Victor airways exist below 18000' and are defined by VOR radials. For these airways, state the word “victor” followed by the airway number in group form. For example:
Jet airways exist between FL180 and FL450. For these airways state the letter “J” followed by the airway number in group form (in this case, the phonetic pronunciation for the letter “J” is not used). For example:
High altitude RNAV airways are identified by the letter “Q”, Low altitude RNAV airways are identified by the letter “T.” For “Q” airways, state the letter “Q” followed by the airway number in group form. For “T” airways, state the letter of the route phonetically, followed by the number of the route in group form. For example:
ZLA routinely deals with oceanic routes. There are several published routes west of LAX that connect aircraft to oceanic routes. These are all depicted in the sector file and on high altitude IFR charts. These aren't traditional airways since they exist in international airspace. For example, Control 1176 connects RZS VOR to DINTY intersection. These airways are useful because they keep aircraft clear of the warning areas offshore.
Once aircraft enter oceanic airspace, there are lettered routes. ZLA is affected by "R", "B", and "G" routes. Each of these can be found in the sector file by displaying "high airways." These airways all begin at ZLA's western boundary. When issuing routes with these types of airways, state the letter phonetically, followed by the number of the route in group form.
Here are some examples of how to use oceanic airways:
