  1. What is the primary difference between a Victor airway and a Jet Route (J-Route) in the US National Airspace System?

    Answer: Victor airways are from 1,200 ft AGL up to but not including 18,000 ft MSL; Jet Routes are FL180 to FL450

    Victor airways exist from 1,200 ft AGL up to but not including 18,000 ft MSL, while Jet Routes (J-routes) cover FL180 to FL450 within Class A airspace.

  2. A dispatcher is planning a flight that requires crossing the ADIZ (Air Defense Identification Zone). What filing requirement is most important?

    Answer: A Defense VFR (DVFR) or IFR flight plan must be filed and a position report made before entering the ADIZ

    Pilots and dispatchers must file a DVFR or IFR flight plan before entering the ADIZ, and report position to ATC to avoid interception.

  3. When selecting an alternate airport on a domestic flight plan, what weather minimum must the forecast show at the alternate during the ETA ±1 hour window (standard alternate minimums)?

    Answer: Ceiling 600 ft and visibility 2 SM for precision approach, or ceiling 800 ft and visibility 2 SM for non-precision approach

    Standard alternate minimums are 600-2 for precision approaches and 800-2 for non-precision approaches during the ETA ±1 hour window.

  4. What does 'MEA GAP' indicate on an IFR enroute chart?

    Answer: A segment where VOR navigation signal reception is not guaranteed at the MEA, requiring a higher altitude for continuous reception

    An MEA GAP indicates that on that segment the navigation signal may not be received at the MEA, and pilots/dispatchers must be aware of potential navigation unreliability.

  5. How does a dispatcher determine the appropriate cruise altitude for a long-haul flight considering step climbs?

    Answer: By analyzing the aircraft weight at various points, optimum altitude charts, and fuel burn tradeoffs as fuel is consumed and weight decreases

    Step climbs exploit the aircraft's improving optimum altitude as fuel burns off, and dispatchers plan these by analyzing weight, altitude performance tables, and fuel savings.

  6. What is a 'random route' or 'random RNAV route,' and when would a dispatcher use it?

    Answer: A direct or non-standard route filed between waypoints not following published airways, used to reduce track miles and fuel burn

    Random RNAV routes allow dispatchers to file direct or non-airway paths between fixes, reducing distance and fuel when airspace and traffic allow.

  7. In route planning, what is the purpose of a Minimum Crossing Altitude (MCA)?

    Answer: It specifies the lowest altitude at which an aircraft must cross a certain fix when proceeding on a higher MEA segment ahead

    An MCA ensures the aircraft is at a sufficient altitude before it reaches a fix where the MEA ahead is higher, preventing obstacle or signal coverage issues.
