How Aircraft Fuel Flow Indicators Work?

Aircraft Fuel Flow IndicatorsAircraft’s have two wings and a fuel tank in each of them. Some aircraft are adopted for long duration flights and may have more than two fuel tanks. Having one fuel flow indicator for one tank is easy to understand but ever wonder how a single fuel flow indicator can provide information regarding fuel levels in two or more tanks? Read on.

In days gone by, an aircraft fuel flow indicator was basically an adaption of the vehicle fuel flow indicator. It had an analog system (i.e. mechanical) via a micro float valve and a tiny bucket wheel. As the fuel flowed, the bucket wheel rotated inside the fuel pipe and provided a reasonably accurate fuel flow rate. Meanwhile the float valve gave an actual indication of who much fuel was left in the tanks. The fuel balance indicator and fuel flow indicator looked a little more complex than your average car fuel indicator but the essential functionality was the same.

The float valve position and the rotation rate of the bucket wheel was converted to an analog indication via a drive magnet. As you can imagine, this was a very delicate arrangement.

Some 20 years ago, the humble fuel indicator and fuel flow indicators were upgraded to electrically powered indicator. This brought in a level of accuracy to the fuel indicator and fuel flow indicators. The system no longer relied on metal wires or cables connecting the float valve or bucket wheel to the actual fuel indicator and fuel flow indicators. These metal cables were prone to get tangled and during a turbulent flight, were known to get tangled making them highly unreliable. Which is why in WWII war movies, you often saw pilots tapping at the fuel flow indicator to make sure nothing were stuck.

The electrical system did away with the cables and instead worked by calculating the capacitance. Basically, the electrical fuel indicator and fuel flow indicators used a capacitor to do the calculation. Here’s how it worked – the capacitor stored an electric charge. How much of this electric charge it stored depended on the level of the fuel in the aircraft.

More the fuel, higher the stored charge – very simple when you think about it. In turn, the capacitance charge level is converted by the fuel gauge into an analog or digital read-out.

Roughly 10 years back, the electrical fuel indicator and Fuel Flow Indicators were swapped out for a new innovation – the digital fuel indicator and fuel flow indicators. Here’s how the digital fuel indicator and fuel flow indicators worked:

When aviation fuel flowed through a pipe, it could be accurately measured via the Aircraft Electronic Data Management Systems (EDMS). The output could either be displayed as a bar graph or as a number (depending on the pilot preference). Modern EDMS not only indicated fuel levels and fuel flow levels with a high degree of accuracy, they could provide other valuable information too such as, distance-to-empty and with a GPS plugged in, they could even indicate whether the plane had enough fuel to make it to a specific destination.

In the United States, J.P. Instruments are the premier manufacturers of modern day fuel indicator and fuel flow indicators. More information here: Error margin would indicate a fuel leak and trigger an alarm.


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.

J.P.Instruments has been around since 1986 and has provided excellent quality monitoring systems. The CEO who is also the founder was a mechanical engineer working with aircraft and also pursued work as a test engineer. He created his first scanner system for his own aircraft. The website for this company’s products is filled with useful information, customer reviews, a large selection of products and much more.

Get Accurate Information & Save Panel Space in Aircraft with Slim Line Instruments

Slim Line InstrumentsAlmost all aircraft panels are required by Federal Aviation Regulations (FAR Part 91) to have room for a few obligatory instruments. The complete list of the instruments necessary for legal flight is quite extensive so saving space is a priority. JP Instruments always sets the bar for high-quality products for a great price.

Slimline is the best brand that one can have on their aircraft. It has so many advantages that one would need to travel safely without the added weight of large mechanism inside the plane. They have a whole line of aircraft instruments called Slimline that splits the gauges into individual pieces that are easy to install. The gauges are all bright red, easy to read; they can be purchased either individually or together in groups. SlimLine supplies for Experimental and Certified, FAA-approved aircraft.

These instruments save the needed space while still giving accurate information that is up to date. The lack of instrument panel space is usually not a problem for an average two-seater aircraft with seating that is side-by-side. It is, however, a common problem with single-seaters and two seaters with tandem seating. 24 inches wide is hardly big enough to accommodate a set of radios, switches, Slim Line Instruments and other controls.

The equipment will be able to monitor the temperature, oil flow, and overall functioning of your engine. It allows for the pilot to monitor progress and functionality as they do work piloting the plane. There is no need to have to worry about changing temperatures and fuel flow. The management system is combined with quick response sensors of different kinds to display accurate engine data in real time. The displays can be easily programmed and therefore any pilot can easily program them straight from the front panel. The upper (I.e. engine temperature) and lower limits (i.e. fuel) can be monitored and should the engine exceed any of the limits, there will be visual and sometimes audio warnings sent to the pilot that is difficult to ignore.

