How Aircraft Monitoring Systems Works?

Aircraft Monitoring SystemsAircrafts are held up to extremely high standards simply because of what it was made to do. It is responsible for so much and has the immense capacity to carry what it needs to carry across the country and overseas etc. Aircraft engines are the most expensive part of an aircraft and can cost as much as millions of dollars. Therefore it is critical to continuously monitor via many different types of sensors it in order to avoid extremely expensive repairs.

Monitoring systems collects data and transmits it for review and if action is necessary it will be carried out. Repairs take time due to the engine being taken for long flights. This would require a replacement engine being brought in which is also an expensive process.

Aircraft Fuel Gauge: Best Way to Monitor Engine Health and Air/Fuel Mixture

Aircraft Fuel GaugeIt is obvious how you or your close friend may have been frustrated when you were driving and you ran out of gas while you were driving. Of course, there are various inconveniences and delays especially when you were a far off from the nearest gas station. You must have learned a good lesson of always checking fuel before starting your journey.

It becomes a real tragedy and disaster when an aircraft runs out of fuel while in flight, especially in small aircraft. Due to the advancement in technology, if the plane happens to run low on gas, they can be refueled while still in flight. However, you need a very accurate device to gauge fuel in an aircraft having in mind that lives can be lost in case it is empty. Let’s understand how this aircraft fuel gauge works.

How Does Aircraft Fuel Gauge really Works?

For smaller aircraft, they usually use less complicated float level gauge which uses magnetic couplings and other potentiometers which show fuel levels to the pilot. In larger planes, capacitors are usually mounted in airplane’s fuel tank. The capacitors show the information into the computers which calculate the levels of fuel that’s consequently shown on the fuel gauge.

In cases where the pilot is supposed to know every level of fuel in the tank, multi-level sensors are installed to transmit the information to the pilot. The fuel system also indicates the pressure, any air/fuel mixture, and temperature of the engine which is transmitted to their respective sensors. The sensors show the injection rate of the fuel and also show any harmful condensation in the engine.

The Aircraft fuel gauge is very important to the pilot to determine the health of the engine. In case there is any malfunctioning of the engine, the pilot is able to detect it on the fuel gauge. Basically, the aircraft fuel gauge is connected to various Aircraft Level Sensors that are installed in the engines and fuel tanks.

A. Common Challenges Associated with Fuel Levels in an Aircraft

One of the main practical challenges that may arise as a result of inaccurate measurement of fuel levels is the tragedy that will result in loss of lives. Most of the times, aircraft fuel gauge is affected by the height in altitudes. Altitudes mostly affect the density, volumes, and transmission of fuel levels to the fuel gauge which consequently affects capacitors.

Turbulence is also a major challenge, especially in larger aircraft. It disables the capacitors in their fuel tank and hence they cannot transmit any information to the gauge.

In conclusion, in cases of any challenge in the Fuel Gauges pilots are trained to estimate the levels of fuel depending on the plane’s consumption rate and the existing fuel in the engine. However, they may not know the health of the engine in case there is any malfunction, fuel leaks, excess consumption, air/fuel mixture and any fuel blockage. Therefore, you need a functional fuel gauge.

What are the Features of EGT Probe & How It Works?

EGT ProbeAccording to research and study done about sensors or probes, there has been a conclusion that an Engine monitor is just as good as its own probe. This is the reason why various different electronic companies are daily adapting to trends and taking probe manufacturing very serious. An Exhaust Gas Temperature (EGT) probe is a temperature detector that is mounted on exhaust or turbine that relies on thermocouples and therefore it does not require electricity for it to work.

A thermocouple is a temperature sensor that is made up of 2 different types of wires that are joined at some point that measures the temperature temperatures in Celsius or Fahrenheit.

