Section 4. Services

  1. ADVANCE APPROACH INFORMATION

Assign responsibility for issuing advance approach information to a specific position when more than one position could issue the data. Responsibility must be delegated in a directive in accordance with FAA Order 1320.1, FAA Directives System. Display the information so that it is accessible to the controllers having need for it.

  1. MINIMUM IFR ALTITUDES (MIA)

Determine minimum IFR altitude information for each control sector and display them at the sector. This must include off‐airway minimum IFR altitude information to assist controllers in applying 14 CFR section 91.177 for off‐airway vectors and direct route operations. Facility air traffic managers must determine the appropriate chart/map method for displaying this information at the sector. Facilities must submit their MIA charts for review periodically. Submit MIA charts to Aeronautical Information Services (AIS), including automated data submissions, to ensure that obstacle clearance and controlled airspace requirements are met.

NOTE-

  1. This may be accomplished by appending the data on sector charts or MVA charts. Special translucent sectional charts are also available. For assistance in obtaining MIA sector charts contact the Radar Video Map group at 9-AJV-HQ-ATCPRODUCTS@faa.gov.
  2. For guidance in the preparation and review of Minimum IFR Altitude charts see FAA Order JO 7210.37, En Route Instrument Flight Rules (IFR) Minimum IFR Altitude (MIA) Sector Charts.

FAA Order JO 7210.3, Para 3-8-2, Radar Mapping Standards.

  1. SPECIAL USE FREQUENCIES

Special use frequencies (296.7, 321.3, 364.8 and 369.9MHz) are controller‐to‐pilot communication channels established to minimize frequency changes for certain military aircraft operating in the high altitude sectors. The specific frequencies must not be publicized. However, information concerning their authorized use may be published in official military documents or in agency directives.

  1. PRACTICE INSTRUMENT APPROACHES
  1. Where ARTCCs provide approach control service, ATMs must evaluate those airports where basic radar service is available for determining where IFR separation to VFR aircraft conducting practice instrument approaches will be provided. The ATM must consider the impact on operations and service requirements when determining the airports that will receive this additional service.
  2. ATMs must issue a Letter to Airmen (LTA) advising the users of airports where IFR separation is provided for VFR aircraft conducting practice instrument approaches. The LTA must specify which facility will handle the aircraft practicing instrument approaches and include the appropriate frequencies. Airport(s) where this service is provided must be specified in a facility directive.

FAA Order JO 7210.3, Para 4-5-2, Letters to Airmen.

  1. Where a facility directive requires the application of IFR separation to VFR aircraft practicing instrument approaches, IFR separation must be provided in accordance with FAA Order JO 7110.65, Chapter 4, Section 8.
  2. Temporary conditions (e.g., available staffing, equipment operating status, VIP movement, TFRs, or unusual operations) may impact a facility's ability to provide practice instrument approach services. Facilities may elect to suspend practice instrument approaches when a temporary condition exists.
  3. At airports with a nonapproach control tower, or an airport with a Flight Service Station (FSS) that provides Local Airport Advisory (LAA), procedures for handling VFR aircraft conducting practice instrument approaches must be included in an LOA, if applicable.
