8. RNAV(GNSS) Instrument Approach

Aim

To determine the candidate’s ability to safely fly a successful RNAV (GNSS) approach.

Description

The candidate will fly the approach tracks depicted on the approach chart and fly the approach to the MAWP or to a landing. The candidate will control the helicopter solely with reference to flight instruments.

Performance Criteria

Assessment will be based on the candidate’s ability to:

  1. establish two-way communications with ATC using the proper communications phraseology and techniques, as required for the phase of flight or approach segment;
  2. comply in a timely manner, with all clearances, instructions, and procedures issued by ATC and advise accordingly if unable to comply;
  3. select and comply with the RNAV instrument approach procedure to be performed;
  4. retrieve the RNAV approach from the database and verify the approach waypoints used for the approach procedure;
  5. establish the appropriate configuration and airspeed considering turbulence, wind shear, microburst conditions or other meteorological and operating conditions;
  6. complete the check list items appropriate to the phase of flight or approach segment, including engine-out approach and landing checklist, when applicable;
  7. apply necessary adjustment to the published Minimum Descent Altitude (MDA) and visibility criteria, as required, because of NOTAMS, inoperative helicopter equipment and/or inoperative visual aids associated with the landing environment;
  8. prior to final approach course, maintain altitudes, as cleared or as declared, (±100 feet) and maintain headings (±10 degrees);
  9. take appropriate action in the event that a RAIM alert is displayed when the helicopter is established on the final approach course;
  10. on the intermediate and final segments of the final approach course:
    1. maintain GPS track bar within ½ scale deflection;
    2. fly the approach in a relatively stable manner without descending below the applicable minimum altitudes depicted on the approach chart (+as required/ –0 feet);
    3. confirm the approach mode is active within 2 nm prior to reaching the Final Approach Waypoint (FAWP) inbound; and
    4. descend to and accurately maintain the Minimum Descent Altitude (MDA) and track to the Missed Approach Waypoint (MAWP) or to the recommended minimum visibility that would permit safe completion of the visual portion of the approach with a normal rate of descent and non excessive manoeuvring.
  11. maintain the declared approach airspeeds within ±10 knots; and
  12. maintain a stabilized descent to the MAWP to permit completion of the visual portion of the approach; or
  13. maintain a stabilized descent to the MAWP and initiate the missed approach procedure when the required visual references for the intended runway or heliport are not obtained
