Flight plan#

Arrive @FL200 at 16:09 UTC at WP1 - holding pattern until 16:29 UTC.

At 16:29 UTC: WP1 -> WP2 at cloud top (max FL280, ~20min). HALO passes over us at 16:39 UTC at FL450 at HALO_meet (13.0 N, -24.04 W). Holding pattern at WP2 for 5 min to allow for westward scan direction of SEA-POL radar on RV Meteor.

16:55 UTC: WP2 -> WP3 -> WP2 -> …: Descent with 1000 ft/min from cloud top down to FL010.

Arrive at WP4 (RV Meteor) at FL010 (safe altitude from SEA-POL radar).

Spiral ascent from FL010 to cloud top (max. FL280). Ascent as race-track pattern with one straight leg between WP5 and WP6: - WP5: -23.4785 W, 13.0 N - WP6: -23.5215 W, 13.0 N

Return home to RAI: descent through potential clouds on the way home.
