently from the panel below in theJabiru that I trained in and hire periodicallyand am used to flying and probably is a little different from the A/C above. [ATTACH]1106[/ATTACH] [ATTACH]1107[/ATTACH] Jab 55-3917 living at Griffith NSW (YGTH)is fitted with an engine driven vacuum pump to power the vacuum powered instruments. One of the really big differences from flying the Jabiru is the down view from the P92 Tecnam over the nose so much so that the Jabiru flyer Tecnam novice like me is in danger of stalling the aircraft in the landing pattern because I am not used to having the nose so low. It really gives a great view forwards and below. You really have to be aware of it and keep that speed up. The view in the turn is not so good but I believe is improved in later models from this particular one. Conversly in the Jabiru I tend to fly it too fast because of constantly wanting to lower the nose to see where I am going! There was a mid air collision in the gliding competition at Leeton some years ago as a Club Libelle (fibre glass aeroplane)pilot virtually "ran over" for want of a better description anotherglider (wood and fabric covered)while going through the start gate ( a square kilometre in the sky with its base on the airfield). I saw what was left of the second aircraft a few seconds after the collision as I was taking some household rubbish to the Leeton tip which was on the western edge of the airfield. It had virtually exploded once it's fabric was ripped open in the collision. I must have heard the noise of the collision as I was only about three hundred metres from where the pieces landed. So I had looked up to seeone pilot hanging froma parachute and a great host of small pieces of aeroplane falling gently to earth. The Club Libelle pilot decided he was going to jump and undid his seat belts and then changed his mind and decided to land on the airfieldnot far from the club house which he did without injury. After landing he discovered that his seat belt was still undone. It is not unknown for glider pilots to be bounced out of their seats straight through the canopy or to be knocked unconscious by the canopy. So they never undo their seat belts in flight unless they want to get out! The parachute pilot only suffered minor injuries but probably walked halfway back to the club house before anyone was aware it had happened. Regards Ross

It looks good Geoff - getting near the end and the beginning of the next stage - the security staff seem to have tossed in the towel. What does the "Smart Tool" do. Went over to Narrandera today and metChris from Wollongong about to return (drive)to the Gong after a week under Wally Rudin'stender mercies in the Tecnam. Regards Ross

Don We did have some fires in those hills lit by one of the passing electrical storms last week I think it was. But I think those fires are pretty well under control now.This smoke yesterday was largely from the Vic fires fires I think, but maybe the prevailing weather system on the east coast could havecollected smoke from all the fires in the eastern states mixed it up and really spread it around.

Hi Crew Leeton visibility from my carport mid-day yesterday 20061212 & 10 am today 20061213. The trees and houses in the distance are about 350 metres North East of my house. [ATTACH]1216[/ATTACH] [ATTACH]1217[/ATTACH] The trees and houses are about 350 metres North East of my house. The Brobenah Hills on the horizon are the hills behind (East of) the Brobenah aerodrome at Leeton. The Brobenah aerodrome is about 2.9 Nautical miles North East of my house in line with the photo roughly. The Brobenah Hills on the same line are about 4.15NM from my house. Thursday morning 20061214below started with calm air and smoke till about 13:00 then became dusty wind from west. Photos below were taken about an hour apart 1st one with smoke the second one mostly dust. [ATTACH]1218[/ATTACH] The red brown colour of the dust is not showing very well in the photograph below. [ATTACH]1219[/ATTACH] The two Picsbelow for Friday Dec 15 are the same photo but the second one is enhanced to show up the remains of what might be not very well defined early morning vapour trails. From here I think that we canoften see parts of Gold coast to Adelaide trails, Gold Coast to Melbourne, Sydney to Melbourne, Sydney to Adelaide (almost over the top)andSydney to Perth. Sometimes we can also see to the west what looks like part of Darwin to Melbourne. It has to be a very clear day to see the Sydney to Melbourne trails usually mid winter. [ATTACH]1220[/ATTACH] Photo above enhanced below to show up trails or cloud [ATTACH]1221[/ATTACH] The sky to the south today 20061215 is looking dull - possibly smoke. Ross

Geoff I see that you have been let back in the lounge room unless you have a doily and clean carpet in the workshop. The detained suspect looks a bit like a red from under the bed - I can tell 'cos he has a fixed almost 1000 yard stare - not shifty eyed at all - his pupils are almostfully dilated so he's probably on drugs as well.

The site for the "E.A.R.S.2" was www.avshop.com and the price was $US100 or just under and it requires the lead for the cell phone to be matched to the adaptor just like the "Flightcell 2Go". No doubt some phones will not require a special adaptor lead and will use their standard chord just like the Flightcell 2Go. Ifound that Flightcellhave a listing on the web of about 175cell phones by brand and model indicating if an adaptor is needed and its' Flightcell part number and whether it is available. The list was last updated on 1-11-2005 so only one of the current or old CDMA phones thatI ownis on that old non current list. They indicate on the bottom of the list that there are more - so they supply a matching adapter when they supply the Flightcell 2Go. Only sixof the 55 older Nokia cell phones listed did not require an adaptor between it and the flightcell 2Go. Only six of the 22 older Motorola cell phones listed required an adaptor between it and the Flightcell 2Go. The Flightcell 2Go price is $A315 from Wadair one of the Australian suppliers for either ofthe mono and the stereo versions. Flightcell also have a special model. I think it is Flightcell Pro V6 for around $A704 that is much more capable with many progamable optional inputs. They suggest it suitable for emergency services where there are many other systems to cope within high noise environments where it would be a big advantage to use a an aviation style headset.

