  1. About time the Victoria Police caught up to the NSW Police, who have had drones for ages, except they are not called "drones". They are called Commissioned Officers.
  2. This from the Belfast Telegraph: Aer Lingus Introduces All-Leprechaun Flight Crew. Former Aer Lingus trouble shooter, and current QANTAS CEO, Alan Joyce praised the move and lamented that no suitable types were available for Australian airlines to hire.
  3. As long as you have the 'gear' you'll be OK. But watch out for crackheads passed out on the runway.
  4. Thread Drift Alert! Back when I was annoying motorists on the Hume Highway, some of my colleagues would waterproof the speed radar unit by putting a condom over it when there it was misty or raining. I remember one of these blokes as being of relatively slight build. You can imagine the snickering after he left the chemist's with a couple of extra large condoms.
  5. I recently watch an episode of Selling Houses Australia in which the property was a former railway crossing keeper's cottage. Obviously it was right beside a double track section that carried both regular intra and inter-city passenger traffic and intercity freight traffic. The intrusion of the railway noise into the house was a negative selling factor. As part of the spruce up to sell the property, they installed what is called "secondary glazing" on the windows on the railway side of the house. After the fitting, the noise of the trains was virtually eliminated. Here's some information about soundproofing by glazing: http://blog.thermawood.com.au/soundproof-windows-cost However, I can live with the regular drone of an aero engine, but not the racket made by the Doof-Doof crowd's cars and bikes.
  6. Et talis emptor rem non satis est quaerere quaestiones: tum quia anathema patiatur ob segnitiam If the buyer does not ask enough questions, then let him suffer for his indolence
  7. Whatever happened to caveat emptor? You don't try to establish a meditation centre beside a rail shunting yard, and you shouldn't develop residential land adjacent to the extended centre lines of runways and expect the sounds of silence. What gets my goat is that these newcomers complain about aircraft noise, but say nothing about the noise from motor vehicles with dodgy silencing systems, or emphysemic turbochargers. Consider this. The pilot of an aircraft taking off has the required power setting in place about an eighth of the distance into the take off run, and maintains it to at least 1000" (approx 300 metres). Therefore the noise that the engine makes is constant to at least 300 metres altitude and then it is likely to reduce. However, Harry the Hoon, in his V8 ute with non-standard muffler system can be heard revving the t!ts off his engine up to a kilometre away, even in residential areas. What's worse? The occasional overflight giving rise to a constant hum, or frequent intermittent high decibel screams from motor vehicles? Come to my place any weekend and see which causes the most disturbance.
  8. For those who refuse to believe in God, the human psyche requires something in God's place.
  9. Even fewer pressurised bulldozer owner/builders.
  10. Which is the better system for recording an aircraft's Total Time in Service (or pilot's flying time for that matter)? There are at least two ways of recording an aircraft's TTIS - Tacho time or Hobbs Meter time. Although aiming for the same target, the two methods record different things. Tacho time is a recording of the time an engine has been operating. It is linked to engine revolutions per minute (RPM). Tacho Time records the time at some specific RPM. It is most accurate at cruise RPM, and least accurate while taxiing or stationary with the engine running. At these times, the clock runs slower. That might be an accurate measurement of wear and tear as one would expect the engine components to be less stressed around idle speed. Hobbs time is time recorded by an electrically powered clock. The Hobbs meter can be activated in a number of ways: It can measure the time that the electrical system is on. This maximizes the recorded time. It can be activated by oil pressure running into a pressure switch, and therefore runs while the engine is running. It can be activated by another switch, either an airspeed sensing vane under a wing or a pressure switch attached to the landing gear. In these cases, the meter only measures the time the aircraft is actually flying. With method 2, the Hobbs reading will be closest to the Tacho time, but will always be higher because of the slower reading rate of the Tacho when the engine is at low revs. With method 3, the Hobbs meter records the time that the airframe was subjected to in-flight forces. With method 1, leave the Master turned ON when you hangar the plane and your maintenance period will be short, without any flying being done. What is the best way to record TTIS to balance the needs of good maintenance and economical running? Each method introduces inaccuracies. Perhaps the compromise is to wire the Hobbs meter to the oil pressure switch so that Hobbs time and Tacho time are more closely aligned. The Hobbs meter will account for the under reading of the Tacho on the ground to account for engine use, and allow for structural wear to the airframe during movement on the ground.
  11. Another example of accurate reporting. Fire?
  12. Be careful of buying a Cherokee without going into its airframe maintenance. y now, every Cherokee owner, from the earliest PA-28-180 to the most recent Arrow, has heard about the inflight wing separation that occurred April 4, 2018. https://www.piperflyer.org/maintenance-technical/item/1161-pa-28-pa-32-wing-spar-cracks-what-you-should-know.html The FAA published Airworthiness Directive 87-08-08, only 36 days after the wing separation. Aircraft with less than 5,000 hours total time in service (TIS) had to comply before reaching 5,050 hours; aircraft with more than 5,000 hours TIS had to comply within the next 50 hours of flight time. The AD required that both wings be removed. Complying with this AD is expensive, so factor that cost into a purchase price. If the inspection finds cracking you will be up for a new wing, and a 2nd hand one still has to pass the inspection before it can be fitted. In applying "What's good for the goose is good for the gander", it would be a good idea to inspect wing attachments on any aircraft you were thinking of buying, especially if the TIS is getting high.
