Use the following techniques to the extent possible when you provide radar assistance to a pilot not qualified to operate in IFR conditions:Īvoid radio frequency changes except when necessary to provide a clear communications channel. The following must be accomplished on a Mode C equipped VFR aircraft which is in emergency but no longer requires the assignment of Code 7700: If the aircraft is below appropriate terrain/obstacle clearance minimum altitude and sufficiently accurate position information has been received or radar identification is established, furnish a heading or radial on which to climb to reach appropriate terrain/obstacle clearance minimum altitude. If the aircraft has already encountered IFR conditions, inform the pilot of the appropriate terrain/obstacle clearance minimum altitude. Refuses to declare an emergency and you have determined the exact nature of the radar services the pilot desires. If the action in subparagraph 1 above is not feasible or the pilot declines to conduct VFR flight to another airport, provide radar assistance if the pilot: Inform the pilot of airports where VFR conditions are reported, provide other available pertinent weather information, and ask if he/she will elect to conduct VFR flight to such an airport.If the pilot states he/she is not qualified for or not capable of conducting IFR flight, or if he/she refuses to file an IFR flight plan, take whichever of the following actions is appropriate: If the pilot states he/she is qualified for and capable of IFR flight, request him/her to file an IFR flight plan and then issue clearance to destination airport, as appropriate. If a VFR aircraft requests radar assistance when it encounters or is about to encounter IFR weather conditions, ask the pilot if he/she is qualified for and capable of conducting IFR flight. ![]() RADAR ASSISTANCE TO VFR AIRCRAFT IN WEATHER DIFFICULTY.An appropriate keyboard entry must be made to ensure en route MSAW (EMSAW) alarm processing. Assign a beacon code that will permit terminal minimum safe altitude warning ( MSAW) alarm processing. The following must be accomplished on a Mode C equipped VFR aircraft which is in emergency but no longer requires the assignment of Code 7700: If the aircraft is unable to communicate with the control facility, relay information and clearances. If a frequency change is necessary, advise the pilot of the reason for the change, and request the aircraft contact the appropriate control facility. ![]() If VFR aircraft requests assistance when it encounters or is about to encounter IFR weather conditions, determine the facility best able to provide service. Immediately inform the operations manager, supervisor or CIC. No reference to the hijacking must be made in subsequent communications unless initiated by the pilot, or unless directed by the DEN Air Traffic Security Coordinator. Should the pilot fail to acknowledge or communicate further, assume that the flight is being subject to hijack. (Identification)(name of facility) VERIFY SQUAWKING SEVEN FIVE ZERO ZERO. When you consider it necessary and if weather and circumstances permit, recommend that the aircraft maintain or increase altitude to improve communications or radar. Orientate an aircraft by the means most appropriate to the circumstances. Change frequencies only when there is a valid reason. However, request the position of an aircraft that is not visually sighted or displayed on radar if the location is not given by the pilot.Īlthough 121.5 MHz and 243.0 MHz are emergency frequencies, it might be best to keep the aircraft on the initial contact frequency. Normally, do not request this information from military fighter-type aircraft that are at low altitudes (for example, on approach, immediately after departure, on a low level route). If an emergency has been declared by an Emergency Autoland system, transmissions to the aircraft may go unanswered. Use the information provided to develop an appropriate course of action to assist the aircraft.
