ENR 1.7 ALTIMETER SETTING PROCEDURES

 

1 INTRODUCTION

1.1. The altimeter setting procedures conform to those contained in ICAO Doc 8168-OPS/611.
1.2. Altimeter setting values are given in hectopascals rounded off downward to the nearest whole hectopascal. On request the values will, however, be provided in tenths for landing.

2 BASIC PROCEDURES

2.1 Transition altitude / Transition level

2.1.1. The transition altitude for HELSINKI FIR is 1500 M (5000 FT) MSL except for Kirkenes terminal control areas ENKR TMA CENTER and ENKR TMA WEST where transition altitude is 2150 M (7000 FT) MSL.
2.1.2. The transition level - based on the local actual QNH value - is determined by the appropriate ATS-unit.

2.2 Altimeter setting values used in different phases of the flight

2.2.1. The vertical displacement of aircraft on IFR and VFR flights is expressed in terms of:
  1. altitudes - determined from an altimeter set to QNH -during flight at or below the transition altitude or below the lowest usable flight level;
  1. Flight levels - based on an altimeter setting of 1013.2 HPA - during flight above the transition altitude or at or above the lowest usable flight level.
 
2.2.2. Take-off and climb
2.2.2.1. The aerodrome QNH setting is made available to aircraft in routine take-off data.
2.2.2.2. Vertical position of aircraft during climb shall be expressed in terms of altitude until reaching the transition altitude above which it shall be expressed in terms of flight level.
2.2.3. En Route
Note: See also para 5. below.
2.2.3.1. QNH setting is available on request from ATS units for use in determining:
  1. adequate terrain clearance;
  2. cruising altitude during flight below flight level system.
2.2.4. Approach and landing
2.2.4.1. The aerodrome QNH setting and transition level are made available in routine information for arriving aircraft. QFE will be passed on request only.
Note: In Finland the aerodrome QFE setting always expresses the atmospheric pressure at aerodrome elevation.
2.2.4.2. The vertical position of aircraft during approach shall be expressed in terms of flight level until reaching transition level below which it shall be expressed in terms of altitude, except that after approach clearance has been issued and the descent to land is commenced the vertical position above the transition level may be expressed in terms of altitude provided, that level flight above transition altitude is not anticipated.

3 LOWEST USABLE FLIGHT LEVEL

3.1. The lowest usable flight levels are determined separately for those areas, where no transition altitude has been specified.
3.2. Except as provided in para 3.3 the lowest usable flight level shall not be positioned below 1500 M (5000 FT) within the Finnish flight information region.
3.3. However, West of the longitude 22° E, within the responsibility area of ACC Finland sector J, the lowest usable flight level shall not be below the altitude 1850 M (6000 FT) MSL.

4 ALTIMETER SETTING ON GLIDER
FLIGHTS

The altimeter setting value 1013.2 HPA shall be used on all glider flights above the altitude of 1500 M (5000 FT).

5 CRUISING LEVELS

5.1. On en route flights in Finnish flight information region the semicircular system of cruising levels based on magnetic tracks is applied in accordance with the table below.
5.2. The following cruising levels shall be applied in the Finnish airspace:
 
Magneettinen lentosuunta / Magnetic track
000° - 179° 180° - 359°
IFR-lennot / IFR flights VFR-lennot / VFR flights IFR-lennot / IFR flights VFR-lennot / VFR flights

5.3. However, the correlation of levels to track shall not apply, when otherwise
  1.  specified in AIP ATS route table (ENR 3.2, column 3); or
  2.  indicated in air traffic control clearance:
5.4. VFR flights in level cruising flight at or above either 1500 M (5000 FT) from the mean sea level or 900 M (3000 FT) from ground or water, whichever is higher, and above this level shall be conducted at a flight level appropriate to the tracks as specified in column "VFR flights".
These provisions do not apply to non-power driven aircraft and in cases when otherwise instructed in the ATC clearance or prescribed by the Finnish Transport and Communications Agency.
