The Mission takes place in Shallow Water, .. thus your 'Deep' buoys will be useless. They operate at 400 feet, .. and in the Demo Mission they will end up in the Mud. So, .. at the Loadout screen, .. chuck out all the Deep Buoys, .. and stock up on the Shallow Ones. At the same time, .. throw out all the BT Buoys, .. for the same reason above ... you won't be needing them.
The default 'Dipping' height is 50 feet ... shortcut key=Shift+2. If you use the default height, .. you only need to stream the hydrophone out to 150 feet. That'll give you 100 feet in the water, .. which is sufficient for operating in Shallow waters. If you prefer to hover higher (there will be instances when you will WANT to do that, .. but not in the demo) .... then adjust the hydrophone cable length accordingly.
Be very careful about hovering low e.g. 50 feet, ... and then moving off at high speed. The Helo will drop in altitude as it moves forward, ... and the greater the increase in speed, ... the greater the tilt of the rotor, .. which will cause the Helo to lose altitude abruptly .... and you'll probably end up ... swimming with da fishes.
1st Update: DICASS buoys need 3 Grams to use them in ACTIVE Mode (pinging). If all your Grams are currently tuned to other buoys, ... in addition to the DICASS buoy, ... then use the GRAM CONTROL selection buttons and the FREQUENCY SELECT wheels ... to re-tune those Grams to Channel 00. This will clear any data from the Gram. As soon as you have 2 non-assigned Grams, .. then click the MODE switch on the DICASS buoy, ... the first click will put the DICASS into Directional Mode (uses 2 Grams), .. and a subsequent click of the MODE switch, .. will put the DICASS into Active Mode (using 3 Grams). Although the DICASS is now in Active Mode, ... you still need to start pinging, .. by pressing the XMIT button on the lower left of the controlling Gram. The XMIT will ONLY appear, .. once the DICASS buoy has been put into Active Mode.
Using MAD. Firstly, .. although the MAD sensor is streamed, ... it is not automatically ON. You need to turn the MAD on from the MAD/ESM station. The autocrew does not need to be on for them to report MAD/SAD detections. The only time you will need to turn the Autocrew on, at the MAD/ESM station, .. is for ESM detections.
Although every situation could be different, ... a good MAD/SAD search altitude would be ~250 to 300 Feet. Speed is not critical, ... but, keep it below ~80 knots.
Merging Contacts. You cannot 'Merge' contacts on the Helo. Lines of intersection, from your buoy detections, .. are the way to triangulate a solution. You will need to 'manually' update i.e. MARK ... the contacts from time to time ... in order that the Nav Map can display a new intersection point.
