2 BASIC ALTIMETER SETTING PROCEDURES
2.2 Altimeter Setting Procedures — New Zealand FIR
2.2.1 Within the New Zealand FIR the pilot of an aircraft operating:
- (a) at or above the transition level of FL150 must maintain vertical position by reference to the standard pressure value of 1013.2 hPa; and
- (b) at or below the transition altitude of 13,000 ft must maintain vertical position by reference to the QNH altimeter setting; and
- (c) between 13,000 ft and the transition level of FL150 must maintain vertical position by reference to the altimeter setting as advised by ATC.
2.2.2 The pilot of an aircraft must:
- (a) when climbing above 13,000 ft, set the altimeter to 1013.2 hPa; and
- (b) when descending through FL150, set the altimeter to the appropriate zone area or aerodrome QNH.
2.2.3 The transition layer, between 13,000 ft and FL150, can only be used for ascending or descending, or for cruising provided the aircraft has ATS approval.
2.2.4 Altimeter setting procedures are summarised in Figure 1.7-1.
