TUI Case Study Flashcards by Jack Ryan

What is the key in the Case Study?

6 main things

Treat it like it’s a real event (lean into role play)

Evidence understanding of TUI values and Competencies throughout (Ethos + Competency Evidence)

Two-way communication (ask if any questions)

Work efficiently to finish the questions and read all info.

Overview to demonstrate knowledge (ask if any questions again)

What does 051212 mean on a TAF? How else may this be written (more normal)?

Period of validity is from 1200 on the 5th to 1200 on the 6th

0512/0612

What is a SIGMET?

An inflight weather advisory for significant meteorological hazards.

What are the 2 (11) main types of internationally-recognised SIGMETS?

Volcanic Ash (VA)
Tropical Cyclone (TC)

Other (thunderstorm; turbulence; mountain waves; icing/sleet/hail; dust or sandstorms; radioactive cloud)

How long are SIGMETs valid for?

4 hours, or for hurricane, 6 hours

What is fuel bias?

Figure that reflects the different consumption rates of different aircraft.

What does ETOPS stand for? What does this mean?

Extended range Twin Operations; TUI Airways are permitted to fly up to 180 minutes away from a suitable airport.

Passenger breakdown in OFP?

male/female/children

What is SELCAL Code?

A signalling method which can alert an individual aircraft that a ground station wishes to communicate with it, often used when out of VHF radio range.

Crew composition?

pilots/cabin crew

What 4 things does trip fuel include?

Fuel for take-off and climb taking into account expected departure routing. Fuel for cruise including any enroute climbs. Fuel for descent taking into account the expected arrival procedure. Fuel for an approach and landing at destination.

What is contigency fuel?

Fuel carried in case of deviations from the expected fuel consumption data, forecast meteorological conditions, planned routings/cruise altitudes. Percentage of planned trip fuel.

First alternate fuel?

Fuel for missed approach at destination aerodrome. Fuel for climb, cruise and descent to alternate aerodrome, accounting for expected routing. Fuel for executing approach at alternate aerodrome.

Final reserve fuel?

Fuel required to fly for 30 minutes at holding speed at 1500 feet above aerodrome elevation.

Required block fuel

Sum of taxi fuel, trip fuel, contingency fuel, alternate fuel, final reserve fuel. Normally the fuel an aircraft will dispatch with unless Captain deems it necessary to carry more.

Extra fuel?

Taken at discretion of commander

Dry operating weight?

Total weight of aircraft with no pax. , fuel, cargo, or baggage. DOES INCLUDE crew, crew baggage, catering

Payload and standard weights?

Total weight of pax. , baggage and cargo Male: 83kg; Female: 69kg; Child: 35kg; Baggage: 17kg per bag.

Cost index comparison?

Resultant gain/loss in time and fuel consumption if an alterantive CI is entered into FMC.

Zero fuel weight?

Weight of aircraft with all contents minus weight of usable fuel.

Trip fuel comparison?

Gain/loss in fuel consumption is actual aircraft weight is different to planned weight.

What is perhaps a good idea to do after each stage of the briefing?

Ask if there's anything the Captain wants to add. (Two-way briefing)

What do: MI; SH; TS; BC; DZ; RA; GR; PL; BR; FG; HZ; FU mean?

Shallow; Showers; Thunderstorms; Patches; Drizzle; Rain; Hail; Ice Pellets; Mist; Fog; Haze; Smoke.

What is the dew point?

The temperature at which moisture starts to condense.

What is a TEMPO?

A temporary weather trend. Change in wind, visibility, weather, or sky condition that will last for less than an hour, or if recurring, in total for less than half of the duration of the TEMPO.

What is a FROM group?

A rapid change in prevailing conditions is expected. Occurring in less than 1 hour. From given 4-digit hour-minute code, to next group or end of current forecast.

What is a BECMG group?

Used when a gradual change in conditions is expected, usually over 2 hours. Weather will change to the given forecast inside the the BECMG group at some time within the given limits.
