The Functions & Working of an Aircraft Sensor System

Aircraft Sensor SystemIn the flight economy, an aircraft sensory system is one element of ultimate importance. They have been used over the years, to date. However, they continue to be modernized as the years go by. Found at quite affordable prices in the market, not to mention almost weightless, they continually oversee the overall activities of the aircraft. This is beneficial as it reduces the maintenance time taken.

Checks and Balances on the Temperature

In the resistance temperature detector, the temperature sensors are found therein. These sensors work to calibrate the thermal reading of given units in an engine of an aircraft. The recordings of elements such as:

• fuel temperatures
• cylinder heads
• exhaust
• engine oil

among others, are done by the temperature sensors. It works in such a way that wherever the sensor is placed, once current passes through it, the alliterations in the resistance is then tallied as the temperature of that particular unit.

Sensors for the Liquid Levels

Just how you can tell the fuel levels in your car, whether you have a full tank or your car will come to a halt soon, then somewhat the same applies in this case. Here, the sensors are directly installed to the various elements in the aircraft; for example inside the reservoirs. The sensors may not be at one single place but rather dispersed within the liquid. When the captains look on to the dashboard, they will be able to access the information conveyed by the liquid level sensors.

Flow Monitor Sensors

The flow of the liquids then ought to be in kept under close observation at any given second. For these sensors to function, they are installed directly into the pipe that will be expected to carry the necessary liquid. The rate of flow of the aircraft oil is now measurable here. Mounted in the same manner as the liquid level sensors, they have been seen to have the exception of it being connected to the exhaust gas temperature gauge.

Status Confirmation Sensors

These sensors are formally known as proximity sensors. They are quite essential in detecting the status of certain elements in the aircraft that are meant to open or shut; for example:

• door
• Landing gear door among others.

Once they have passed a given message, the pilots will then know how to aid the situation: whether to proceed or land the Aircraft Level Sensors.

Other Aircraft Engine Sensors such as the RPM (also referred to as ‘revolutions per minute’) where a magnet is involved and that it ought to rotate within a given limit; that and the pressure sensors used to determine the pressure of one element, are you in conjunction with the ones explained above in order to be able to ascertain an aircraft’s safety.

In conclusion, therefore, it can be seen that the pilots highly depend on these sensors for re-assured flying. A slight malfunction could lead to various complications. The sensors all seem to have a candid relevance to the determination of the safety of the flight. They can all also be seen to work together each one depending on the other just like the nervous system in the human body.


JP Instruments Twin Engine Mgmt Systems for Aircrafts

During the 30’s when aircraft instrumentation first began to make their appearance, aircraft engine management system meant an airspeed indicator, turn-bank coordinator, manifold pressure, altimeter, engine RPM, compass, and the climb-dive indicator.

Navigation meant a magnetic compass mounted in front of the pilot and there was another compass in his pocket just in case he had to bail out which back then, was quite frequent. Pilots flew a couple of hundred feet above tree tops so they could navigate by roads, landmarks and railway tracks. Pilots flew at night only if they had no option. More often than not, they would miss their destination by hundreds of miles and also required bonfires on the field during landing. Fatal accidents were routine and the plane would invariable have to be written-off.

We’ve come a long way from aircraft management systems of the 30’s. Today aircraft engine management systems especially the aftermarket ones of the type designed by J.P. Instruments – World leader in twin engine management systems; include real time information such as OAT, IAS, ALT and ROC. Vibration data monitor are also a new development and could help detect structural fatigue before it becomes dangerous.

Of course, development of aircraft twin engine management systems at J.P Instruments did not happen over-night. Joseph Polizzotto (Joe) founded J.P. Instruments after he successfully planned and designed the ‘Scanner’ in 1979. The Scanner was a revolutionary new aircraft instrument that automatically and constantly tested and displayed aircraft engine temperatures.

