Question 1

What is the purpose of an aircraft's Flight Management System (FMS) from a dispatch planning perspective?

Accepted 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

Answer

The FMS provides integrated navigation and performance management — dispatchers consider FMS capability and required navigation performance (RNP) when planning routes and approaches.

Question 2

What does the term 'Required Navigation Performance (RNP)' mean for dispatch route planning?

Accepted Answer

A specified navigation accuracy requirement expressed in nautical miles that an aircraft must be capable of achieving on a given route or approach

Answer

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.

Question 3

What is the primary reason dispatchers must understand aircraft hydraulic system limitations?

Accepted Answer

Hydraulic system failures can affect flight control, braking, and landing gear — dispatch must understand MEL implications and performance impacts

Answer

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.

Question 4

What is the role of Aircraft Communications Addressing and Reporting System (ACARS) in dispatch operations?

Accepted Answer

A digital data link that enables two-way communication between dispatchers and aircraft for flight plan updates, weather, and operational messages

Answer

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.

Question 5

How does an inoperative anti-ice system affect dispatch in known or forecast icing conditions?

Accepted Answer

It may prohibit dispatch into known or forecast icing conditions depending on MEL requirements and route conditions

Answer

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.
