Elements and Performance Criteria
- Select approach and determine applicable minima
- IAL is reviewed and briefed to flight crew in relation to directing entry to the approach, lowest safe altitude (LSALT) or minimum safe altitude (MSA) is maintained prior to entry and tracks, distances, timing and descent limitations are maintained for the approach
- Fuel availability and latest divert time procedures are enacted as required
- Monitor aid signal integrity
- Morse code identification and NDB indications are monitored throughout selected approach to ensure signal integrity
- Conduct initial approach
- Aircraft is manoeuvred to holding fix on an inbound track and at or above route MSA or LSALT is maintained in accordance with aeronautical information publication (AIP) requirements, using the NDB
- Conduct holding pattern
- Holding pattern is performed in accordance with AIP, using the NDB
- Conduct instrument approach procedure
- Instrument approach is conducted in accordance with tolerances specified in AIP using the NDB
- Landing runway is identified
- After establishing visual reference, a visual circling or runway approach is conducted for a landing on selected runway in accordance with AIP
- Conduct missed approach procedure
- Aircraft is manoeuvred to missed approach point (MAPt)
- Missed approach procedure is conducted in accordance with the IAL chart
- Obstacle clearance in instrument meteorological conditions (IMC) is maintained
