Pack C Miyoshi Flashcards
What do you know about the climate of four distinct seasons in Japan?
1.) WINTER: Dec - Feb. H in the West, L in the East with freezing winds. Main JS located top of tropopause near stratosphere.
2.) SPRING: Mar - May. Strong SW winds, bumpy conditions. Synoptic cyclones. Cherry blossoms late March, early April.
“Bai-U” or “Tsu-you” 1st Rainy season: Early May through late July excluding Hokkaido.
3.) SUMMER: Jun - Aug. H Press areas moving in from the Pacific. T/S & sea fog (small water droplets, visible less than 1000m. Warm moist air moving over cold ground.
Typhoon (Tropical cyclone in the Westen Pacific) Above 34kt. Aug - Oct: 2nd Rainy season.
4.) FALL: Sep - Nov. Continental & oceanic H balance over Japan, clear skies, comfortable temperatures.
What do you know about “Bai-U”, also called “Tsu-U” in Japan?
“Bai-U” or “Tsu-you” 1st Rainy season: Early May through late July excluding Hokkaido.
The Bai-u front is for add in the southern part of Japan around the beginning of May, and it gradually shifts northward and disappears by the end of July.
Typhoon category in Japan based on the maximum wind at center?
- Tropical Depression (TD): Below 34kt
- Tropical Storm (TS): At or above 34kt, below 48kt
- Severe Tropical Storm (STS): At or above 48kt, below 64kt
- Typhoon (T): At or above 64kt
Tell me what you know of Typhoon?
- August to October, major typhoon season in Japan.
- Typhoons are powerful tropical storms produced in low pressure areas of southern oceans near the equator.
- High winds, above 34kt in Japan and torrential rainfall.
- Originate out over the ocean. Typhoons reaching Japan curve first northwest then northeast in front of prevailing winds before dissipating their energy over colder sea or land.
Tropical cyclone & extratropical cyclone. When a typhoon weakens, will it change to a tropical cyclone (tropical depression TD) or an extratropical cyclone (low pressure system in the middle latitudes?
Both possible.
- If the structure of a typhoon changes, it will change to an extratropical cyclone.
- If only the intensity weakens with structural change then it will change to a tropical cyclone.
- Extratropical cyclones have frontal features, i.e. they are associated with cold fronts, warm fronts, and occluded fronts. Tropical cyclones have no fronts.
When a typhoon is moving in the NE direction, which is the dangerous semicircle?
- In the northern hemisphere the air flows towards the centre of a typhoon in a counterclockwise direction.
- The dangerous semicircle is the right hand side of the typhoon due to the stronger winds.
- *Additional INFO: High winds and waves are normally most prominent on the right hand side of the moving typhoon, known as the “dangerous semi-circle” where the speed of forward movement of the typhoon itself is added on top of the wind circulating around the typhoon. On the other hand the winds on the left (known as the Navigable semicircle) will be somewhat reduced by the forward movement of the typhoon.
What do you know about “Hutatsu-dahma low?
- When two low pressure systems exist at the same time, one in the north and another in the south of Japan.
- Occasionally observed early & late winter.
- These lows move east at a higher speed causing widespread gusty wind, heavy rain and snow.
Typical winter pressure pattern in Japan?
Characterised by low pressure in the E and high pressure in the W which makes NW wind dominant.
How do you check the RWY condition when it’s snowing?
Refer to SNOWTAM.
Typical Clear Air Turbulence (CAT) associated with jet stream.
In the northern hemisphere CAT is possible in the shaded area (frontal zone) or cold side. CAT is possible at higher altitude to the north and lower to the south.
Why did you select FL400 for cruise? What is your policy?
- Basic policy OM. 2-1)
- Select the best CRZ FL for safety, efficiency, on-time operation and passenger comfort.
SUMMARY PLAN in the FLT PLAN. Why is FL430 the next level above FL400?
