And if there's a bomb? This is more related to the cabin crew, since the pumps will most often be in the cabin.
To find a bomb, you must first do a search called Sterile search method. Everything is needed. The cabin crew has specific instructions on how to do it. They usually start looking for galley and baths, from bottom to top, left to right. It will move to the passengers, since the cabin crew is still looking for seats, water containers, etc. If you have found a suspicious object. NO TOQUIS Ask the passengers to identify the document. If you do not know, the cabin crew must inform the flight crew. But the search does not end here, there may be more articles on the plane. Also, do not forget to check out the other crew members and their bags.
Therefore, the suspect object is on board and it is!
– Do not touch it.
– Inform the crew of the cab and the flight crew. Give a detailed description.
– If possible, send / show a digital photo to the flight crew.
– Remove the passengers from the object.
– Now is the great part of the flight crew. They must make the decision to keep the object in place or to move it to a place called "safe pump location / lowest risk pump site."
Commercial airplanes these days have something called "location of the bomb of security / place of bombs less risk". This is the place where if the bomb explodes, it would create the least damage compared to the rest of the plane. For this example, we will use the R2 door. This is the door on the back, on the right side (facing the flight / front panel).
Preparation of the location of the pump with less risk
– Disarm the slide
– Remove the security equipment. O2 Bottles, extinguishers and the rest. These could become a projectile in the event of an explosion.
– Empty 2 cars and place them on the floor, against the door.
– Paste the area with pillows, coats (ask the passengers, they will be happy to help avoid a detonation. Trust me. They will do it) and other soft materials. Do this at the height of the window.
– Place the object on top of it (As described below, how to move the object)
– Cover it with plastic to keep it dry.
– Cover with a layer of dampened material.
– Keep covering it with soft objects.
– Move the passengers forward. People stay out of the pump to sit next to one.
– Move below, behind the last row of passengers.
Move the object
This is the most complicated and risky thing to do for the cabin crew. For pilots or other crew members, make sure that those who move the object are not subject to tension and are able to do so. First, slide a card under the object in case it is equipped with an anti-lift device. Keep the pump in the same attitude as that found. Do not turn it around, do not throw it into anyone. One will carry the object, one will walk ahead and one will stay behind. To avoid any interference of passengers. Move it to the pump location with less risk, as described above.
Now it's up to the flight crew
Basically it declares an emergency, squawk 7700, control of call operations, descends as soon as possible to depressurize the plane (this prevents the detonation in case of a pressure pump) and find a site suitable for landing. The best would be a large airport, since they probably have the right facilities to deal with a bomb. But land as soon as possible is the priority.
