GCAA Ghana AME Exam study guide
GCAA Ghana AME Exam · Work through your exam, one topic at a time.
The GCAA Ghana AME Licence Examination is the basic-knowledge assessment set by the Ghana Civil Aviation Authority for people seeking an Aircraft Maintenance Engineer licence - the certification that allows an engineer to certify maintenance work on civil aircraft under Ghanaian oversight. Candidates are typically aircraft maintenance technicians who already have hands-on experience and now need to convert it into a licence, together with trainees working through an approved maintenance training course. The GCAA Ghana AME Exam study guide has 10 sections and about 2,989 words.
01Mathematics and Physics
Most marks in this domain come from fluent unit handling. Know the SI base units (metre, kilogram, second, ampere, kelvin, mole, candela) and the derived ones: newton (kg·m/s²), pascal (N/m²), joule (N·m), watt (J/s).
297 words, about 1 min02Electrical Fundamentals
Conventional current flows from positive to negative; electron flow is the opposite direction. Ohm's law V = IR and power P = VI = I²R = V²/R underpin nearly every question.
330 words, about 2 min03Electronic Fundamentals and Digital Techniques / Electronic Instrument Systems
Diodes conduct when forward biased (about 0.6–0.7 V for silicon) and block in reverse. Know half-wave, full-wave and bridge rectifiers, the transistor as a switch or amplifier, and the ideal op-amp (infinite open-loop gain and input impedance, zero output impedance).
327 words, about 2 min04Materials and Hardware
Separate ferrous (steels, corrosion-resistant steel) from non-ferrous (aluminium, magnesium, titanium, copper alloys). Know the aluminium alloys: 2024 (copper-bearing, good fatigue strength, poor corrosion resistance, often clad) versus 7075 (zinc-bearing, high strength) versus 6061.
277 words, about 1 min05Maintenance Practices
Read a micrometer from the sleeve (0.5 mm increments) plus the thimble (0.01 mm increments). A vernier calliper with 50 divisions on a 49 mm scale reads to 0.02 mm.
283 words, about 1 min06Basic Aerodynamics
Standard atmosphere at sea level: 15 °C, 1013.25 hPa, with a lapse rate of about 1.98 °C per 1 000 ft up to 36 090 ft, then isothermal. In steady level flight lift equals weight and thrust equals drag; any imbalance produces acceleration.
330 words, about 2 min07Human Factors
The SHELL model (Software, Hardware, Environment, Liveware) locates error at the interfaces between people and their workplace. Reason's Swiss-cheese model shows how latent organisational weaknesses line up with active errors to breach every defence.
285 words, about 1 min08Aviation Legislation
The 1944 Chicago Convention created ICAO, whose Annexes contain Standards and Recommended Practices that member states incorporate into national law. Know the key Annexes: Annex 1 Personnel Licensing, Annex 6 Operation of Aircraft, Annex 8 Airworthiness of Aircraft, Annex 14 Aerodromes, Annex 19 Safety Management.
299 words, about 1 min09Aeroplane Aerodynamics, Structures and Systems
Primary controls are ailerons (roll), elevators (pitch) and rudder (yaw); secondary controls include flaps, slats, spoilers and trim. Flaps increase lift and drag; spoilers dump lift and add drag.
279 words, about 1 min10Propulsion (Gas Turbine and Piston Engines)
The Brayton cycle: intake, compression, combustion at near-constant pressure, exhaust. Compressors (axial or centrifugal) raise pressure; the turbine extracts energy to drive the compressor, and the remaining energy either accelerates bypass air (turbofan) or drives a propeller (turboprop).
