How Do Airplane Fuel Gauges Work in an Aircraft?

Airplane Fuel GaugesAirplane fuel gauges are somewhat similar to vehicle fuel gauges in that they both indicate the quantity of usable fuel present in the fuel tank. However, airplane fuel gauges work at a more complex level simply because aircraft carry more than one fuel tank and they also have more than one engine. Besides, reading fuel levels becomes complicated due to the fluctuating fuel density resulting from the changing aircraft altitudes.

To explain the workings of an airplane fuel gauge in a simplistic manner: a float level gauge is fitted to each of the fuel tanks in the aircraft. These gauges feed the information pertaining to fuel level in each tank to magnetic couplings and potentiometers which in turn pass on the information to the aircraft fuel gauge. However, the sloshing liquid with fluctuating density in multiple tanks make the work of airplane fuel gauges quite complicated. Modern aircraft technology however, has been able to achieve an advanced level of accuracy in the complicated world of aircraft fuel level reading.

Basically, there are three types of airplane fuel gauges that are used in aircrafts of today, namely,

1) mechanical airplane fuel gauge
2) electric airplane fuel gauge, and,
3) digital airplane fuel gauge, which is the choice for the latest model of airplanes.

The Mechanical Airplane Fuel Gauge is fitted with a cork which is attached to a lightweight aluminium pipe. The cork goes up or down with the fuel level. The pipe is attached to a stainless steal gear system which converts the motion of the cork into a circular movement showing “full” or “empty” indication of the fuel tank.

The mechanical fuel gauge is a simple device found in the old aircraft models. The disadvantage of mechanical fuel gauges is that there are too many moving parts that can get stuck or jam up due to the aircraft’s movement and vibration.

Electrical Airplane Fuel Gauge is also known as capacitance meter and uses a capacitor, an electrical amplifier and a fuel gauge to give a reading of Aircraft Fuel Flow Indicator in the tanks. The capacitor stores an electric charge, the size of the dielectric which is either the fuel in the tank when full or the air in the tank when it’s empty. The fuel gauge in the cockpit of the aircraft reads the capacitance charge and displays the information.

The Digital Airplane Fuel Gauge is the latest technology being used to calculate the level of fuel in the airplane’s tanks. When the aircraft is fuelled up for a flight, the pilot enters the quantity in each tank via a touch screen on the Digital Fuel Gauges. The flow rate of the aviation fuel through the outlet pipe is accurately measured and the onboard computer in the plane’s electronic management system calculates the quantity of fuel remaining in each of the tanks and displays it in digital form or bar graphs. Based on the consumption of fuel and the quantity left in the tanks, the aircraft’s electronic management system can calculate whether the plane has sufficient fuel to reach its destination.

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.