Outstanding Features of an EGT Probe

The following are some of the characteristics of a genuine Exhaust Gas Temperature:

• It has a voltage display – an EGT which is single channeled can measure battery voltages of at most 30V which is designed with a programmable alarm that senses high or low voltages, failure in drive belts or faulty batteries.
• Has a settable high alarm
• Time display meter – this determines the actual time of ignition
• It has a service-interval reminder which is inbuilt
• It contains both an audible and a LED visual alarm – the audible one can be turned on or off when viewing something while the visual one grows red at an occurrence of an alarm condition
• External alarm output that’s for remote indicators
• Have LCD that have graphics that are sunlight readable
• It has a high voltage protection for harsh environments vehicles and also has voltage reversal

Basic Layout of an EGT

When you see an EGT you will see the following:

• An Audible alarm
• LED alarm
• A harness – it connects power, thermocouple and external alarm
• Down button – adjust the contrast
• Menu button – enables you to access the menu system
• Up button – increases the contrast to maximum
• An LCD that displays the graphics

How Does an EGT Really Work?

The thermocouple is the heart of EGT. When the temperature increases at its junction, the metals that meet expand producing electrical pulses. Basically, the level of voltage being generated by these pulses is dependent on the type of metal of thermocouple and the amount of heat.

The sensor is usually connected to a Fuel Gauges that registers the level of temperature that is generated during the throttle or normal functioning of the engine. If there is damage the red Led light will glow. Just know the lower the ETG the more efficient is your engine.

In conclusion, an EGT Probe is one of the most important sensors that can warn you as a driver in situations that can damage your engine and will actually guide you on the level of fuel to use. However, it is advisable that you don’t use excess EGT which can destroy your engine.

How RPM Sensor Is Important In Aircraft System?

RPM SensorAn aircraft RPM censor is one of the most important instruments inside of an aircraft. This specific instrument measures the RPM of the Bendix in the Magneto, or the Bendix inside the Slick Magneto. More recently, they have been used in the Dual Magneto, but this is not a popular application.

The Bendix Magneto can easily be repaired if something goes wrong with it. Typically, you can tell there is something wrong with the Magento by the report sent back from the sensor. Since aircraft is not a popular focus of manufacturers, the most popular options are made by J.P. Instruments.

What Does the Magneto Run Off of?

The Magneto does not run off of the aircraft’s battery. Instead, the power to the magneto comes from the spark plugs, which work like a miniature generator. The Bendix Magneto acts as a small generator would, but inside of the aircraft. It also serves as a transformer, a breaker switch, and a distributor guide, which provides a high amount of power back to the spark plugs.

The RPMs are relayed into the cockpit and read by a sensor. The pilot is able to gauge the function of the components it is attached to, to ensure that the aircraft is operating normally.

Why Do You Need an RPM Sensor?

The RPM sensor inside of the aircraft is essential to the safety of flying your plane. Any sudden drop in RPMs on the sensor Fuel Gauges can alert the pilot of a significant problem or deficiency with the spark plugs of the craft.

Generally, the magneto wears equivalent to the rate of the point faces. The system was designed this way so that the pilot can monitor the wear of the components and ensures that all aspects of the plane are functioning on the same timing structure. If there is a fluctuation in the RPM sensor, this could mean that there is significant wear to the components that could result in equipment failure.

The pilot can also tell if the cam follower has adequate lubrication by monitoring the RPM sensor. They will have warning before the aircraft engine develops delayed timing, or if the fuel is not being burned properly.

When to Replace the RPM Sensor

If you notice any deviation in the RPM reading, you should first have all of the components connected to it checked. Some of them may need to be replaced. If you have replaced all of the parts that are associated with the RPM Sensor, and it is still providing a fluctuating reading, you should probably replace the RPM Sensor.

Replacing the sensor is a lot easier than you may think. All you have to do is remove the vent plug from the magneto plug. Insert the right aircraft flight instruments (which will vary depending on your specific aircraft). Feed the wiring bundle toward the firewall, but do not detach it. Make sure you have enough slack in the wiring bundle and plug the connector according to the package instructions.

How Does Aircraft Level Sensors Work In An Aircraft?

Aircraft Level SensorsWhen you are traveling by plane all you worry about is the time of your flight and your baggage. But, if you are driving a plane then you need to worry about many other things besides time and baggage.

