Deployment cook-20100321T1440
Pilot Notes
Waypoint Suggestion via email: Ok, sounds like a plan. I\'ll get the new waypoint in at the noon surfacing. I\'m still tuning. I\'ve got the heading about as good as can be fling in low power mode. I\'m now tuning the thermal engine. It seems that we\'re not getting a full thermal charge forcing the charge pump to come on at the surface. The software looks at this pressure and if it\'s not above the required(sensor: f_thermal_reqd_acc_pres(bar) 188) the pump comes to top it off before it will dive. So I\'ve been reducing the required thermal accumulator pressure down in small increments until the pump is not needed and the engine is able to supply the required accumulator pressure. This pressure effects our buoyancy drive, the lower the pressure the less oil we have to change the buoyancy. The good news is Cook has an accumulator capacity of 540cc, 140cc more than Drake. I\'ll be done tomorrow and resume 4 yo flights.

Good morning Tod: We have a new waypoint to suggest for Cook. We looked at the altimetry yesterday in class. and saw that our blue route from last week was not as favorable this week due to the interaction of the two counterclockwise eddies between 22 N and 23 N. Students from the class redefined a more favorable route and colored it green. John\'s shift of the google altimetry image reveals a continuous meandering current to the east along 26.5 N. We\'d like to try for the green route up to this meandering current outlined in red. The new waypoint to get us into the center of the next eddy is 23 00 N, 60 50 W. its about 200 km away. You can read details on the Thermal Glider Flight blog. http://www.i-cool.org/?cat=75 Thanks Scott
