Ground classes of Technical General for CHPL at Captessar Aviation again covers most relevant topics as per DGCA prescribed syllabus in which we cover Piston engine, Turbine engine, Principle of flight, electricity and aircraft and systems. I this is the toughest paper of CPL exams with lengthy syllabus. So the duration required for this paper at our academy is 35 days. This paper is required for CHPL but not required for CHPL conversion.

Captessar Aviation use video classes, Computer based training, conduct practice tests, mock tests, and mock interviews to help candidates crack DGCA or Airlines entrance exams.