The easy to understand navigating panels will allow one to operate not only the machine but the plane to the best extent possible. There is both the single engine and multiple engine management systems available. This variability allows for accommodation to almost any kind of Aircraft Engine Data Management. The Gauge can not only be updated two times per second but is also accurate in terms of +/- 1 RPM. It has an “over boost” alarm, which will help a person wake up in the morning or act as a reminder for the most important daily tasks. The resolution is impressive at 0.1 inches of Hg.

Aircraft Engine Analyzer – Best Engine Monitors To Keep Your Engine Healthy, Efficient & Safe

Aircraft Engine AnalyzerIt’s uncommon for an aircraft engine to simply just stop working; there’s a reason or there’s a chain of events that cause a mechanical breakdown. There are certain components of the engine that fails and cause power loss. The most common ones are the crankshaft, main bearings, pistons, cylinders, magnetos and the connecting rods.

Usually, the bottom portion of the engine is pretty sturdy and solid to withstand a lot. The top part of the engine which includes the pistons, cylinders, valves, gears, etc. is a lot less sturdy. This is where the engine analyzer comes in handy. It does its part in catching problems with these more at risk components early on to save the engine from a bigger and more expensive destruction. An engine having a fix up as many times possible is common and many of the components aren’t replaced. This means they have to tolerate many TBOs (time between overhauls). If these components happen to fail, they usually do so early on in their life from either being defective or overheating.

The best type of analyzers are the ones that do long-term performance logging and allows data to be downloaded. Technicians can then create reports from this raw data. These reports are useful to look at and provide a visual of the engine’s condition. They also can show an in-depth look if something goes wrong or an accident happens.

The best kind of Aircraft Engine Analyzer is the one that displays cylinder head temperature (CHT) and exhaust gas temperature (EGT) on all present cylinders. Unlike the cheap model that will only read and display data on one cylinder which is usually the one that is closest to the firewall and becomes the hottest. When it comes to the ideal brand of engine analyzers, JP Instruments is the industry standard. Based in California, this company is a pioneer in the digital engine technology and equipment market.

The company has a large selection of single- and multi-engine analyzer. Their most advanced monitor is called the EDM-930 which is endorsed as the main flight gadget to use. With this device on board, you will be able to remove the old engine gauges and create more space in your panel. It does countless tasks such as tracking, recording and storing all engine data. This component also includes an interface to popular GPS models, alarms that can be programmed in multiple ways, Hobbs meter, fuel totalizers and a plenty of other important features. With this device, there will be no short sidedness in identifying the problem or taking the shortcut route in data collection.

Importance of an Aircraft Sensor System in Airplane

Aircraft Sensor SystemsAircraft sensors are essential to get data from the outside world. In this type of airplane, it is common to find the sensors dedicated to ice detection or the calculation of the position with respect to a point of origin. Also, they have sensors of altitude, pressure, speed, the angle of attack, etc. if the sensors fail or break down, the planes become disoriented.


The aircraft uses hundreds of kilometers of sensors throughout its structure and for different types of systems and components. This allows the crew, and maintenance personnel to detect even the slightest flaw that a condition or flight arrangement can pose and allows pilots to make decisions well in advance depending on the type of system or component that is close to a failed or has already failed.

The possibility of having real-time information of all the important components and systems of an aircraft generally allows crews to reconfigure their aircraft or to prepare them for a special, abnormal or emergency procedure with accurate information on the failure and about the implications that it has on the operation of its airplane, and insufficient time to allow a safer maneuver.

For example, an oil leak in an engine could be detected in time by the crew and allow them to take the necessary actions to avoid a major problem, such as overheating or fire in flight.

Sensor operation system

When the aerial platform is an aircraft, the real aperture radar SLAR (Side Looking Airborne Radar) is used and consists of a pulse of electric energy emitted in the frequency range of the microwaves and whose reflection in the ground is collected again by an antenna located on the plane itself. The main drawback is its low spatial resolution.

One or more sensors are located facing the relative air. The probe detects the Aircraft Flow Sensors in relation to the differential pressure. The vane acts as a supporting surface and aligns with the relative airflow.

Most systems are equipped with additional devices such as electric vibration systems on the flight controls to warn of the imminent loss of the aircraft. In addition to the corresponding sound and light alarms.

Commercial aircraft have three sensors, two on the right side and one on the left side, shaped like a weather vane.

Over the years the Aircraft Sensors have been evolving and will continue to evolve, are a great help and a key element. These sensors are very important and essential nowadays, they are a great element that can help pilots to avoid any problem, be more aware if there is a complication and try to solve any complication keeping most of the safety for their whole crew and passengers as well.

