5 Things that Airplanes are Required to Have on Board that Passengers Cannot See
An airplane is a complicated piece of machinery that serves as a backbone for worldwide travel. As the passengers consider mainly their comfort onboard and in-flight experience, there are several items present inside an aircraft that are out of sight and play a crucial role in flying. These are legally needed and allow for the safety, efficiency, and functionality of an airplane in the skies. They may not form part of the passenger experience, but they are crucial to making air travel possible and secure. The following are five crucial things that are on the planes that passengers generally don't see.
1. Aircraft Fire Extinguishers: Silent Guardian
Of the many elements concerning flying, the fire suppression mechanisms remain amongst the most critical, even though the majority of suppression systems aboard the aircraft are kept well out of sight. Aircraft fire extinguishers are installed throughout the aircraft cabin and cargo hold and inside the cockpit. Because of the peculiar, confined spaces encountered in an airplane and because the development of an airplane fire progresses in a rather highly rapid manner, different types of extinguishing agents need to be carried. Fire extinguishers within aircraft have, therefore, to be built and approved with some specific norms or standards against such fires in the galley, compartments in avionics, or even the engine compartment. Passengers may never view these vital tools, but knowing they are there in the unlikely event of a fire emergency is comforting.
2. Cockpit and Cabin Pressure Control Systems
A stable onboard environment is as important to passengers as it is to the aircraft. The cockpit and cabin pressure control systems regulate airflow and maintain a comfortable and safe flight are located behind walls and panels. These systems are struggling ceaselessly to work out a constant in-cabin pressure despite the airplane's ascension at altitudes well above the external value of air pressure. In other words, had it not been for these mechanisms, passengers could have felt discomfort and would present a hazard to serious risks to flight crews on board. Their control systems ensure fine-tuned adjustments to the cabin pressure concerning altitude, complementing the delivery of oxygen according to altitude pressures, especially in cabin depressurization incidents.
3. Flight Data Recorders and Black Boxes
Flight data recorders, also known as black boxes, are another critical component of every aircraft. These devices record data related to the aircraft's operation, including speed, altitude, engine performance, and more. The black box is invaluable in the event of an incident, as it provides detailed information that helps investigators determine what happened during a flight. Although the black box is an essential aviation safety gadget, it is kept in a safe area of the plane, which passengers do not have access to. The data obtained after the incident aids in developing safety measures and improves aviation technology for the future.
4. Emergency Oxygen Systems
Whenever passengers get on board a flying machine, they always expect an uneventful trip. However, in case of a depressurization accident, an emergency oxygen system is ready for deployment. Oxygen masks are hidden in compartments above every seat and automatically drop down if needed. The system is designed to deploy oxygen from tanks that are kept in safe places on the aircraft. Passengers will not be aware of these systems until the masks drop down, but they are essential in maintaining safety during such instances. In addition, there are also separate oxygen supplies for the pilots and crew for use in high-altitude emergencies.
5. Hidden Maintenance Equipment
Airplanes are constantly being serviced to maintain airworthiness, but much of the equipment and tools used to perform the maintenance checks are not seen. Among these tools are highly specialized pieces for the inspection of the aircraft's engines, wings, and fuselage. From diagnostic machines to cleaning supplies, the equipment that keeps the aircraft intact is carefully stowed in compartments, and service areas passengers never see. It is routine maintenance that keeps an aircraft flying safely, and the mechanical parts working properly, and it forestalls possible issues before they happen.
Conclusion
While passengers concern themselves with comfort, there are a lot of important items that go into keeping an airplane safe and functional. Everything from fire extinguishers to the hidden tools for maintenance helps keep things running right while up in the air. Fire extinguishers in aircraft, pressure control systems of an advanced level, and black boxes add to the overall security of the flight. Knowing how many of these items exist and their importance would give passengers a broader appreciation for how complex and safe modern flying is, even though one might not experience this firsthand while actually flying.
