A Part 121 dispatcher is reviewing a weather product showing a convective SIGMET for an area the flight will cross in 45 minutes. The SIGMET covers embedded thunderstorms. What is the dispatcher's best course of action?
Answer: Coordinate with the crew on a deviation route and update the dispatch release with revised fuel and routing
Embedded convective activity requires proactive rerouting coordination with the crew and an updated dispatch release reflecting any fuel or routing changes.
What is the role of the dispatcher in the Safety Management System (SMS) of a Part 121 air carrier?
Answer: Dispatchers are hazard reporters and risk mitigators, responsible for identifying and communicating operational safety threats
Under FAA SMS requirements, dispatchers are frontline safety contributors who identify hazards, report occurrences, and participate in risk mitigation.
An aircraft departs without a signed dispatch release due to a system outage. What regulatory action is required?
Answer: The flight must be immediately recalled or grounded at the first opportunity; departing without a release is a regulatory violation
14 CFR 121.663 prohibits operation without a valid dispatch release; a departure without one is a violation requiring immediate corrective action.
What is the significance of ETOPS (Extended Operations) authorization for a dispatcher planning a transoceanic flight?
Answer: The dispatcher must verify the aircraft and carrier have the required ETOPS rating and plan diversion airports within the authorized diversion time
ETOPS requires verified aircraft/carrier authorization and mandatory adequate en-route diversion airports within the approved diversion time limit for the specific operation.
A dispatcher is told by a crew that an MEL item affecting navigation accuracy has been deferred. The planned route crosses mountainous RVSM airspace. What must the dispatcher verify?
Answer: That the aircraft remains RVSM-approved with the deferral in effect and that the MEL provisions allow the intended operation
RVSM authorization requires specific equipment standards; an MEL deferral affecting navigation accuracy may invalidate RVSM approval for that flight.
Under 14 CFR 121.570, what must a dispatcher do if a passenger or crew member reports a potential security threat during a flight?
Answer: Immediately notify the appropriate authorities and provide the PIC with all relevant information and guidance
Security threats require immediate dispatcher action including notifying TSA/law enforcement and fully supporting the PIC with information during the event.
What is the purpose of a Dispatch Deviation Guide (DDG) in relation to MEL items?
Answer: It provides maintenance and dispatch procedures for operating with specific inoperative equipment within approved MEL limitations
The DDG translates MEL provisions into specific operational and maintenance procedures, helping dispatchers and maintenance work together within approved limits.
