Aircraft refueling procedures for airplanes and helicopters


ISOIL has developed specific refueling systems for the aviation sector, designed explicitly for refueling helicopters or small aircraft, in airports and elsewhere.




Procedures for connecting and disconnecting fueling equipment to the aircraft or helicopter


When it comes to aircraft refueling procedures, the proper connection and disconnection of fueling equipment are crucial to ensure the safe and efficient transfer of fuel. Follow these steps for connecting and disconnecting fueling equipment to the aircraft or helicopter:


Connecting Fueling Equipment

  • Position the fueling vehicle or equipment in the designated refueling area, ensuring it is stable and secure.
  • Wear appropriate personal protective equipment (PPE) such as gloves and safety goggles.
  • Ensure that the fueling equipment is compatible with the aircraft or helicopter, taking into consideration the fuel type, flow rate, and any specific requirements.
  • Inspect the fueling equipment for any signs of damage or leaks.
  • Approach the aircraft or helicopter cautiously, keeping a safe distance from any rotating parts.
  • Identify the fueling point on the aircraft or helicopter, which is typically marked by a clearly visible label or indicator.
  • Connect the fueling hose or nozzle securely to the fueling point, following the manufacturer's instructions.
  • Double-check the connection to ensure there are no leaks or loose fittings.


Disconnecting Fueling Equipment

  • Before disconnecting, ensure the fueling process is complete, and all required safety protocols have been followed.
  • Shut off the fuel supply from the fueling vehicle or equipment.
  • Release any pressure or vacuum in the system to avoid spillage or fuel spray.
  • Carefully disconnect the fueling hose or nozzle from the aircraft or helicopter, following the manufacturer's instructions.
  • Inspect the fueling equipment for any signs of damage or leaks.
  • Safely stow the fueling equipment, ensuring it is protected from environmental factors and secured for transport or storage.
  • Move away from the aircraft or helicopter and any fueling equipment, maintaining a safe distance.


ISOIL Solutions for Aircraft Refueling

ISOIL is a recognized provider of advanced fuel measurement refueling solutions for the aviation industry. Their range of products ensures accurate fuel monitoring, efficient refueling processes, and enhanced safety. Let's explore some of the ISOIL solutions commonly used in aircraft refueling:


PD Meters

ISOIL PD (Positive Displacement) meters provide precise volumetric measurements of fuel during refueling. These meters are highly accurate, even in challenging environmental conditions. They ensure reliable and repeatable measurements, minimizing errors and improving the overall refueling process.


Pulse Emitters

ISOIL Pulse Emitters generate electrical pulses proportional to the flow rate of fuel passing through the meter. These pulses can be used for monitoring and control purposes, enabling efficient management of fuel usage. Pulse emitters enhance data accuracy and facilitate real-time monitoring of fuel consumption.


VEGA T2 Electronic Counter

The VEGA T2 electronic counter excels in both metrological functions and perfectly interfaces with various signals on the vehicle and external devices. This advanced register and controller is essential for aircraft refueling and defueling. In fact, it is capable of handling both Underwing and Overwing refueling simultaneously. It can connect with the On Board Computer and external devices for data management.


Large-Digit EX Display

The Large-Digit EX Display is a robust and weather-resistant unit designed for outdoor use in aircraft refueling environments. It provides clear visibility of fueling data, including fuel volume, flow rate, and other essential parameters, and enhances readability, ensuring accurate fuel monitoring in various lighting conditions.



ISOIL Printers can generate detailed reports and receipts during the refueling process.

These printers provide a convenient means to document refueling operations and maintain a record of fuel transactions. They are designed to withstand the demanding conditions encountered in aviation refueling systems.
