It's in the AIP (Air Services Website) Section ENR 1.7 ALTIMETER SETTING PROCEDURES http://www.airservices.gov.au/publications/current/aip/enr/1_7_1-4.pdf

Hello all. Can any of you IFR gurus point me the CASA reference which requires IFR pilots to check the accuracy of altimeters prior to takeoff? I think I recall the figure as 70 feet but just reading up on some IFR notes and wanted to check. I can't find it anywhere. Cheers. -- Posted at www.Usenet.com.au
