About Japan | History - Geography

---

Japan, island country lying off the east coast of Asia. It consists of a great string of islands in a northeast-southwest arc that stretches for approximately 1,500 miles (2,400 km) through the western North Pacific Ocean. Nearly the entire land area is taken up by the country’s four main islands; from north to south these are Hokkaido (Hokkaidō), Honshu (Honshū), Shikoku, and Kyushu (Kyūshū).

Honshu is the largest of the four, followed in size by Hokkaido, Kyushu, and Shikoku. In addition, there are numerous smaller islands, the major groups of which are the Ryukyu (Nansei) Islands (including the island of Okinawa) to the south and west of Kyushu and the Izu, Bonin (Ogasawara), and Volcano (Kazan) islands to the south and east of central Honshu. The national capital, Tokyo (Tōkyō), in east-central Honshu, is one of the world’s most populous cities.

1- A flight plan shall not be submitted more than 120 hours prior to the estimated off-block time (EOBT) of the flight.

2- An IFR flight plan shall be submitted at least 30 minutes before EOBT. However, it is desirable to submit the flight plan within 2 hours before EOBT in order to ensure the effect of air traffic flow management.

3- In case of the flight across a FIR boundary, flight plan shall be submitted by time required by the ATS authority concerned.

6) Cruising altitude and route
7) Point of first intended landing and the total estimated elapsed time
8) True airspeed at cruising altitude
9) Radio equipment (communication equipment/navigation and approach aids/ATC transponder)
10) Alternate airports (exempted in case of IFR (no ALTN AP designated) or VFR)
11) Amount of fuel on board expressed in hours
12) Total persons on board

Note:"Point of first intended landing and the total estimated elapsed time" denotes that the elapsed time between airborne time and estimated time of arrival.SAR

For IFR flights, the time at which it is estimated that the aircraft will arrive over the designated point*2, defined by reference to navigation aids, from which it is intended that an instrument approach procedure will be commenced, or if no navigation aid is associated with the aerodrome, the time at which the aircraft will arrive over the aerodrome. For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.

Designated point a commencing point on instrument approach procedures of ADF, VOR, TACAN, VOR/DME, ILS, LOC and RNAV respectively. However, on ILS approach procedure in which no commencing point is indicated, designated point is corresponding to the nearest holding fix to the destination: established either in ILS approach procedure, or en-route for the aircraft to commence an ILS approach. In case of instrument approach procedure in which the holding pattern is not established at the commencing point, designated point corresponds to the nearest holding fix to the commencing point establishes enroute for the aircraft to follow this approach procedure.

Sending Of Air Traffic Services Messages

Our teams fulfill all your travel needs, leaving you feeling comfortable, safe, and contented with your trip.

The Kind Of Air Traffic Services Messages

Air traffic services messages (Air traffic services messages in this context comprises filed flight plan messages, delay messages, modification messages and flight plan cancellation messages) relating to traffic into or via the FUKUOKA FIR shall be addressed as stated below in order to warrant correct relay and delivery.

The filed flight plan messages (FPL MSG) shall be transmitted to related ATS units based on AIP ENR 1.10 Flight Plan.

The delay messages (DLA MSG) shall be transmitted to related ATS units when the departure of an aircraft, for which basic flight plan data has been sent, is delayed by more than 30 minutes after the estimated off-block time (EOBT) contained in the basic flight plan data.

*when EOBT is delayed 30 minutes and over 0000 (UTC), it should be based on the message of 2.3.

The modification messages (CHG MSG) shall be transmitted to related ATS units when any change (it removes, when it corresponds to the message of 2.2.) is to be made to basic flight plan data contained in previously transmitted FPL data.

Note:The explanation about ADIZ (Air Defense Identification Zone) and a detailed procedure can be checked by AIP ENR5.2.5.

Unlawful Interference

1. An aircraft which is being subjected to unlawful interference shall endeavor to notify the appropriate ATS unit of this fact, any significant circumstances associated therewith and any deviation from the current flight plan necessitated by the circumstances, in order to enable the ATS unit to give priority to the aircraft and to minimize conflict with other aircraft.

2. If an aircraft is subjected to unlawful interference, the pilot-in command shall attempt to land as soon as practicable at the nearest suitable aerodrome or at a dedicated aerodrome assigned by the appropriate authority unless considerations aboard the aircraft dictate otherwise.

3. If there is unlawful interference with an aircraft in flight, the pilot-in-command shall attempt to set the transponder to Mode A/C, Code 7500 in order to indicate the situation.

If circumstances so warrant, Code 7700 should be used instead.

Note:When a pilot-in-command has selected Mode A/C, Code 7500 and the request of ATC to confirm this setting will not be replied, the absence of reply from the pilot will be taken ATC as an indication, that the use of Code 7500 is not due to an inadvertent false code selection.

4. The following procedures are intended as guidance for use by aircraft when unlawful interference occurs and the aircraft is unable to notify an ATS unit of this fact.

• If the pilot-in-command cannot proceed to an aerodrome in accordance with the provision of 2 above, he/she should attempt to continue flying on the assigned track and at the assigned cruising level at least until able to notify an ATS unit or until within radar.

• When an aircraft subjected to an act of unlawful interference must depart from its assigned track or its assigned cruising level without being able to make radiotelephony contact with ATS, the pilot-in-command should, whenever possible:

i. Attempt to broadcast warnings on the VHF channel in use or the VHF emergency frequency, and other appropriate channels, unless considerations aboard the aircraft dictate otherwise. Other equipment such as on-board transponders and data links should also be used when it is advantageous to do so and circumstances permit.

ii. Proceed at a level which differs from the cruising levels normally used for IFR flight by.

a) 150m(500ft) in an area where a vertical separation minimum of 300m(1,000ft) is applied.

b) 300m(1,000ft) in an area where a vertical separation minimum of 600m(2,000ft) is applied.
