By Editor 16-Jul-2021


The ADL has manufactured indigenously designed four types of Fuel Quantity Transmitter probes (FQT) and one Electronic Box for Fuel Quantity Measuring System (FQMS) of civil version Dornier-228 (Hindustan-228) for the first time.

The FQT probes consists of two coaxially arranged aluminium tubes which acts as a capacitor which is sensed by electronic circuit placed in a sealed compartment against any leakage of fuel. Electronic box provides the relevant power supplies and processing of data for indicators and automatic control refueling operations for preset levels. The system is having an accuracy in the range of +0.5 microsecond of time period, one of the highest in aircraft industry.

These are one-is-to-one replacement of the original licensed version LRUs thus providing a boost to the Aatmanirbhar Bharat drive. The Division has also been successful in getting DGCA, CAR 21 approval for production of these units. Through this enhancement, five type of LRUs have got added in the division's civil capability list. Now Division can undertake new production of these LRUs to for civil use Dornier aircraft.
