Angle of attack (AOA) sensors are some of the most important safety parts of the aircraft. They must be protected very well. That’s why, today we’re going to present you our cover for angel of attack sensors of the aircraft.

What is angle of attack sensor?

AOA indicators provide a visual representation of how much lift is being generated by your wings for a given airspeed. This is incredibly useful because speed alone is not a reliable parameter to avoid a stall. That’s because airplanes can stall at any speed, as long as they exceed their critical angle-of-attack.

AOA could be determined by signals provided via these sensors. They measure the current AOA of the aircraft in comparison to the aircraft’s critical AOA.

How many aircraft sensors Airbus has?

Airbus aircraft require three AOA sensors because they’re considered safety critical. So you need at least three of our AOA covers to protect the sensors.

No matter how often you fly with an aircraft and how many different destinations you visit, each time before the plane takes off you here one thing. Could you guess what is it?

Of course, the pre flight demonstration of the cabin crew. Maybe some of you know it pretty well.

It usually starts with a quick presentation of the airline and its safety rules.

After that, you will be asked to stow your baggage away safely, either in the overhead locker or under the seat in front of you (non-exit rows only). The tray table should be stowed away, and the seat back put upright and leg rests put away.

Before each flight the cabin crew takes away the safety card from its demo-kit bag and puts it in the pocket of the seatback or in the pocket of the bulk head.

Each cabin crew has its demo-kit bag. Usually it contains demonstration life jackets, oxygen masks, seatbelts, passenger safety information cards, fire proof gloves, fire proof bags etc.

In WAS you could find such demo-kit bag which is made by high-quality materials. Also, each item in the demo-kit bag is stored carefully in different departments. Each airline has specific needs for what is put in the demo-kit bag That’s why, we in WAS can prepare different demo-kit bag depending on your requirements.

The fire proof bag is one of the most important safety elements for the cabin crew. You could use it for many different things such as laptops, Lithium-ion batteries, electronic devices, etc. 

The role of the fire proof bag is to protect your devices from damage during the flight. We should mention that before we put the fire proof bag into usage, we taste it in different situations. We through it, we drop it and so on, until we don’t prove ourselves that it’s perfect.

The fire proof bag could be order in different sizes but according to the standards it could be two types: Tote-Style or Envelope-Style. The Tote-Style bag is available in one size (24″ x 13″ x 5″) and features a flat bottom and 3-dimensional design that allows the bag to stand upright, two nylon carrying straps, and a zipper closure. The Envelope-Style bag is available in 2 sizes (16″ x 18″ or 18″ x 24″) and features a flat design that takes up minimal space, a zipper closure, and a Velcro flap.

We at World Aviation Solutions (WAS) offer fire proof bags with high quality and for each purpose. You could view this item here. If you choose our fire proof bag, we will make you an offer depending on your requirements.

The remove before flight pins or are a distinctive and very important element of the aircraft pushback procedure.

It’s usually red because it should be highly visible. The main purpose of the remove before flight pin is to serve as a reminder pilots, maintenance crew and ground staff that certain items or devices should be removed before the aircraft takes off. The role of this items is to protect the aircraft while it’s on the ground.

The bigger part of the remove before flight pin of World Aviation Solutions (WAS) is in red because it should be easily readable.

There is different remove before flight pins that assure the safety performance of aircraft pushback. Its role is also to ensure smoothly pre-flight checks. It’s usually coated in PVC to assure enough strength. It features a brass grommet for quick and easy attachment to a bypass pin or other accessory.

These flags can add to your pre-flight safety when secured to nose & landing gear steering bypass pins, wheel chocks, and gear covers (such as pitot tube covers, intake or engine covers, cowl plugs, and wheel covers).

The remove before flight pin of WAS has found a home outside the aircraft industry – they can be used as a reminder to remove a wheel lock from a motorcycle, to remind drivers to disconnect an engine block heater from their car or truck, as a gun chamber flag, or for any object that should not be forgotten. If the remove before flight pin is not removed, it disables the nose gear steering.

The importance of disabling the nose wheel steering could be described in two ways. First, it allows the hydraulic fluid to bypass the main nose wheel control valve, allowing the tow truck operator to steer the nose wheel with no restrictions. The other reason is directly related to the safety of the operation. This is because most of the times, during the push back, the aircraft engines are started. This powers up the hydraulic systems of the aircraft. When hydraulics are powered, the nose wheel steering is also supplied with pressure. And as the steering is designed to center the nose gear when there is no input from the pilot, and if at that point of time, the tug operator is making a turn, the nose wheel steering can over power the tow bar and break it. This can damage the nose landing gear and can even throw the tow truck out of control.

The consequences of leaving the pin in a heavy aircraft is only that the nose wheel steering will be disabled. There is a separate pin which locks the gear to prevent it from retracting. We only use the bypass pin for push back and that is what the engineers show us after completing the push back procedure. In some smaller aircraft, there is only one nose wheel pin and that does both the job of locking the gear and disabling the steering. Once the push back is over and the parking brake set the captain calls the engineer on the intercom and says, ‘Two good starts, clear to disconnect. Hand signals from Left or Right.’ If the engineer opts to show the pin from the left side, the captain gives a thumbs up and a wave and if it from the right, the first officer gives a thumbs and waves the engineer off.

Also, at the end of the pushback procedure, the ground personnel should lift his/her arm and show the remove before flight pin to the pilots. This guarantees that the pushback procedure is completed safely.

To guarantee aircraft safety, you should change the remove before flight pins in some periods. You could find remove before flight pins produced with a world standard checking our web site here.

The aviation safety on the ground is as much important as during a flight. Many people don’t know but one of the tools that secures the safety of a parked plane is the wheel chock.

The wheel chock is a small tool used to prevent the aircraft from moving on the ground. Some airports have huge incline and there the wheel chocks plane crucial role for avoiding accidents.

According to the airport safety rules, wheel chocks are being put on any vehicle that operates on the apron. Such are baggage belts, forklifts, push back trucks, etc.

Why the wheel chocks are used in the aviation?

Despite any airplane has a breaking mechanism, there is always a risk of disaster. Wheel chocks provide vital physical support, keeping larger vehicles in place.

What types of wheel chocks exit?

Usually, wheel chocks are made by rubber, aluminum or plastic.

• Aluminum wheel chocks very often have teeth located at the bottom. Its role is to provide friction and stability when they come in contact with the wheel.
• On the other hand, plastic and rubber wheel chocks are made by non-slip material to prevent from moving.

The wheel chocks also defer by their shape. Some of them are curved which helps to fit snugly around the wheel. Others have a pyramid shape. This helps the wheel to be fit tightly between two chocks.

In our next article you will find the different types of standards for producing wheel chocks and which are determined regarding the safety measures.  

At WAS, we could deliver any wheel chocks for as for the commercial and military aviation. The only thing you should do is to call us and describe your needs for wheel chocks, so we can deliver the best product.