Thanks for that Geoff. I shall have to price the the SS heater. I had to get my steering rods shortened and rethreaded because they were too long and I am only about 5" 10" Regards

Hi Geoff I like the look of yourmetal cabin heater although if it is made of pure aluminium the melting point is about 660 degrees C.Plain carbon steel is about 1400 degrees C. I had to look them up in my1963"Machinery's Handbook 16th Edition". That might beabove a fuel fire temp of about 1000 degrees C. Is the cabin heater epoxied onto the firewall? The body of the cabin heater supplied to meis fibre glass so I have not installed it. I don't like the idea of a possible blow torch like fire applied to the fuel lines on the wrong side of the main fuel isolating valveor onto my feet under the instrument panel. I shall have to investigate the metal one. Are you going to install any soundproofing on the back of the firewall? Mine has a layer of foam glued to the back and then a layer of felt glued to that making it a little more difficult to add extra things through the firewall. But the soundproofing compressed easily with the fibreglass panel pulled into it withthe bolts through the firewall which also adds a bit more security to the attachment of the stainless steel firewall. Setting up the steering rods tothe rudder pedals so they clear the firewall and coordinating that with the rudder offset is a bit painfull as all the rods have right hand threads on both ends. They also move vertically and horizontally when activated trough the firewall!You have to disconnect themfrom at least one endto change the length. One advantage to this is that if they come loose the length does not change unless they actually undo at one end! I found the rudder cable movement marginal making it very tedious to get all the movements and stops set correctly as there was virtually no available adjustment. To check the rudder movement, I placed an L shapedpiece of light gauge tin plate under the rudder with the long leg horizontal up the side of the vertical stabiliser. The hinge point is roughly at the bottom of the right angle formed by the sides of the L. With a pencil I marked on this plate the position of the rudder when against each stop and also in the neutral pedal position which is offset from the zero rudder position. So I ended up with a plan view of the rudder movement compared to the longitudinal axis of the aeroplane. ThenI could readily measure the angle of movement of the rudderbetween the lines drawn on the plate and the angle of the offset.It seemed far easier and more accurate than the method described in the construction manual and you can do it in comfort standing on the floor! There should be no load on the cable when the pedals are on their stops and the rudder is on its stops. This is difficult to check on your own - you need very long arms! If I remember the numbers correctly from the"J160 construction manual" itspecifies 20 degrees movement of the rudder each way but it does not specify if this is from the neutral position or if it is from the 5 degrees offset position of the rudder! Regards Ross

Fantastic! Great work Geoff. How much sleep have you had in the last couple of days? May all your ploblems be very little ones for the rest of th project! I cannot see much sign of the security staff! Regards

Geoff I can tell you that the Mini Minor did not have anything like the acceleration of the Mini Cooper but it wore out a lot of rubber - on the front tyres. Regards

What is the effect of solar flares on magnetic compasses and electronic or digital compasses? Regards

A big step well done Geoff. She looks great. How many top coats did they put on? Where are the security staff? Regards Ross

Hi Crew If you look at my previous post you might notice that I said I had installed AVG free edition version 7.5 (a few weeks ago I thnk it was). Regards

I don't seem to get any spam nowadays. I am not really sure what I have done to get to this desirable state. But here are a few suggestions. I run two antivirus programs 1. Nortons Antivirus program with daily auto updates - runs on a yearly license scan of incoming and outgoing email periodic scanning of the whole system 2. AVG free edition version 7.5 dailyauto updates scanning of in and out email (turned off because it is slow) auto dailyscan of whole system every day (but you can stop it) The non free version of AVG has more options and I do not know the price. Auto daily microsoft updates-which mainly cover security of the system. Go to Control Panel Pick the Security Centre Set Firewall ON Set Automatic Updates ON Set Virus Protection ON If the protection is causing too much extra button pushing to make programs go to the next step in the Windows Firewall Exceptions and add the names of progams to be exceptions. I have listed a number of programs like the antivirus programs the various auto-update programs that run on your computer for the Microsoft updates and the antivirus update programs. I also add the various programs that Quicken runs for getting ASX share prices. There are a number of other internet settings which I have foregotten that raise the default barriers against pornography. I have not seen a ad for any kind of sex aid for ages - touch wood. A year or two ago I was getting twenty or thirty of them per day. Turning off the preview on emails (although inconvenient) will protect you against hidden problems in unwanted emails. Previewing emails is actually opening the email and exposing you to the any hidden junk in the email. I leave my email preview turned on, a risk, but I am not getting the spam mail to make it a problem. Regards

Hi Geoff Best of luck for the rest of it. The bear does look fairly resigned to the paint but will probably be much happier after Wednesday night. I used combinations of small boreslightly flexible electrical conduit and about 12# tie wire to aid pulling or pushing wires and control cables through the fuselage. This wire is heavier than the wire sold in small rolls in hardware shops. It is usually used to twitch barbed wire to the top of "star" posts in ordinary farm fences and is easily bent by hand. The tie wire is thick enough to be pushed through the length of the fuselage and would probably work along the length of the wings ifanybends are not severe. I usually bend over the end of the wire so that it presented a smooth end to any obstruction like a lump of stray epoxy or a sharp edge. Regards Ross

Geoff it looks good and the bear will be obvious when he leaves that spot! Regards
