Hi Aro, Very succinctly put - Thanks! I should not have talked up GPS rather Dynon - my EFB gives me Air Speed, True Airspeed and Groundspeed. In the not so distant past I only had airspeed and altitude, from which to estimate True. Groundspeed was based on time taken between ground points.😈

Your enturing into pretty expert territory here. Airspeed, as you climb, will be a poor indication of true speed, due to the lower air pressure (ASI working off pressure differential). The higher you go above sea level, the greater the error. In the past we used the rough estimate of 2% for every 1000 ft ASL. In a 100 knot aircraft, 2 knots error (ASI reading low)/1000 ft. Now we have GPS systems that give an instant and likly accurate readout of True Air Speed. I vaguely recall that at altitude, Vne can be easily exceeded by the unwary pilot - may have had something to do with air molecule's exciting the airframe (flutter?) -- where is that expert when needed? So it seems to me that the pilot must go by True airspeed and keep his aircraft below Vne as indicated by this system (not the ASI) 😈

Well I have been flying for a while now, very far from an expert, but I found it to be confusing and possibly even wrong in parts. Looks like you might be getting a good camber on it. Dont over do it. It may make landing on a wet surface/crosswinds, a tad more difficult than it needs to be.😈

Had a great chat with David Brown - certainly knows his Dynon (& other) systems inside out.😈

Disagree. The overwhelming focus is aviation. For the most part the few digressions are informative & entertaining. In fact it may be better to have a section especially for when a digression strays too far from aviation - that part of the thread could be transferred to reduce the "pollution" 😈

You can rely on me, to come up with a humorous typo 😈

Anyone had a read of the article on Page 78 "Airspeed" - I thought I knew about the relationships between Air, True & Ground speed - now complexly confused😈

Be careful - the company makes performance claims, without specifying which engine is being used, 100-200hp😈

Email address not good - got another?😈

Thanks Rodgerc - have emailed him😈

Having a bad trot with my ADAHRS. Wondering if anyone else in Au experiencing similar. Original (first) module worked perfectly for aproximately 130 hrs Failed without warning, on ground, on pre engine start check. Cable continuity checked and found to be good. Loan module worked perfectly for about 5 hrs - Replaced, still working, when new (not remanufactured) module arrived. No explanation from Dynon as to reason for OM failure. New module had initial problems (frozen compass) - Fixed by belated download/update New module worked faultlessly for about 4 hrs New module failed on ground, on pre engine start check. Dynon sending a loaner module, hope to install today Note: First module failure , turned whole electrical system off several times - red cross & failure message appeared each time Second module failure, as above, however each time normal screen appears but only remains for about 30 seconds, before reverting to red cross & failure message. 😈

You have given me much to think about. I have all the necessary "bits" to convert to a manual linkage, except for the cable itself. The Ultraflex B14 cable is about $100 delivered. All the wiring & switch reversing polarity system is in place, so going with plan A first. Plan A is on the way - ACTUONIX L16-30-150-12-S linear actuator. Not cheap at $98US. It's the right installed size, 30mm stroke is a bit more than I wanted, seems to have plenty of power (= 20kg extended) for operating my small flap and has 20% duty cycle which is double the Chinese offerings (Yes I realise tits probably made in China & sold by a Canadian mob). Installation should be pretty much a no brainer - alway good!😈

It may be helpful to expand on; What sort of aircraft Its current condition regarding corrosion/oxidisation Where it is located Your short/long term objectives for it Has it been treated in/out with any sort of protective substance Is it painted Is it protected from the elements - hanger, fitted cover whole/part, nothing😈

I can't remember the last time I lodged an official flight plan & SAR time. These VFR days, I just copy my flight plan, leave it with my Wife or Son. Phone when ready to depart, phone at each stop and at arrival. To me this ✔️ all the safety element boxes, with a known rout, departure, progress and arrival. I also make a call to all airfield, along my route, that I may be passing within 10Nm. Hopefully they never have to phone the authorities.😈

