Conflicting ATC and Company Instructions

🛫 Scenario Setup

ATC clears you to FL350. Simultaneously, company dispatch sends ACARS: 'Do not exceed FL310 – engine oil issue on your aircraft.' Crew unaware of the oil issue.

💥 Failure Injection

Conflicting directives: ATC says climb, company says stay low. Crew must evaluate.

📋 Required Actions (Sequence)

  1. Acknowledge ATC clearance but delay execution
  2. Brief PM on company message
  3. Check engine oil indications – any EICAS indication?
  4. Contact dispatch for clarification – what is the specific concern?
  5. If oil indication present: treat as engine abnormal; do not climb
  6. If no indication: discuss rationally with PM before climbing
  7. If risk uncertain: stay at current altitude; declare PAN PAN if needed
  8. Document all communications
