Alarm systems onboard modern marine vessels are designed to help the ship’s crew handle or avoid an emergency as quickly and efficiently as possible. Emergency alarms are both audible and visual, to ensure that a person can at least listen to an audible alarm when working in an area where a visual alarm is not possible, and vice versa. Alarms are also standardized based on international agreements, so that no matter what the vessel is or what flag it sails under, the alarms will be the same. This blog will break down some of the most common types of alarms, and what emergencies they react to.
Unmanned Vehicles are similar to cars yet getting a license for a car is far harder than obtaining a license for a drone. Because of their multiple forms and uses, the FAA has set out a strict set of guidelines that drone fliers have to comply with.
Of the six million parts that are used to make a Boeing 747-800, aircraft fasteners contribute to half of that number. Fasteners play a vital role in the overall construction and completion of aircraft. They are used to assemble and hold together various parts of an aircraft in primary structure areas, pressurized/non pressurized applications, and to transfer loads from one part to another. A wide variety of fasteners are used in the build of an aircraft such as nuts, bolts, screws, clamps, rivets, and many more.
The electronic components and wiring within an aircraft account for a considerable amount of space and overall weight. An average commercial airliner has a wire count of over 100,000, totaling up to 470 km of wires and a combined weight of 5,700 kg. Add an extra 30% of their weight that must also be incorporated due to the needed fixation structures, and you’ve got an excess weight problem begging for a solution. Wireless avionics intra-communications utilize radio communication systems that are installed on an aircraft, and they just might be the answer to the added load of electronic wiring components.
Hydraulic systems are common in modern aircraft. Most aircraft involve hydraulics at least once in their flight cycle. A single hydraulic system or multiple hydraulic systems may be used depending on the size, weight, and complexity of the vehicle involved. Components that implement hydraulics in their function include thrust reversers, landing gear retraction, spoilers, and nose wheel steering.
When it comes to aircraft lights, there’s a bit of ambiguity on all the rules and regulations. So, sometimes people don’t really pay any attention or care. Most pilots just do as they were taught. But that’s not good enough, so here’s a short explanation on the different lights.
The in-flight cabin crew is responsible for more than just providing refreshments and a pleasant experience, they are responsible for the safety of all passengers on board! In fact, passenger safety is the reason behind creating the position of “cabin crew”. The first flight attendant was hired in 1930 and was a certified nurse. Her sole role was to ensure the health and safety of all passengers aboard the flight. The airline had noticed that the presence of a flight attendant during flight resulted in passengers feeling more relaxed and secure. This positive feedback led the way for all commercial airlines to hire flight attendants for in-fight safety.
