ENSURE SAFETY PRECAUTIONS ARE OBSERVED WHILE
ACTIVATING SONDE BATTERY AND HANDLING SENSOR PROBE.
SENSOR PROBE IS EASILY BROKEN IF BENT TO SHARPLY. IF
PROBE IS BROKEN, THE SONDE IS RENDERED USELESS.
c. Activate sonde (para 2.1).
d. Check for activated sonde signal (para 1.2.3 and 1.5).
e. Retune sonde if necessary (para 2.2).
f. Select wind measuring method.
(1) OMEGA/VLF (para 1.2.4. step a.).
(2) LORAN-C (para 1.2.4. step b.)
g. Input current station location (para 1.2.6).
NOTE
Enter station altitude in meters.
h. Enter calibration coefficients (para 1.3).
i. Enter surface observations (para 1.7).
NOTES
Current PTU data information can be obtained from activated sonde
(para 1.6).
Wind speed is entered in meters par second (m/s). Refer to Table 2-7
for conversion of knots to m/s.
j. Launch balloon (para 1.6).
NOTE
Insure "RELEASE" prompt is displayed before launching balloon.
k. Check reception of NAVAID network signals (para 1.8).
I. Monitor flight data (para 4).
NOTE
Paragraph 4.4.1 describes the OMEGA/VLF mode. For LORAN-C mode,
use paragraph 4.4.1 descriptions and Figure 2-7 for display illustration.
m. Terminate data collection from the sonde (para 1.10).
