Section 107.73 Initial and recurrent knowledge test. (2019)


Are you interested in the Part 107 initial or recurrent knowledge test?

In this article we will discuss (1) the Part 107 initial knowledge test, (2) the Part 107 recurrent knowledge test, (3) the differences between both tests, (4) practice Part 107 initial and recurrent knowledge test, (5) actual language from 107.73, and (6) the FAA’s commentary on knowledge tests from the preamble to the Small Unmanned Aircraft Rule.

This article on the initial and recurrent knowledge test is part of an overall set of articles on each of the Part 107 drone regulations. Use these links below for navigation between the regulation pages.

Part 107 Initial Knowledge Test

If you want to fly commercial in the United States, you’ll most likely be flying under Part 107 which requires a remote pilot certificate. To obtain for the first time a remote pilot certificate, you’ll need to take and pass a Part 107 initial knowledge test. If you are a current Part 61 certificated manned pilot, you have an option of going another method. See my step-by-step instructions page on how to obtain your remote pilot certificate.

The Part 107 initial knowledge test contains 60 questions and you have 120 minutes to take it. The subject areas on the exam are: (1) regulations, (2) airspace, (3) weather, (4) loading and performance, and (5) operations. You’ll need to pass the exam with a score of 70% or higher.

Part 107 Recurrent Knowledge Test

Individuals who have obtained their remote pilot certificates have to maintain their aeronautical knowledge currency by doing 1 of 3 methods. Section 107.65 says, a “person may not operate a small unmanned aircraft system unless that person has completed one of the following, within the previous 24 calendar months:

(a) Passed an initial aeronautical knowledge test covering the areas of knowledge specified in §107.73(a);

(b) Passed a recurrent aeronautical knowledge test covering the areas of knowledge specified in §107.73(b); or

(c) If a person holds a pilot certificate (other than a student pilot certificate) issued under part 61 of this chapter and meets the flight review requirements specified in §61.56, passed either an initial or recurrent training course covering the areas of knowledge specified in §107.74(a) or (b) in a manner acceptable to the Administrator.”

One of the methods is to take the Part 107 recurrent knowledge test. This article is focused specifically on the initial and recurrent knowledge test. I have addressed elsewhere other issues like:

The recurrent knowledge test consists of 40 questions. You have 1.5 hours to take the exam. The subject areas consist of regulations, airspace, and operations.

Differences Between the Initial & Recurrent Knowledge Test

The initial has 60 questions while the recurrent knowledge test has 40 questions.

The initial gives you 120 minutes while the recurrent knowledge test is 80 minutes.

Since the number of questions decreased and also the number of subjects tested with the recurrent knowledge test, this might cause confusion as to how to spend your time studying. There are two ways at looking at how you should focus your time: (1) comparing using the airmen certification standards and (2) using the actual subject areas of the regulations.

Comparison Using the Airmen Certification Standards (ACS)

Here is a table I created comparing the initial to the recurrent knowledge test using the ACS.

Please note that while Area I and Area II are being tested completely, in the recurrent knowledge exam, tasks  A. Radio Communications Procedures and E. Physiology are not tested so it’s really not ALL of Area V.

Comparison Using the Regulations

Another way of determining how to spend your time studying is looking at what the FAA really wants you to know based upon what the regulations specifically list. Section 107.73 and 107.74 list out specific areas.

Remember that the current manned pilots aircraft pilots have another way of getting current. They can take the online training courses. I took the topics from the initial and recurrent knowledge test and the topics from the initial and recurrent online training course and compared them in a table below.


initial versus recurrent remote pilot (aka drone license) test

The FAA is really emphasizing the first 4 subjects. You should know those areas like the back of your hand.

The 5th, 6th, and 7th lines also give you a clue that you MUST know that if you are going for an initial or recurrent knowledge test.
