Few topics create more debate among airline and charter pilots than logging PIC time during Initial Operating Experience, better known as IOE. Sit in any crew room long enough and eventually someone will ask the question: can you legally log PIC time while on PIC IOE in Part 121 or Part 135 operations?
The answer often surprises pilots. In many cases, yes — the FAA may allow a pilot to log PIC time during supervised PIC IOE, even when another qualified pilot is acting as the operational pilot in command.
Why This Question Confuses So Many Pilots
The confusion comes from one major misunderstanding: acting as PIC and logging PIC time are not always the same thing. During PIC IOE, a check airman or training captain may be the acting PIC for operational purposes, but the upgrading pilot may still be performing the duties of pilot in command.
That distinction is exactly where 14 CFR §61.51 becomes important.
The FAA Rule Behind Supervised PIC Time
Under 14 CFR §61.51(e)(1)(iv), a pilot may log PIC time when the pilot performs the duties of pilot in command while under the supervision of a qualified pilot in command, provided the pilot is rated for the aircraft and is undergoing an approved PIC training program.
The key phrase is not “acting as pilot in command.” The key phrase is “performs the duties of pilot in command.”
That wording matters. It means FAA logging rules recognize that a pilot in approved PIC training may be functioning as captain under supervision before being released to operate independently.
What PIC IOE Really Is
PIC IOE is not just another training event. It is the bridge between being qualified in training and being trusted in real-world line operations. The pilot is no longer simply learning procedures in a simulator. The pilot is now managing actual flights, real passengers, operational pressures, weather, dispatch coordination, crew decisions, fuel planning, delays, and abnormal situations.
In other words, the pilot is learning how to command the operation.
That is why supervised PIC logging exists. The FAA understands that command judgment develops under supervision before a pilot is released as a line captain.
When Logging PIC During IOE May Be Legal
Logging PIC time during Part 121 or Part 135 PIC IOE may be appropriate when the pilot is already properly rated, is enrolled in an approved PIC training program, and is actually performing PIC duties under the supervision of a qualified PIC.
This commonly applies to captain upgrade IOE, supervised captain operating experience, or approved PIC transition training.
It generally does not apply to SIC IOE, new-hire first officer training, or situations where the pilot is not in an approved PIC training program.
Why This Matters for Your Logbook
Turbine PIC time is one of the most valuable categories in a professional pilot’s logbook. It can affect airline hiring, upgrade opportunities, insurance minimums, corporate aviation requirements, and interview competitiveness.
But PIC time must be defensible. Logging PIC time incorrectly can raise serious questions during interviews, background checks, PRIA reviews, or airline application audits.
At the same time, many pilots fail to log legal PIC time because they rely on crew room opinions instead of the actual regulation.
The Bottom Line
A pilot may be able to legally log PIC time during PIC IOE in Part 121 or Part 135 operations if the pilot is properly rated, is undergoing an approved PIC training program, and is performing PIC duties under the supervision of a qualified pilot in command.
The important distinction is simple: the check airman may be acting as PIC, while the upgrading pilot may still be logging PIC under FAA supervised PIC rules.
Understanding that difference can protect your logbook, strengthen your career record, and help you avoid one of the most common misconceptions in professional aviation.
