How do you monitor a flight?
Prepreation and great situational awareness using approved flight monitoring systems. ‘
Prepare the flight using your past experience, present conditions, and staying ahead of the aircraft.
Consistently monitoring NOTAMS and the weather ENROUTE, alternates, and destinations, Always have a plan b and sometimes C and keep revising it as the flight continues.
The president is flying out on your flight and is running late for an important meeting. As the aircraft just pushed back, you notice the destination now needs an alternate but wil date a delay to refuel. What do you do?
TAKE THE DELAY.
Refuel and add the alternate. Make sure the flight is legal and safe. Even if the president is mad, you should not be in trouble for doing anything legal. Better to lose a job, rather than a license. Jobs are easier to gain.
Due to thunderstorms, you believe the flight is not unsafe. The pilot is determined to continue for unknown reasons though you discussed it. Can he continue.
Legally yes.
If you believe that a Captain is continuing into unsafe conditions after you briefed him, he may use his CAPTAIN AUTHORITY.
Always brief the pilot of what you think are the unsafe conditions. (Especially new dispatchers what you think is unsafe may be normal to him)
ASK! - Other experienced dispatchers, managers, and the pilot if they think it is unsafe.
If still unsafe ASK AND ASSIST- tell the Captain you think it is unsafe and he will be using his CAPTAIN Authoritiy to continue, but assist in what he needs.
You receive a call from a gate agent stating that your aircraft has declared an emergency and they will call you back when they land. What do you do?
Keep them on the phone if they have contact with the aircraft. Keep an open line of communication. Ask what the emergency is? Tell them to notify the flight dispatch on the line and if they need any assistance, you are here. Start passing your other flights to other dispatchers will you handle the emergency. Handle the emergency and assist the crew. Give input if you have any ideas that may help the flight.
What are some stresses that a dispatcher may encounter and how to deal with them?
Operational Stress- Pressure for on time arrival/departures. NEVER let someone push you into a bad decision. Ask another dispatcher, manager, and don’t forget the PILOT!! About what they think. If it is unsafe don’t dispatch.
Personal stresses - pressures of life, relationship, money, or death of a family member/friend. If you are not fit to dispatch and circumstances may affect your judgement, let someone know. Everyone gets stressed.
Thunderstorms are along your intended route. How might you brief the pilot.
Call the pilot. Type “Call for Radar Brief” on the release. Brief him/her along the route with updates.

When reviewing a turbine aircraft cruise performance charts, the aircraft manufacturer does not provide any data at very high altitudes and very heavy weights. What is the reason for this “Coffin’s corner”?
If the aircraft encountered an increase in G-loading (turbulence) it could possibly stall even though the indicated airspeed appears normal. High altitude stalls in turbine aircraft can be extremely dangerous.
What is a provisional airport
An airport that is listed in the OPS Specs that is authorized to be used when regular airport is not available for use. (Even if it is below landing minimums)
In the real world airlines rarely use standard alternate mins. They us the 1 nav 2 nav rule (derived alt mins) to list an alternate. Explain the 1nav 2 nav rule.
When choosing an alternate, look at the navigation approaches available for the suitable runways.
- NAV - Add 400 ft to the decision height and 1 sm to the visibility.
- NAV - Add 200 ft to decision height and 1/2 sm to visibility to the HIGHEST of the two.
Frequency of NAVAIDs must be different if using two different approach ends on a single runway (RWY 27/9) or it will be considered 1NAV rule

May a flight be dispatched to an airport that is below landing minimums at the ETD?
Yes, 121.613 only requires the weather at the destination to be at or above the authorized minimums at the estimated time of arrival for the destination.
In the takeoff calculations, if an engine fails after V1, would this be considered an “accelerate go” or “accelerate stop” decision?
Accelerate go. If the engine fails after V1, the T/O should be continued unless the aircraft is not capable of flying.
When an aircraft diverts to an alternate airport, is it required to use alternate minimums for the approach?
No. Alternate minimums are used for flight planning purposes. When the flight actually diverts to the alternate airport, the OPS SPECS for that airport apply.
When referring to the TAF to determine if a destination alternate is required before, does the dispatcher compare the ceiling to the Decision Altitude (DA) or the Decision Height (DH) on the appropriate instrument approach chart?
Decision height, DH ceiling is measured in height above a reference point on the airport surface. DA always uses MSL as a reference and this has no correlation to a ceiling and used by pilots.
Aircraft is taxiing out and noticing an inoperative fuel pump which manual to refer to?
AFM, QRH, and/or abnormal operations.
Why is it so critical to prevent build-up on the engine nacelle?
If ice builds up on the engine nacelle, it will disrupt airflow into the engine, thus reducing thrust. Also, the ice may break off and get ingested into the engine and damage the compressor blades.
Checking your NOTAMS prior to a flight, you notice closed taxiways and extremely high snow banks near your ramp. What should be expected?
Check your airport diagram for possible available taxi routes that may: increase taxi time and increase taxi fuel.
What does the VMCG stand for and what is its purpose?

