Wind on the ILS

Youre descending on the glideslope for the ILS 29 with a 25-knot tailwind. Winds at the surface are eight knots from the southwest. Quick: What two corrective actions will you need to make over the next three minutes? With enough experience youll get it right, but ask yourself: Is this brand of analysis second nature to you? Sure, you can just follow the needles and correct, but thats accepting being behind the curve rather than mastering it. An understanding of the variables affecting an approach path give you the capacity for proactive, rather than reactive, piloting.

Key Takeaways:

• Pilots should adopt a proactive approach to ILS/LPV guidance, envisioning the approach path and anticipating changes rather than simply reacting to needle deflections.
• Mastering lateral guidance involves continuously updating a "reference heading" to compensate for wind, using tools like GPS Track (TRK) to maintain precise centerline.
• Mastering vertical guidance centers on managing the descent rate by monitoring groundspeed and establishing a "reference pitch" to stay on the glideslope.
• Successful approaches require continuous monitoring of track and groundspeed, leading to small, measured, and anticipatory adjustments in both heading and pitch to prevent significant deviations.
