Minimum Vectoring Altitude MVA is the lowest altitude, expressed in feet AMSL Above Mean Sea Level, to which a radar controller may issue aircraft altitude clearances during vectoringdirect routing except if otherwise authorized for radar approaches, departures and missed approaches. MVA may also be referred to as Minimum Flight Altitude MFA, Minimum Radar Vectoring Altitude MRVA or ATC Surveillance Minimum Altitude ASMA. For the purpose of this article, the MVA term will be used. VectoringProvision of navigational guidance to aircraft in the form of specific headings, based on the use of an air traffic services surveillance system. ICAO Doc 4. PANS ATM. MVA Design. MVAs are established for use by the Air Traffic Controller ATCO when Air Traffic Control ATC provide a surveillance service usually radar. Each MVA chart see Figure 1 below contains sectors large enough to accommodate the vectoring of aircraft within the sector at the MVA. Each sector boundary is at least 3 miles from the obstruction used to determine the MVA in that sector. In order to avoid cases of large sectors with an excessively high MVA because of isolated prominent obstacles, the obstacle may be enclosed in a buffer area which boundaries are at least 3 miles from the obstacle. The minimum vectoring altitude in each sector provides 1. The MVA is the lowest altitude that meets obstacle clearance requirements in the airspace specified. According to ICAO PANS OPS minimum vectoring altitudes shall be corrected for temperature. The temperature correction shall be based on seasonal or annual minimum temperature records. GENERAL Instrument Departure and Approach Procedures Who is establishing the aerodrome operational minima for instrument approaches The appropriate authority of the. International Civil Aviation Organization Approved by the Secretary General and published under his authority Airborne Collision Avoidance System. AMENDMENTS The issue of amendments is announced regularly in the ICAO Journal and in the monthly Supplement to the Catalogue of ICAO Publications and Audiovisual.

Note 2, to provide the controller with minimum altitudes corrected for temperature effect. Whenever possible, minimum vectoring altitudes should be sufficiently high to minimize activation of aircraft ground proximity warning systems. Activation of the GPWS TAWS will induce the pilot to pull up immediately and climb steeply to avoid hazardous terrain, possibly compromising separation with other aircraft in close vicinity. MVA Publication. MVA charts shall be approved by the appropriate authorities in most cases this is the Civil Aviation Administration CAA and published in the Aeronautical Information Publication AIP as a section of the Aerodrome part AD related to the given aerodrome. According to ICAO Annex 4, Chapter 2. Power Tools Mod 1.8 on this page. ATC Surveillance Minimum Altitude Charts ICAO shall provide information that will enable flight crews to monitor and cross check altitudes assigned by a controller using an ATS surveillance system. Such MVA charts should be made available where vectoring procedures are established and minimum vectoring altitudes cannot be shown adequately due to excessive chart clutter on the.

Chapter 4, 4. 1. 3, the ATC Surveillance Minimum Altitude Charts ICAO shall, when available for designated international aerodromesheliports, form part of the AIP, or be distributed separately to recipients of the AIP. Also, Appendix 1 of Annex 1. Contents of Aeronautical Information Publication, indicates that States shall publish in the AIP The criteria used to determine minimum flight altitudes. MVA charts may vary in presentation from country to country and their titles may also vary. A CTRben vgrehajtsra kerl klnleges VFR replsekre vonatkozan elrst lsd az L Fggelk 1. Icao Pans Ops Doc 8168 Volume 1' title='Icao Pans Ops Doc 8168 Volume 1' />For example in Belgium the term ATC surveillance minimum is used. MVA Visualization. In order to provide the ATCO with the minimum vectoring altitudes, the MVA chart data may be uploaded on the radar data display system ODS. I is then presented to the ATCO as a part of the radar maps information. Responsibilities. Pilots responsibility. The pilot in command is responsible for the safety of the operation of the aircraft and the safety of the aeroplane and all persons on board during flight. This includes responsibility for obstacle clearance, except when an IFR flight is being vectored or given direct routing asssited by radar. When ATC is not providing a surveillance service radar and a pilot accepts a direct route which is off of the published route, then the pilot is wholly responsible for maintaining obstacle clearance.

PAN OPS, the pilot in command shall closely monitor the aircrafts position with reference to pilot interpreted navigation aids in order to minimize the amount of radar navigation assistance required and to mitigate the consequences resulting from a radar failure. The pilot in command shall also continuously monitor the communication with the ATCO while being radar vectored and shall immediately climb the aircraft to the minimum sector altitude if the ATCO does not issue further instructions within a suitable interval, or in case of a communication failure. The determination of the lowest usable flight levels by the air traffic control units within controlled airspace does not relieve the pilot in command of the responsibility to ensure that adequate terrain clearance exists, except when an IFR flight is being vectored or given direct routing assisted by radar. Many aircraft operators set company limits for descent clearance based on the Minimum Sector Altitude MSA and there have been reported cases when pilots have declined to descend to ATC assigned MVAs that are lower than the MSAs. The refusal to accept an ATC descent clearance to MVA can adversely affect the flow of traffic and become a safety issue, especially in busy airspace scenarios. Nevertheless, if the flight crew believe that a cleared altitude will put the aircraft at risk of collision with the terrain, they must ask for clarification of the ATC instruction expressing their concern. ATCOs responsibility. The objectives of the air traffic control service as prescribed in ICAO Annex 1. The procedures prescribed in Doc 4. PANS ATM do not relieve pilots of their responsibility to ensure that any clearances issued by air traffic control units are safe in this respect. When vectoring an IFR flight and when giving an IFR flight a direct routing which takes the aircraft off an ATS route, the controller shall issue clearances such that the prescribed obstacle clearance will exist at all times until the aircraft reaches the point where the pilot will resume own navigation. According to Doc 8. PAN OPS when an IFR flight is being vectored by radar, air traffic control ATC may assign minimum vectoring altitudes which are below the minimum sector altitude. Minimum vectoring altitudes provide obstacle clearance at all times until the aircraft reaches the point where the pilot will resume own navigation. The use of phrases as per PANS ATM, such as. ATC and hence a better appreciation of obstacle clearance responsibilities. Related Aticles. Further Reading. ICAOICAO Annex 6 Operation of Aircraft. ICAO Annex 1. 1 Air Traffic Services.
