OK Ami I have retested with details below.
Main findings excluding activation depth:
1. Confirm speed reduction proceedure of your last post is OK
2. Speed increase works as you describe also - needs reame update.
3. After this proceedure Depth changes are out of sequence.
DW 1.03 (No additions) SW at depth etc as before.
You asked for detailed proceedures followed:
Mk 48 launched at 800 ft and self activated at RTE
Depth changes:
Torp at Launch depth.
1st. Pre - goes to Search
2nd. Pre - No change.
3rd. Pre - goes to Ceil. at 55 knts (Non active)
1. Speed reduction:
1st. Enable - goes to 40 knts (Active)
Push Pre (Non Active) NB. 4th Pre -Could this affect later problem ?
OK so now we are at Ceil Non Act at 40 knots lets speed up.
2. Speed Increase:
1st Enable - still 40 (Active)
2nd. Enable - goes to 55 knts. (Active)
Push Pre - goes Non Active. (Cumulative of Pres now 5th)
At Ceil then 55 knts NON Active lets dive -
3.Depth Change:
Push Pre - dives to Search (Cumulative 6th)
Push Pre - climbs to Ceil ( C=7th)
Push Pre - dives to Launch. (C=8th)
Push Pre - climbs to Search. (C=9th)
Push Pre - climbs to Ceil.
Wonder with the Pres whether the cumulative /reset is interfering ?
