FAA Pilot Logbook Requirements: What You Actually Need to Log

You land after a beautiful VFR flight around the coast. No training, no checkride prep, no currency requirement to fulfill. Just flying for fun. You open your logbook and start writing.

But here’s the thing: the FAA doesn’t actually require you to log that flight.

Most pilots are surprised to learn this. We’re taught from day one to log everything, and most of us do. But the FAA’s logbook regulation is far more permissive than pilots assume. Understanding what’s actually required, and what’s just good practice, helps you keep a cleaner, more purposeful logbook.

What 14 CFR 61.51 Actually Requires

The FAA’s logbook regulation lives in 14 CFR 61.51, titled simply “Pilot logbooks.” The opening paragraph sets the tone for the entire regulation:

“Each person must document and record the following time in a manner acceptable to the Administrator: (1) Training and aeronautical experience used to meet the requirements for a certificate, rating, or flight review; (2) The aeronautical experience required for meeting the recent flight experience requirements of this part.”

Read that carefully. The FAA only mandates logging when you need to prove something: either that you’ve met the requirements for a certificate, rating, or flight review, or that you’re current under the recent experience rules of 14 CFR 61.57.

That’s it. There’s no blanket requirement to log every flight you ever make. A private pilot who completed training, holds no instrument rating, and flies with three passengers on a Sunday afternoon doesn’t technically need to log that flight, unless it contributes to a currency requirement like the 90-day landing rule.

Should you log everything anyway? Absolutely. Your logbook is your career record, your proof of experience, and your first line of defense in any FAA inquiry. But knowing the difference between “required” and “recommended” helps you understand what the regulation actually says versus what flight school tradition has taught you.

Required Logbook Entries

When you do log a flight, whether because it’s required or because it’s good practice, 14 CFR 61.51(b) spells out what each entry must contain:

Notice what’s not on this list: route of flight details beyond departure and arrival, the name of the PIC (unlike EASA), or the number of landings. The FAA’s required fields are surprisingly minimal compared to EASA’s 12 mandatory columns.

That said, logging additional detail (number of landings, approaches flown, specific maneuvers practiced) is smart practice. Your logbook entries for currency purposes need to be specific enough to demonstrate compliance, and an entry that says “3 landings” is far more useful than one that doesn’t mention landings at all.

Time Categories the FAA Recognizes

Under 14 CFR 61.51, the FAA breaks flight time into distinct categories. Each has its own logging rules and restrictions.

Pilot-in-Command Time (61.51(e))

This is where the FAA differs most dramatically from other authorities. You can log PIC time when:

• You are the sole manipulator of the controls of an aircraft for which you hold the appropriate category, class, and type rating (if required)
• You are the sole occupant of the aircraft
• You are acting as PIC of an aircraft that requires more than one pilot by type certification or regulation
• You are a flight instructor serving as the authorized instructor in a flight, provided you are rated to act as pilot in command of that aircraft

The first point is the big one. Under the FAA, sole manipulator equals PIC time, even if you’re not the designated pilot-in-command of that flight. This means a safety pilot and the pilot under the hood can both log PIC simultaneously. It means a first officer hand-flying the aircraft logs PIC time for that portion, even though the captain is the acting PIC.

This is fundamentally different from EASA, where PIC time is tied to who was designated as commander. If you fly under both systems, understanding this distinction is critical. More on that below.

Second-in-Command Time (61.51(f))

You can log SIC time when you are qualified under 14 CFR 61.55 and occupy a crewmember station in an aircraft that requires more than one pilot by its type certificate or by the regulations under which the flight is conducted.

A key subtlety: you can also log SIC time as a safety pilot when the other pilot is flying under simulated instrument conditions (hood or foggles). The safety pilot is a required crewmember under 14 CFR 91.109, which means they can log SIC, or PIC if designated as the acting pilot-in-command.

Instrument Time (61.51(g))

You log instrument time only when you operate the aircraft solely by reference to instruments under actual or simulated instrument flight conditions. For currency purposes under 61.57(c), you also need to record:

• The location and type of each instrument approach completed
• The name of the safety pilot (if under simulated conditions)

Autopilot use doesn’t disqualify instrument time. The FAA still considers this as the pilot manipulating the controls.

