Fifteenth Edition - 2007
NOTE 1: standard equipment is taken into account to be VHF RTF, ADF, VOR and ILS, unless another combination is prescribed by the appropriate ATS authority.
NOTE 2: If the letter Z is utilized, specify in Item 18 the other equipment carried, preceded by COM/ and/or NAV/, as appropriate.
NOTE 3: If the letter J is utilized, specify in Item 18 the equipment carried, preceded by DAT/ followed by one or more letters as appropriate.
NOTE 4: Info on navigation capability is provided to ATC for clearance and routing purposes.
NOTE 5: Inclusion of R indicates that an airplane meets the RNP type prescribed for the route segment(s), route(s) and/or area involved.
– Surveillance Equipment (instruments):
A transponder — Mode A (4 digits — 4096 codes)
C transponder — Mode A (4 digits — 4096 codes) and Mode C
X transponder — Mode S without both airplane identification and pressure-altitude transmission
P electrical device — Mode S, together with pressure-altitude transmission, however no airplane identification transmission
I electrical device — Mode S, together with the airplane identification transmission, however no pressure-altitude transmission
S electrical device — Mode S, together with both pressure-altitude and airplane identification transmission.
D ADS capability
EET/ significant points or FIR boundary designators and accumulated estimated elapsed times to such points or FIR boundaries, when thus prescribed on the basis of regional air navigation agreements, or by the appropriate ATS authority.
RIF/ The route details to the revised destination airfield, followed by the International Civil Aviation Organization four-letter location indicator of the airfield. The revised route is subject to re-clearance in flight.
REG/ The registration markings of the airplane, if completely different from the airplane identification in Item seven (7).
SEL/ SELCAL Code, if so prescribed by the appropriate ATS authority.
OPR/ Name of the operator, if not obvious from the airplane identification in Item seven (7).

PER/ airplane performance data, if so prescribed by the appropriate ATS authority.
COM/ important information related to communication equipment as required by the appropriate ATS authority; e.g., COM/UHF only.
DAT/ important information associated with data link capability, using one or more of the letters S, H, V and M; e.g., DAT/S for satellite data link; DAT/H for HF data link; DAT/V for VHF data link; DAT/M for SSR Mode S data link.
NAV/ significant data related to navigation equipment as required by the appropriate ATS authority.
DEP/ Name of departure airfield, if ZZZZ is inserted in Item thirteen (13), or the International Civil Aviation Organization four letter location indicator of the location of the ATS unit from which supplementary flight plan data may be obtained, if AFIL is inserted in Item thirteen (13).
DEST/ Name of destination airfield, if ZZZZ is inserted in Item sixteen (16).
ALTN/ Name of destination alternate aerodrome(s), if ZZZZ is inserted in Item sixteen (16).
RALT/ Name of en-route alternate aerodrome(s).
CODE/ airplane address (expressed in the form of an alphanumerical code of six hexadecimal characters) when required by the appropriate ATS authority.
RMK/ any other plain language remarks when needed by the appropriate ATS authority or deemed necessary.
