  • Chapter 10: IFR Flight › Approach to an Airport With an Operating Tower, With an Approach Control › Approaches to Parallel Runways

    Approaches to Parallel Runways Procedures permit ILS instrument approach operations to dual or triple parallel runway configurations. A parallel approach is an ATC procedure that permits parallel ILS approach to airports with parallel runways separated by at least ... feet between centerlines. Wherever parallel approaches are in progress, pilots are informed that approaches to both runways are in use. Simultaneous approaches are permitted to runways: 1. With centerlines separated by 4,300 to 9,000 feet; 2. Equipped with…

  • Chapter 10: IFR Flight › Approaches › Approach to an Airport With an Operating Tower, With an Approach Control

    Radar vectors and altitude/flight levels are issued as required for spacing and separating aircraft; do not deviate from the headings issued by approach control. 4. Aircraft are normally informed when it becomes necessary to be vectored across the final approach ... course for spacing or other reasons. If approach course crossing is imminent and the pilot has not been informed that the aircraft will be vectored across the final approach course, the pilot should query the controller. The pilot…

    that are separated by 1,200 feet or less, followed by a straight-in landing on the adjacent runway. Aircraft executing a side-step maneuver are cleared for a specified nonprecision approach and landing on the adjacent parallel runway ... example, “Cleared ILS runway 7 left approach, side-step to runway 7 right.” The pilot is expected to commence the side-step maneuver as soon as possible after the runway or runway environment is in sight. Landing minimums…

  • Chapter 10: IFR Flight › Approach to an Airport With an Operating Tower, With an Approach Control › Radar Monitoring of Instrument Approaches

    Radar service is automatically terminated at the completion of a radar approach. No-Gyro Approach is available to a pilot under radar control who experiences circumstances wherein the directional gyro or other stabilized compass is inoperative or inaccurate. When this ... occurs, the pilot should so advise ATC and request a no-gyro vector or approach. The pilot of an aircraft not equipped with a directional gyro or other stabilized compass who desires radar handling may also request a no-gyro…

    instrument approach and advises “change to advisory frequency approved.” When the aircraft arrives on a “cruise” clearance, ATC does not issue further clearance for approach and landing. If an approach clearance is required, ATC authorizes the pilots to execute ... choice of standard instrument approach (if more than one is published for the airport) with the phrase “Cleared for the approach” and the communications frequency change required, if any. From this point on, there is no contact with…

  • Chapter 4: Approaches › Minimum Descent Altitude (MDA), Decision Altitude (DA), And Decision Height (DH)

    types of approaches. NDB and circling approaches are two common examples where the OpSpecs minimum listed altitudes may be more restrictive than the published minimums. Many Part 121 and 135 operators are restricted from conducting circling approaches below ... many have specific visibility criteria listed for NDB approaches that exceed visibilities published for the approach (commonly 2 SM). In these cases, flight crews must determine which is the more restrictive of the two and comply with those minimums…
