A Part 135 pilot operating as SIC under an approved Pilot Development Program raises a question that sits at the intersection of two distinct FAA regulatory concepts that pilots and operators frequently conflate: acting as pilot-in-command and logging pilot-in-command flight time. These are not the same thing, and the distinction has direct consequences for how time accumulates toward certificate and hiring minimums.
Under 14 CFR 61.51(e)(1)(i), a certificated pilot may log PIC time whenever that pilot is the sole manipulator of the controls of an aircraft for which the pilot holds the appropriate category and class rating. Critically, this provision does not require the pilot to be designated as the acting PIC — it requires only that they be rated for the aircraft and manipulating the controls. Because the Caravan does not require a type rating, a commercial pilot holding a single-engine land or appropriate category/class rating is "rated" for that aircraft in the regulatory sense. This means that during any flight segment — including empty legs — where the SIC is the sole manipulator of the controls, PIC time is legally loggable under 61.51(e)(1)(i), regardless of whether they hold the acting PIC designation for that flight. The FAA has affirmed this interpretation through multiple legal counsel opinions over the years, and it remains one of the more consistently misunderstood distinctions in general aviation currency discussions.
The A062 OpSpec authorization adds a layer of nuance worth understanding. Under a PDP program, the operator has received FAA authorization to conduct what would otherwise be single-pilot operations with two crew members, typically for training and mentoring purposes. The presence of a second pilot in a single-pilot aircraft does not by itself create a two-pilot regulatory requirement for the purposes of 61.51(e) — the aircraft's certification still does not require a second pilot. What this means practically is that the SIC in this scenario occupies an unusual position: they are not logging SIC time because the operation requires two pilots by regulation or type certificate, but rather because the operator's approved program creates that operational requirement. Their ability to log PIC as sole manipulator is therefore not diminished by the SIC role itself.
The pilot's underlying concern — accumulating sufficient PIC time to qualify for 121 carriers — reflects a broader structural tension currently visible across the regional and charter sectors. Operators using PDP programs have benefited from a cost-effective way to develop pilots while providing mentored line experience, but the program's design can leave SICs in a holding pattern when captain seats are unavailable. With mainline carriers offering improved pay and quality-of-life packages, regional captain attrition has slowed considerably in recent cycles, compressing the upgrade pipelines that PDP pilots depend on. SICs who have reached R-ATP minimums but cannot secure an upgrade are increasingly evaluating lateral moves, and the question of loggable PIC time is central to that calculus because 121 carriers and many 135 operators with turbine equipment scrutinize PIC hours as an indicator of experience depth, not merely total time.
For pilots navigating this specific situation, the practical advice from regulatory guidance is consistent: document the time carefully, annotate logbook entries to reflect sole manipulator status, and ensure that the aircraft category and class rating is current and appropriate for the aircraft being flown. Pilots should also consider requesting written guidance from their Director of Operations or chief pilot regarding how the company interprets PIC logging within the PDP structure, since some operators incorrectly restrict SIC pilots from logging any PIC time even when legally entitled to do so. Given the significant career implications of PIC time accumulation at this stage, consulting with an aviation attorney familiar with FAR Part 61 interpretations is a prudent investment before relying solely on informal advice, however well-intentioned.
