The air traffic rules and procedures applicable in Brazil are in accordance with Annexes 2, 11 to the Convention on International Civil Aviation and those parts applicable to aircraft, related to Procedures for Air Navigation Services - Aircraft Operations (PANS-OPS), Procedures for Air Navigation Services - Air Regulations and Air Traffic Services and the Regional Supplementary Procedures applicable to the SAM Region, except for the cases listed in GEN 1.7 and, in addition, the following:
|
|
|
1.1. The pressure for the altimeter setting QNH reported to the aircraft shall be rounded out to the nearest inferior whole hectopascal.
|
1.2. The transition altitude of each aerodrome is that contained in the instrument Approach Landing Charts (IAC) and/or in the Standard Instrument Departure Charts (SID).
|
1.3. The minimum holding level shall be always that contained in the IFR flight level table, immediately above the transition level.
|
2 FUNDAMENTAL ALTIMETER SETTING PROCEDURES
|
|
|
2.1.1. The transition level shall be defined by the Air Traffic Control unit or by the pilot whenever the unit only provides flight information service, always in compliance with the table below and in accordance with the current QNH.

Transition determining table
|
2.1.2. In order to determine the transition level, one should observe, in the left column, which aerodrome transition is and read the level at the intersection of the same line with the column corresponding to the current QNH value.
Example: The transition altitude of a given aerodrome is 4000FT; the transition level of the aerodrome will be FL065 whenever the QNH is 942.2 to 959.4hPa; it will be FL060 whenever the QNH is 959.5 to 977.1hPa; and so forth. The lower the QNH is, the higher the transition level will be.
|
|
|
2.2.1. The pressure for the altimeter setting QNH shall be reported to the arriving aircraft as soon as communications are established
|
2.2.2. Aircraft accomplishing approach procedures, that include a Penetration Path in the graphical representation (IAC), must have theirs altimeters set to QNH when they initiate the approach on the Penetration Path.
|
2.2.3. Aircraft descending under radar control, being vectored for approach procedures final portion interception or for visual approach shall have their altimeters set to QNH , when the Air Traffic Control unit so determine or authorize.
|
2.2.4. Aircraft descending to the altitude of beginning of procedure in a location not served by Air Traffic Control unit must have their altimeters set to QNH, as they pass through the Transition Level.
|
2.2.5. Aircraft under no radar control , descending to the altitude of beginning of procedure must have theirs altimeters set to the QNH setting as they pass through the Transition Level or when so determined or authorized by the Air Traffic Control unit.
NOTE: The Air Traffic Control unit must determine or authorize the introduction of the QNH setting above the transition level, whenever there is a forecast of a continuously developed approach without long portions of leveled flight
|
|
|
2.3.1. The pressure for the altimeter setting shall be reported to aircraft during the authorization for taxi and shall be set to 1013.2 Hpa (QNE) during departure, on passing through the transition altitude of the departure location.
