5 − 5 − 3. Contact Approach a. Pilot. b. Controller. 5 − 5 − 4. Instrument Approach a. Pilot. b. Controller. REFERENCE − 1. Must request a contact approach and makes it in lieu of a standard or special instrument approach. 2. By requesting the contact approach, indicates that the flight is operating clear of clouds, has at least one mile flight visibility, and reasonably expects to continue to the destination airport in those conditions. 3. Assumes responsibility for obstruction clear- ance while conducting a contact approach. 4. Advises ATC immediately if unable to continue the contact approach or if encounters less than 1 mile flight visibility. 5. Is aware that if radar service is being received, it may be automatically terminated when told to contact the tower. Pilot/Controller Glossary Term −  Radar Service Terminated. REFERENCE − 1. Issues clearance for a contact approach only when requested by the pilot. Does not solicit the use of this procedure. 2. Before issuing the clearance, ascertains that reported ground visibility at destination airport is at least 1 mile. 3. Provides approved separation between the aircraft cleared for a contact approach and other IFR or special VFR aircraft. When using vertical separation, does not assign a fixed altitude, but clears the aircraft at or below an altitude which is at least 1,000 feet below any IFR traffic but not below Minimum Safe Altitudes prescribed in 14 CFR Section 91.119. 4. Issues alternative instructions if, in their judgment, weather conditions may make completion of the approach impracticable. 1. Be aware that the controller issues clearance for approach based only on known traffic. 2. Follows the procedure as shown on the IAP, including all restrictive notations, such as: 1. Issues an approach clearance based on known traffic. 2. Issues an IFR approach clearance only after the aircraft is established on a segment of published AIM, Chapter 7, Section 3, Cold Temperature Barometric Altimeter Errors, Setting Procedures, and Cold Temperature Airports (CTA) AIM, TBL 7 − 3 − 1, ICAO Cold Temperature Error Table REFERENCE − 8/15/19 3/15/07 7/16/20 AIM  7110.65R CHG 2 AIM AIM, Paragraph 5 − 4 − 20 , Approach and Landing Minimums 3. Upon receipt of an approach clearance while on an unpublished route or being radar vectored: 4. When applicable, apply cold temperature correction to instrument approach segments. Advise ATC when intending to apply cold temperature correction and of the amount of correction required for each affected segment on initial contact (or as soon as possible). This information is required for ATC to provide aircraft appropriate vertical separa- tion between known traffic. (a) Complies with the minimum altitude for IFR; and (b) Maintains the last assigned altitude until established on a segment of a published route or IAP, at which time published altitudes apply. (g) The circling minimums published on the instrument approach chart provide adequate obstruc- tion clearance and pilots should not descend below the circling altitude until the aircraft is in a position to make final descent for landing. Sound judgment and knowledge of the pilot’s and the aircraft’s capabilities are the criteria for determining the exact maneuver in each instance since airport design and the aircraft position, altitude and airspeed must all be considered. (a) Procedure not authorized at night; (b) Approach not authorized when local area altimeter not available; (c) Procedure not authorized when control tower not in operation; (d) Procedure not authorized when glide slope not used; (e) Straight-in minimums not authorized at night; etc. (f) Radar required; or Pilot/Controller Roles and Responsibilities 5 − 5 − 2
