Before a pilot starts flying, the pilot have to do a pre-flight where the pilot checks the body of the aircraft, the engine oil, fuel level, and the propeller to make sure the previous pilot who flew the aircraft did not have a bird strike (i.e. suicidal birds flying into the engine prop, lol).
There are checks before a pilot starts the aircraft, checks after he/she starts, a radio call to make before the pilot moves the aircraft, checks while moving on the ground, run checks to make sure the engine has enough power, and so much more. There are lots of other checklist a pilot needs to follow to make sure everything is alright.
An aircraft is pressurized meaning no air can go out and no air can come in. Above 7000ft to 8000ft, the air conditioning system must be working well, if not passengers will begin to pass out gradually. The reason is because, there is a certain amount of pressure required for humans to be able to breath and that’s the level of pressure we have on ground.
Oxygen percentage is the same on ground and up there but the difference is in the pressure, the pressure up there is like less than half of what is available on ground, that is why there is not enough pressure to push air inside the body or enough to keep the organs in place. So, the organs tend to expand causing pains to people and possibly deaths depending on how long each person stays after decompression (that is, a reduction in air pressure).
That is why if there is a loss in cabin pressure, the oxygen mask deploys. Now explosive decompression is when a plane flying at its usual 35,000ft and an accident happens, probably a missile blows open a plane (like we see in movies), or the bulkhead aft pressure gives way, or there is a sudden loss of air, or air rushing into the plane through a hole, passengers and cabin crew will lose consciousness very quickly as a result of hypoxia which is a deficiency in the amount of oxygen reaching the tissues.
But if the pilot can handle the situation, he/she has to descend to a breathable altitude, probably 7000ft to enable passengers and cabin crew breath properly, but it might be late then because death at 35,000ft occurs rapidly.
I can see some of the reasons why some people hate flying… Lol. May God save us all…
Diversion: Then how do people survive in Planet, Mars? Do they wear oxygen masks all the time? Hmmm, that’s punishment, I guess. I recall about 100 people were selected early last year out of the 202,586 applicants to go live in Mars forever…
From this picture I took at the cockpit above – There is the airspeed indicator to check and know the speed. The thing on the extreme left, that is the Artificial horizon, its coloured blue on top indicating the sky… If the triangle on it is in that section, then it means you are ascending. The lower part is brown in colour, indicating the Earth… If the triangle on that screen is there, it means you are descending.
On that same indicator panel just slightly to the right is where the present altitude shows too. The indicator that looks green with green lines is the PFD (Primary Flight Display), if I can remember correctly, Lol.
But from the picture, it is showing in the TCAS mode (Traffic Collision Avoidance System). It shows the probity of other aircrafts to the pilot and if that aircraft and any other one on a collision course have the TCAS 2 installed in them, they can by themselves resolve the best action to be taken when there is a risk of collision.