Solo Time (61.51(d))

Solo time can only be logged when you are the sole occupant of the aircraft. A student pilot on a supervised solo with a safety pilot in the other seat isn’t logging solo time. They’re logging PIC time (if sole manipulator) or training received.

Training Received (61.51(h))

When you receive training from an authorized instructor, the instructor must endorse the entry with a description of the training, the lesson length, and their signature, certificate number, and certificate expiration date (or recent experience end date). This isn’t optional. Unsigned training entries don’t count toward certificate requirements.

The FAA PIC Rule That Confuses Everyone

The sole manipulator rule under 14 CFR 61.51(e)(1)(i) is one of the most misunderstood provisions in aviation regulation, especially for pilots who also fly under EASA. Here’s how it works in practice.

Under FAA rules, “logging PIC” and “acting as PIC” are two separate legal concepts. Only one person can act as PIC at any given time. They’re the one responsible for the safe outcome of the flight under 14 CFR 91.3. But multiple people can log PIC time simultaneously if they each meet the criteria.

Example: You’re a private pilot rated in single-engine land. You’re flying right seat in a Cessna 172 while a friend (also rated) flies left seat as acting PIC. You take the controls for an hour. During that hour, you’re the sole manipulator of the controls in an aircraft for which you’re rated. You log PIC. Your friend, as the acting PIC, also logs PIC for the entire flight. Two pilots, both legally logging PIC, same airplane, same hour.

Under EASA, this would be impossible. EASA ties PIC time strictly to the designated commander of the flight. The co-pilot logs co-pilot time, period. There’s no “sole manipulator” concept.

If you hold both FAA and EASA licences, keep your logbooks consistent with each system’s rules. What counts as PIC under the FAA may not count under EASA, and mixing the two will create problems during licence validation or airline applications.

Electronic Logbooks: What the FAA Says

The FAA accepts electronic logbooks. There’s no regulation requiring a paper logbook, and no formal approval process for Part 61 pilots who want to go digital.

The relevant guidance comes from AC 120-78B (which replaced AC 120-78A in December 2024). The key point for private pilots: the use of electronic signatures and electronic recordkeeping under Parts 61, 63, 65, and 91 does not require formal FAA approval, acceptance, or authorization.

Your electronic logbook needs to meet the same standard as a paper one: the records must be accurate, legible, and presentable in a format acceptable to the Administrator. In practice, this means you should be able to produce a printed or PDF version of your logbook if an FAA inspector or examiner asks for it.

A few practical considerations:

• Backups matter. The FAA won’t accept “my app crashed” as an excuse for missing records. Choose a logbook that syncs to the cloud and allows data export.
• Instructor endorsements can be electronic. The FAA accepts digital signatures for training endorsements, so there’s no need for pen-on-paper if your logbook app supports it.
• Data portability is your responsibility. Make sure you can export your records in a standard format (CSV or PDF) so you’re never locked into a single platform.

Currency Requirements and Your Logbook

Your logbook isn’t just a historical record. It’s the primary proof that you’re current and legal to fly. Several FAA regulations tie pilot privileges directly to logbook entries.

90-Day Landing Currency (61.57(a))

To carry passengers, you need 3 takeoffs and 3 landings within the preceding 90 days in an aircraft of the same category, class, and type (if a type rating is required). For tailwheel aircraft, those landings must be to a full stop.

Night Passenger Currency (61.57(b))

To carry passengers at night, you need 3 takeoffs and 3 full-stop landings during the period from 1 hour after sunset to 1 hour before sunrise within the preceding 90 days. Note: the FAA defines “night” differently for currency than for logging. For logging purposes, night is the period from the end of evening civil twilight to the beginning of morning civil twilight. For currency, it’s the 1-hour-after-sunset rule. These are not the same timeframe. For more on how night time works, see our guide on how night time is actually calculated.

Instrument Currency (61.57(c))

To fly under IFR as PIC, within the preceding 6 calendar months you need:

• 6 instrument approaches
• Holding procedures
• Intercepting and tracking courses through the use of navigational electronic systems

If you let instrument currency lapse, you have an additional 6 months to complete these tasks. After that, you need an instrument proficiency check (IPC) from an authorized instructor or examiner.

Your logbook entries must be specific enough to demonstrate compliance. Generic entries like “1.5 hours IFR” aren’t sufficient. You need to record the type and location of each approach.

