Define the term “Marginal”
Applies to alternate airports, Airline defines the term. some use 3/4sm (4000 RVR) and some use the NWS term “LIFR” meaning 500ft and 1sm visibility. If the weather is at or below the designated value(s) an addition alternate must be selected.
Where do you find takeoff minimums for a specific runway?
Jepp 10-9A chart
The pilots report an engine failure in flight to you, As a dispatcher what are you responsibilities?
Suggest the nearest suitable airport in point of time at which a safe landing can be made, if the pilots have not already made that decision and diverted. You must contact the diversion airport and arrange a gate, possibly hotel rooms for crew and passengers, and or coordinate a company aircraft to that airport to pick up the passengers if it is a remote airport, contact MX control and advise the situation and inform your supervisor
Do we have authority in the AGS to fly to Canada, Mexico, Bahamas, or Alaska as a domestic flight?
No, we do not have ops specs A012
A landing requirement on a dry runway must be completed within 60% of the runway length. What is the wet runway penalty?
An additional 15% is added to the 60% requirement, it may be necessary to reduce the allowable landing weight
Pilots and dispatchers are responsible for:
Preflight, delay and dispatch release
What is ORH?
Quick Reference Handbook, for use by the pilots in the cockpit for problems in flight.
Where do we find the dispatch and flight release rules?
Part 121, subpart U
In preflight planning for an alternate, the airport has only one straight-in ILS approach. What safety factor do you add to the approach minimums?
200ft to ceiling and 1/2 SM to visibility = 400 & 1

Fuel for the trip plus missed approach, fuel to the most distant alternate if required, plus fuel for 45 minutes
Can the aircraft depart in moderate or heavy freezing rain?
No, but it can take off in light freezing rain
Is mist (BR) considered to be a wet runway?
No, it is only a restriction to visibility. Fog is a wet runway condition, if the observer can see only up to 5/8 SM, then the condition is called fog. More than 5/8 SM up to 6 SM is considered mist.
Which Part 121 operations do not require a dispatcher?
Supplemental and Commercial Operators.
What information must you provide the pilots?
All available current reports on airport conditions & irregularities of VNAVAIDS that affect safety. Also all available weather reports/forecasts on the route and the airports to be used. During flight, updates on weather and airport conditions.
Which regulation governs dispatcher schools and their training programs?
Part 65
What are the Part 121 requirements for you to operate as a dispatcher at an air carrier?
Part 121.422 - Initial & Ground Training ( 40hrs)
Part 121.427 - Recurrent Training (20hrs/year)
Part 121.463 - Dispatcher Qualifications
When does your dispatcher certificate expire?
Never
What are the characteristics of a high pressure system
A center of pressure surrounded on all sides by lower pressure, rotating clockwise and decending
How does fog form?
- by cooling air to its dewpoint
- by adding moisture to the air near the ground
How long is a METAR valid?
It is only valid at the time of the report & normally updated every hour.
How long is a TAF valid?
Issued 4x a day for 24 or 30 hours depending on airport
What is the CCFP?
Collaborative Convective Forecast Product - Issued 2, 4 or 6 hours with polygons showing convective activity and a forecast where thunderstorms will be in the next 1-2 hours
How many types of satellite imagery are available?
3, Visible, infrared, and water vapor
How does a turbine engine work?
Suck, Squeeze, Bang, Blow
How does the aircraft obtain AC and DC electrical power?
Primary power from 2 AC engine-driven generators & the APU, DC power comes from batteries and transformers which convert 115 AC to 28v DC
What emergency equipment is on board the aircraft?
Life rafts, life preservers, megaphones, crash ax, first aid kits, slides, floor & internal general lighting, exit signs, flares, ELT, oxygen masks, fire extinguishers, fire detectors, instruction cards
Describe Method I vs Method II drift down.
1 method requires rerouting the aircraft around high terrain & high MEAs, the other method allows reduced payloads on high MEAs over mountains. The concern is the loss of an engine.
What is Class I and Class II navigation?
Class I allows for operation within the service volume of land-based NAVAIDS, you can fly up to one hour beyond that range as long as you can fix your position in one hour with a land-based NAVAID. Class II is operation of the aircraft beyond the service volume of land-based NAVAIDS. You can operate GPS in Class I airspace but you must always have 2 VORs ON as back up. Ops Spec A002
Besides a comp check upon initial or recurrent training, what other requirement must be met?
Familiarization ride is required with 90 days for a total of 5 hours observing cockpit operations.
Can the pilots accept a LAHSO clearance?
No, it is not allowed in our ops spec
Can we operate in Class G airspace to or from an airport?
Yes, if we meet 4 conditions.
1. The airport has instrument approach
2. An official source of weather
3. Traffic advisories and status of services and facilities
is available
4. Facilities and services exist to safely conduct IFR
operations
With 3 transmissometers (RVRs), which one is controlling?
TDZ is controlling, Mid and roll-out are advisory
What requirement must be met for a PIC to conduct and instrument approach with RVR of less than 400?
Minimum of 100hrs in left seat, he is qualified for jet lower minimums less than 4000 RVR (3/4SM) if:
a) the runway has precision instrument (all weather)
runway markings or centerline lights
b) performance data is based on a wet runway
When a significant delay, reroute, or change of cruise altitude occurs (not in the original release), the PIC must notify the dispatcher. Define “Significant”
- Delay of more than 15 min from ETA
- More than 100 NM off course
- More than 4000 ft from planned cruise altitude
Who can initiate an amendment?
Captain and dispatcher
A domestic flight stops at an enroute airport and is delayed with a MX issue. When does the release expire?
60 min after landing
A MX issue is discovered on preflight and a mechanic is called to the aircraft which requires a logbook entry. The mechanic can only do 2 things
1: repair the item in question
2: defer the item (DMI) for later MX per the MEL
Prior to departure the destination was forecast to be VFR. Upon arrival the runways are wet. Can the crew land?
Yes, they must add 15% to the actual landing distance
What significant weather must be recorded in the aircraft logbook?
Sever or extreme turbulence and lightning strikes. MX will inspect the aircraft to determine airworthiness
Can a landing be made when in receipt of a “nil’ breaking action report for the runway in use?
No, if from a reliable source (another airline pilot or airport manager)
What is the ARFF index?
Airport Rescue Fire-Fighting equipment requirements for an air carrier airport
How long does an unissued departure clearance remain active in the FAA computer before being automatically deleted by ATC?
1 hour. The pilot or dispatcher must ask ATC to keep it open before the “dead drop” time.