Soon, a whole series of new aircraft instruments were developed and there was no looking back. Their star instruments include intelligent fuel flow gauges, engine data management systems, GPS moving maps and so on. Being innovative engineers as well as experienced pilots helped develop aircraft instruments that really mattered and help improve flight safety.

Today, aircraft Twin Engine Management Systems designed by J.P. Instruments include the EDM 760, EDM 790 and EDM 960.

The EDM 760 is one of the most advanced and accurate piston engine-monitoring instruments on the market. The EDM 760 will monitor your engine parameters three times a second and will warn you instantly if any parameter exceeds the programmed limit. Computer Assisted Diagnostics for troubleshooting entire system from the cockpit, all programming is done from the Front Panel, using two simple buttons. It has 29 alarms, including EGT Differential, Alternator Voltage, Fuel Flow and Shock Cooling.

The EDM 790 on the other hand, monitors twenty-four critical Aircraft sensor systems parameters four times a second, with a linearized thermocouple accuracy of better than 0.1 percent or 2 F° which has been verified and tested by the FAA and thus TSO’d (Technical Standard Order).

The EDM 960 is a state-of-the-art certified primary flight instrument. With the EDM 960 on board your twin engine aircraft, you can remove many of your old engine gauges, and open up valuable space in your panel. Featuring one DAU per engine, only 2 wires run back to the display in the cockpit. No thermocouple wires in the wings! Fly with confidence as your EDM960 acts as your full time on-board flight engineer.

Twin Engine Aircraft Monitoring Instruments

Aircraft Monitoring Instruments2Let’s face it – twin engine aircraft designers and manufacturers rarely sit in the cockpit of their own aircraft and fly it. Consequently, they have little or no idea as to the effectiveness of the instruments that they install in their aircraft. Besides, with “reduce costs and increase profitability” being their motto, they tend to be very minimalistic in their approach to twin engine aircraft monitoring instruments than is good for the new aircraft owner.

Almost every new owner feels the need to either replace several of the existing twin engine aircraft monitoring instruments or add new instruments that provide vital information that helps keep the engine fine-tuned, reduce fuel bills and makes it easy for post-flight analyzes (through data logging).

J.P. Instruments; manufacturers of after-market aircraft monitoring instruments, not only provides stand-alone engine monitoring equipment, they have also lately developed engine monitoring instruments that can be integrated into MFD’s (multi-function displays).

Around 75 years ago, twin engine aircraft monitoring instruments basically meant cylinder head temperature and exhaust gas temperature indicators and even these were primitive and not 100% accurate.

Today, J.P. Instrument provides fuel flow monitors, manifold pressure and Tachometers that help analyze fuel mixture distribution, detecting maladjusted or dirty nozzles, malfunctioning carburettor floats, prop governor adjustment etc.

Other vital after-market twin engine Aircraft sensor systems monitoring instruments include Turbine Inlet Temperature monitors (for turbocharged engines), Electrical Voltage & Amperage instruments, air data, vibration data and latest technology aircraft performance sensors.

The Turbine Inlet Temperature instrument monitors the magnet timing and helps run the power plant and exhaust system more efficiently. The VOLTS & AMPS monitor provides vital information on the charging system especially for aircraft with dual alternators and dual bus electrical systems.

Twin engine Aircraft Flow Sensors monitoring instruments can immensely benefit from air data monitors that help monitor vital statistics such as OAT, IAS, ALT and ROC. Vibration data monitor are also a new development and could help detect structural fatigue before it becomes dangerous.

J.P. Instrument not only manufacturers all these instruments, they also manufacture instruments that feature data logging – after all, the pilot can’t really be expected to observe and remember everything that happened during the flight. Modern after-market instruments come equipped with large built-in hard-drives and can store large volumes of data. These drives can be removed or data downloaded. Some instruments come equipped with Micro SD cards.

As owner of Twin engine aircraft, you might also want to install a good LCD / LED display panel. These panels help display information in an attractive, easy-to-read format.
