ENR 1.7 ALTIMETER SETTING PROCEDURES
1. PRE-FLIGHT ALTIMETER CHECK
1.1 General
1.1.1 Whenever an accurate QNH is available and the aircraft is at a
known elevation, pilots must conduct an accuracy check of the aircraft
altimeter(s) at some point prior to take-off. In order of priority,
the pilot should use tarmac, threshold or airfield reference point
elevation for the check.
Note: Where the first check indicates that an altimeter is unserviceable,
the pilot is permitted to conduct a further check at
another location on the same airfield; for example, the first on the
tarmac and the second at the runway threshold (to determine altimeter
serviceability).
1.2 IFR Altimeters
1.2.1 With an accurate QNH set, the altimeter(s) should read the nominated
elevation to within 60FT. If an altimeter has an error in excess
of ± 75FT, the altimeter must be considered unserviceable.
1.2.2 When two altimeters are required for the category of operation,
one of the altimeters must read the nominated elevation to within
60FT. When the remaining altimeter has an error between 60FT
and 75FT, flight under the IFR to the first point of landing, where the
accuracy of the altimeter can be re-checked, is approved. In the
event that the altimeter shows an error in excess of 60FT on the
second check, the altimeter must be considered unserviceable for
flight under the IFR.
1.2.3 An aircraft fitted with two altimeters but requiring only one for the
category of operation may continue to operate under the IFR provided
one altimeter reads the nominated elevation to within 60FT.
Should the remaining altimeter have an error in excess of 75FT
that altimeter must be placarded unserviceable and the maintenance
release appropriately endorsed.
1.2.4 When an aircraft is fitted with only one altimeter and that altimeter
has an error between 60FT and 75FT, flight under the IFR to the
first point of landing, where the accuracy of the altimeter can be
re-checked, is approved. In the event that the altimeter shows an

ENR (EN ROUTE) A/L 45 effective 24 NOV 05
error in excess of 60FT on the second check the altimeter is to be
considered unserviceable for flight under the IFR.
1.3 VFR Altimeters
1.3.1 With an accurate QNH set, a VFR altimeter(s) should read site
elevation to within 100FT (110FT at test sites above 3,300FT) to
be accepted as serviceable by the pilot. If an aircraft fitted with two
VFR altimeters continues to fly with one altimeter reading 100FT
(110FT) or more in error, the faulty altimeter must be placarded unserviceable
and the error noted in the maintenance release.
1.3.2 VFR altimeters are not permitted for aeroplane operations above
FL200. VFR flights operating above FL200 must be equipped with
an altimeter calibrated to IFR standards.
1.4 Accurate QNH and Site Elevation
1.4.1 A QNH can be considered accurate if it is provided by ATIS, Tower
or an automatic remote-reporting aerodrome sensor. Area or forecast
QNH must not be used for the test.
1.4.2 Site elevation must be derived from aerodrome survey data published
by Airservices or supplied by the aerodrome owner.
2. ALTIMETER SETTING RULES
2.1 Transition Layer, Altitude and Level
2.1.1 The system of altimetry used in Australia makes use of a transition
layer between the Transition Altitude which is always 10,000FT
and the Transition Level of FL110 to FL125 depending on QNH
(see Figure 1) to separate aircraft using QNH from those using
1013.2HPA as a datum.
2.1.2 For all operations at or below the Transition Altitude (in the Altimeter
Setting region), the altimeter reference setting will be:
a. the current Local QNH of a station along the route within
100NM of the aircraft; or
b. the current Area Forecast QNH if the current Local QNH is not
known.
2.1.3 For cruising in the Standard Pressure Region, the altimeter reference
must be 1013.2HPA.
2.1.4 The position to change between QNH and 1013.2HPA shall always
be in the Standard Pressure Region on climb after passing

10,000FT and prior to levelling off, or on descent to a level in the
Altimeter Setting Region prior to entering the Transition Layer and
is shown in Figure 1.