Blueadventures & Turboplanner Try & work through this logicly, rather than knee jerk/gut response. For a general duties police officer, with/without a gun, to prevent a crime he/she must be present at the time. I ask you how often does that happen?? Just remember general duties police, include highway patrol, marine, rail, pathology, crowd control, etc are unlikly to be tasked with being at the pointy end of a known dangerous situation. So for that one in a million chance, an officer might be in the vicinity of a crime, involving armed criminals, willing to use their guns/machetes/etc on a police officer, you arm, at a guess about 100,000, for the most part ordinary people, with Glocks. No specialist training and to be blunt very low physiological pre entry & ongoing screening. History is against you; Just a few months ago a NSW cop used his Glock on his ex lover and new mate ??? WA & Qld have very poor reputations in this area - not to suggest that the other States/Territory are squeaky clean - they are not For the most part these are ordinary people doing an ordinary, often tedious, job - you expect them to react appropriately, to that once in a career threat, when they may use their weapon - you must be joking - the shear numbers are against you. If you want guns - Arm a small, highly trained, rapid response group. They already exist, so what's the point in all those Glocks?? They just end up killing/injuring someone, who most likly could have been apprehended, without the use of lethal force. The supporters of general duties cops carrying guns conveniently forget - one day it could be you, a relative or friend having a mental breakdown, young person acting the goat and they get shot by a general duties cop who felt threatened - thats all they have to say and murder is legal. One other point - a few year back, the police asked that their already lethal S&W revolvers, be replaced by Glocks WTF!!! You arm the police, the crims are more likly to carry arms, the police want better arms, the crims get better & more arms, as if one pistol is likly to be any more of a deterrent than another - Your shot! its either an injury or your dead - you can't be more dead - we now have an arms race at taxpayers expense -- talk about insanity. Not every police force in the World is armed - Check out the British police force, to see how its done.😈

So - two attacks where no "civilian" was harmed and you think this is a good reason for arming our general duties police - I am sorry you feel so strongly about this, it seems to have clouded your judgement. No police were on hand, armed or otherwise, so they could not have prevented what happened. This is the most likly scenario, when crimes are perpetrated. So arming our general duties police, is just putting the population as a whole, at risk, especially those poor mentally disturbed individuals who may come into contact with them, without a measurable increase in crime prevention. In short an ineffective knee jerk over reaction (check out the origins of arming our police - see any similarities?). Should the criminals be found, the police response is likly to be spearhead by a specially trained and armed unit - not general duties officers. This is the appropriate response to a dangerous situaton. The inescapable reality is, that arming our general duties police has little effect on reducing crime, while exponentially increasing the risk of "legally" authorised gun killings/injury. Might make the paranoid amongst us feel safer but it's just an illusion - just like ASIC but more dangerous. "you really have no idea what you are on about" Well actually I do - have you lived through a civil war???😈

".........there are random machete attacks every day in melbourne and people murdered with them at least weekly." Odd? Our usually blood lusting media seem not to have not got wind of all that blood running in the gutters of Malborne - Could their lack of interest be something to do with being "south of the border, down......."?🤣 "cops don't just sign for a gun and walk off with it. in reality they are highly trained in firearm use." Dear BrendAn - The very fact that ALL cops are issued with a firearm, is testimony enough, to a lack of SPECIALIST SELECTION & TRAINING . It is just not credible that every general duties cop has had sufficiently in depth initial psychological, ongoing assessment & training in alternative responses to perceived threats, so that they only resort to the gun, when ALL OTHER AVENUES OF, SUBLETHAL RESPONSE ,HAVE BEEN EXPLORED ie as a last resort.😈

Years ago there was a "story" that Rotax engines were sold to the USA military, on condition that none would ever enter the civilian market ie would, after decommissioning, be destroyed 😈

"TDS is not an official medical diagnosis................However, it is currently not recognized as a mental illness in any U.S. state. " Ah! but what of the rest of the (sort of) sane World????😈

