A-5) Item 10 requires the use of ‘N’ if no COM/NAV/approach aid equipment is carried, or ‘S’ if standard COM/NAV/approach aid equipment is carried. However the example given at the end of Item 10 does not include N or S, see below: Is there a number of characters limitation on this field that, when reached, results in dropping the first character – or should the S or N always be included?

 

Example: ADE3RV/HB2U2V2G1

 

The S or N will always be used when they are required to inform the recipient of Standard or NO COM/NAV equipment. The example describes a specific situation where S or N do not apply. Regarding the limitation on the length of the Item, see A-1.
