  1. On a standard glide path for a jet-powered passenger aircraft, the descent typically follows a 3-degree glide slope, which is a standard approach angle used at most airports worldwide. Calculating the Distance A 3-degree glide slope means the aircraft descends approximately 300 feet per nautical mile (nm). Given the altitude of 750 feet, the aircraft's horizontal distance from the airport can be calculated as: Distance=AltitudeDescent rate per nm=750300=2.5 nm.\text{Distance} = \frac{\text{Altitude}}{\text{Descent rate per nm}} = \frac{750}{300} = 2.5 \, \text{nm}.Distance=Descent rate per nmAltitude=300750=2.5nm. Conversion to Statute Miles 1 nautical mile is approximately 1.15 statute miles, so: Distance in statute miles=2.5×1.15≈2.88 miles.\text{Distance in statute miles} = 2.5 \times 1.15 \approx 2.88 \, \text{miles}.Distance in statute miles=2.5×1.15≈2.88miles. Conclusion At 750 feet altitude, a jet-powered passenger aircraft would typically be about 2.5 nautical miles (4.6 kilometers) or 2.88 statute miles from the airport, assuming a 3-degree glide path. So, nothing to see here.
  2. Not at Heck Field i hope ! We, the originals, are getting sick of all this rubbish happening!
  3. Good Luck ! Hope you get market acceptance.
  4. and whats the problem with that ? Foreflight is really good (and similar)
  5. Reminds me of a fairytale about "the sky is falling"
  6. How could the "72 year old" still be a captain for Qantas ? Way past retirement age ?
  7. They didn't take it over, it just changed its name to represent the new types of aircraft available so they removed the word "ultralight" from their name and replaced it with aviation. There was and is such a stigma over the word ultralight. The media love to use that word to describe crazy people flying aircraft made from stuff you buy at Bunnings with a lawnmower engine on the front (or back). Anyway it was just an evolutional it wasn't a takeover or anything nefarious
  8. it won't make any change to the volume of the intercom it will only adjust the volume of the sound you hear when you are talking. You could just get used to it and leave it as it is or change it about halfway and hope the other owner doesn't notice
  9. it's going to relate back to the radio or Intercom that you have installed, this is what controls the side tone. Please give us more information about your particulate set up and we might be able to give you some direction, radio, intercom etc
  10. if the volume seems low it has nothing to do with the headset itself. It is to do with the side tone from your radio or your Intercom. You should be able to adjust this and ideally you want to match it to the Intercom, the side tone and the received transmissions so that they are all balanced
  11. The problem is there are very few forum menbers left here. ☹️
  12. Reception is not an issue on any of the aerials, it is tuning for transmission only. Our old avionics technician at the flying club used to say all the time, "you can receive a signal on a wet piece of string" referring to the fact that you can receive just about anything in the air band using anything from a wet piece of string to a coathanger, reception is not the problem it is transmission. If the length is out for transmission you will have all sorts of problems. The very worst aerial he ever saw was the mobile one ground plane independent aerial. The one with a little rubber ducky on the bottom. He would hang up the phone if anyone called saying they had transmission problems and they were using that aerial.
  13. Looks great, well done and a real need for something that works !
  14. Who thought there would be lies in aviation !
  15. Some people rattle when shaken, they are full of nut's
  16. Nearly any plane ever made will be in the correct weight and balance range of 25% to 35% MAC, it's physics ? if you position the crew so they are at 40% MAC then you will fly very tail heavy and could possibly be uncontrollable.
  17. you just can't say do a proper weight and balance. You have to rely that the manufacturer is giving you the correct information to start with. If they are not giving you the correct information what ability do they have to make sure the design complies with such a basic and important calculation. I would say RUN
  18. Copied from another site. tail wheel Moderator "In February 2020, the Australian Civil Aviation Safety Authority released a safety notice advising of a number of fatal accidents globally involving spins and stalls of Bristell LSAs. The safety notice states "aircraft may not meet the LSA standards as it does not appear to have been adequately tested" and that "the manufacturer has been unable to provide satisfactory evidence that the design is compliant with the requirements of the ASTM standards applicable to light sport aircraft." The company contested the CASA notice and claims that spin testing was conducted, although the manufacturer prohibits the design from intentional spins. CASA indicated on 28 February 2020 that "further investigation and discussions with the manufacturer are ongoing and CASA will provide an update as new information becomes available." The Irish Air Accident Investigation Unit report in May 2022 on the crash of an NG 5 Speed Wing in June 2019, resulting in the death of the two occupants, and found that incorrect weight and balance information supplied by the manufacturer was a contributory factor to the crash and recommended that BRM Aero revise and enhance the operating guidelines for the aircraft. On 21 June 2021 CASA issued a notice indicating that the manufacturer had provided data on spin testing and had also amended its weight and balance information provided to builders and owners, including changing the datum from the wing leading edge to the engine firewall. CASA indicated that the amended weight and balance limits and new datum adequately addressed the safety concerns previously raised and "provided operators of the aircraft only operate the aircraft in compliance with the corrected AOI data, CASA considers that the potential for inadvertent operation of the aircraft at or outside the centre of gravity limits is substantially reduced."
  19. There is a record already for this aircraft manufacturer including falsifying certification documents, saying that the aircraft had been tested to certain standards etc. but none of this was actually qualified and the required testing was never done. If the testing had been completed then we could make sure the aircraft met certain standards but it seems like it doesn't. From memory and this is going back 4 or 5 years, the claimed centre of gravity position was something like 300 mm rear of where it needed to be. I don't remember the full story in total detail but it was all very dirty at the time.
  20. I agree with one track, a single aircraft incident, with or without fatalities is unlikely to be investigated by the ADSB. Had the same aircraft run into a house, a preschool or any public building then of course it would be thoroughly investigated (and the pilot, ((cowboy)) in said recreational aircraft) found guilty in record time.
  21. agreed with red, the pictures on the aircraft show 2 different types of exhaust system which are different from the one you are selling now. Brisbane is hard on motors but it does look like it is pretty old with extensive oxidisation and corrosion on the end of the crank and the flywheel. I'm not saying it isn't brand-new even though the photo showing running, but brand-new means as it came out of the factory. I really do hope it is the perfect engine for somebody's project but in one spot it says it uses 29 L per hour and another spot 9 L per hour. There are a lot of inconsistencies in your listing unfortunately
  22. Yes, it's shady white Couldnt resist.
  23. Is the plane epoxy or vinyl ester resins ? The specs are out there for max temps of all the epoxies, dont guess.
  24. Not sure ? 2CV ? Harley ? not many V's around
