What is the purpose of an aircraft's Flight Management System (FMS) from a dispatch planning perspective?
Answer: To provide navigation, performance management, and fuel planning data that the crew uses in flight — dispatchers use FMS capability as part of route and equipment planning
The FMS provides integrated navigation and performance management — dispatchers consider FMS capability and required navigation performance (RNP) when planning routes and approaches.
What does the term 'Required Navigation Performance (RNP)' mean for dispatch route planning?
Answer: A specified navigation accuracy requirement expressed in nautical miles that an aircraft must be capable of achieving on a given route or approach
RNP specifies the navigation accuracy a flight must achieve on a specific route or approach, and dispatchers must verify the aircraft is equipped and approved for RNP operations when planning those routes.
What is the primary reason dispatchers must understand aircraft hydraulic system limitations?
Answer: Hydraulic system failures can affect flight control, braking, and landing gear — dispatch must understand MEL implications and performance impacts
Hydraulic systems power flight controls, brakes, and landing gear, so failures create MEL conditions with specific performance penalties that dispatchers must account for in release decisions.
What is the role of Aircraft Communications Addressing and Reporting System (ACARS) in dispatch operations?
Answer: A digital data link that enables two-way communication between dispatchers and aircraft for flight plan updates, weather, and operational messages
ACARS is a digital datalink system enabling two-way communication between the operations center/dispatcher and the aircraft for weather updates, flight plan changes, and operational messages.
How does an inoperative anti-ice system affect dispatch in known or forecast icing conditions?
Answer: It may prohibit dispatch into known or forecast icing conditions depending on MEL requirements and route conditions
An inoperative anti-ice system with applicable MEL conditions may prohibit dispatch into forecast icing conditions, requiring route changes or delays until the system is repaired.
What performance penalty consideration must a dispatcher apply when an aircraft door seal is inoperative per MEL?
Answer: Potential cabin pressurization limitations that may restrict maximum operating altitude, affecting fuel burn and route planning
Door seal MEL items can impose pressurization limitations that restrict maximum operating altitude, which affects fuel burn, routing, and terrain clearance for the dispatcher's planning.
