Ground Operation & Servicing
Ground Operation & Servicing is a core knowledge area on the AMT — General FAA written exam. This hub collects our 16 in-depth, ACS-aligned ground operation & servicing articles — each written in plain English and grounded in the official FAA handbooks. Work through them below, then drill the topic with practice questions.
Aircraft Towing Procedures and Precautions
Aircraft towing is a safety-critical ground operation requiring strict procedural adherence to prevent structural damage, runway incursions, and personnel injury during repositioning of aircraft on the ramp or in hangars.
Aircraft Parking and Mooring Techniques
Proper aircraft parking and mooring prevent structural damage and accidents on the ground — covering chocking, tie-down procedures, control locks, and hazard awareness every AMT must master.
Chocking and Wheel Chock Placement
Proper chock placement prevents unintended aircraft movement on the ground, protecting personnel, equipment, and the aircraft itself during maintenance and servicing operations.
Aircraft Fuel Contamination Identification and Prevention
Aircraft fuel contamination—water, sediment, wrong fuel type, and microbial growth—is a leading cause of preventable engine failures; AMTs must know how to detect, prevent, and respond to each threat.
Aircraft Jacking Safety and Jack Point Identification
Safe jacking of aircraft requires identifying approved jack points, following load limits, and using correct procedures to prevent structural damage or catastrophic collapse during maintenance.
Leveling an Aircraft for Maintenance
Leveling an aircraft is a fundamental maintenance procedure that establishes a precise reference datum for rigging, alignment, weighing, and inspection — and doing it wrong invalidates every measurement that follows.
Ground Support Equipment Operation and Safety
Ground support equipment (GSE) keeps aircraft serviced and ready between flights, but improper use causes serious injuries and aircraft damage — every AMT must know correct operation and hazard controls.
Fire Safety During Ground Fueling Operations
Ground fueling operations present serious fire and explosion hazards; AMTs must follow strict bonding, grounding, and safety protocols to protect aircraft, personnel, and facilities.
Aircraft Hydraulic Servicing Ground Procedures
Aircraft hydraulic system servicing requires strict contamination control, correct fluid identification, and precise pressure and fluid-level checks to ensure flight-critical system integrity.
Aviation Fuel Types and Color-Coding Standards
Aviation fuels are strictly typed, color-coded, and grade-marked to prevent misfueling accidents; understanding AVGAS and Jet-A differences is essential for every AMT and line technician.
Tire Inflation and Nitrogen Servicing Procedures
Proper tire inflation and nitrogen servicing are critical for aircraft safety; over- or under-inflation accelerates wear and can cause blowouts, while nitrogen prevents moisture-related corrosion and pressure fluctuations inside wheel assemblies.
Defueling and Fuel Sampling Procedures
Defueling and fuel sampling are critical AMT tasks that prevent fuel contamination and ensure aircraft airworthiness; improper procedures can introduce fire hazards or allow contaminated fuel into engines.
Static Electricity and Bonding During Fueling
Static electricity buildup during aircraft fueling can ignite fuel vapors; proper bonding and grounding procedures eliminate the voltage difference that causes dangerous sparks.
Aircraft Oxygen System Servicing and Handling
Aircraft oxygen systems demand precise servicing procedures and strict safety protocols; improper handling of high-pressure oxygen can cause fires, explosions, or hypoxia — making correct AMT technique a life-safety issue.
Engine Oil Servicing Types and Specifications
Aircraft engine oil servicing requires selecting the correct oil type and viscosity grade per manufacturer specifications — using the wrong oil can cause engine damage, voided warranties, or catastrophic failure.
Ramp Safety and Foreign Object Debris (FOD) Prevention
Ramp safety and FOD prevention are critical AMT responsibilities that protect aircraft, engines, and personnel from debris-related damage and ground operation hazards.
