Fuel Flow Instruments – How It Is Performing During the Flight

Fuel Flow InstrumentsSince the beginning of the Wright Brothers’ invention, providing pilots with useful flight information has been deemed of utmost importance. Even the Wright Brothers were concerned about the flight engine’s performance and flight progress. Since then, various flight instruments have come into existence to inform the crew about several parameters.

Information, such as; aircraft condition, engine performance, flight progress, the attitude in the sky, weather conditions, cabin environment, pressure, navigation, and communication; has always been considered of vital importance. Various companies are striving to produce instruments to improve pilots’ performance and safety during the flight.

Throughout aviation history, providing accurate and easily understood information to the crew has remained a challenge because the range of desired information is growing with time, so is the design and complexity of an aircraft.

Among such vital information, tools are fuel flow instruments which provide various types of information, related to fuel, to the pilot. Some of these instruments are briefly described below:

Fuel Pressure Gauge:

Fuel is pumped out by several tanks to the engine to maintain the desired output pressure. If fuel level falls below a specific limit in any one of the tanks the pilot must take immediate actions.

Fuel flow instruments allow pilots to pump, manage, and provide fuel to the propulsion system and Auxiliary Power Unit of an aircraft. Fuel instruments differ with the complexity of an aircraft as different kinds of airplanes require different levels of fuel performances.

Fuel flow:

This type of sensor is usually located in the lower part of the aircraft’s body, behind the fuel filter and instrument measuring the amount of fuel being delivered to the engine.

Those engines which have fuel injected sometimes have some amount of fuel that returns to the tank. Therefore, to get a more accurate reading the amount of fuel that is returning to the tank should also be measured with the help of a flow sensor.

The Electronic Fuel Flowmeter:

Liquid flow can be measured in various ways ranging from mechanical to ultrasonic/Doppler.

There are several products available in the aviation market, and most of them make use of a miniature turbine which mainly consists of a magnet and a fixed coil that is responsible for generating a pulse. This pulse is amplified and is delivered to another High Flow Transducer instrument, mounted on a panel, which converts the pulse reading into a more direct measurement of fuel flow in liters, or gallons, per hour.

Without a means of fuel flow indication, a crew must totally depend on the aircraft’s fuel EGT CHT Gauge, which are unbelievably inaccurate at times, or total air time, which also is only an approximate indication.

Therefore, you require fuel flow instruments that give you a more accurate reading about the amount of fuel flowing to the engines. For instance, the FS-450 Fuel Scan, provided by JP Instruments.


Buy Pre-Owned Single or Twin Engine Aircraft

EDM790J.P. Instruments announces their new and exciting range aircraft cockpit enhancements aimed specially at those planning to or who have purchased a pre-owned single or twin engine aircraft.

Buying a well maintained pre-owned aircraft is just part of the romance of owning an aircraft. Statistically, the age for new owners is less than the age of the former owners of the aircraft. Consequently, the new owners being more in tune with the times, desire a cockpit that is more informative, is colourful and preferably one that can sync with a laptop via a cable or download data to a USB stick.

California based JP Instruments does exactly that – design and manufacture state-of-the-art after market glass instrument panels for single and twin engine aircraft. Not only do these new instrument clusters replace several existing instruments, they provide a wider range of data with unmatched depth that is just not possible to get from the older instruments.

Moreover, the cluster is colourful, stores data which can be easily transferred via cable or USB to a computer.

With carefully planned, designed and engineered avionics, your latest pre-owned aircraft acquisition can look like brand new and at a price that will delight you. Aircraft cockpit upgrades are of course necessary for safety, economy and improving aircraft performance.

JP Instruments is proud to offer the latest Keyspan USB series of glass avionics instruments for most piston singles twins. JP Instruments can completely overhaul and upgrade your existing cockpit instrument cluster to take advantage of latest microprocessor and IC-based LCD / LED technology and software.

If you are planning to buy or have bought a pre-owned aircraft, JP Instruments is the best source for upgrading your old cockpit instrument cluster into a glass instrument cluster of the 21st century that provides you with the best situational awareness and easy-to-read digital interfaces and displays. Our instrument panels combine radar, terrain, weather and navigation maps into one space-saving device.

With the latest EDM series of JP Instrument clusters, you can see everything and react instantly. There are several highly capable and cost-effective avionics panels that offer advanced technology combined with innovative presentation methodology so the information is presented in an uncluttered and intuitive format. Our high-contrast, high-resolution LED/ LCD displays are readable in almost any lighting.

So if you are planning on upgrading your aircraft cockpit, think J.P. Instruments – we are the leaders in design and manufacture of World-Class aircraft instrument panels.

Avionic instruments & Aircraft Precision Products by JP Instruments

Slimline-220x2251Now a make-over for your aircraft cockpit – get rid of those monotonous grey instrument panels. Re-do your aircraft cockpit with colour to match your personality and add colourful avionic instruments and aircraft precision products from JP instruments.

Remember the first time you sat in the cockpit of your own aircraft? For months you were on a new high but overtime you must have wondered if there was anything you could do about the overall drabness of the cockpit.

Technology has advanced, aircraft cockpit instruments have become more accurate but the OEM products that come pre-fitted for single and twin engine aircraft are frankly, not only drab but fail to tell the entire story i.e. they do not cover every vital aspect of the aircraft engine.

Enter the after-market products dominated by California based JP Instruments that not only fill in the gap but make the aircraft cockpit a much livelier place.

Founded in the mid-80s by Joseph Polizzotto in California, J.P.Instruments has been designing and manufacturing state-of-the art avionic instruments and aircraft precision products that display a wider range of information that helps remove guess work from aircraft engine performance.

JP Instruments excels at producing after-market Single and Twin Aircraft Engine Management Systems, Fuel Flow Instruments, Slim Line Gauges, Probes and Sensors, Adopters and cables. They also manufacture scanners and also provide software for their EDM systems.

Their product list includes:

1. SINGLE Engine EDM-700/800, for 4,6,7,8,9 Cylinder aircraft engines

2. FS-450 Fuel flow instrument for single and twin flow (displays twice the data of FP-5L) and includes GPS interface, FloScan Transducer and Fire sleeve.

3. NEW EDM-900 with multi-colour HD display Primary with 4 Fuel level read outs available (No Remote boxes, this is a all in one instrument). The EDM-900 comes standard with a full-colour VGA bar graph which assists with (ROP/LOP) leaning. Additionally, the bar graph has both “normalized” and digital readout of EGT and CHT above each column and in the message area on a single screen. No other bar graph in the industry comes close to providing the number of functions, the EDM-900 offers. The EDM 900 comes with a 3 year Warranty.
