Pilot in Command Under Supervision (PICUS)

PICUS is a regulated logging category within the EASA pilot license system, defined in the interpretation provisions of FCL.010 and elaborated in the Acceptable Means of Compliance (AMC1 FCL.010) and Guidance Material (GM1 FCL.010) issued by EASA. Under these provisions, PICUS is time during which a pilot — who holds the applicable license and type or class rating for the aircraft — is operating as PIC for the purposes of flight conduct while a second, more senior pilot holds the legal command authority for the flight. The PICUS pilot manages the operation: makes airmanship decisions, manages the workload, flies the profiles, and conducts the crew management functions of the captain's seat. The supervising captain monitors, is available to intervene if required, but does not exercise active control or direct the PICUS pilot's actions except in safety-critical situations requiring intervention.

The credit mechanism under FCL.510(a)(2) is specific: of the 1,500 total flight hours required for ATPL(A) issue, at least 500 hours must be on multi-pilot aircraft and at least 500 hours must be as PIC, but the regulations permit up to 500 of those PIC hours to be satisfied by PICUS time. This means a First Officer who accumulated 500 hours of PICUS during airline line training before logging 1,000 hours of non-PICUS PIC time has met the 1,500-hour total and the 500-hour PIC minimum — the ATPL can be issued. The PICUS credit is a significant accelerant for airline First Officers in the transition from frozen ATPL to full ATPL: without PICUS, a First Officer would need to accumulate 500 hours of actual PIC (captain command) time, which may require a command upgrade and is not structurally possible during the First Officer phase of a career.

PICUS time is logged in a dedicated PICUS column in the EASA standard logbook (AMC1 FCL.050 logbook structure). The entry discipline is as follows: the PICUS pilot logs the flight time in the PICUS column and also carries the total in the PIC column (because PICUS counts as PIC for ATPL experience purposes). The supervising captain logs the same flight time in their own P1 (PIC) column — both pilots log the time as PIC simultaneously, which is the only situation in EASA logbook keeping where two pilots log the same flight as PIC for their own record. This dual-PIC logging is not an error; it reflects the regulatory structure in which both the PICUS pilot (for experience credit purposes) and the supervising captain (for actual command authority purposes) have a legitimate PIC claim on the same flight.

PICUS is structurally distinct from SPIC (Student Pilot in Command). SPIC applies to student pilots before licence issue, typically in single-pilot aircraft, when an instructor is on board in observation mode. SPIC time credits toward the PIC requirement for CPL issue (FCL.310) and cross-country PIC time for IR (FCL.620). PICUS applies to license-holding pilots in multi-pilot operations, crediting toward ATPL issue (FCL.510(a)). The regulatory treatment is different: SPIC is a pre-license logging convention; PICUS is a post-license, post-type-rating experience-crediting mechanism. Confusing the two produces logbook errors that create problems at ATPL issue review.

PICUS is typically logged during Line Training — the structured program of supervised line flights that a newly type-rated First Officer completes before being authorized for unsupervised line operations. Line Training programs under Part-ORO ORO.FC.220 typically require between 100 and 200 supervised sectors before line check clearance, with the Line Training Captain (LTC) or Type Rating Examiner acting as the supervising captain in the jump seat or right seat. Not all of these sectors are necessarily PICUS — the LTC makes the designation based on the First Officer's demonstrated competency and the operational conditions of each flight. A challenging IFR departure or complex approach may be conducted as crew-coordinated dual operation rather than PICUS; a straightforward sector in good VMC may afford the First Officer full PICUS status.

The FAA system has no formally defined PICUS logging term. The concept of supervised PIC time is recognized in FAA ATP and airline operations — FAA Interpretation letters and the ATP Certification Training Programme (ATP-CTP) context acknowledge that airline line training involves supervision — but there is no FAA-equivalent logbook column or explicit hour-credit mechanism equivalent to EASA's 500-hour PICUS-toward-ATPL structure. US airline First Officers log SIC time (Second in Command, §61.51(f)) during line operations under normal conditions, and may log PIC time only when they are the sole manipulator of the controls and the flight does not require a type rating, or when they hold the type rating and are designated as PIC for the flight — neither of which produces a PICUS-style supervised-PIC accumulation toward ATP minimums.

PICUS tracking is a practical pain point at airlines and ATOs managing First Officer development towards ATPL. The PICUS designation requires a per-sector judgment by the supervising Line Training Captain, creating a documentation dependency: at the end of each PICUS-designated sector, the LTC must confirm the PICUS status in the training record, and the First Officer must log the time in the PICUS column with the LTC's name as supervisor. Where line training records and pilot logbooks are maintained separately — the airline in its crew management system, the pilot in a personal logbook — discrepancies arise. A First Officer who loses their personal logbook or has it damaged loses the PICUS evidence; the airline's crew management system may not separately record whether each sector was PICUS-designated or regular dual crew.

The 500-hour PICUS credit is also time-sensitive in the context of the 7-year theoretical knowledge validity clock running from ATPL examination passes. A frozen ATPL cadet who passes the ATPL theory examinations and then accumulates hours slowly — due to airline hiring pauses or route reductions — may find the theoretical knowledge validity expiring before the 1,500 total hours are reached. PICUS time during line training is one of the most efficient ways to accumulate PIC hours that bring the ATPL issuance milestone closer within the theoretical knowledge validity window.

Aviatize's training management module captures PICUS designation at the sector or flight level during line training documentation. When a Line Training Captain completes a post-flight training report for a supervised sector, the interface includes a clear PICUS designation field that records whether the sector qualified as PICUS, with the LTC's digital signature confirming the designation. This creates an authoritative primary record of PICUS-designated time that exists independently of the First Officer's personal logbook — a training record that can be produced at ATPL application to verify PICUS claims that exceed or differ from what appears in the personal logbook.

For frozen ATPL progress tracking, the compliance and auditing module maintains a running counter of each First Officer's PICUS hours, total PIC hours (PICUS + non-PICUS), and remaining hours to ATPL minimums across all required columns simultaneously. The dashboard view shows at a glance whether a cadet is on track to reach the 1,500-hour total and 500-hour PIC minimum within the theoretical knowledge validity window, flagging candidates whose hour accumulation rate implies a risk of theory expiry before ATPL issuance. This enables proactive conversations between the airline's training department and the cadet about career trajectory, route allocation, and the urgency of command applications — well before the 7-year clock becomes a real constraint.
