Calibration of Measuring Devices on Ground Service Equipment

Ground Service Equipment (GSE) is the support equipment which is usually mobile and some of them are self-propelled found at an airport, usually on the apron, and the servicing area along with the terminal. This equipment is used to service the aircraft between flights and also to perform routine and emergency maintenance that may be required on the aircraft while it is parked at the tarmac.

 

Ground handling equipment manages many service requirements of an aircraft between the time it lands at the airport and the time it departs for its next flight. Speed, efficiency, compactness, and accuracy are important design features in-ground handling equipment to reduce the turnaround time of the aircraft.

 

Aviation GSE comprises a diverse range of vehicles and equipment necessary to service or perform maintenance and other ground-based operations. The wide range of activities associated with aircraft ground operations leads to equally wide-ranging equipment which includes electrical power carts, air-conditioning carts, potable water tankers, waste drainage vehicles, engine, fuselage examination equipment, various types of dollies, carts, and lifting jacks.

 

Calibration of Your Measuring Instruments Installed on GSE is Important

There are various types of Ground Service Equipment on the apron and most have some kind of measurement equipment as part of their design. This equipment may include flow meters, temperature, and pressure sensing devices. Calibration of these devices is necessary so that GSEs may perform their functions accurately.

 

Measuring equipment with prolong usage loses some accuracy. Its measurements start to show some drift from the real value. This may be due to weather-related corrosion, physical damage, malfunction, overuse, or misuse. Undoubtedly, it is important to make sure that all the measurements are always accurate. Proper calibration is the key to ensure good measurement accuracy.

 

In the aviation industry calibrations are vitally important, as flight safety is the paramount consideration in all aircraft related activities. To be confident that the parameters being measured are correct, there is an ongoing need to maintain the calibration of equipment routinely, as per industry standards.

 

Calibration is a process of comparing one measurement device with another piece of equipment that has been calibrated and referenced with known values. This process either validates or corrects the device under test based on the comparative result with the reference device. The reference device is referred to as a calibration standard. Calibration quantifies and controls errors or uncertainties within measurement processes to an acceptable level.

 

Calibration of Flow Measurement

Flow measurements are based on a calculation of the quantity of fluid transferred or passed through the flowmeter with the amount determined by the standard. Standards can be set based on mass or volume. From the measured quantity, the required mass or volume quantity can be determined, from the fluid density values determined by the test flowmeter. Standards can be static or dynamic and depending on the performance and end-use of the flowmeter. Flowmeter calibration should cover a large flow rate range for the flowmeter, and its performance should be defined over that range.

 

Calibration of Temperature Measurement

Various types of temperature sensors are used for temperature measurement on GSEs. To calibrate the temperature sensor you have to dip the sensor in the fluid and compare its readings with a known temperature. For industrial and professional calibration, typically temperature baths or dry-blocks are used. These can be programmed to heat or cool the temperature into a certain set point. In some industrial applications. If the temperature sensor is out of calibration beyond the expected range, it is discarded and is replaced by a new temperature sensor.

 

Calibration of Pressure Measurement

A pressure gauge is a fluid intensity measurement device. A pressure comparator is used to test the pressure gauge.  A digital display shows the pressure and allows calibration of the gauge to an accuracy of ±0.1%. meeting the industry standards.
