The runway All areas on an airport where aircraft move Runways and taxiways Runways, taxiways and apron 7 What is the airspace served by an approach unit normally referred to? Terminal area (TMA) Traffic information area (TIA) Flight information region (FIR) Control zone (CTR) 8 Which specialized agency is the regulator within aviation on a global level? IATA EASA ICAO ECAC 9 What is the objective of flight information service? Provide search and rescue assistance Prevent collision between aircraft in flight Provide information useful for the safe and efficient conduct of flights Provide pre-flight information for pilot planning purposes 10 What is an AIRAC cycle? Fixed cycles for updating SARPS documentation Fixed cycles for updating of AIP information A NOTAM serie A flight plan processing cycle 11 Which unit is the frequency of an electromagnetic wave? Hz Volt AM Lambda - λ 12 How is the relationship between wavelength and frequency? The shorter the wavelength, the lower the frequency There is no relationship between wavelength and frequency The shorter the wavelength, the higher the frequency The longer the wavelength, the higher the frequency 13 What is meant by multiplexing? A method to varying one or more properties of an electromagnetic wave to convey a message to it A method to transmit a digital signal as a periodic waveform A method by which multiple signals or digital data streams are combined into one signal over a shared medium. A method to convert an analogue signal into a digital signal 14 What is the main propagation mode of a VHF transmission? Groundwaves Sky-waves and groundwaves Sky-waves Direct/line of sight 15 What is the functionality with CPDLC? Communication between a controller and a pilot using data link Communication between controllers in different sectors Communication between a controller and a pilot using designated VHF voice frequencies A selective calling system that allows a ground operator to alert the aircrew 16 For how long time must voice recordings be stored? At least 30 days At least 30 hours At least 30 months At least 3 months 17 What is CIDIN? A transport layer for the aeronautical fixed telecommunication system An IP-based communication tool for surveillance data A communication system between controller and aircraft using data link A VoIP protocol for voice communication 18 What is OLDI? A system for communication between a controller and a pilot using data link A system to distribute aeronautical information A system to distribute surveillance data A system for coordination of flights between ATCC units Question #19 The angle between True North and Magnetic North is known as: Variation Correlation Drift Undulation 20 What is meant by accuracy in relation to navigational performance? The ability of a navigational system to continue operation even if maintenance requirements are not fulfilled. The difference between the estimated position and true position under fault free conditions The ability of the navigation system to provide its service without interruption during an operation The ability to provide timely warnings when the system is not safe to use 21
