Flight Mission Details

By Peter Hobbs

Goals of Flight:

- Climb to 10,000 ft and transit to COVE lighthouse
- Underfly Terra at COVE lighthouse at 100 ft (Terra overpass at 1542 UTC)
- BRDF near COVE lighthouse at 36 degrees 57.3 minutes North and 75 degrees 37.5 minutes West
- BRDF over Dismal Swamp
- Calibrate pressure, temperature, and winds against Wallops special sonde

Accomplishments of Flight:

- Done
- Done (CV-580 at lighthouse at Terra overpass time)
- Done at location slightly offset from prescribed point to avoid cloud
- Cancelled due to clouds over Dismal Swamp
- Done

Weather Conditions:

- Clear at take-off except for small cumulus clouds on the horizon. Increasing cumulus clouds during flight, with about 50% cumulus cloud cover over Wallops at end of flight. Low aerosol optical thickness (AOT), about 0.1 from surface.

Instrument Problems:

- Some problems with TANS locking on to satellite (affects pitch and roll angle measurements)

Additional Comments:

- Other aircraft flying: Cessna, Proteus, OV-10

Flight Path, Timing, and Measurements

1433: Engines on

1440: Take off

1440-1504: Climb to 10,000 ft on transit to COVE lighthouse

1504-1530: Descend at 500 ft/min then 1,000 ft/min to 100 ft

1530-1554: Runs at 100 ft over lighthouse. Over lighthouse at Terra overpass time of 1542 UTC.

1554-1559: Look for cloud-free spot near designated point for BRDF measurements

1559-1617: Seven CAR turns at 600 ft near designated spot

1617-1623: Climb to 4,000 ft to talk to CLAMS control. Advised that it was cloudy over Dismal Swamp but to proceed there to inspect visually.

1623-1632: Transited part way to Dismal Swamp. In view of considerable cloud in direction of Dismal Swamp, decided to cancel BRDF over swamp

1632-1715: Transit back to Wallops

1715-1735: Followed special radiosonde launched from Wallops to 12,000 ft for temperature, humidity, and wind comparisons.

1745: Touchdown at Wallops

1749: Engines off
