DGCA CPL Technical General study guide
DGCA CPL Technical General · Work through your exam, one topic at a time.
The DGCA CPL Technical General paper is one of the written ground examinations a candidate must clear on the route to a Commercial Pilot Licence issued by the Directorate General of Civil Aviation, India. It is a technical, aircraft-systems paper rather than a regulations or meteorology paper: it tests whether the candidate actually understands how the aeroplane is built and how its systems behave, which is the knowledge a commercial pilot is expected to carry into the cockpit and into dealings with maintenance and dispatch. The DGCA CPL Technical General study guide has 5 sections and about 1,847 words.
01Airframes, Structures and Aircraft Systems
This domain tests how the primary structure carries and transmits load, and how the major systems - hydraulic, pneumatic, fuel, pressurization and ice protection - generate, distribute and control power. Questions often ask you to identify load paths, system components, normal indications and the effect of a failure.
361 words, about 2 min02Aircraft Engines and Propellers
This domain tests reciprocating-engine cycles and components, turbine-engine sections and parameters, and propeller pitch control and efficiency. Expect questions on ignition, carburetion, cooling, turbocharging, engine indications and the forces produced by a propeller.
355 words, about 2 min03Aircraft Instruments
This domain tests pitot-static instruments, gyroscopic flight instruments, magnetic compass behaviour and the engine and system indications used in normal and abnormal operation. Questions often require you to predict an indication after a blockage, a setting change or a failure.
375 words, about 2 min04Aircraft Electrical and Electronics Systems
This domain tests DC and AC power generation, distribution and protection, battery and bus behaviour, bonding, and the electronic systems used for communication, navigation and indication. Questions often involve current, voltage drop, circuit protection and the difference between generator and alternator construction.
351 words, about 2 min05Aircraft Materials, Hardware and Maintenance Practices
This domain tests aircraft alloys and their heat treatment, corrosion and non-destructive testing, standard hardware and locking, and the maintenance controls that keep an aircraft airworthy. Expect questions on identifying a material, selecting a fastener and understanding mandatory versus advisory documents.
