Mission:  ________________________________   Glider S/N:  _____________

Pilot / Engineer:  ______________________________   Date:  ________________

1. Pre-Recovery Coordination¶

• Field team arrival time, recovery time, and schedule-change likelihood discussed with the remote pilot
• Communication method and position-update frequency agreed
• Glider configuration confirmed  call-in interval, strobe

2. Remote Pilot — Set to Drift¶

• Glider caught on the surface; surfacing interval shortened
• XML script disabled in SFMC
• u_max_time_in_gliderdos set for the expected drift duration
• put c_de_oil_vol 420 — max buoyancy
• strobe on (unless broad daylight)
• Field team receiving regular GPS position updates

3. Field Team — Organize the Deck¶

• Grapple on 20 m line, boathook, glider cart staged
• Transport case opened, latches flattened
• Communication with remote pilot confirmed for glider position

4. Deploy Nose Recovery Line¶

• Remote pilot sends put c_recovery_on 1 when field team is ~10 min out or has visual contact
• Nose release confirmed  can take up to 10 min to unravel
• If not released after 10 min: retry command, boat-hook tap, or shallow dive test (see Remote Pilot procedure troubleshooting)

5. Recovery¶

• Vessel approached glider from downwind
• Line grappled/hooked and hauled in; overhand knot tied and attached to A-frame/crane
• Glider lifted nose-first out of the water
• Glider lowered onto cart, nose into ring-mount, strap secured
• Wings removed
• (If nose system failed) Backup workboat recovery used — see Field Recovery Procedure

6. Shutdown (Remote Pilot)¶

• Glider positioned with clear view of sky; pilot notified
• put c_air_pump 0 — air bladder deflated
• put c_de_oil_vol -420 — ballast pump retracted; get m_de_oil_vol confirms −420
• exit — glider shut down
• UTC shutdown time recorded and passed to field team

7. Stowing (Field Team)¶

• Within 30 minutes of shutdown: green plug removed, red plug installed
• Glider placed in transport case, cart legs seated correctly
• Both ratchet straps fastened, lid replaced
