How GCBA standards are developed.

A professional standard is only as credible as the process that produced it. When rules are written behind closed doors, the people they affect have no way to test the reasoning, surface overlooked cases or hold the drafters to account. The GCBA method treats every material choice — inclusions, exclusions, thresholds, evidence expectations — as a decision that must be defensible in public.

That commitment shapes the timeline. Drafting is slower than a private ruleset because each iteration is designed to withstand external comment. It is also more durable: standards that survive consultation tend to survive contact with the market.

A drafting group is convened by the Advisory Board for each standard. It combines practising brokers, operator representatives where relevant, aviation counsel and, on technology-facing standards, independent specialists. The group produces the draft; the Board decides. Separating drafting from adoption is deliberate: it prevents any single working group from becoming an unaccountable rule-writer.

Members of drafting groups declare interests before appointment. Conflicts are recorded in the Independence and Conflicts register and, where material, disqualify a member from voting on the section in question.

Every public draft is open for a stated consultation window, usually eight weeks. Feedback may be submitted by any party — member or non-member, broker, operator, regulator, client or counsel. Submissions are logged with a reference number. Material comments receive a written disposition indicating whether the point was accepted, partially accepted, deferred to a future revision, or declined, with reasons.

Dispositions are published alongside the final standard. A member reading a live standard can trace any clause back to the consultation record that shaped it.

Members are expected to read new and revised standards, adjust their operating procedures within the transition window stated at publication, and be prepared to demonstrate compliance if their tier requires evidence review. Where a member cannot implement a clause because of a jurisdictional constraint, they are expected to record the reason and — where useful — flag it during the next consultation cycle.

Standards are not retroactive. A change to a standard applies to new engagements from its effective date; existing bookings and contracts are governed by the version in force at the time they were entered into.

Members implementing a new or revised standard should begin by mapping the clauses to their existing procedures. Most changes affect three artefacts: the client-facing quote or engagement document, the operator-verification checklist, and the post-flight record. Updating those three artefacts typically carries a member through the majority of a revision cycle.

For questions of interpretation, the Association issues non-binding interpretive notes on request. Notes are anonymised before publication and become part of the reference material for the next scheduled review.