Being a professional in aircraft area, you should know more about aircraft level sensors, how do they work and where you can find quality and safe aircraft gauges. When you are on the ground and driving a vehicle, you have magnetic level indicators that show you the situation with fuel and all other mechanical components of the car. On the aircraft there are two ways of knowing how much fuel you have in the tank:

* First, is knowing that the aircraft is the same magnetic level indicators like a vehicle, only they have a float which is magnetic and lifts your ‘dipstick’ up and down.
* Second, is analyzing and following the fuel gauging system. For example, you have some (about 30 on an A320) low voltage capacitors. This is where the fuel can flow between them. So, when you have fuel on a different level, you will also have dissimilar capacitances. In this way, you as a professional in aircraft field will know how much fuel the aircraft has and where your level is at.
* Density and permittivity readers. Besides, the two previous mentioned ways to know how aircraft levels sensors work in an aircraft and how to know the level of the fuel, there is one more thing that you should be aware of. There are a density and permittivity readers in the tank to then calculate the fuel quantity. It is in kg or lbs, which depends on the model of the aircraft. Then you have level sensors. What you should know about aircraft level sensors is that they have two states they know. Either is “wet” or “dry” which will trigger certain valves and warnings.

Knowing how does aircraft level sensors work in an aircraft, it is time to go on a next category which is searching for the right aircraft gauges and sensors. Small aircraft are having simple float level gauges. They give information on fuel level to magnetic couplings. Also, they feed information to potentiometers which then relay the information to the pilot.

So, to choose the right gauges, you should search for a quality company that produces them on the market. Searching on the internet, you will definitely find a website which will offer you the aircraft level Fuel Gauges that you need.

However, before you take them, you should check all necessary features and performances that these products offer. Also, you can always read descriptions, check the photos of the product and see the price.

Besides, all those information you should check the reviews and testimonials from previous customers. In this way, you will learn more about the company that is offering these aircraft Digital Gauges and also you will see if these are high-quality and safe products or not.

Why Fuel Flow Transducer is Beneficial in Aircraft?

Slim Line GaugesFuel Flow Transducers: The origin, advantage and current status

It was 1972 when that time leading U.S. avionics manufacturer Aerosonics began testing fuel flow transducers for use in general aviation aircraft. It was the first time someone took transducers seriously and tried to make one capable enough to withstand the vibrations of aircraft engines. It was important that it meets FAA regulations about blocked-rotor pressure drop without exceeding the 1.5 times the pressure drop of a spinning rotor. The chief advantage of a fuel flow transducer is that a blocked rotor does not affect the pressure drop in fuel-flow transducers. This imparts superior accuracy and an extraordinary repeatability for the devices and today, fuel flow transducers rule the roost when it comes to fuel flow measurement.

Fuel Flow Transducer: What does it do?

Unless the engine gets an even and steady flow of fuel, there will be a lot of hiccups and its overall performance will run downhill. In engine terminology, this is called knocking, but hiccups might occur due to a myriad other reasons too! To ensure that the flow of hydrocarbon fuels – most common being gasoline, kerosene, diesel and aviation fuel – is correct, you need to read from the fuel flow transducer.

Or, maybe there’s an excess amount flowing, resulting in a rich-burn engine. The fuel flow transducer comes handy again! It helps you to check fuel wastage.

Fuel Flow Transducer: How it works?

The fuel flow transducer works upon a vane RPM Sensor, located downstream behind the fuel filter and the Fuel Gauges. It usually stays in combination with ‘manifold air pressure’ or MAP.

The transducer produces a current-pulse signal from an opto-electronic pickup that’s fitted with a preamplifier. It has a 100 to 1 flow-range and gives out signals repeatedly and can measure fuel-flow down to 0.3 gallons/hour; however, the transducer bearing system is rated for continuous operation at the upper end of the flow range. It also conveys to the pilot the information about the health and performance of the engine and helps the pilot to keep the engine running within its operating limits to ensure maximum reliability.

Fuel Flow Transducer: Operating principles

• The liquid fuel’s rotational velocity is proportional to its flow rate. Upon entering the flow chamber, it moves along a helical flow-path before exiting vertically. It helps to vent any vapour bubble that might exist. This vapour-venting design requires the transducer to be positioned with electrical connectors pointing up.

• A neutrally-buoyant rotor spins with the liquid between V-jewel bearings and its movements are sensed when its notches interrupt an infrared light beam emitted by a LED with a phototransistor on the opposite side.

Note: Turbulence caused by valves or sharp elbows mounted close to the transducer inlet can affect transducer K-Factor and should be minimized.
