VARIABLE ASCENT RATE
Alerts associated with Ascent Rate are based upon 2 sets of speeds which change
at a reference depth of 60 FT (18 M).
WARNING: At depths greater than 60 FT (18 M), Ascent Rates
should not exceed 60 FPM (18 MPM). At depths of 60 FT (18
M) and shallower, Rates should not exceed 30 FPM (9 MPM).
Ascent Rate Warning
At depths deeper than 60 FT (18 M), a Warning (Fig. 67) will be given when
Ascent Rates exceed 50 FPM (15 MPM). The message SLOW > SLOW will scroll
until the Ascent is slowed. At 60 FT (18 M) and shallower, the Warning will be
given when Ascent Rates exceed 25 FPM (7.5 MPM).
Ascent Rate Alarm
At depths deeper than 60 FT (18 M), an Alarm will sound when Ascent Rates
exceed 60 FPM (20 MPM).
At 60 FT (18 M) and shallower, the Alarm will sound when
Ascent Rates exceed 30 FPM (10 MPM).
The Audible will sound, the red LED will flash, and the message
SLOW > SLOW will scroll on/off at the top of the screen. The
Audible and LED will stop when acknowledged with the S
button or when the Ascent is slowed. After acknowledged, the
message SLOW > SLOW will continue to scroll until the Ascent
is slowed below the Alarm rate.
