You are carrying out an approach, you are on glideslope to land, and you encounter a microburst on your flight path and to the right. What effects does the aircraft suffer?

  • A

    Speed increase, drift right, slightly above the glideslope.

  • B

    Speed decrease, drift left, below glideslope.

  • C

    Speed increase, drift left, slightly above the glideslope.

  • D

    Speed decrease, drift right, below glideslope.

Refer to figure.
An aircraft approaching a downburst will first encounter a strong headwind, which will lead to an increase in indicated airspeed.

When the microburst is to the right of the aircraft – it will push the aircraft to the left, causing the aircraft to drift to the left.
The above-mentioned strong headwind causes an increase in lift (rate of descent decreases). Therefore, considering that you were established on the glideslope, you will now be above it.
