Missed Approach

Question 1

WHEN MUST YOU CONDUCT A MISSED APPROACH ?

Answer 1

1 When the aircraft is not within the
navigation tolerances during the
FINAL SEGMENT of an instrument
approach

2 You do not have the required
VISUAL REFERANCE at or before
the missed approach point

3 You loose VISUAL REFERANCE
whilst in the circling area

4 The radio aid fails or becomes
suspect whilst below MSA

5 A straight in landing cannot be done
from an instrument approach UNLESS
CONDITIONS ARE EQUAL TO OR
BETTER FOR A CIRCLING APPROACH

  RNAV (GNSS)

1     If a loss of RAIM or RAIM warning
      is indicated at any time after 
      passing the IAF, the pilot must
      immediately carry out a missed
      approach.

2    Provided the RAIM warning ceases
      when the missed approach is 
      selected on the GPS receiver, the
      GPS may be used for missed
      approach guidance.

3    Should the RAIM warning remain
      when the missed approach is 
      selected, or should there be any 
      doubt about the accuracy of the 
      GPS, then an alternative means
      of guidance or dead reckoning
      must be used to fly the missed 
      approach.
