5.5.5. Missed Approach a. Pilot. 1. Executes a missed approach when one of the following conditions exist: (a)Arrival at the Missed Approach Point (MAP) or the Decision Height (DH) and visual reference to the runway environment is insufficient to complete the landing. (b)Determines that a safe approach or landing is not possible (see subparagraph 5.4.21h). 5.5.2 Pilot/Controller Roles and Responsibilities (c) Instructed to do so by ATC. 2.Advises ATC that a missed approach will be made. Include the reason for the missed approach unless the missed approach is initiated by ATC. 3.Complies with the missed approach instruc-tions for the IAP being executed from the MAP, unless other missed approach instructions are specified by ATC. 4.If executing a missed approach prior to reaching the MAP, fly the lateral navigation path of the instrument procedure to the MAP. Climb to the altitude specified in the missed approach procedure, except when a maximum altitude is specified between the final approach fix (FAF) and the MAP. In that case, comply with the maximum altitude restriction. Note, this may require a continued descent on the final approach. 5.Following a missed approach, requests clearance for specific action; i.e., another approach, hold for improved conditions, proceed to an alternate airport, etc. b. Controller. 1.Issues an approved alternate missed approach procedure if it is desired that the pilot execute a procedure other than as depicted on the instrument approach chart. 2.May vector a radar identified aircraft executing a missed approach when operationally advantageous to the pilot or the controller. 3.In response to the pilot’s stated intentions, issues a clearance to an alternate airport, to a holding fix, or for reentry into the approach sequence, as traffic conditions permit. 5.5.6. Radar Vectors a. Pilot. 1.Promptly complies with headings and altitudes assigned to you by the controller. 2.Questions any assigned heading or altitude believed to be incorrect. 3.If operating VFR and compliance with any radar vector or altitude would cause a violation of any CFR, advises ATC and obtains a revised clearance or instructions. AIM b. Controller. 1. Vectors aircraft in Class A, Class B, Class C, Class D, and Class E airspace: (a)For separation. (b)For noise abatement. (c)To obtain an operational advantage for the pilot or controller. 2.Vectors aircraft in Class A, Class B, Class C, Class D, Class E, and Class G airspace when requested by the pilot. 3.Vectors IFR aircraft at or above minimum vectoring altitudes. 4.May vector VFR aircraft, not at an ATC assigned altitude, at any altitude. In these cases, terrain separation is the pilot’s responsibility. 5.5.7. Safety Alert a. Pilot. 1.Initiates appropriate action if a safety alert is received from ATC. 2.Be aware that this service is not always available and that many factors affect the ability of the controller to be aware of a situation in which unsafe proximity to terrain, obstructions, or another aircraft may be developing. b. Controller. 1. Issues a safety alert if aware an aircraft under their control is at an altitude which, in the controller’s judgment, places the aircraft in unsafe proximity to terrain, obstructions or another aircraft. Types of safety alerts are: (a)Terrain or Obstruction Alert. Immedi-ately issued to an aircraft under their control if aware the aircraft is at an altitude believed to place the aircraft in unsafe proximity to terrain or obstructions. (b)Aircraft Conflict Alert. Immediately issued to an aircraft under their control if aware of an aircraft not under their control at an altitude believed to place the aircraft in unsafe proximity to each other. With the alert, they offer the pilot an alternative, if feasible. 2. Discontinue further alerts if informed by the pilot action is being taken to correct the situation or that the other aircraft is in sight. Pilot/Controller Roles and Responsibilities 5.5.3 5.5.8. See and Avoid a. Pilot. When meteorological conditions permit, regardless of type of flight plan or whether or not under control of a radar facility, the pilot is responsible to see and avoid other traffic, terrain, or obstacles. b. Controller. 1.Provides radar traffic information to radar identified aircraft operating outside positive control airspace on a workload permitting basis. 2.Issues safety alerts to aircraft under their control if aware the aircraft is at an altitude believed to place the aircraft in unsafe proximity to terrain, obstructions, or other aircraft. 5.5.9. Speed Adjustments a. Pilot. 1.Advises ATC any time cruising airspeed varies plus or minus 5 percent or 10 knots, whichever is greater, from that given in the flight plan. 2.Complies with speed adjustments from ATC unless: (a) The minimum or maximum safe airspeed for any particular operation is greater or less than the requested airspeed. In such cases, advises ATC. NOTE. It is the pilot’s responsibility and prerogative to refuse speed adjustments considered excessive or contrary to the aircraft’s operating specifications. (b) Operating at or above 10,000 feet MSL on an ATC assigned SPEED ADJUSTMENT of more than 250 knots IAS and subsequent clearance is received for descent below 10,000 feet MSL. In such cases, pilots are expected to comply with 14 CFR Section 91.117(a). 3. When complying with speed adjustment assignments, maintains an indicated airspeed within plus or minus 10 knots or 0.02 Mach number of the specified speed. |
