The what is commercial pilot course typically takes around 18 to 24 months to complete. This timeframe includes both ground training and actual flying hours. During the ground phase you cover subjects such as meteorology navigation, aircraft systems air regulations and radio telephony. After the theory part is done you move to flying training where you put those concepts into real aircraft.
As part of the what is commercial pilot course one must complete a minimum of 200 flying hours according to regulatory norms.This includes day flying (basic manoeuvres take offs and landings) night flying cross country flying, instrument flying dual (with instructor) flights solo flights and simulator sessions. Because the flying component is time and weather dependent the schedule may vary a bit hence the 18-to-24month window.
Even though the standard duration is 18-24 months a few factors can make it shorter or longer. For example:
Flying weather & availability: Bad weather or aircraft downtime delays flying hours.
Student proficiency: If you grasp the theory quickly and fly well you may complete training faster.
Institute schedule & resources: Institutes with more aircraft and instructors may run smoother.
Regulatory clearances: Medical fitness license formalities exams may cause waits. Overall the what is commercial pilot course is structured to give you both a strong theoretical foundation and practical flying skill within roughly two years but you should plan for up to 24 months to allow for all components smoothly completing.
