The eventual update of this type of event shall be encoded following the general rules for {{Event updates or cancellation}}, which provide instructions for all NOTAM fields, except for item E and the condition part of the Q code, in the case of a NOTAM C
...
The following pattern should be used for automatically generating the E field text from the AIXM data:
EBNF Code
| Code Block | ||||
|---|---|---|---|---|

template_cancel = ["(1)" "AHP.BL.type (2)" ("AHP.BL.name (3a)" | "AHP.BL.ARP (3b)")] ( "(4)" "ALS RWY" "RDN.BL.designator" {"/" "RDN.BL.designator"} | "(5)" "RWY" "RLS.TD.position" {"AND" "RLS.TD.position"} "LIGHTS" "RDN.BL.designator" {"/" "RDN.BL.designator"} | "(6)" "TWY" "TWL.TD.position" {"AND" "TWL.TD.position"} "TWY.BL.designator" {"," "TWY.BL.designator"} | "(7)" "VGI.TD.type" "RDN.BL.designator" {"/" "RDN.BL.designator"}) \n
[("resumed normal operations."] | [" : New NOTAM to follow. (10)"] "." \n). |
| Reference | Rule |
|---|---|
| (11) | If the NOTAM will be followed by a new NOTAM concerning the same situation, then the operator shall have the possibility to specify "New NOTAM to follow" and this text shall be appended at the end of item E of the NOTAM C. Note: in this case, the 4th and 5th letters of the Q code shall also be changed into “XX” |
