What is the difference between an AIRMET SIERRA and an AIRMET TANGO in terms of the hazard they describe?
Answer: SIERRA covers IFR conditions and mountain obscuration; TANGO covers turbulence
AIRMET Sierra addresses IFR conditions and mountain obscuration, while AIRMET Tango addresses turbulence, strong surface winds, and low-level wind shear.
A flight is approaching a destination airport that has just issued a SPECI (Special Meteorological Report) showing conditions below the filed alternate minimums. What must the dispatcher do?
Answer: Contact the flight crew immediately and evaluate whether a new alternate must be designated with sufficient fuel
A SPECI showing conditions below alternate minimums requires the dispatcher to immediately assess whether the current alternate is still valid and whether additional fuel or a new alternate is needed.
Under what conditions is a Part 121 dispatcher required to withhold a dispatch release?
Answer: When the dispatcher determines the flight cannot be conducted safely based on available information
A dispatcher has the authority and obligation to withhold the dispatch release whenever they determine that the flight cannot be conducted safely.
Which radio frequency is used in the United States as the universal emergency frequency for all civil aviation communications?
Answer: 121.5 MHz
121.5 MHz is the international civil aviation emergency frequency, monitored by ATC facilities and aircraft in flight.
A dispatcher is planning a flight that will cross an ADIZ (Air Defense Identification Zone). What communication requirement must be included in the dispatch planning?
Answer: The flight must file an IFR or DVFR flight plan and adhere to position reporting requirements for ADIZ penetration
Flights penetrating an ADIZ must file an IFR or DVFR flight plan and comply with two-way radio communication and position reporting requirements.
What is the significance of a 'gate hold' procedure from a dispatcher's communication perspective?
Answer: ATC or the airline may implement a gate hold to manage traffic flow; the dispatcher must coordinate updated departure times and fuel implications with the crew
Gate holds require the dispatcher to communicate revised departure times to the crew, reassess fuel burn, and update downstream operations accordingly.
What is the dispatcher's role when a NOTAM is issued for a Temporary Flight Restriction (TFR) that overlaps a flight's planned route?
Answer: Review the TFR boundaries and timing, and reroute the flight prior to departure to avoid the restricted airspace
The dispatcher must identify TFR boundaries and valid times, and reroute the flight to avoid the restricted airspace if the TFR is active during the planned flight.
