FORTRAN routine C_PRESS1
:ROUTINE:
C_PRESS1 SUBROUTINE FORTVAX
:PURPOSE:
Calibrates the cabin pressure sensor and the S9 static port.
:DESCRIPTION:
Apply calibration the combined transducer and DRS
coefficients to DRS parameters 14 and 221 to obtain derived
parameters 579 and 778. Invalid data is flagged with 3, data
outside limits is flagged with 2.
:METHOD:
For each DRS parameter to be calibrated
1. If data is FFFF or FFFE then flag 3
2. Apply the calibration constants
3. Check the results for being within acceptable values.
4. Set data flag bits (16+17)
:FLAGGING:
| 0 = Good data
| 1 = Data of lower quality
| 2 = Probably faulty, exceed lims
| 3 = Data absent or invalid.
Flagging - If a value can't be computed, due to missing data
missing constants, divide be zeroes, etc, a value of 0 is
used, flagged with a three. If a value is outside its
limits for range or rate of change, it is flagged with a two.
If there are no problems with the data it is flagged with 0.
