2/17/057110.65P CHG 210−2−16. EMERGENCY OBSTRUCTION VIDEOMAP (EOVM)a. The EOVM is intended to facilitate advisoryservice to an aircraft in an emergency situationwherein an appropriate terrain/obstacle clearanceminimum altitude cannot be maintained. It shall onlybe used and the service provided under the followingconditions:1. The pilot has declared an emergency, or2. The controller has determined that anemergency condition exists or is imminent because ofthe pilot’s inability to maintain an appropriateterrain/obstacle clearance minimum altitude.NOTE−Appropriate terrain/obstacle clearance minimum altitudesmay be defined as Minimum IFR Altitude (MIA), MinimumEn Route Altitude (MEA), Minimum ObstructionClearance Altitude (MOCA), or Minimum VectoringAltitude (MVA).b. When providing emergency vectoring service,the controller shall advise the pilot that any headingsissued are emergency advisories intended only todirect the aircraft toward and over an area of lowerterrain/obstacle elevation.NOTE−Altitudes and obstructions depicted on the EOVM are theactual altitudes and locations of the obstacle/terrain andcontain no lateral or vertical buffers for obstructionclearance.REFERENCE−FAAO 7210.3, Emergency Obstruction Video Map (EOVM), Para 3−9−4.10−2−17. VOLCANIC ASHa. If a volcanic ash cloud is known or forecast tobe present:1. Relay all information available to pilots toensure that they are aware of the ash cloud’s positionand altitude(s).2. Suggest appropriate reroutes to avoid the areaof known or forecast ash clouds.NOTE−Volcanic ash clouds are not normally detected by airborneor air traffic radar systems.b. If advised by an aircraft that it has entered avolcanic ash cloud and indicates that a distresssituation exists:1. Consider the aircraft to be in an emergencysituation.2. Do not initiate any climb clearances toturbine−powered aircraft until the aircraft has exitedthe ash cloud.3. Do not attempt to provide escape vectorswithout pilot concurrence.NOTE−1. The recommended escape maneuver is to reverse courseand begin a descent (if terrain permits). However, it is thepilot’s responsibility to determine the safest escape routefrom the ash cloud.2. Controllers should be aware of the possibility ofcomplete loss of power to any turbine−powered aircraftthat encounters an ash cloud.REFERENCE−FAAO 7110.65, Altitude Change for Improved Reception, Para 10−2−4.AIM, Flight Operations in Volcanic Ash, Para 7−5−8.Emergency Assistance10−2−7
