Percival Pembroke

Prince development boundary

Use the documented longer-wing, increased-weight development from the Prince as a family distinction, while requiring authoritative identification. [RAF Museum](https://www.rafmuseum.org.uk/research/collections/hunting-percival-pembroke-c1/)

1. Which documentary designation establishes that the candidate is a Pembroke rather than a Prince or Sea Prince? definition
2. Which drawing or specification establishes the relevant wing and weight differences? boundary

Serial and variant corroboration

Require agreement between construction identity, recorded variant and service or registration history; keep markings as separately assessed evidence.

1. Which manufacturer or operator record links this construction number to a Pembroke variant? provenance
2. Do current markings represent this aircraft's identity, a former identity or a display interpretation? boundary

Passenger layout evidence

Record seat orientation, installed places and restraint evidence without treating one preserved cabin as the type-wide standard.

1. Which approved layout establishes the seat count, orientation and restraint arrangement for this configuration? provenance
2. What passenger and baggage loading limits apply to that layout? measurement

Training and photographic fit

The type supported pilot-training, classroom and photographic roles; record the installation actually evidenced for a variant or example. [RAF Museum](https://www.rafmuseum.org.uk/research/collections/hunting-percival-pembroke-c1/)

1. What records establish dual controls, classroom stations or photographic equipment for the configuration being modelled? provenance
2. Which structural alterations, electrical demands and mass changes accompany that installation? boundary

Engine and propeller record

Treat component models, approved combinations, servicing requirements and limitations as facts to establish from applicable technical records.

1. Which engine and propeller models are documented for this Pembroke variant and modification state? definition
2. Which approved instructions specify fuel, lubricant and operating limits for the installed combination? provenance

Configuration-specific system states

Identify how the applicable Pembroke manual describes flight controls, landing gear, flaps, fuel selection and warning indications, including any training-control differences.

1. Which cockpit indications and physical checks establish the documented state of these systems? definition
2. Which interlocks or warnings are documented, and which would otherwise be unsupported assumptions? boundary
3. What configuration-specific instructions must qualified personnel consult before a ground function check? action

Configuration mass and balance

Record authoritative dimensions and mass-and-balance data, including the effects of seating, role equipment and subsequent alterations.

1. What dimensions and maximum permitted masses are documented for the selected variant? measurement
2. Which weighing report and equipment schedule establish the example's current empty mass and centre of gravity? provenance

Conditional performance

Require configuration, mass and environmental conditions alongside speed, range, climb and runway-performance information.

1. Which manual revision supplies performance data for this variant and installed equipment? provenance
2. What mass, atmospheric, runway and engine-operating assumptions accompany each value? measurement
3. Which missing inputs prevent an agent from supporting a proposed loading or movement assessment? action

Life-extension evidence

The RAF Museum reports fatigue-life extension modifications in 1970; applicability, embodiment and remaining life must be established separately for each example. [RAF Museum](https://www.rafmuseum.org.uk/research/collections/hunting-percival-pembroke-c1/)

1. Which modification instructions identify affected Pembroke variants, serials and structural areas? provenance
2. What records demonstrate embodiment and subsequent inspection compliance? provenance
3. Which missing usage or maintenance records leave structural-life assessment unresolved? boundary

Action-specific evidence

Assess display access, towing, ground running and flight separately, accounting for removed equipment, preservation treatments and restoration changes.

1. Which recorded alterations or preservation measures affect the proposed action on this Pembroke? boundary
2. What current inspection, technical instructions and responsible-person authorisation support that action? action
3. If flight is proposed, which jurisdiction and current aircraft-specific approval documents govern it? provenance
