8. ILS or LPV Instrument Approach

Aim

To determine the candidate’s ability to safely fly a successful ILS or LPV approach.

Description

After transitioning to the approach facility or after receiving vectors from ATC or the examiner, the candidate will intercept the localizer and glide slope and descend to the decision height (DH) or decision altitude (DA) as specified on the approach chart. 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 ILS or LPV instrument approach procedure to be performed;

  4. select, tune, identify and confirm the operational status of ground and helicopter navigation equipment to be used for the approach procedure;

  5. establish the appropriate configuration (power setting and airspeed) and vary appropriately  considering turbulence, wind shear, microburst conditions, or other meteorological and operating conditions;

  6. complete the helicopter check list items appropriate to the phase of flight or approach segment, including engine-out emergency checklist, as applicable;

  7. apply necessary adjustment to the published DH or DA and visibility criteria, as required, because of NOTAMS, inoperative helicopter and/or ground navigation equipment 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. on final approach course, allow no more than ½ scale deflection of the localizer or glideslope indications;

  10. during an LPV approach on the final course, ensure transition to approach active mode within 2 nm prior the Final Approach Waypoint (FAWP);

  11. during an LPV approach, take appropriate action in the event that a RAIM alert is displayed when the aircraft is established on the final approach course;

  12. maintain declared approach airspeeds within ±10 knots; and

  13. maintain a stabilized descent to the DH/DA to permit completion of the visual portion of the approach; or

  14. initiate the missed approach procedure, upon reaching the DH/DA, when the required visual references for the intended runway or heliport are not obtained.

Note 1: LPV means Localizer Performance with Vertical Guidance for RNAV(GNSS) approaches with LPV minima.  The aircraft must be equipped with WAAS Class 2 or 3 avionics meeting TSO C145a/C146a.  Refer: AIM - COM 3.16.5.2.3.

Note 2: LPV approaches will be indicated on the flight test report by filling the ILS circle and inserting a note in the Remarks section of the report.
