    Anyone that has been on a long haul flight, will tell you how incredibly boring they are ! So maybe pilots should do the occasional nose dive, barrel roll or a loop de loop to liven the flights up and excite the passengers 👍🏻.

    You know, I recall flight attendants always saying wear your seatbelts at all times when you’re seated. If you sleep on a long haul flight like SQ321, they ask you to put the belt over your blanket so they don’t have to disturb you to check. I know you’re still at risk when standing and moving around, but it minimises your exposure time. And crews can normally detect it a few minutes in advance and turn on the seatbelt sign. For those who wonder why the pilots can’t just change direction at will, aircraft are following a specific track, and unless they have an emergency to deal with, they can’t just change heading without checking there isn’t nearby traffic they’d endanger or even collide with.

      Exactly. For pilots it’s 100% of the that at the lap straps are worn . For takeoff & landing the full 5 point harness. Imagine if pilots don’t do that and both get knocked unconscious in the first 2 seconds- it would be curtains for everyone onboard!😮

    It is simple.Wind travels in different directions at different levels.Where these levels meet is called "wind shear" , the greater the difference in speed causes turbulence , so since hot air rises and cold air sinks the nearer the tropics the greater the chance of severe turbulence.

      All over CZcams. Look up 777 design upper load limit testing. You’d be sure to find one. Design upper load limit is the classification of stressing a plane to 1.5x what can reasonably be suspect to be found in actual flight in terms of stress.

    People are always going to ask questions when something like this happens, particularly when it's in the same area a similar aircraft completely disappeared a few years ago, because there are about 8000 planes in the sky at any second on any day and this isn't happening more frequently and because they regained control before it happened again.

    You wouldn't disconnect the autopilot at 36,000 ft - the aircraft is in such a small envelope that many authorities forbid hand flying above 29,000ft

    • @TheChiefEng
      @TheChiefEng Před měsícem +9

      First of all, if the turbulence is severe enough and the movement of the airplane great enough, the autopilot will disengage automatically, but with an extreme vertical movement of the airplane, the pilots will definitely take manual control for the simple reason that leaving the autopilot engaged could make things worse because the autopilot will try to return the airplane to the set altitude again which would not necessarily be the desired action you want if the airplane has just dropped several hundred feet.
      Every airline has their own procedures for this.

      The first thing you do in severe turbulence is disconnect the auto pilot, set a certain thrust called turbulence penetration thrust and aim to minimise altitude deviations.

    • @alexc4300
      @alexc4300 Před měsícem

      Higher flight level means less air resistance = better fuel economy. And usually less turbulence. But it can happen at any flight level current civilian aircraft can reach. Also note that it’s incredibly rare to have a serious incident such as this, which is why it’s newsworthy. How many car crashes took place during the 13-odd hours of that flight? With far higher numbers fatalities in many cases. Sense of proportion matters, people.