ICAO RVSM Standard cruise levels (West Bound)
- 2000ft sep 2000ft - FL400
- 3000ft FL400 - FL430
- 4000ft FL430 - unlimited.
Maximum operating pressure ALT B787?
- B787-8 & 9: 43100ft
- B787-10: 41000ft
What determines maximum altitude?
It is based on MAX Climb Thrust (MCLT) with 300ft/min residual rate of climb and MAX Cruise Thrust (MCRT) with 0ft/min residual rate of climb.
T/O ALTN Airport requirements?
- WX must be at or above alternate minima at the ETA. (OM. 3-4-2)
- The airport must be selected within one hour flight distance, one engine normal CRZ SPD, wind calm (OM. 3-4-2) B787-9 1000-K: 431NM
What are the airports that can be selected as a T/O ALTN airport for NRT?
- Available airports within 431nm from RJAA
- RJTT: Haneda, RJSS: Sendai, RJGG: Chubu, RJOO: Osaka, RJBB: Kansai, RJCC: Chitose
NAV/GBAS is entered in ATC filed FLT Plan. What is available with GBAS?
- GLS Approach
- Precision approach method in which horizontal and vertical guidance is provided by a GBAS facility on the ground and is categorised as a CAT-I operation.
- GBAS (Ground Based Augmentation System) Landing System.
- GBAS consists of the following 3 ground systems installed in or near the airports: 1.) Reference receiver, 2.) GBAS control station, 3.) VDB (VHF Data Broadcast) transmitter.
- B787 is equipped with the equipment to perform GLS app as standard feature.
PBN/T1 is entered in ATC filed FLT plan. T1 means RNP AR Approach with RF. Can you fly this type of approach?
RNP AR Approach is not approved for Air Japan. (AOM Bulletin 2023-06)
How many GPS Satellites do you need for RNAV?
23 satellites (OM S-4-5, 2)
Center of Gravity (CG) envelope in the Weight & Balance (W&B) Manifest graph. Is this the certified CG envelope as described in the AOM Limitations Chapter?
No, it is called the CG Working Limit.
Why is there three MTOW’s in the W&B CG envelope?
Flex MTOW A, B & C (AOM WB 50.3) (AOR WB.2)
Threats at Naha airport (ROAH)?
-This airport is situated 10nm SW of USAF Kadena Air Base (RODN). To maintain separation, Naha arrivals must commence approach from a lower altitude (1200’), also MAA is restricted to 1200’
- Naha Departures to the north are occasionally restricted to maintain 1200’after T/O as well.
Difference between Displaced Threshold and Stopway Marking?
- Displaced: Arrow indicated both sides have the same strength.
- Stopway: Chevron indicates the strength of the Stopway is weaker than the RWY.
Where are the onboard legal documents stored? Can you visually check all of the documents?
- It is stored in the Certification Holder behind the Captains seat.
- No. The certification holder is sealed and locked. When the seal is broken the captain shall check each document separately.
Exterior inspection: When you view the airplane far from the front, what will your general inspection be?
- Airplane is level, no damage to the aircraft as far as the eye can see, beacon light is off, signs of a bird strike etc.
Exterior inspection: If you find the gear pin still installed, what will you do?
- Call maintenance to remove it.
Exterior inspection: Oxygen pressure relief disc. Is it acceptable if the colour is not green?
The original colour green may fade but the disc functions normally. If the disc is blown out, it means crew oxygen is discharged and the cylinder needs to be inspected.
Exterior inspection: When a cargo loader is parked near the forward cargo door (right side of the aircraft), what becomes difficult to inspect?
Static ports.
Exterior inspection: What is the purpose of the vertical red line on the engine?
The red line indicates hazard area when the engine is running. Stay aft of the line when approaching from the back.
Exterior inspection: What will you inspect around the main gear area?
- Tires, brakes and wheels.
- Gear strut, actuators and doors.
- Hydraulic lines and electrical wiring.
- Gear pins removed.
