Commercial Pilot License (CPL)
Ground School - Theory Classes

Overview

The Commercial Pilot License (CPL) is a professional qualification that permits the holder to act as a pilot of an aircraft and be paid for their work. Before taking to the skies commercially, every aspiring pilot must undergo comprehensive Ground School training, covering 9 core theoretical subjects as prescribed by the Directorate General of Civil Aviation (DGCA), India.

CPL Ground School forms the academic backbone of a commercial pilot’s training, ensuring a thorough understanding of aviation rules, aircraft systems, meteorology, navigation, and safety protocols.

What You’ll Learn in CPL Ground School

Air Regulations

Objective:

Learn the laws governing aviation and flight operations in Indian and international airspace.

Topics Covered:

  • ICAO & DGCA roles and responsibilities
  • Civil Aviation Requirements (CARs)
  • Licensing, logbooks, and pilot responsibilities
  • Classification of airspaces (A to G)
  • VFR, IFR, and ATC clearance procedures
  • Rules of the Air, collision avoidance
  • Wake turbulence and separation minima
  • Emergency procedures and communication protocols

Air Navigation

Objective:

Master navigational techniques for accurate route planning, execution, and safety assurance.

Topics Covered:

  • Dead reckoning and pilotage
  • Radio navigation aids (VOR, ADF, DME, GPS, INS)
  • Airspace structure, routes, and charts (Jeppesen, ICAO)
  • Time calculations (UTC, LMT)
  • Compass errors, variation & deviation
  • RNAV and GNSS procedures
  • Use of flight computers (E6B or CRP-5)
  • Position fixing and diversions
  • PBN (Performance Based Navigation) concepts

Avation Meteorology

Objective:

Understand weather patterns and apply meteorological knowledge to flight planning and in-flight decision-making.

Topics Covered:

  • Atmospheric structure and pressure systems
  • Clouds, precipitation, and visibility
  • Wind shear, turbulence, icing, and fog
  • Thunderstorms, jet streams, and frontal systems
  • Weather charts, METARs, TAFs, and SIGMETs
  • Climatology and seasonal variations
  • QNH/QFE settings and altimetry
