MIDTERM NOTES AMGT 313 Phonetic numbers have three main uses: Clarity: They make sure that numbers sound RADIO COMMUNICATIONS different from each other, which helps avoid RADIOTELEPHONY - Provides the means by mistakes. which pilots of aircraft and ground personnel Uniformity: Everyone uses the same words for communicate with each other. numbers, so there's no confusion. Accuracy: They help people understand PHONETIC ALPHABET- The English language is numbers correctly, even when it’s hard to hear. recommended by the international civil aviation For example, imagine a pilot trying to land a organization (ICAO) for international air/ground plane in a storm. They need to listen to numbers communication. When you identify your aircraft from the control tower to know how high to fly. during initial contact with ATC or other facilities, If they mishear a number, it could be dangerous. you will use the phonetic alphabet as a routine But with phonetic numbers, they can measure which ICAO has adopted. understand clearly, even in a storm!

No communication, equipment and pilot qualification requirements.  2 TYPES OF RADAR EMERGENCY LOCATOR TRANSMITTER 1. PRIMARY RADAR - a ground-based system used When activated manually - or automatically by by ATC which transmits radio waves in a narrow immersion in water or as a result of high 'G' beam by a rotating antenna. forces on impact ELTs transmit a distress signal ▪ ADVANTAGES - Operates totally which can be detected by non-geostationary independently of that target aircraft. satellites and then located precisely by either or ▪ DISADVANTAGES - Enormous amounts of both of GPS trilateration and doppler power must be radiated to ensure returns triangulation. from the target. -Returns may be easily Requires the inspection of ELT within 12 calendar disrupted due to such factors as changes of months after proper installation, battery target attitude due to heavy rain. corrosion, operation of controls and crash sensor 2. SECONDARY RADAR - is cooperative because it and presence of sufficient signal from its requires the transponder on board the aircraft. antenna. Consist of a receiver and a transmitter. FLIGHT SERVICE STATION (FSS) DECODER (GROUND EQUIPMENT) An air traffic facility that provides information Enables a controller to assign a discrete and services to aircraft pilots before, during and transponder code to your aircraft. after flights, unlike air traffic control (ATC), is not To responsible for giving instructions or clearances normally, only one code will be assigned by or providing separation. They do, however, relay the computer for your entire flight. clearances from ATC for departure or approaches. INTERROGATION (SIGNAL) ▪ Transmit a coded signal from the computer VERY HIGH FREQUENCY (VHF) RADIO to your aircraft's transponder. Uses electromagnetic waves on the radio frequency range, for broadcasting two- way TRANSPONDER (REPLY) communication. The coded signal will be analyzed by the transponder and in turn, the transponder PUSH TO TALK BUTTON (PTT) automatically replies a specific coded signal. Used to transmit information by pushing the AZIMUTH button and talk. o Refers to the angle of aircraft from radar site is determined by the position of rotating antenna when reflected portion of radio wave is received. TRANSPONDER MODES 1. MODE A - Provides a 4-digit identification code for the aircraft set in the cockpit but assigned by the controller. 2. MODE C - Enables the radar to see aircraft altitude or flight level automatically when transponder is set to alt. More advanced than mode A 3. MODE S - Provides multiple information formats to a selective interrogation and is more advance than mode C. AVIATE NAVIGATE COMMUNICATE 4 W's of COMMUNICATION 1. WHO AM I CALLING? 2. WHO AM I? 3.
