  1. Certainly is in the US. All turns in the vicinity of the circuit are to be made in the circuit direction. Stops airplanes flying in opposite directions on the 'dead' side.
  2. The -800 does not have massive turned up tips either - a gentle curve up only. Closer look would have picked the shorter upper deck reminiscent of the -100 & -200 series. Cathay flies the -400 and the -800 freighter, but no passenger variants of any 747 any more. They retired their last - 400 passenger variant in 2016 and their last -300 in 1997.
  3. Needs an analogue solution. Take your watch off and close your eyes. Spin your watch around over your head clockwise (hence the need for an analogue watch so you can figure out 'clockwise') while spinning yourself anti-clockwise 3 rotations. Open your eyes and let the watch go. Note in which direction it went and turn so your left shoulder is facing that direction. The watch would have 'Gone West' so you are now facing North. Simples......

    Airbus A350-1000

    Correct for fact hunter. Approach speed is the minimum clean speed.
  5. About 1,700 feet in. Flared just past the 500 ft markers.
  6. QANTAS certainly had a procedure for a 3 engine ferry on the 747's, and there was a story that they used it to recover one from Darwin during the Cyclone Tracy evacuations. The inoperable engine was blanked off the same way as when carrying an extra engine underwing. Ferry with essential crew only.
  7. Works a treat for marine pilot boats that see some pretty heavy seas.
  8. https://www.seasucker.com.au/114-mm-seasucker-black-vacuum-mount/ Little vacuum pump so you can see when suction is being lost.
  9. It's quite common in countries in the rest of the World to allow landing clearances to be given if the controller believes that the runway will be clear when the subject airplane touches down, and not unusual to be issued a late landing clearance - even in the flare. A late go-around can be performed after touchdown provided reverse thrust has not been selected, and it is expected during a cat 3B approach. Not uncommon arriving into LA or New York to be issued a landing clearance with the runway occupied and yet another to land before you. In this case the controller believed that the departing airplane was probably > V1 when he issued the clearance. These 2 engine airplanes accelerate like the proverbial ...... and the take off airplane had rotated before the landing airplane touched down. Certainly looked close to the journalists.
  10. This is an unlicensed airdrome and the 'wind direction indicator' can be at whatever angle for whatever the wind strength the owner dictates.
  11. Somewhat true for old generation weather radars, the one's I have a little experience with post 1990 are pretty good, and suspect the 777 in this incident was better again. Comes down to interpretation though - how it is used and what avoidance action was attempted.
  12. Not the first time a Singapore airplane has stalled at high altitude. They use a much tighter margin to determine max altitude than others ...... The 6,000' descent would be down to the next available altitude.
  13. Air Canada ........... not US carrier.
  14. Looking at the E-Props GLOR-3-170-C8-T. Looked at going for a ground adjustable and still might - but I am not a 'fiddling' sort of person. Certainly will not be doing my own annual servicing etc. It's not about the maximum speed increase, it's about operating the engine in its maximum torque range with a lower throttle setting for range increase. I only have maybe 280 kgs to play with for useable load and 2 people my size and baggage etc eats considerably into fuel that can be carried. And yes, I know that the CS gear will weight, but the decrease in burn will more than compensate for that.
  15. Hi. Looking for opinions on fitting a 2 blade or 3 blade propeller to my Rotax 912is with a constant speed unit. Just in the ordering phase and wonder which I should go with. The airplane will be primarily used for cruising and won't be operating out of marginal strips. I know that the old wisdom was that 3 blades were better for takeoff and 2 blades for cruise as the 3 blade was 1) heavier and 2) had more drag, but a lot of that was based on either fixed pitch or ground adjustable propellers and is the wisdom still valid for operation with a CSU (mechanical knob to a hydraulic actuator) in the age of the new composite materials (light & stiff) the blades are constructed from.
  16. Greater than 80% load factor AND on routes around the 8 hours is their sweet spot. With lower passenger loads the 747-800 and 777's easily outdo it for fuel burn, and much greater then 8 hours the economics become less advantageous. Tis an exponential thing. For a European carrier such as Emirates that have a high density economy section and short leg lengths it works and works well, and it would be OK for Oz if we only flew to Asia....... It also works with high density and slot constraints, ie, the number of movements you are allowed at airports. But again, only with a very high passenger load as landing fees are based on airplane weight. With the same passenger load doing an LAX-SYD, the old 747-400 used some 30,000 kgs less fuel, and the Virgin 777's (when they were around) would do 30,000kgs less again than the 747. The A380 can't fly as far south (Latitude) between Aus and South Africa or South America than the 747's due ETOPS, so has to fly further and more fuel. Yes, they are a 4 engine airplane, but the outboard engines provide thrust only, same as the A340's. The right airplane for Oz was the 747-800 but Boeing got it going too late to get enough orders in to make it viable.
  17. Once again Australian CEO's are cleverer than the rest of the World. A380 was a shockingly bad choice to begin with and only happened because Airbus gave away free A330's to go with the purchase deal.
  18. I believe that RAAus is working on having the BFR done in an RAAus aircraft be valid for your CASA licence as well as your RAAus certificate sometime in the future. Possibly tied in with RAAus instructor ratings be accepted as CASA endorsements. Don't hold your breath .........
  19. sometimes they find a target to home in on .... taken from my office window a few years back
  20. Don't know where you are getting your LAME from, I have been quoted $2.5 to $3 thousand pa for an LSA with 912is with constant speed prop.
  21. I think they have a choice .....
  22. December 24, 2015 Arizona Senate President Andy Biggs on Tuesday appointed Sen. Sylvia Allen as the new chairwoman of the state's Senate Education Committee. And what better role for Allen, who has been building her credentials for years with bizarre statements on chemtrails and a fervent belief in creationism, than leader of an education-focused body? They are all just nuts over there ..........
  23. Sorry - you think that EV's (cars/scooters/motorcycles/airplanes) use lead acid batteries? Lifpo battery for 2 hours lighter than your 98 octane (11.2 kgs by the way) and an electric motor lighter than your 40hp conventional engine. Your argument doesn't carry weight .....
  24. Like this a lot. All it needs is an electric drive and you can sit in it as well ...........or add a folding electric scooter to your away kit for an additional 30kgs and you can tow it. Handy to get into town or that camping spot on the beach.
