\item Notes: Paired amounts follow the source aircraft categories. Nanshan amounts come from the checksum-verified official operation-procedure DOC and its archived UTF-8 extraction. ``Noise safeguard'' records an ex-post eligibility clause, not a continuous payment adjustment. ``Exp. term'' indicates whether a named exposure measure changes the positive reward amount.
