[. . . ] Mode S functions include the following features: · Level-2 reply data link capability (used to exchange information between aircraft and various ATC facilities) · Surveillance identifier capability · Flight ID reporting · Altitude reporting · Airborne status determination · Transponder capability reporting · Mode S Enhanced Surveillance (EHS) requirements · Acquisition squitter Flight ID Reporting ­ The G1000 transponder reports aircraft identification as either the aircraft registration or a FLT ID (Flight Identification). The system is configured for either option by an authorized Garmin service center. If configured for Flight ID entry, the pilot must enter the appropriate flight ID on the PFD. After the correct Flight ID is entered, the aircraft identification reported in response to ATC radar interrogations is properly correlated with the associated call sign for voice communication. [. . . ] The flight ID is not to exceed seven (7) characters. No space is needed when entering Flight ID. When a Flight ID contains a space, the system automatically removes it upon completion of Flight ID entry. (See ICAO documents 8168, 4444 and 8585 for further details). If the Flight ID is set to `SAME AS TAIL' no entry is required. In this configuration, the transponder then reports the aircraft registration number to ATC. Acquisition Squitter ­ Acquisition squitter, or short squitter, is the transponder 24-bit identification address. The transmission is sent periodically, regardless of the presence of interrogations. The purpose of acquisition squitter is to enable Mode S ground stations and Traffic Collision Avoidance System (TCAS) equipped aircraft to recognize the presence of Mode S-equipped aircraft for selective interrogation. TRAFFIC INFORMATION SERVICE (TIS) Mode S provides a data link for Traffic Information Service (TIS). TIS is a ground-based service that sends out location, direction, altitude and climb/descent information relative to all transponder-equipped aircraft within a radius of 55 miles from select sites. For aircraft not equipped with TCAS or TAS, TIS provides a graphic display of traffic information. Five seconds after the fourth digit has been entered, the transponder code becomes active. Figure 5. 2. 4 Altitude Mode 3. Reply Status When the transponder sends replies to interrogations, an R indication appears momentarily in the reply status field of the Transponder Status bar. Figure 5. 2. 5 Reply Indication Figure 5. 2. 6 Entering a Code NOTE: When entering a code, press the BKSP (backspace) softkey to back up and change code digits. 5-4 Garmin G1000 Transponder Pilot's Guide 190-00382-00 Rev. D OPERATION VFR Code The VFR code can be entered either manually, each digit at a time, or by pressing the XPDR softkey, then the VFR softkey. When the VFR softkey is pressed, the preprogrammed VFR code is automatically displayed in the code field of the Transponder Status bar. Pressing the VFR softkey again restores the previous identification code. NOTE: The pre-programmed VFR code is set at the factory to 1200. IDENT FUNCTION Pressing the IDENT softkey sends an ID indication to Air Traffic Control (ATC). The ID return distinguishes your transponder from all others on the air traffic controller's radar screen. The IDENT softkey appears in all levels of transponder softkeys. When the IDENT softkey is pressed, a green IDENT indication is displayed in the mode field of the Transponder Status bar for a duration of 18 seconds. Important Codes Following is a list of important codes: · 1200 ­ VFR code in the U. S. (refer to ICAO standards for VFR codes in other countries). · 7000 ­ VFR code commonly used in Europe (refer to ICAO standards). · 7600 ­ Loss of communication code. [. . . ] · 7000 ­ VFR code commonly used in Europe (refer to ICAO standards). · 7600 ­ Loss of communication code. · 7777 ­ Military interceptor operations code (NEVER SQUAWK THIS CODE). · 0000 ­ Code for military use in the U. S. Figure 5. 2. 7 IDENT Indication When the IDENT softkey is pressed while in Mode or Code Selection, the system reverts to the Top-level softkeys. NOTE: In Standby mode, the IDENT softkey is inoperative. 190-00382-00 Rev. [. . . ]
