Questions and Answers

What is the primary objective of a precision ILS approach?

  • To guide the aircraft horizontally along the runway’s extended centerline
  • To transition the aircraft from the en route airspace structure to the landing (correct)
  • To conduct the approach briefing
  • To navigate the aircraft using only the glide slope
  • At what point should the pilot set flaps to 10 degrees and slow to approach speed during a precision ILS approach?

  • Upon reaching the Decision Altitude
  • Prior to intercepting the final approach course (correct)
  • During the descent from the en route altitude
  • When cleared for the approach
  • What is the purpose of the localizer and glide slope during a precision ILS approach?

  • To provide horizontal guidance only
  • To provide both horizontal and vertical guidance (correct)
  • To provide vertical guidance only
  • To provide navigation facilities only
  • What should the pilot do upon reaching the Decision Altitude (DA) during a precision ILS approach?

    Study Notes

    Precision ILS Approach

    • Provides horizontal and vertical guidance to aircraft in Instrument Meteorological Conditions (IMC) to land at an airport
    • Objective: transition aircraft from en route airspace structure to landing
    • Guides aircraft horizontally and vertically along runway's extended centerline

    Procedures for Precision ILS Approach

    • Study selected approach plate and conduct approach briefing
    • Tune and identify appropriate navigational facilities
    • Check and set heading indicator against magnetic compass
    • Complete before landing checklist
    • Set flaps to 10 degrees and slow to approach speed prior to intercepting final approach course
    • Track localizer inbound until intercepting glide slope
    • Track localizer and glide slope to Decision Altitude (DA)
    • Execute normal approach and landing procedure at DA with runway environment in sight
    • Execute missed approach procedure at DA with no visual contact with runway environment

    Missed Approach Procedure

    • Formulated for each published instrument approach
    • Allows pilot to return to airway structure while remaining clear of obstacles
    • Objective: safely and efficiently transition from final approach segment to missed approach segment when landing minimums not met
    • Initiated at point where aircraft has descended to authorized landing minimums at specified distance or time from facility with no visual contact
    • Initiated when directed by ATC

    Procedures for Missed Approach

    • Study approach plate to become familiar with published missed approach flight path or directions given by ATC
    • Apply full power and establish climb pitch attitude at DA or Missed Approach Point (MAP) with no visual contact
    • Retract flaps with positive rate of climb
    • Proceed as directed along missed approach path
    • Notify ATC of missed approach