The Functions & Working of An Aircraft Sensor Systems

Aircraft Sensor SystemsAn aircraft sensor system is an element of much importance. They are dated ten years back of use. However, modernization continues as the years unfold. They are of affordable prices and almost weightless as they continue to oversee the aircraft’s overall activities. This reduces the time taken to maintain.

The temperature sensors are found in the temperature detector. Thermal reading of given units is calibrated by these sensors. The elements recorded include temperatures of the fuel, engine oil, exhaust, cylinder heads etc. once current passes through wherever the sensor is placed, the resistance’s alliteration is taken as the temperature of that unit.

Crafts are equipped with sensors that measure the liquid levels just as one can tell the liquid level of a car whether full, half or empty. In this case, the sensors are placed in various elements, this allows the captain to get the information from the liquid level sensors.

The flow monitor sensors are installed in pipes that carry fluids. This measures the rate of flow of various fluids such as the aircraft oil. This should be kept under keen observation. They are also connected to the temperature gauge of the exhaust gas and that makes them differ from liquid level sensors.

Status confirmation sensors are also important in telling the status of aircraft elements that are meant to move with a purpose such as shutting or opening such as doors, gears among others. These sensors can as well be called proximity sensors. Pilots make final decisions depending on the outcome results of these sensors once they give a message, and decide whether to land the aircraft or proceed.

Pressure sensors are of too much importance too. The hermetically sensing element is provided in the pressure switches that help to indicate pressure below or above a certain point at the location of sensing. The element is installed directly into tanks, gearboxes, pipes, ducts, sumps, and reservoirs on military and commercial aircraft and spacecraft. It indicates gauge pressure values as needed for various applications.

There are other various types of aircraft engine sensors such as the RPM Sensor also known as the Revolutions Per Minute where there is an involvement of a magnet which has a limit of rotation. As the years go by, more and more advancements come along. Recently a wireless sensor was developed by the FLITE-WISE project to facilitate the monitoring of aircraft. The new system is expected to bring weight and cost down and will be in use within the next four years.

In conclusion, it can, therefore, be seen that captains depend highly on these Aircraft Sensor Systems for secured flying, where a slight problem might lead to complications. All sensors are now seen to be working together having a relevance to the assurance of safety.

How Aircraft Engine Monitors Works?

Aircraft Engine Monitors WorksAn aircraft engine provides mechanical power by propelling the craft forward with the help of a motor giving it a thrust force making move forward. Most engines include the gas turbines or piston engines that work together with the wings to make the craft fly.

An aircraft engine uses the same principle as the car engines of burning fuel with air in cylinders but instead, an aircraft uses a tube in the straight line carrying all the four steps. A turbojet is an example of a simple form of jet engine type which draws in air through the inlet which is then compressed by the fun then combusted with fuel then comes out of the outlet as exhaust at the back moving so fast.

Aircraft engines are usually equipped with fans in the front of the engine which forces cold air through the inlet to the engine. A compressor is a second fan that pressurizes the air by compressing it and therefore making it hotter. A liquid fuel known as kerosene is sprayed from the fuel tank to the engine. It is in the combustion chamber that the kerosene from the fuel tank mixes with the air from the compressor and burns vigorously increasing the temperature of the exhaust gas. The mixture reaches an extremely high temperature of about 1000¬ degree Celsius.

There are turbine blades spun by the exhaust gases passing through them. The turbines, therefore, use the exhausts energy making them gain energy from the gas, and this cools the gases and reduces their pressure because they lose the same amount of energy.

The long axel that runs along the engine connects the turbine, the compressor and the fan making them rotate at the same time as the turbine spins. The exhaust nozzle makes the exit of the exhaust gases. This helps to accelerate the gases to a speed greater than 2200km/h just like water accelerates dramatically when passing through a narrow pipe. This makes the speed of the exhaust gases double the speed of the air entering through the front part of the Single Engine Data Analyzer; this makes aircraft engines more powerful. Afterburner is an improvisation that makes the military jets have an extra thrust. This works when fuel is sprayed into the exhaust jet. The exhausts gases must have to get out with greater speed backward than the speed of the plane because the aircraft itself is much heavier than the gases produced.

The power produced by an Aircraft Engine Monitors is rated as power sent to the propeller which is basically crankshaft RPM multiplied by torque. The engine power is converted to thrust by the propeller where the thrust is basically a function of the pitch of the blade relative to the aircraft’s velocity.

As the years unfold, more and more technological improvements on the aircraft engine advance. Modern aircraft are now about 100 times powerful than the early ones.
