    Very sad

    Try google earth, flight sim, anything that can help you. If using 29 in ycab, on downwind confirm your heading is 110, look for parallel runway and be patient.

    Overfying and maneuvering (turning, descending, climbing, positioning) on a "dead side" is normal procedure, not part of a circuit/pattern procedure. An airwork may be conducted there. Be prepared to expect anything when vfr in g class, however once in the circuit - everyone follows the same procedure. I was hoping the disclaimer wasn't needed, but I was wrong. *Disclaimer: The drawing is not to scale *Warning: choking hazard, might send shiver down the spine

    Tailslides / Whip stalls are prohibited maneuvers not only in Cessnas, but in some aerobatic aircrafts. Aircrafts are designed to fly forward where aileron/elevator/rudder hinges/mounts are relatively protected from the airflow. Flying backward with controls deflected would exceed structure limitations of the controls and can cause control surfaces breakup. That's why in a Tailslide it is better to keep controls firmly centralised and let the gravity (and airflow) do the job. Agressive whip stalls can also rip the engine mounts. ps: CASA part 91, aerobatic manoeuvres, for an aircraft, means manoeuvres of the aircraft that involve: (a) bank angles that are greater than 60°; or (b) pitch angles that are greater than 45°, or are otherwise abnormal to the aircraft type; or (c) abrupt changes of speed, direction, angle of bank or angle of pitch. If your friend is not aerobatic rated he would be breaking laws

    To my knowledge, there are no rules about maneuvering on a dead side. However, if you overfly right-hand ccts and descent turning to the right, you will have more space (longer downwind), as opposed to if you are turning to the left.

    Last time no fly-ins were allowed into Avalon East, and never into Avalon. Instead, flying visitors were diverted to Lethbridge, some 50kms via road, then buses organised to Avalon and back. To my understanding, Avalon East property/aerodrome was sold, and new owner is using land for agriculture, or something similar. Pity that we can't organise something similar to Oshkosh.

    I believe they still teach how to use sextant for navigation at some yacht or marine clubs, also, have a look at this video:

    Nope, MAWT Mawson Time Zone is UTC+5 https://www.antarctica.gov.au/antarctic-operations/stations/mawson/ And here is the list of all research stations and corresponding time zones in Antarctica. https://www.timeanddate.com/time/zone/antarctica As we speak, millions of people in India, Philippines, and other countries are living and working in different time zones (US,EU,Aus). Time is relative.

    Let me use plain language. So let's say you live in Melbourne and it is noon, your watch is showing noon and the Sun is (approximately) at the Zenith above. Now, lets say at the same moment you are at the South pole flag and surely if you walk towards the Sun, this is where Melbourne is. Contrary-wise, at the same time it is a midnight in South America, so Sun definitely won't be there. At the same time it is mid-morning in Perth (-2hrs) and mid-afternoon in New Zealand (+2hrs). Since 360deg / 24hrs = 15deg, to go to Perth you will need to turn 30deg to the left, or if you want to go to New Zealand you will have to turn 30deg right. So watch is the key. Hope that make more sense.

    i thought we are discussing the concepts, not real-life scenario. however if you somehow got teleported to the pole flag during the polar day, walk in one direction until notice the difference (it will be a long walk), record sun position at noon(sunrise/sunset) then use triangulation to turn into correct direction. if you don't see the sun at watch's noon, then return back to the pole flag and walk in opposite direction. you can use watch and star constellations for navigation at nights, but you will have to know its position seen from your home at the same day.
  12. Bosi72
    Use your watch. If the Sun is above(peak) at noon, then you're in good direction.

    I don't think anyone lives on the water permanently as the Arctic is not a landmass, it's a frozen body of water which gets partly melted seasonally, but let's not get into that.. I guess whatever ships/subs/research stations/etc are there will run on their own home country time. However what puzzles me more, are the timezones of the roadhouses along the Nullarbor..

    The radio calls should be taught and practiced in schools as an airmanship that radio calls can be made at any leg/position when required. Clearly an aircraft doing ccts and making base calls only every 6-7mins, then hearing another aircraft at 10 miles, and not announcing his/her presence, is an example of poor airmanship. When I'm inbound and feel that something's not right, in addition to 10miles call, I announce 5 miles, 3 miles calls. ------------------------------- – You must make a broadcast when any of the following situations exist the pilot in command considers it necessary to broadcast to avoid the risk of a collision with another aircraft (91 MOS 21.04(1)) -------------------------------

    Not likely. The recent Singapore 777 turbulence accident experienced severe turbulence from -1.5G to +1.5G. +3.9G is likely the 4th quarter of the loop (or reverse half cuban, or some other loop-like manouever).
  16. Bosi72
    It depends how pilot wants to punish himself/herself. That will do a nice Loop.

    Someone was doing aeros 🙂

    It will if the android/ios device have the internet connection whilst in the air.

    7% is for short dry grass

    My apologies I've just checked your Jabiru model is 230 whilst the data I used was from 160 model.
  21. Bosi72
    Well done on making a decision about aborting the takeoff! However, I would strongly suggest consulting the POH and performance data for any aircraft before the flight. I've never been in Jabiru, but the performance chart from POH says it wiill need 464m for a takeoff at sea level at 20C at MTOW. The POH also says add 7% for a short grass, and even more if wet (unchartered territory). Planning before the flight is the key.

    AIP ENR 1.1-65 para 9.12.3 "joining overhead" AIP ENR 1.1-57 para 9.1.14 "radio calls" ERSA for specific aerodrome procedure https://www.airservicesaustralia.com/aip/aip.asp?pg=20&vdate=13JUN2024&ver=1

    AV30 is not yet approved for IFR, regardless it is good to see competition on the market. I prefer round displays, rather than squared.. https://uavionix.com/faq-items/is-av-30-approved-for-primary-ifr-navigation/

    Out of curiosity, is there are website with the list of all Raa registered aircrafts ? Eg. an equivalent of Casa's vh- register https://www.casa.gov.au/search-centre/aircraft-register Thanks

    Last weekend at the 50th Anniversary of Antiques Aeroplanes Association in Corowa, NSW. ~150 aircrafts attended the Fly-in. Great event, lots of activities, fun.. Camping under the wing - Priceless !
