DGCA CPL Tech Specific study guide
DGCA CPL Tech Specific · Work through your exam, one topic at a time.
The DGCA CPL Technical Specific paper is one of the knowledge examinations a candidate must clear on the path to an Indian Commercial Pilot Licence, alongside the Air Regulations, Meteorology and other papers set by the Directorate General of Civil Aviation. It is aimed at student pilots who have completed or are close to completing flight training at an approved Flying Training Organisation and are ready to sit the technical ground examinations through the DGCA examination portal. The DGCA CPL Tech Specific study guide has 5 sections and about 1,595 words.
01Aircraft - Technical Specific (airframe, systems and powerplant)
DGCA CPL Technical Specific questions probe whether you understand how the airframe carries load and how systems fail, not just component names. Expect semi-monocoque structures, landing gear, hydraulics, fuel, pressurisation, ice protection and reciprocating/turbine powerplants.
347 words, about 2 min02Flight performance, planning and loading
The exam tests whether you can move between chart, calculation and regulatory limit: V-speeds, density altitude, take-off/landing distance, climb, fuel reserves, and the weight-and-balance envelope. V-speeds: Vne never exceed; Vno normal operating; Va manoeuvring (decreases with weight); Vfe flap extend; Vle gear extend; Vx best angle; Vy best rate; Vmc minimum control speed (multi-engine).
326 words, about 2 min03Aircraft instruments
The questions test the pitot-static and gyro systems, their errors, and how to interpret readings when a source is blocked or a setting is wrong. The ASI uses pitot (total) pressure and static pressure; it indicates dynamic pressure, so it is calibrated to TAS only at sea level and standard density.
353 words, about 2 min04Air navigation (technical aspects)
This domain tests the calculations behind navigation: Earth geometry, magnetism, the wind triangle, radio aids and chart projections. A great circle is the shortest path; a rhumb line is a constant track.
294 words, about 1 min05Radio telephony and communications equipment
The exam checks frequency bands, equipment operation, standard phraseology and emergency procedures - the practical detail that prevents a frequency or readback error. VHF airband is 118.000–136.975 MHz; 8.33 kHz channel spacing is standard in high-density airspace.
