Comment: addressing the APRON duplication in the encoding rules

Text NOTAM production rules

...

The following pattern should be used as a base for generating the E field text from the AIXM data:

Rule

(1)

If AHP.BL.locationIndicatorICAO=YES, then ignore this branch.

(2)

Insert here the type of the airport decoded as follows

AHP.BL.type

Text to be inserted in Item E

AD or AH

"AD"

HP

"Heliport"

LS or OTHER

"Landing site"

(3)

a. If AHP.BL.name is not NIL, then insert it here. Otherwise

b.insert here the text "located at" followed by the AHP.BL.ARP.ElevatedPoint decoded according to the text NOTAM production rules for aixm:Point.(4followed by the AHP.BL.ARP.ElevatedPoint decoded according to the text NOTAM production rules for aixm:Point.

(4)For the potential applications/implementations - the word "APRON" may appear twice depending on the coded APN.BL.name (e.g. APRON MILITARY APRON or APRON APRON A1). Caution shall be exercised for NOTAM production to avoid possible duplications.

(5)

If more than one apron has a TEMPDELTA associated with the Event, then insert the designator of each additional apron designator preceded by ",". Insert "and" before the last entry.

(56)

If there exists a APN.TD.availability.annotation having propertyName="operationalStatus" and purpose="REMARK", then translate it into free text according to the decoding rules for annotations.

(67)

If there exist one or more TD.availability.usage then decode them following this branch, in the following order of priorities:

  • TD.availability.usage that have operation="ALL"

  • TD.availability.usage that have type="PERMIT"

  • ... other situations ...

  • TD.availability.usage that have priorPermission which is not NIL shall be decoded last.

(78)

If TD.usage.priorPermission is not NIL, then insert here the decoding of the PPR information as detailed in the following diagram:

Code Block

collapsetrue
template_PPR = "PPR " "TWY/TWE.TD.usage.priorPermission(7.1)" ["TWY/TWE.TD.usage.annotation(7.2)"].

Reference

Rule
