Sikorsky Pump

The Analog Channel Number 29 start to have problems during the Sikorsky 2005 field project. The channel had a lot of noise that increase during the project. The January 9, 2005 flight had only a little noise. See plot of 25 Hz analog volts given below.

The problem was really evident on the January 24, 2005 flight. See plot of 25 Hz analog volts given below.

Problem seems to be related to a problem with the number 29 channel on the analog board.

Move the TDL Pump flow rate measurement from channel 29 to channel 30 after the January 24, 2005 flight. Channel 30 had the same problem as channel 29 so the TDL flow rate measurment was moved back to Channel 29 before the January 29, 2005 flights.

Believe the problem may be related to the A/D board so we may swap all voltage measurement to new A/D board.
