Note.- A GICB request (3.1.2.6.11.2) containing RR equals 16 and DI equals 7 and RRS equals 5 will cause the
resulting reply to contain the airborne position report in its MBfield.
3.1.2.8.6.3.1.1 SSS, surveillance status subfield in ME. The transponder shall report the surveillance status of the
transponder in this 2-bit (38, 39) subfield of ME when ME contains an airborne position squitter report.
Coding
0 signifies no status information
1 signifies transponder reporting permanent alert condition (3.1.2.6.10.1.1 .l)
2 signifies transponder reporting a temporary alert condition (3.1.2.6.10.1.1.2)
3 signifies transponder reporting SPI condition (3.1.2.6.10.1.3)
Codes 1 and 2 shall take precedence over code 3.
3.1.2.8.6.3.1.2 ACS, altitude code silbfild in ME. Under control of ATS (3.1.2.8.6.3.1.3), the transponder shall report
either navigation-derived altitude, or the barometric altitude code in this 12-bit (41-52) subfield of ME when ME contains
an airborne position report. When barometric altitude is reported, the contents of the ACS shall be as specified for the 13-
bit AC field (3.1.2.6.5.4) except that the M-bit (bit 26) shall be omitted.
3.1.2.8.6.3.1.3 Control of ACS reporting. Transponder reporting of altitude data in ACS s11all depend on the altitude
type subfield (ATS) as specified in 3.1.2.8.6.8.2. Transponder insertion of barometric altitude data in ACS shall be
inhibited when ATS has the value 1.
3.1.2.8.6.3.2 Surface position squittel: The surface position extended squitter type shall use format DF = 17 with the
contents of GICB register 06 {HEX) inserted in the ME field.
Note.- A GICB request (3.1.2.6.11.2) containin,g RR equals 16 and DI eqzials 7 and RRS equals 6 will cause the
resulting reply to contuin the surface position report in its MB field.
3.1.2.8.6.3.3 Aircruft idenfiflcation squitter: The aircraft identification extended squitter type shall use format DF = 17
with the contents of GICB rcgister 08 {HEX} instfled in the ME field.
Note.- A GICB reqnest (3.1.2.6.11.21 containing RR equals I6 and DI equals 7 and RRS equals 8 will cause the
resulting reply to contain tlze aircraj? identi-ficution mport in its MB field.
3.1.2.8.6.3.4 Airborne velocity squittelr The airborne velocity extended squitter type shall use format DF =, 17 with
the contents of GICB register 09 {HEX) inserted in the ME field.
Note.- A GICB request (3.1.2.6.11.2) containing RR equals 16 and DI equals 7 and RRS equals 9 will cause the
resulting reply to contain the airborne velocity report in its MB field.
3.1.2.8.6.3.5 Event-driven squittel: The event-driven extended squitter type shall use format DF = 17 with the contents
of GICB register OA {HEX) inserted in the ME field.
Note.- A GICB request (3.1.2.6.11.2) containing RR equals 16 and DI equals 7 and RRS equals 10 wlll cause the
resulting reply to contuin the event-driven report in 1ts MB field.
Chapter 3 Annex 10 - Aeronautical Telecommunications
3.1.2.8.6.4 Exterzded sq~titterr ate
3.1.2.8.6.4.1 Xnitialization. At power up initialization, the transponder shall commence operation in a mode in which
it broadcasts only acquisition squitters (3.1.2.8.5). The transponder shall initiate the broadcast of extended squitters for
airborne position, surface position, airborne velocity and aircraft identification when data are inserted into transponder
registers 05, 06, 09 and 08 {HEX), respectively. This determination shall be made individually for each squitter type.
When extended squitters are broadcast, transmission rates shall be as indicated in the following paragraphs. Acquisition
squitters shall be reported in addition to extended squitters unless the acquisition squitter is inhibited (2.1.5.4). Acquisition
squitters shall always be reported if position or velocity extended squitters are not reporled.
Note 1.- This suppresses the transmission of extended squitrers from aircraft thut are unable to report position, velocity
or identity. If input to the register for a squitter type stops for 60 seconds, broadcast of that extended squitter type will be
discontinued until data insertion is resumed.
Note 2.- After timeout (3.1.2.8.6.6), this squirter type may contain an MEfield of all zeroes.
3.1.2.8.6.4.2 Airborne positiorz squitter rate. Airborne position squitter transmissions shall be emitted when the
aircraft is airborne (3.1.2.8.6.7) at random intervals that are uniformly distributed over the range from 0.4 to 0.6 seconds
using a time quantization of no greater than 15 milliseconds relative to the previous airborne position squitter, with the
exceptions as specified in 3.1.2.8.6.4.7.
3.1.2.8.6.4.3 Surface position squitter rate. Surface position squitter transmissions shall be emitted when the airr,raft
is on the surface (3.1.2.8.6.7) using one of two rates depending upon whether the high or low squitter rate has been