Me thinks you are lot of paranoid alarmists. (Note: I do accept the need to have a specially trained, rapid deployment, armed police group, that can respond to those, thankfully rare, situations requiring such ) How often is a law abiding Australian even threatened with a machete, let alone attacked? Seems to me that most weaponized violence is against others of a similar persuasion, rarely against ordinary Australians. A bullet is not an appropriate response, in a civilised/compassionate society, to a person suffering a mental episode - this could be you, a family member or friend. A bullet is not an appropriate response to a person high on drugs (including alcohol). So gun happy are our general duty police they have, in my memory, shot dead a; French tourist on a beach, standing in the surfe, surrounded by a half circle of trigger happy cops, no threat to anyone but himself - cold blooded murder . A young man, in his own home, having a psychotic episode, threatening to kill himself, murdered by a police woman, who shot him in the back - I think she got a promotion for this action. A demented old lady, true not by a bullet but just as deadly Taser, to a fail old woman, wielded by a delinquent clod, who should not have been allowed near so much as a toothpick, let alone a Taser - I am only surprised he didnt use his gun. Questionable executions of a number of Aboriginal people, for which no one seems to be appropriately held accountable. General duty police are just run of the mill public servants doing a routine job. They are just as prone to prejudices/fear as the rest of us - they do not need & should not have a gun. If the situaton demands - call the highly trained experts. Once you issue a gun, to all but the most highly trained/disciplined and carte blanche authority to use it - you legitimise murder. The holder, when faced with a real or imagined threat, will understandably turn to their most powerful response - THE GUN! rather than seek a more nuanced solution. What of the young police ambushed by a small group of religious' fundamentalists? I hear you say - The police were armed - did them no good. It's possible that if the weirdos knew the police were not armed, there may have been a very diffrent outcome - we will never know. It seems that ASIC is not the only political knee jerk reaction, to what was likly a one off incident: "In 1894 as a result of the Bridge Street Affray, a number of Police in Sydney were injured while attempting to arrest a group of safe-breakers. Parliament subsequently passed legislation authorising the arming of all members of the NSW Police Force and all Police have carried firearms ever since." 😈

"I think you should re-read my post as I was using it to support your position" Yes and I thanked you for that. However as you continued, I felt that some of that support had been undermined/lost. "And yes, the gun analogy in this context does work because, including yourself, people assert ASIC didn't work in this case; as it transpires, neither did the gun laws." Obviously I do not agree. As for the gun laws; I think they do work. The buy back policy removed a staggering number of guns from our society. The presence of these guns, just made them more accessible to the bad people, removing them less so. That it took the likes of Martin Bryant to bring about these laws is a tragedy. Having a firearm is a privilege (much like flying) that now requires some training, justification and licensing - all good. Licensing means that legal firearms & their rightful owners are traceable , delivering some degree of control. No law will prevent bad people from doing what they want, at best it will make the pursuit of their nefarious activity more difficult. Having fewer firearms in the community may reduce opportunistic violence and accidental injury/killing, especially of/by children. Requiring firearms & ammunition to be responsibly stored, adds to the above point There is no justification for a private person having a firearm that is designed specifically for the killing of people ie machine guns and pistols. Personally I am against general duties police carrying firearms - there is no good argument for this. It leads to is the unnecessary death of mentally disturbed people, who for the most part are a threat to themselves, rather than to the police or the public at large (way too many tragic examples to list). 😈

This Forum is excellent - Unlike some other forms I am on: Great feedback (for the most part) Great debates, that rarely descend into personal attacks Good people, nearly always willing to help, no matter the topic/question Fantastic tangential departures (Thread Drift) Enough "gush" safe to say I regularly recomend The Forum to fellow pilots😈

Good one! I taught the Forum was part of /connected to Sonex, so contacted them - Apparently no direct relationship and they are also unable to access the Forum.😈

Anyone know why the Sonex Builders Forum has gone "off-line"? Could it be a Trump inspired export embargo to the rest of the World?😈

Sorry! worded badly My position is simply - A country that invests in the education & health of its citizens, is investing in its future. The USA is the opposite of this. For about 20 years now, I have expected the United States to disunite. It has been been subject to huge social pressures for quite some time. The rise of Trumpism may just be the last straw😈
