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:
| Field | What to Record |
|---|---|
| Date | Date of the flight or lesson |
| Total flight time | Total duration of the flight or lesson |
| Departure and arrival | Location of departure and arrival (or location of lesson for simulator training) |
| Aircraft type and ID | Type and identification of aircraft, simulator, or training device |
| Safety pilot | Name of safety pilot, if required under 14 CFR 91.109 |
| Pilot experience type | Solo, PIC, SIC, or flight training received |
| Flight conditions | Day or night, actual or simulated instrument conditions, use of night vision goggles |
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-column AMC1 format.
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. The main §61.51(e) paths for logging PIC time include:
- 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, or you are a student pilot meeting the solo-flight conditions in §61.51(e)(4)
- You are acting as PIC of an aircraft that requires more than one pilot by type certification or regulation, subject to the certificate limits in §61.51(e)
- You perform PIC duties under an approved PIC-under-supervision program that meets §61.51(e)(1)(iv)
- You are an ATP acting as PIC in an operation requiring an ATP certificate
- 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 can equal PIC time, even if you’re not the acting pilot-in-command of that flight, as long as you are rated for the aircraft. In an operation where more than one pilot is required, the acting PIC may log PIC under one rule while another rated pilot logs PIC for the portion they flew as sole manipulator.
This is fundamentally different from EASA, which has no general “sole manipulator” PIC logging rule. 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 meet one of the §61.51(f) paths: for example, when you are qualified under the SIC requirements and occupy a crewmember station in an aircraft that requires more than one pilot by its type certificate, or when you hold the required category, class, and instrument rating if applicable and more than one pilot is required by the type certificate or the regulations under which the flight is conducted.
A key subtlety: §61.51 requires the name of a safety pilot when one is required under §91.109, and §61.51(f) allows SIC logging when more than one pilot is required by the regulations and the pilot meets the applicable rating requirements.
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)
Solo Time (61.51(d))
Solo time can only be logged when you are the sole occupant of the aircraft. If anyone else is on board, that time is not solo time under §61.51(d).
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 concepts. Only one person is acting as PIC for operational responsibility, but multiple people can log PIC time simultaneously if each meets a separate §61.51(e) logging path.
Example: A captain and first officer fly an aircraft that requires two pilots. The captain is acting PIC for the flight. The first officer is rated for the aircraft and hand-flies one hour as sole manipulator. During that hour, the captain may log PIC as the acting PIC of an aircraft requiring more than one pilot, and the first officer may log PIC as sole manipulator of an aircraft for which they are rated.
Under EASA, the same hand-flying hour would not automatically become PIC time. EASA has specific PIC logging cases, including designated PIC, solo, instructor/examiner time, SPIC, PICUS, successful checks with countersignature, and certain PIC-under-supervision cases. There is no general “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.
For a detailed comparison, see our guide on EASA pilot logbook requirements.
Electronic Logbooks: What the FAA Says
The Part 61 logbook text is format-neutral. It does not prescribe a paper logbook; it says required time must be documented and recorded in a manner acceptable to the Administrator.
Your electronic logbook needs to meet the same practical standard as a paper one: the records must be accurate, legible, and presentable when required. 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 still matter. If training time is involved, the entry needs the required instructor endorsement details from §61.51(h).
- 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, or to act as PIC of an aircraft certificated for more than one pilot flight crewmember, 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. Do not treat a generic “night” logbook entry as enough proof by itself. The entry needs to show that the required full-stop landings happened inside the §61.57(b) currency window. 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 no longer meet §61.57(c), you cannot act as PIC under IFR or in weather below VFR minimums until you regain currency. Once you have failed to meet the instrument experience requirements for more than six calendar months, you can reestablish instrument currency only through an instrument proficiency check (IPC).
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 under the sole-manipulator rule, but only if you meet the rating requirements in §61.51(e). Acting as PIC, operational responsibility, and logging PIC time are related concepts, not interchangeable labels.
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.
If a safety pilot is required under 14 CFR 91.109, §61.51 requires that safety pilot’s name in the logbook. SIC or PIC logging still depends on the §61.51(f) or §61.51(e) criteria being met, including the required ratings and whether more than one pilot is required by the regulations for that flight.
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), enter IMC for the approach segment, fly the ILS RWY 10R approach into Monterey solely by reference to instruments, and land at 17:50 local (00:50 UTC).
| Field | Entry |
|---|---|
| Date | 03/15/2026 |
| Aircraft | C182 N12345 |
| From | KSJC |
| To | KMRY |
| Total time | 0.8 |
| PIC | 0.8 |
| Instrument | 0.3 (actual) |
| Approaches | ILS RWY 10R KMRY |
| Landings | 1 (day) |
| Remarks | IFR flight plan, IMC on approach |
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 in actual instrument conditions. 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
- FAA PIC time has several logging paths. The sole-manipulator rule is the biggest difference from EASA, but it is not the only §61.51(e) basis for PIC time.
- “Logging PIC” and “acting as PIC” are separate concepts. Multiple pilots can log PIC simultaneously.
- Part 61 is format-neutral on logbooks, but records must be documented in a manner acceptable to the Administrator
- Currency entries need specifics. Approach types, landing counts, and night landing details must be specific enough to demonstrate compliance.
- Night passenger currency has its own window under §61.57(b): 1 hour after sunset to 1 hour before sunrise
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. Currency windows are calculated from actual solar data, 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.
