On a typical passenger aircraft, the fuel is contained. “We’re making it easier than ever to address this through automatic sensing, as a critical and efficient part of flight line testing. The system comprises fuel quantity indication, distribution, refueling, defueling and fuel jettison. This new system, which is manufactured by Simmonds Precision, replaces the analog fuel quantity indicating system gages used on earlier Hercules aircraft and incorporates many advanced features. “Contamination in the fuel tank can cause an incorrect fuel level indication,” said Guy Hill, Director of Avionics Test Products, VIAVI. On FUEL ECAM page, if you see an amber line appearing. During this time, VIAVI has supported system testing of over 200 aircraft platforms, from the Airbus A300 to the V-22 Osprey. The Center tank indication is boxed amber if both Center tank pumps are failed or switched off. This portfolio has supported fuel quantity system testing of rotary and fixed-wing aircraft for over 30 years as part of Goodrich Aerospace, then Aeroflex, and now VIAVI. The PSD90-3 replaces previous test sets including the PSD30-2AF, the PSD60-2R, the PSD60-1AF and the PSD90-1C. PSD90-3 is suitable for flight line testing on battery power or bench testing on external power. The RG55 Selector Switch is used to select a reading of any individual tank or a total of all of the tanks.
The PSD90-3 Fuel Quantity Test Set accesses the Fuel Quantity Indicating System (FQIS) through an interface which is unique to each aircraft. For example, if the fuel tank maximum capacity is 10,000 KG, then the tolerance of the gauging.
FUEL QUANTITY INDICATING SYSTEM FULL
During normal capacitance measurements, the contaminated fuel probe detection function will automatically alert the user via a Percent of Error indication on the display and with a Contaminated Fuel Probe Detected LED on the front panel. A magnetoresistive sensor measures the angle of a magnetic field that rotates as a function of the position of a float, thus indicating the quantity of fuel in. The total tolerance for the FQIS system is based on a full tank. The PSD90-3 Fuel Quantity Test Set provides users with two methods, Auto and Manual, for detecting and isolating contaminated fuel probes caused by particulates, water, microbial growth, or other sources of contamination. Fuel quantity data, measured by probes in each tank, is fed to the fuel quantity processor where it is corrected for density then displayed on a Fuel Quantity. These microorganisms feed on the hydrocarbons in the fuel to produce a substance that can reside on fuel probes, causing a fouled probe which can lead to incorrect fuel level indication, a problem that can go undetected for some time. Particulates and moisture present in fuel significantly promote bacteria and fungi growth. Uniquely, the test set includes automatic detection of probe contamination, an issue for commercial and military aircraft worldwide. The PSD90-3 will test any AC or DC capacitive fuel, water, liquid oxygen (LOX), or engine oil system. The test set allows the user to test, troubleshoot and isolate fuel system issues, calibrate fuel quantity indicators and detect contaminated fuel probes. An example is the aircraft fuel quantity indication (FQI) system, of which the design is strongly dependent on the tank geometry definition.

(1,814 kgs.) t e total indicated fuel could be as l o w as 1,300 lbs. For example, if the actual total of fuel in the four main tanks for landing is 4,000 lbs. (plus or minus 3 percent o f t a n k full scale reading) when determining the minimum indicated fuel for landing. However, operators should consider the possible fuel quantity indicator error shown.
Regarding the above statements, A micron is a 1/1,000,000th of a meter. A fuel heater operates as a heat exchanger to warm the fuel. Gas turbine engine fuel systems are very susceptible to the formation of ice in the fuel filters. Fuel quantity indicator Definição1 The indicator and low level warning system used to indicate the quantity of fuel in the tanks.ĬONT: Minimum fuel for landing can best be determined by each operator due to differences in weather conditions, air traffic control delays, airline pol icy, etc. Study with Quizlet and memorize flashcards containing terms like 1.
