Under CDM procedures, what is a 'substitution' and when does a dispatcher typically request one?
Answer: Swapping an EDCT slot from one flight to another of the same operator to optimize operational efficiency
In CDM, an airline can substitute one flight's EDCT slot for another's within the same program to manage equipment changes or delays more efficiently.
When ATC issues an Expect Further Clearance (EFC) time during an airborne hold, the dispatcher's concern regarding fuel should focus on:
Answer: Verifying the aircraft has sufficient fuel to hold until EFC plus fly to the alternate and land with required reserves
The dispatcher must verify that available fuel covers the holding period to EFC, plus the missed approach, alternate trip, and required fuel reserves.
An airline's Operations Control Center receives an ATCSCC initiative called an 'Aggregate GDP.' This type of program:
Answer: Pools slots for multiple destination airports experiencing the same weather system under one coordinated program
An Aggregate GDP combines the slot management for several affected airports into one initiative to simplify compliance for operators.
During a flow control program, what is the significance of a flight's Controlled Time of Departure (CTD)?
Answer: It is the ATCSCC-calculated departure time used to achieve the required arrival metering rate at the destination
The CTD is the time the ATCSCC assigns to ensure that when the flight arrives, the airport acceptance rate is not exceeded.
Which FAA automation system provides dispatchers and traffic managers with real-time flight position data and estimated time of arrival information used during traffic management initiatives?
Answer: ETMS/TFMS (Traffic Flow Management System)
The FAA's Traffic Flow Management System (TFMS, formerly ETMS) provides real-time NAS situational awareness including positions and ETAs used in CDM.
When an en route ARTCC sector issues a 'cruise clearance,' what altitude flexibility does the flight crew receive?
Answer: They may operate at any altitude up to and including the filed/assigned altitude at their discretion, reporting level changes
A cruise clearance allows the crew to climb to and descend from the assigned altitude at discretion, reporting leaving each altitude.
A dispatcher notices that ATC has assigned an altitude below the published Minimum Enroute Altitude (MEA) for a segment of the route. The dispatcher should:
Answer: Coordinate with the PIC to question the clearance; ATC can assign non-standard altitudes only when providing their own obstruction clearance
ATC may assign altitudes below the MEA only when they are providing their own terrain/obstruction clearance, so the dispatcher should verify ATC is aware and responsible.
