Decision making can be a complex, team focused process.FORDEC stands for Facts, Options, Risks, Decision, Execution, Check. This model guides crews through a logical sequence: gather facts, generate options, assess risks, make a decision, execute the plan, and check the outcome. It is especially useful for complex or ambiguous situations where collaboration is needed.
The model was developed (or at least formalised) through work by Lufthansa and the German Aerospace Center (DLR) around the early-1990s as part of CRM/aircrew decision-making frameworks.

RMATE stands for Recognise the situation, Maintain control of the aircraft, Assess the problem, Take appropriate action, Evaluate the need to land. This model emphasises continuous monitoring and adaptation, encouraging crews to reassess and adjust as situations evolve.
It is well-suited for ongoing, dynamic scenarios where evolving threats or system degradations require a flexible and cyclic approach rather than a single linear decision point.
Although not formally attributed to a specific manufacturer, RMATE is commonly found in Boeing training materials and airline CRM syllabi aligned with Boeing operations. Its origin appears to be industry-derived rather than proprietary, possibly evolving from practical flight operations and line-training environments rather than academic or regulatory frameworks. As such, it has become a practical, operator-level decision aid rather than a formally standardised model like FORDEC.

ANCAAM stands for Aviate, Navigate, Communicate, Assess, Action, Manage. This sequential model is well-suited to time-critical events, ensuring flying the aircraft remains the top priority before moving through structured assessment and action steps.
It helps maintain order and focus under pressure, especially during high workload or emergency scenarios.
ANCAAM builds on the traditional “Aviate–Navigate–Communicate” mantra and appears to be an instructional extension developed within training and CRM environments. While not formally standardised by ICAO or regulators, it is increasingly used in threat-and-error management and CBTA-aligned syllabi as a practical decision-making aid.



| Situation Type | Role of the Captain | Role of the Company |
|---|---|---|
| Emergency/Time-Critical | Lead decisively, act without delay. | Notify after safety is ensured. |
| Operational Delay/Option | Consult when time permits. | Offer information, not commands. |
| Non-Urgent Tech/Dispatch | Make informed decisions, escalate if unsure. | Provide guidance based on policy/SOP. |
