1 in 60 Rule

by [OFS] Gosling (en) / Jerry - Sunday, 27 March 2022, 11:32 AM
 

This is a method of assessing distance between diverging (or converging) tracks.  

For every degree difference between two tracks there is a 1 nautical mile separation after 60 nautical miles of travel.  

E.g. If a track is flown 5˚ Off heading, after 12 nautical miles there will be 1 nm separation.  

This only works up to about 15˚ of track separation.

3 OFFs

Bearing Off, Distance Off, Time Off

A method of checking leg tracking and timing at the mid leg check point during navigation

BEARING OFF - At your mid leg check point assess your location compared to the check point and estimate the difference in bearing from the start waypoint.  

DISTANCE OFF - Estimate the Distance Off of track using the 1 in 60 Rule.  

TIME OFF - Note hoe the time abeam the check point compares to the planned time

From these three Offs the aircraft can be flown back onto track or flown directly to the end leg waypoint.  Also an assessment of the time of arrival at the leg end waypoint can be made or the aircraft speed changed to maintain a time over the waypoint.

9-line

by [OFS] kaltokri / Rolf - Wednesday, 6 January 2021, 3:11 PM
 

Ein FAC (bzw. JTAC) teilt einem Piloten beim einem CAS-Einsatz mit, wann, wo und mit welcher Waffe angegriffen werden soll. Die Stellung befreundeter Einheiten, An- und Abflug, Zielposition und -beschreibung usw. muss in kurzer Zeit effektiv und möglichst unmissverständlich kommuniziert werden.

Dafür wurde ein Standard-Verfahren eingeführt, welches als 9-Line bezeichnet wird, weil die Informationen in neuen Zeilen übergeben werden.
