YOUR ENTIRE FLIGHT. INTERROGATION (SIGNAL) TRANSMIT A CODED SIGNAL FROM THE COMPUTER TO YOUR AIRCRAFT’S TRANSPONDER. TRANSPONDER (REPLY) THE CODED SIGNAL WILL BE ANALYZED BY THE TRANSPONDER AND IN TURN, THE TRANSPONDER AUTOMATICALLY REPLIES A SPECIFIC CODED SIGNAL. THE ATC NOW CAN FIND THE AIRCRAFT ON THE RADAR SCREEN COMPUTER.  TRANSPONDER MODES MODE A : SOMETIMES REFFERED TO AS MODE 3/A, TRANSMIT AN IDENTIFYING CODE ONLY. MODE C : ENABLES THE RADAR TO SEE AIRCRAFT ALTITUDE OR FLIGHT LEVEL AUTOMATICALLY WHEN TRANSPONDER IS SET TO ALT. MORE ADVANCED THAN MODE A. MODE S : HAS ALTITUDE CAPABILITY AND PERMITS DATA EXCHANGE. IT IS MORE ADVANCE THAN MODE C. TRANSPONDER OPERATION SQUAWK – IS USED BY THE CONTROLLER TO ASSIGN YOUR AIRCRAFT CODE, AS WELL AS TO INDICATE WHICH TRANSPONDER FUNCTION YOU SHOULD SELECT. OFF, SBY (STANDBY), ON, ALT (ALTITUDE), AND TST (TEST).  TRANSPONDER PHRASEOLOGY SQUAWK (NUMBER). SQUAWK STANDBY. SQUAWK ALTITUDE. STOP ALTITUDE SQUAWK. IDENT. SQUAWK NUMBER AND IDENT. STOP SQUAWK. SQUAWK MAYDAY ON 7700. SQUAWK VFR. TRANSPONDER SPECIAL CODES TRANSPONDER CAN HAVE A TOTAL 4096 COMBINATION OF NUMBERS. 1200 – VFR CODE 7500 – HIJACKED 7600 – FAILURE OF 2 WAY RADIO COMMUNICATION. 7700 – OTHER EMERGENCIES. HOW TO USE YOUR TRANSPONDER PRIOR TO TAXI, SET TRANSPONDER TO STANDBY. HOW TO USE YOUR TRANSPONDER SET TRANSPONDER TO ON PRIOR TAKE-OFF, IF USING MODE A. IF MODE C AUTOMATIC ALTITUDE REPORTING EQUIPMENT SET TO ALT PRIOR TO TAKE-OFF. HOW TO USE YOUR TRANSPONDER WHEN MAKING INITIAL CALL WITH ATC PRIOR ENTERING AIRSPACE, STATE ALTITUDETO NEAREST 100 FEET. EXAMPLE: YOUR ALTITUDE IS 7450, SAY “7500”. IF YOU DO NOT STATE ALTITUDE, THEY COULD POSSIBLY SAY “VERIFY AT 7500” (SHOWN IN RADAR). HOW TO USE YOUR TRANSPONDER AFTER LANDING, SWITCH TRANSPONDER TO STANDBY OR OFF AS SOON AS PRACTICAL.  RADAR TRAFFIC ADVISORIES THEY ALSO PROVIDE SAFETY ALERTS, TRAFFIC ADVISORIES, LIMITED VECTORING. TRAFFIC IS REFERENCED BY AZIMUTH FROM AIRCRAFT IN TERMS OF THE 12-HOUR CLOCK. DISTANCE IN NAUTICAL MILES, DIRECTION IN WHICH THE TARGET IS MOVING, TYPE AND ALTITUDE OF THE AIRCRAFT. EXAMPLE: “TRAFFIC 2 O’CLOCK, 5 MILES EAST BOUND, CESSNA 152, 3000 FEET.  SAFETY ALERTS RECEIVE THIS IF YOU ARE UNSAFE PROXIMITY TO TERRAIN, OBSTRUCTIONS, OR ANOTHER AIRCRAFT. “LOW ALTITUDE ALERT, CHECK ALTITUDE IMMEDIATELY.” “TRAFFIC ALERT, ADVISE YOU TURN RIGHT, HEADING 090 OR CLIMB 8000 IMMEDIATELY.” VHF/DF (DIRECTION FINDER) AN FSS SPECIALIST MAY BE ABLE TO LOCATE YOUR AIRCRAFT WITH AN OPERATIONAL VHF TRANSMITTER. THE FSS WILL ASK YOU TO KEY YOUR MICROPHONE WHILE THE DIRECTION-FINDING EQUIPMENT HOMES IN ON YOUR RADIO SIGNAL. VOR’s, ADF’s, etc. VHF COMMUNICATION EQUIPMENT OPERATES ON A PORTION OF THE VHF RANGE, TWO WHICH CLASSIFICATION INCLUDES OF CHANNELS FREQUENCIES FROM 118.0 MHz – 135.975 MHz. 360-CHANNEL 720-CHANNEL RADIO – USES 50 RADIO – USES 25 KHz SPACING KHz SPACING  ATIS – AUTOMATIC TERMINAL INFORMATION SERVICE ATIS TIME OF AIRPORT PHOENETIC RUNWAY IN DEPARTURE CURRENT W/X NAME LETTER USE FREQUENCY REPORT IDENTIFIER MAGNETIC VISIBILITY, WIND TEMPERATUE , ALTIMETER CEILING, SKY REMARKS DIRECTION DEWPOINT SETTING CONDITION AND VELOCITY
