Can You Use a Calculator During the FAA Part 107 Exam?
Answering the critical question for aspiring drone pilots.
FAA Part 107 Exam Calculator Permissibility Checker
Select the type of calculator you plan to bring to the Airman Knowledge Test to see if it’s likely to be permitted. Final approval is always at the discretion of the test proctor.
This is the most important factor in determining if your device is allowed.
Allowed vs. Prohibited Device Features
What is the “can you use a calculator during faa part 107” Question About?
The question of whether you can use a calculator during the FAA Part 107 exam is a common and important one for anyone preparing to become a certified commercial drone pilot. The simple answer is **yes, you generally can**, but with significant restrictions. The FAA’s goal is to test your knowledge of aviation concepts, not your ability to perform complex math by hand. However, they must also ensure test integrity by prohibiting devices that can store information or formulas. This is why understanding the specific rules is critical before you walk into the testing center.
This topic isn’t about complex calculations, but about regulatory compliance. The “calculator” is a tool to help with questions that might involve basic arithmetic, such as calculating runway lengths, load factors, or interpreting performance charts from the Airman Knowledge Testing Supplement provided during the exam.
The Formula for Calculator Approval
There isn’t a mathematical formula, but rather a logical one based on FAA guidelines (specifically AC 60-11C) and testing center policies. The core principle for determining if your device is allowed can be broken down into a few key variables.
| Variable | Meaning | Permitted State (Unit) | Typical Range |
|---|---|---|---|
| Functionality | The types of calculations the device can perform. | Basic (Arithmetic) | Add, Subtract, Multiply, Divide. Basic square root or percent keys are often fine. |
| Programmability | The ability to store, record, or execute programs or custom formulas. | None (Not Programmable) | Devices like TI-83/84/89 or other graphing calculators are typically prohibited. |
| Memory | The ability to store data or notes. | No Permanent Memory / Erasable | Any device with memory must have a clear way to show the proctor it has been erased. |
| Primary Device | The form factor of the calculator. | Dedicated Device | Phones, tablets, and smartwatches are strictly forbidden. |
Practical Examples
Let’s look at a few common scenarios to see how the rules apply.
Example 1: The Basic Scientific Calculator
- Input: A pilot brings a simple, non-programmable scientific calculator (e.g., Casio FX-260 or TI-30Xa).
- Analysis: This device has no programming capabilities and no text storage. Its functions are for direct calculation.
- Result: **Permitted**. This is the safest and most recommended type of calculator to bring.
Example 2: The Advanced Graphing Calculator
- Input: A student brings their Texas Instruments TI-84 Plus graphing calculator from college.
- Analysis: This device can store extensive notes, run programs, and has advanced graphing features. It’s impossible for a proctor to verify all memory is cleared.
- Result: **Prohibited**. Devices with permanent or non-verifiable memory are not allowed.
Example 3: The Digital E6B Flight Computer
- Input: An aspiring pilot brings an ASA CX-3 or Sporty’s Electronic E6B.
- Analysis: These are “aviation-oriented calculating devices” and are generally allowed. However, they have memory functions.
- Result: **Conditionally Permitted**. You will be required to demonstrate to the test proctor that the device’s memory has been fully erased before starting the test. Be sure you know how to do this. For more information, check out our guide on FAA Part 107 calculator rules.
How to Use This Calculator Permissibility Checker
Our tool simplifies the official rules into a quick and easy check. Here’s how to use it:
- Select Your Calculator Type: From the dropdown menu, choose the category that best describes the device you intend to bring to the exam.
- Review the Result: The tool will instantly display one of three statuses:
- PERMITTED: Your device is very likely to be allowed.
- CONDITIONAL: Your device may be allowed, but you must take specific actions (like clearing the memory).
- PROHIBITED: Your device is not allowed in the testing center.
- Read the Explanation: Each result comes with a detailed explanation of *why* the device is or is not allowed, based on official FAA guidance. Understanding the reasoning is as important as the result itself. You might want to learn more about the Part 107 exam allowed items.
Key Factors That Affect Calculator Approval
Several factors can influence the final decision on test day. Being aware of them can prevent surprises.
- Proctor Discretion
- The test proctor has the final say on any and all materials brought into the testing room. Their decision is binding. If they are unable to verify your calculator meets the requirements, they can deny its use.
- Device Memory and Erasure
- The most critical factor is memory. Calculators that can store pre-written programs, formulas, or notes are prohibited. If your device (like an E6B) has memory, you must be able to prove to the proctor that it has been cleared.
- Testing Center Policy
- While guided by the FAA, individual testing centers (like those run by PSI) may have their own specific procedures. Some may provide a basic calculator on-site to avoid any issues. In fact, the testing computer itself has a basic, 4-function on-screen calculator available.
- The “Aviation-Oriented” Clause
- FAA documentation specifically permits “aviation-oriented calculating devices,” which includes both analog and digital E6B flight computers. This is a specific exception to the general “basic calculator” rule. Explore our resources on using an E6B calculator for the Part 107 test.
- Physical vs. App-Based
- No device that is also a communication device is allowed. This strictly prohibits the use of calculator apps on smartphones, tablets, or smart watches.
- Appearance of Complexity
- Even if your calculator is non-programmable, if it has a large screen, many complex function buttons, or looks like a computer, it may draw extra scrutiny from the proctor. When in doubt, simpler is better. More details can be found in the official FAA knowledge test calculator policy.
Frequently Asked Questions (FAQ)
Can I use my iPhone calculator on the Part 107 test?
No. Absolutely not. All personal electronic devices, especially smartphones, are strictly prohibited in the testing room.
What if my calculator has memory but I promise not to use it?
This will not be accepted. The rule is not about intent; it is about capability. If a device has prohibited capabilities (like storing notes or programs), it is not allowed, unless the memory can be demonstrably cleared for the proctor.
Will the testing center provide a calculator?
Many testing centers will provide a basic 4-function calculator or you can use the simple one built into the testing software. It’s a good idea to call your specific testing center ahead of time to confirm.
Is an E6B flight computer (the round, slide-rule type) allowed?
Yes, the classic analog E6B is explicitly allowed as a “navigation computer” and is a great tool to bring. It requires no batteries and has no electronic memory, so it faces no scrutiny.
Do I really even need a calculator for the Part 107 exam?
While many questions don’t require one, some might involve basic calculations for performance, loading, or chart interpretation. Having a basic calculator can save time and reduce the chance of simple arithmetic errors under pressure.
Can I bring a scientific calculator?
A non-programmable scientific calculator is generally allowed. These are useful as they have parentheses and can handle order of operations correctly. The key is that it cannot store text or be programmable.
What is the difference between a programmable and non-programmable calculator?
A non-programmable calculator can only perform the functions printed on its keys. A programmable calculator allows you to write, store, and execute multi-step programs or custom formulas, which is why they are banned. Check out our guide on choosing a drone pilot exam calculator for more info.
What happens if I bring a prohibited calculator?
You will be told to store it outside the testing room (e.g., in your car or a locker). You will not be allowed to use it. You will likely be offered a basic calculator by the testing center or have to rely on the on-screen version.
