1. Introduction
The altimeter setting procedures in use conform to those published in ICAO Doc 8168 Vol. I (PANS OPS), Part III, Section 1, and are depicted below.
Transition altitudes are depicted on the relevant instrument approach charts only.
QNH reports and temperature information for use in determining adequate terrain clearance are provided in MET broadcasts and are also available from the air traffic services units. QNH values are given in hectopascals.
2. Basic altimeter setting procedure
2.1 General
2.1.1 Transition altitude within Tel-Aviv FIR is 18,000 ft. Transition level is at FL200.
2.1.2 When flying over land below FL330 Aircraft shall remain under regional QNH.
2.2 Take-off and climb
2.2.1 A QNH altimeter setting is made available by ATIS and by ATC prior to take-off.
2.2.2 Vertical positioning of aircraft during climb is expressed in terms of altitude until reaching the transition altitude, above which vertical positioning is expressed in terms of flight level.
2.3 En-route
2.3.1 Vertical separation during en-route phase of flight shall be expressed in terms of flight level, except while flying over land below FL350 FL330 (in such case vertical separation shall be expressed in terms of altitude according to QNH which will be provided by ATC).
2.4 Approach and landing
2.4.1 A QNH altimeter setting is made available by ATIS, ACC and in the approach clearance.
2.4.2 Aircraft arriving to Tel-Aviv FIR from the west shall set their altimeter so that the vertical position of the aircraft will be expressed in terms of altitude when descending through FL200, or when crossing the coastline, whichever earliest.
2.4.3 Aircraft arriving to Tel-Aviv FIR from the east shall set their altimeter so that the vertical position of the aircraft will be expressed in terms of altitude when crossing the FIR boundary
2.4.4 Aircraft arriving to Tel-Aviv FIR from the south shall set their altimeter so that the vertical position of the aircraft will be expressed in terms of altitude at "NURIT".
