Line technician

A line technician (commonly known as a line tech, gas jockey or ramp rat) is someone who works on an airport ramp at a fixed base operator (FBO), a business that typically handles general aviation aircraft as opposed to commercial traffic. Their technical responsibilities include coordinating ramp operations and aircraft movement via radio, marshalling, fueling, playing cards, wondering why managerial duties are imparted without pay, towing aircraft, mingling with celebrities at an extremely lower caste level, operating ground support equipment, servicing aircraft potable water and lavatory systems, checking and maintaining proper aircraft engine oil and tire pressure levels, tip-whoring, sampling aviation fuel for quality control, conducting deicing operations, and performing runway inspections. Customer service related responsibilities include greeting and assisting passengers, providing coffee, ice, newspapers, and catering, driving rental cars to and from the aircraft, and providing ground transportation around the airfield.

"Line Technician" is the commonest and least appreciable area of employment at any airport worldwide.