Flight Review (61.56)

Every 24 calendar months, you need a flight review consisting of at least 1 hour of flight training and 1 hour of ground training. Your instructor signs your logbook upon satisfactory completion. No signature, no flight review credit.

Common Mistakes Pilots Make

Not logging enough detail for currency

Your logbook entry for a night flight needs to show that you made full-stop landings during the currency window (1 hour after sunset to 1 hour before sunrise). An entry that just says “night” with no landing count or time specifics won’t hold up to scrutiny.

Confusing “logging PIC” with “acting as PIC”

These are different things. You can log PIC without being the acting PIC (sole manipulator rule). You can be the acting PIC without logging PIC (if you’re not rated in the aircraft). Getting these confused leads to inaccurate logbook entries and, in edge cases, regulatory violations.

Missing instructor endorsements

Training entries without a proper instructor endorsement (signature, certificate number, and certificate expiration date or recent experience end date) don’t count toward certificate requirements. If your instructor signed but forgot the certificate number, that entry is technically incomplete.

Not logging instrument approaches specifically

For IFR currency, “flew the ILS 28R at KSFO” is what the FAA wants to see. “Instrument approach” without the type and location doesn’t demonstrate compliance with 61.57(c).

Logging SIC in single-pilot aircraft

You can only log SIC time when more than one pilot is required, either by the aircraft’s type certificate or by the regulations under which the flight is conducted. Simply sitting in the right seat of a single-pilot airplane doesn’t qualify.

However, a safety pilot serving under 14 CFR 91.109 is a required crewmember, which means the regulations require more than one pilot for that flight. So a safety pilot in a Cessna 172 can log SIC time under 61.51(f)(2), or PIC time if designated as the acting pilot-in-command.

Rounding errors over time

The FAA doesn’t mandate a specific rounding method, but be consistent. If you round to the nearest tenth of an hour, do it every time. Mixing rounding methods creates discrepancies that accumulate over hundreds of entries.

A Practical Example

Here’s how a typical flight entry would look under FAA standards:

Scenario: You’re a private pilot with an instrument rating, flying a Cessna 182 (N12345) from San Jose (KSJC) to Monterey (KMRY) on March 15, 2026. You depart at 17:00 local (00:00 UTC), fly the ILS RWY 10R approach into Monterey, and land at 17:50 local (00:50 UTC). The flight is entirely in VMC but you request and fly the approach under IFR.

PIC time equals total time because you’re the sole manipulator in an aircraft for which you’re rated. Instrument time covers only the portion flown solely by reference to instruments (the approach segment under IFR). The approach is documented with type and location for currency purposes.

If this were a night flight, you’d also log night time and record whether the landing qualifies for night passenger currency under the 1-hour-after-sunset rule.

Key Takeaways

• The FAA only requires logging when you need to prove compliance with certificate, rating, flight review, or currency requirements, but logging every flight is strongly recommended
• Required entry fields are minimal: date, total time, locations, aircraft type and ID, safety pilot if applicable, and flight conditions
• PIC time under the FAA is based on sole manipulator of the controls, not who was designated as commander. This is a fundamental difference from EASA.
• “Logging PIC” and “acting as PIC” are separate concepts. Multiple pilots can log PIC simultaneously.
• Electronic logbooks require no FAA approval for Part 61 pilots, but records must be presentable in an acceptable format
• Currency entries need specifics. Approach types, landing counts, and night times must be detailed enough to demonstrate compliance.
• Night has two definitions under FAA rules: civil twilight for logging, and 1-hour-after-sunset for passenger currency

Keep Your FAA Logbook Accurate Without the Hassle

Tracking PIC versus SIC, logging the right approach details for IFR currency, splitting night time correctly, and making sure every entry has the fields the FAA expects. It adds up. And when you’re also flying under EASA or another authority, keeping two sets of rules straight gets even harder.

Skyden generates FAA-format PDF exports with all required fields structured correctly. Night time is calculated automatically using actual solar positions along your route, not the +30/-30 shortcut. Currency tracking shows you at a glance whether your landings, approaches, and flight reviews are current. And if you also fly under EASA, you can export in both formats from the same logbook.

Your hours are your credentials. The details should be right. Try Skyden free and see what an accurate logbook looks like.
