    PEOPLE’S REPUBLIC OF BANGLADESH
    Aeronautical Information Services AIP Supplement
    Civil Aviation Authority, Bangladesh
    Headquarters, Kurmitola,
    Dhaka-1229, Bangladesh.

    Publication Date: 07 DEC 2017. EFFECTIVE Date: 010000 FEB 2018.

    Subject: ESTABLISHING AIR DEFENCE IDENTIFICATION ZONE OVER BANGLADESH
    Introduction
    As per the convention of International Civil Aviation (Chicago Convention), every state has
    complete and exclusive sovereignty over the airspace above its territory which can be ensured by
    imposing Air Defence Identification Zone (ADIZ). Bangladesh is establishing an ADIZ to form the
    first line of defence against aerial intrusions into Bangladesh airspace as this is vital to the national
    security. The ADIZ will be known as the Bangladesh ADIZ.
    The ADIZ will cover the airspace over the entire territory of Bangladesh as defined by its
    international border with India and Myanmar, and will be extended over the adjoining sea to the
    south as delineated by the following coordinates:
    (1) 210744.80N 891356.50E
    (2) 181554.12N 892147.56E
    (3) 164328.74N 892554.37E

    (5) 200332.00N 915031.80E
    (6) 175234.06N 901504.66E
    The map shown in Annex A shows the Bangladesh ADIZ boundary
    PROCEDURE FOR BANGLADESH ADIZ FLIGHTS
    All flights of aircraft civil/military, Bangladeshi or foreign originating within the ADIZ and those
    penetrating the Bangladesh ADIZ shall obtain prior permission and Air Defence Clearance (ADC).
    The procedure for obtaining ADC is outlined in the following paragraphs:
    PROCEDURES FOR AIR DEFENCE CLEARANCE
    a. Aircraft intending to operate into, through or within the Bangladesh ADIZ shall obtain ADC
    number from the appropriate ATS unit before takeoff, except that the local flights
    conducted at any airport within, Dhaka FIR and within the relevant ATZ at or below 1000ft
    AGL. Shall not be required to get ADC number.
    b. All aircraft intending to overfly Bangladesh ADIZ or land in any airfield within Dhaka Flight
    Information Region (FIR) shall obtain ADC 10 minutes before entering the Bangladesh
    ADIZ. In case of departures from adjacent FIRs, where the prerequisites of 10 minutes
    advance notice is not feasible, ADC number shall be obtained before departure. The local
    flights at an airport having Control Zone when required/approved by ATC to operate
    beyond 05 NM but within the Control Zone shall not be required to get ADC number.

    AIP SUPP
    01/18
    01 FEB 2018 c. ADC number shall be valid for the entire route, irrespective of intermediate halts for flight
    originating in and transiting through the Bangladesh ADIZ/Dhaka FIR.

    d. When departure is delayed by more than 02 hour at the aerodrome of departure or at
    intermediate halts, a fresh ADC number shall be obtained.

    e. In the event of communication difficulties at the place of departure, or delay in receipt of
    ADC number, the aircraft equipped with appropriate radio equipment may be allowed to
    take off with instructions to obtain ADC number immediately after airborne from the
    appropriate ATS unit.

    f. General Aviation/Chartered aircraft intending to operate to and from an airfield where no
    Air Traffic Services are available, shall obtain ADC number from the nearest BAF ATC Unit.
    The BAF ATC Unit will advise the appropriate ATS unit regarding the movement of that
    aircraft.

    g. Scheduled/Chartered/General Aviation aircraft returning to the aerodrome of departure
    on the same day may be issued with ADC number for return flight also. In the event of
    delay for more than two hour in excess of the estimated departure time for the return
    flight, a fresh ADC number shall have to be obtained.

    h. Unless in emergency, any aircraft entering the Bangladesh ADIZ and /or not following the
    appropriate ATS Routes shall be required to intimate the appropriate ATS Unit not less
    than 01 hour before the estimated entry.

    i. Any aircraft flying over the sea shall obtain clearance from appropriate ATS Unit to fly
    towards the land mass of Bangladesh.

    j. Aircraft approaching Bangladesh ADIZ off the ATS Routes shall provide the estimated time
    over the ADIZ boundary at least 10 minutes in advance.

    k. If unable to establish and maintain radio communication with appropriate ATS unit, the
    pilot shall contact the nearest Air Defence Unit on International Guard Frequency
    121.50MHz/6826 Hz/500Hz for positive identification prior to entering Bangladesh ADIZ.

    l. Unless otherwise authorized by appropriate ATS Authority, no aircraft will operate into,
    within or across Bangladesh ADIZ without functional radar transponder and automatic
    pressure altitude reporting equipment that automatically replies to interrogations by
    transmitting pressure altitude information in 100 ft increments.

    m. Aircraft flying without a valid ADC number or failing to comply with any restriction or
    deviating from flight plan will be liable to interception by Bangladesh Air Force Interceptor
    aircraft according to ICAO Standard Interception Procedure.

  • Tại sao BR đc gọi là Mist trong bản tin metar ???

    There are a few things in a pilot’s life that affects him as much as the METAR.  The METAR can ground you or tell you that you’re legal to try an approach.  It’s one of those few things which follows you on every flight.  Since a pilot spends a fair amount of time reading these things, occasionally something odd pops up.  And then it nags at you.  An example of that is the METAR descriptor GR.  Why does GR mean hail?  Wouldn’t you think they’d choose HL?  Perhaps that’s too close to HELL.  And that might confuse pilots who frequently see SS (Sandstorms) DS (Dust Storms) and VA (Volcanic Ash) which I think of as forms of weather hell.

    So I decided to look at the whole list of METAR descriptors.  Here they are:
