This phraseology is giving you examples of Air Traffic Control (ATC) for the use by Special Operations on IVAO. In some occasions it can be used for civilian purposes as well. This may and can be use by overall ATC between pilots and controller on IVAO network. This will show you in complete text examples how voice communications goes around the globe.
In this example you are able to find : - Common information - Basic, Standard and Advanced - Used terms - Emergency procedures - Radio communication Common Within the overall aviation world, communication is a very essential part of it. Communication must be used to let all aircraft fly through the skies without any problems. Pilots and ATC must use communication from the beginning until the end. Without communication the skies above us would be one big mess. That’s also what we on IVAO don’t want to create. Language: Within aviation the language English is being used only. It’s also permitted to use own language as a pilot or ATC only, when some big misunderstandings take place. (To fellow country members only) English language must be maintained and present at all times. Transmission: To transmit a message as a pilot to ATC or as ATC to a pilot there are some things you need to keep in mind before transmitting. * Before transmitting a message, listen first carefully to the frequency. You don’t want to interfere with others. * Now how to handle your microphone and teamspeak. * Use a normal transmission mode. Speak clearly and slowly. This way you are better to understand. * Maintain a constant transmission speed. Don’t shout and change your speed of talking. * Incase of an emergency, stay calm. Don’t start yelling and doing all crazy. * Use short breaks between numbers when transmitting. This way confusions don’t have to occur. * Push your transmission button before starting to talk. Let is go after you finished. * Never use voice activation for teamspeak. This way you can interfere without any idea. When you transmitted a message and made a mistake, always use the term “correction “to correct you message to the own you are transmitting to. The best way to give your correction, you could transmit the message again. Now you can use “correction, I say again “ Priority: Transmissions that begin with emergency calls are always first! “PAN-PAN-PAN “: Indicates something has goes wrong. Not a emergency call yet. “MADAY-MAYDAY-MAYDAY “: Indicates a emergency in progress. Readability: When a transmission is not clearly, or is clear you can use “Unreadable, Say Again, Loud en Clear. Example: Reading you loud and clear with some background noise.
Use of term “Cleared “: Can only be used by the following options * Cleared ILS approach * Cleared for *** departure route * Cleared for take-off The word take-off may only be used it a aircraft is really cleared to. Otherwise use the word departure. Authorization to flight routes such as airways, altitudes and intersections are used with the term “Cleared to/off “ To use the “cleared to “term can also be applied by: * Cleared to cross runway * Cleared to land * Cleared for tough and go. Never use the term “cleared to/for “by the following: * Start-up (start-up approved) * Crossing a runway (Crossing approved) * Taxi (taxi to ....) * Exit runway (vacated rwy ) ATC may also never use clear to incase of climb or descent ATC shall use “ climb to and descent to “ Example : (ATC) KLM123 descent to FL100 ... (Pilot) KLM123 leaving FL150, descending to FL100 Also when a heading is given you must use the word “ heading ” before it. Example : KLM123 turn right heading 240. What you hear a lot is KLM123 turn right 240. Some pilots may understand this as heading 40. Issuance of a clearance : * (aircraft) cleared to ... * Recleared (amended clearance details)
* Recleared (amended route portion) TO * Enter control area or zone via (significant point) at (level) at (time)
* Leave control area or zone at (level) * Join (specify) at (significant point) at (level) at (time) Indication of route and clearance limit : A. From (place) to (place) b. To (place) followed as necessary by : * Direct * Via (route and/or reporting points); * Via flight plan route * Via (distance) arc (direction) or (name of DME station) * Out of control area or zone (distance) (direction) or (place) Maintenance of specified levels : * Maintain (level) to (significant point). * Maintain (level) until passing (significant point). * Maintain (level) until (time). * Maintain (level) until advised by (name of unit). * Maintain (level) until further advice. * Maintain (level) while in controlled airspace. * Maintain at least (number) feet (or meters) above or below (aircraft identification).
The term 'MAINTAIN' is not be used in
lines of descend or climb when instructing an aircraft Specification of cruising levels : * Cross (significant point) at (or above, or below) (level). * Cross (significant point) at (time) or later(or before) at (level) (maintain own separation and VMC). * Cruise climb between (levels) (or above) (level). * Cross (distance) (name of DME station) DME at (or above, or below) (level). Emergency descent : * Emergency descend (intentions) * Emergency descent at (significant point or location) all aircraft below (level) within (distance) of (significant point or navigation aid) leave immediately (followed as necessary by specific instructions as to direction, heading or track, etc.).
