- Comment on Height-adjustable bar stools slowly sink when I sit on them - gas lift/cylinder problem? 2 days ago:
It’s a little weird it’s all of them not just one or two, so maybe someone has a better idea, but the symptoms sound like it’s a gas cylinder problem. Afaik they sometimes get a little dust and dirt in the seals and don’t seal off proper any more. But since it’s all of them the gas cylinders might just be cheap or not suited for the task.
I don’t know if you can repair them, I’d be a little careful, since those are built to handle some weight they can be under a fair amount of pressure. So disassembling one of the cylinders might be dangerous.
There are several different sizes of those cylinders, so you’d need to measure one of them before ordering. I’d just look up what measurements are listed for those cylinders online and then disassemble one stool and take the same measurements. Other than that they should be replaceable fairly easy.
That’s the knowledge I accuired online when my beloved office chair started to develop the same issue, but since it still functions most of the time I never got around to actually disassemble it, so take everything I said with a grain of salt and maybe get a second opinion. Good luck!
- Comment on The investigation of the Tenerife airport disaster didn't need to run past 3 pages 1 month ago:
Worst aviation disaster in history. Basically the pilot initiated the take off during poor visibility and without proper take off clearance despite his cabin crew repeatedly voicing doubts about the runway being clear. The plane taking off crashed into another plane that hasn’t cleared the runway yet, killing 583 people.
This accident lead to several changes in aviation procedures, including Crew resource management. The captain overruled legitimate concerns of his crew by pulling rank - now the procedures call for every cabin crew member having equal voice in concern to flight procedures. Also :
The word “takeoff” is now spoken only when the actual takeoff clearance is given, or when cancelling that same clearance (i.e., “cleared for takeoff” or “cancel takeoff clearance"). Until that point, aircrew and controllers should use the word “departure” in its place (e.g., “ready for departure").
That was also a point of confusion due to garbled radio calls.