Is the aircraft going to be parked in a hangar? If not is one available? is deicing equipment available? Consult someone prior to take off if it is still worth going? Would the company rather pay for hangar rather than deice?
If the takeoff runway is contaminated, would your consider using a higher or lower takeoff flap setting and why?
Use a higher flap setting because it reduces V1 speed, allowing more runway for stopping if an aborted takeoff is necessary.
Pressure altitude when combined with outside air temperature provides a critical piece of information called________ (this ultimately provides required performance data for all aircraft)
Density Altitude

Weight using contaminated runway analysis to prevent over run of the runway.
Cross wind imitations to prevent sliding off the runway sideways
What is one of the primary reasons for an aircraft manufacturer establishing a maximum recommended crosswind landing limitiation?
If this limit is exceeded, it is very easy to scrape the wingtip or the engine nacelle on the runway before the landing gear touches the runway. ( 737 usually scrapes the engine nacelle and the 777 or 747 scrape the wingtip because of long wings)

d. any other conditions that may delay landing of the aircraft.
When might you need more than minimum fuel?
- delays
- Active deicing programs
- Thunderstorms
- Peak times
- Required by MEL
- Anytime with good personal judgement
What are some ways you may be able to determine delays that may effect your flight?
Airport website with published delays, Speak to pilots/dispatchers from your company that landed or took off from locations, flight following system with other airline (watching for holding patterns) , experience (you as a dispatcher will learn characteristics of airports, seasons, or peak times)
Why is it recommended to takeoff and land with a headwind vs a tailwind?
A headwind on landing reduces the groundspeed at touchdown, thus reducing the stopping distance. A headwind on takeoff allows the aircraft to reach flying speed using less runway. Aircraft fly on AIRSPEED and they stop on Groundspeed.

Describe the characteristics of a low pressure system?
usually associated with adverse weather, but generally good visibility. Winds can be strong if isobars are close together, decreases performance, convection that can produce thunderstorms.
Describe the characteristics of a high pressure system.
Usually associated with good flying conditions, but low visibility, prevents convection, increases aircraft performance.
How would this pirep effect your flight traveling at or near that same area?
LWD UA / OV LMN280040/TM 2201/FL060/TP PA46/SK TOP060/TB MOD/IC NEG
It is good information that turbulent air is in the area. The aircraft type is a PA46, a smaller aircraft and only reporting moderate turbulence. A 737 would experience only light, if any, turbulence passing though the same air.
Brief the pilot on possible turbulent air with smaller aircraft and monitor the area for more PIREPs. Mostly likely would not effect your flight.
TVC UUA / OV TVC/TM 2206/FL360/TP A380/TB CONT SVR CHOP
What would this mean for your flight traveling in the same area?
EXTREMELY DANGEROUS!!!!
This is an urgent PIREP and the aircraft is an A380 that is experiencing continuous sever chop. A smaller 737 would experience severe to extreme turbulence and most likely experience structural damage.
Do not dispatch through severe.
Read and describe why this report may be important?
LNK UUA/OV LNK/TM 2306/ FL003/TP BE9L/ RM LLWS +/- 20kts FINAL APPROACH RWY 35
Identifier LNK
Urgent Pilot Report (UUA)
Time 2306Z
Flight Level 3000ft
Type Beech King Air 90
Remarks low level wind shear plus and minus 20kts on final approach to runway 35. If we were to dispatch this aircraft to this area, brief the pilot of low level wind shear and plan accordingly with extra fuel and maybe even an alternate.
What are some conditional remarks that may be found in a TAF
Tempo – Temporary conditions that changes are expected for less than 1hr total and half the time forecasted.
Prob– Probability. It will be followed by a number. PROB40 means there is a 40% chance of conditions occurring
BECMG-Becoming. In the US, it is used as a conditional remark meaning a gradual change.
What is a SPECI?
A special METAR due to quick changing weather such as:
Direction 45 or more in less than 15min and wind speed is 10kts or more
Visibility decreases to less than or if already below (increases to equal or exceeds) 3,2,1 mile
RVR changes to above or below 2400 feet (1/2SM)
What are some different types of TAFS?
Routine TAF. Updated every 6 hours
Corrected TAF- When there is a correction made to a previous TAF due to error
Amended TAF - Amended to forecast more accurate weather forecasts
