ALTIMETER CORRECTIONS

Extracted from ICAO Document 8186; Vol I; Part VI; Chapter 3 – ALTIMETER SETTING PROCEDURES.

Note:

This chapter deals with altimeter corrections for pressure, temperature and, where appropriate, wind and terrain effects. The pilot is responsible for thesecorrections except when under radar vectoring. In that case, the radar controller shall issue clearances such that the prescribed obstacle clearance willexist at all times, taking the cold temperature correction into account.

PRESSURE CORRECTION

Flight Levels

When flying at levels with the altimeter set to 1013.2 hPa, the minimum safe altitude must be corrected for deviations in pressure when the pressure is lowerthan the standard atmosphere (1013 hPa). An appropriate correction is 10m (30 ft) per hPa below 1013 hPa. Alternatively, the correction can be obtainedfrom standard correction graphs or tables supplied by the operator.

QNH/QFE

When using the QNH or QFE altimeter setting (giving altitude or height above QFE datum respectively), a pressure correction is not required.

TEMPERATURE CORRECTION

Requirement for Temperature Correction

The calculated minimum safe altitudes/heights must be adjusted when the ambient temperature on the surface is much lower than that predicted by thestandard atmosphere. In such conditions, an approximate correction is 4 per cent height increase for every 10° C below standard temperature as measuredat the altimeter setting source. This is safe for all altimeter setting source altitudes for temperatures above -15°.

Tabulated Corrections

For colder temperatures, a more accurate correction should be obtained from Tables 1 and 2 below. These tables are calculated for a sea level aerodrome.They are therefore conservative when applied at higher aerodromes.

Note 1:

The corrections have been rounded up to the next 5m or 10 ft increment.

Note 2:

Temperature values from the reporting station (normally the aerodrome) nearest to the position of the aircraft should be used.
