Altitude Separation l Use The Bishop Altimeter (ASOS 119.025) l Common Reference Pressure Is Essential l North & South Pressures Could Be Very Different l Use The Bishop Altimeter (ASOS 119.025) l Common Reference Pressure Is Essential l North & South Pressures Could Be Very Different

15. February 200114 Procedure Alpha Part 2... continued... Make Disciplined Position Reports l Always When Within 2 – 3 nm of the Airspace l Only When Cruising... or l Just As You Start To Cruise l Always Over, or Near A Reference Point l Always When Within 2 – 3 nm of the Airspace l Only When Cruising... or l Just As You Start To Cruise l Always Over, or Near A Reference Point

16. February 200115 Procedure Alpha Part 2... continued... Format For Position Reports 1.Who You Are Calling (“White Mountain Traffic”) 2.Your Contest Number (Or Other Call Sign) 3.Your Direction of Flight (“Northbound” or “Southbound”) 4.Your Altitude 5.Your Position (Over or Near a Reference Point) 6.Your Direction of Flight (“Northbound” or “Southbound”) 1.Who You Are Calling (“White Mountain Traffic”) 2.Your Contest Number (Or Other Call Sign) 3.Your Direction of Flight (“Northbound” or “Southbound”) 4.Your Altitude 5.Your Position (Over or Near a Reference Point) 6.Your Direction of Flight (“Northbound” or “Southbound”)

17. February 200116 Procedure Alpha Part 2... continued... Example Position Reports l Northbound: “ White Mountain traffic, sky northbound, two point six miles north Mount Inyo, one six thousand four hundred, northbound” l Southbound : " White Mountain traffic, sierra echo southbound, three miles west of Waucoba Mountain, one seven thousand, six hundred, southbound” l Northbound: “ White Mountain traffic, sky northbound, two point six miles north Mount Inyo, one six thousand four hundred, northbound” l Southbound : " White Mountain traffic, sierra echo southbound, three miles west of Waucoba Mountain, one seven thousand, six hundred, southbound”
