The Commercial written is the point where the FAA starts asking a different kind of question. Not just can you fly the aircraft, but can you operate it for hire — legally, within limits, with someone else's money and safety involved. Performance charts, commercial privileges and limitations, weight and balance done properly.

AirTest Pro covers the commercial bank with the same question-by-question explanations and FAA references as the rest of the path, with particular weight on the areas that catch experienced pilots off guard: the regulations around compensation, the aircraft performance math, and the aerodynamics questions that private students were allowed to gloss over.

By the commercial written, “I've been flying for years” stops being an advantage. The regulations don't care about your logbook.

The trap at this level is confidence. Pilots arriving with a few hundred hours often skim the material and score in the low eighties — enough to pass, not enough to hold up in a job interview or a Part 135 checkride. The material here is worth learning properly the first time.

Built for working pilots

You're studying between paid flights and a job hunt. The course is shaped around that:

  • Commercial privileges, limitations and compensation rules, explained in plain language.
  • Performance and weight-and-balance problems worked out, not just answered.
  • Certified instructors available when a regulation reads two ways.
