The non-improved Test-71M has the following features.
While on the wire the ceiling, searchdepth, and floor are the three depths that can be selected using the preenable button. If the torpedo is left alone, it will run at its launchdepth until it reaches its preset runtoenable distance, at which point it will enable and conduct the search it was programmed to do.
The snake and circle buttons select for the snake and circle search patterns on this weapon. This weapon has no reattack function. The ASuW Safety is enabled by default as it is a ASW weapon, however, you can disable this feature by setting the ceiling at less than 16-18m ( i haven't decided yet). A single click of the enable button passive enables the torpedo and sets its speed at the max speed of its passive sensor using the designated search pattern. A second enable click active enables the torpedo using the designated search pattern.
The following regarding the TEST family search patterns is relevant to all TEST versions, and the NK version when NOT running in wakehoming mode. (Yes I know the presets are in meters, so I'll redo it in meters when I'm actually doing it). Since the TEST has a fairly limited vertical dimension on its sensors, it employs a helix pattern, oscillating between two preset depths in both circle and snake mode. The floor sets the bottom of the helix and the ceiling sets the top of the helix. If the floor and ceiling are set closer than 200ft, then the torpedo will go to its preset search depth (for a narrow depth band shot or for use in shallow water... it is always your reponsibility to make sure the torpedo doesn't hit the bottom). If the torpedo is not manually enabled, and the floor and ceiling are more than 200ft apart, the search depth will not be used (except for a preenable depth selection) and the torpedo will helix between the floor and ceiling preset depths.
If you choose to enable the torpedo manually, here is the choice you have for depth selection. If the torpedo is set to be at search depth, the torpedo will oscillate between the floor and the ceiling. If the torpedo is set to be at the floor, the torpedo will oscillate between the floor and the searchdepth, and if the torpedo is set to be at the ceiling when you manually enable it, the torpedo will oscillate between the ceiling and the search depth. You can reset the depth search by preenabling the torpedo and programming it to go to the proper depth to begin the search you want... you won't have to wait for the torpedo to actually go to that depth before enabling the search.
That's all I think for the TEST family... now for the rest!
