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?
Tell me what you know of Typhoon?
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.
When a typhoon is moving in the NE direction, which is the dangerous semicircle?
What do you know about “Hutatsu-dahma low?
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?
SUMMARY PLAN in the FLT PLAN. Why is FL430 the next level above FL400?
ICAO RVSM Standard cruise levels (West Bound)
Maximum operating pressure ALT B787?
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?
What are the airports that can be selected as a T/O ALTN airport for NRT?
NAV/GBAS is entered in ATC filed FLT Plan. What is available with GBAS?
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?
Where are the onboard legal documents stored? Can you visually check all of the documents?
