  1. The seat covers give a clue. Very Airbusish. So French, 1960's feel with updated avionics which leads to the Dassault Mercure 100...?
  2. Better option than hitting the airframe with planet earth at great speed...
  3. I am privileged to have attended one of her talks to a sporting club. Marija is an amazing lady who has overcome many challenges to get where she is today. Highly intelligent, a highly qualified engineer and test pilot. A wonderful immigrant story. Such qualifications don't come easily. Her troops admire and greatly respect her as a Commanding Officer of a P3 Squadron (at the time of writing). There are many people who have met her who would be very disappointed if this discussion were to head down the wrong path.
  4. The fact one would consider exposing one's self to such scrutiny reflects poorly on us all. No wonder the insurance premiums are so high. The responsible majority are subsidising the lack of measured forethought of others.
  5. You may find that the insurance company will beg to differ on intentionally operating outside of the specifications.
  6. Unfortunately not the first time the Froggies have ruined a new toy... https://aviation-safety.net/database/record.php?id=20071115-0
  7. I've been to FL430 many times and M1.5 on one occasion. We share many diverse experiences, all different but none better than another!
  8. If you look at 25:02, you will get a brief glimpse of the PFD. 104KIAS/70,000' and M0.707. The air is indeed thin! The best of TOP GEAR.
  9. The speed of sound is purely a function of air temperature. So if you are on the ground in Siberia at minus 60 degrees celsius the speed is the same as minus 60 degrees at say 40,000'. From memory the formula is: 38pointsomething x the square root of the absolute temperature. Absolute temp being zero at ~minus 273°. Your Mno is the ratio of your true airspeed/local Mno. At sea level and ISA (+15°C) at 250kts indicated your TAS is 250kts and the Mno is 250/661~0.38M. As you climb out at 250IAS your TAS will progressively increase (eg+16%@10,000') as the air DENSITY decreases. Assuming a standard atmosphere the local speed of sound will decrease with temperature until it is ~573kts@36,090'-the tropopause where the standard temp is -56.5°C. Typically in the cruise the numbers you will see might be: 36,000'/245KIAS/M0.78/460KTAS There is a lot more to the story but I won't bore you with that.
  10. I think ATC gave them a new route to that planned (perhaps MIL airspace) thus the reason for the full readback. In AUS (including WA...! ) If the flight were as planned then only the initial waypoint that joins the airway is needed eg ATC, "N6BX cleared to Sydney via SEDAN, flight planned route. SEDAN2 departure, climb via the SID 5,000, Squawk 3414, departure freq 118.2 You read it all back and give your parking position at the end. If you are fancy enough to get a PDC the only readback is SID , Squawk code and parking position.
  11. Yes, you are correct but that is not what was said. An erroneous RA signal earlier on the approach can command the auto thrust to idle thinking it is in the flare.
  12. As mentioned the 5G can interfere with radio altimeters on aircraft. Usually there are two fitted. So what you might say but the RADALT signal is intergrated into many aircraft systems. For example it changes the sensitivity to the ILS signal as you get closer to the ground. If both radalts are unserviceable the approach must be flown manually (Airbus) as the autopilot will not receive correct commands as altitude reduces. During autoland operations in low visibility it commands the engine thrust to idle during the flare. If interference occurred from a 5G signal the engines could go to idle at say 2,000' thinking it were in the flare. There are dozens of other potential problems but the above gives a taste of the issues! http://www.alpa.org/resources/aircraft-operations-radar-altimeter-interference-5G#:~:text=Radar altimeter interference from 5G signals can take the form,1951 in Amsterdam in 2009.
  13. How is your aircraft progressing mate? Looks good!
  14. Yes, there are logistical issues that are NOT insurmountable. What ever the issues it would be a lot smarter than the current situation of utilising a dodgy hotel in a capital city.
  15. Are you sure they are olive trees. Some where near Griffith 🙂
  16. In the early 80's there was a mosquito (ultralight) at Forbes aerodrome in the eastern shed. Anyone know it's history?
  17. Did Trevor sponsor you with free beers at his pub?
