Navigation (Cold Waters)

Here is some information about the **navigation**  in *Cold Waters*:

## NAVIGATION

Controlling the submarine involves the utilization of dynamic forces, primarily managed through the rudder and planes, resembling the operation of slow underwater aircraft. Additionally, there are trim control and a hover system for low-speed maneuvers.

In Cold Waters, the submarine can be directed conventionally by instructing the helmsman or dive officer to follow a specific course or depth. Alternatively, direct control can be assumed at any time, resembling the operation of an underwater flight simulation.

## SHIP DATA

The data panel above the mini-map comprises three columns: Ownship data, Contact Data, and Weapon data (torpedo on a wire). The first column presents information on the current course, speed, depth, rudder, planes, and ballast settings of the submarine. Adjusting these elements reflects their updated status.

## SPEED

Speed adjustments are made using Q and Z. The submarine's speed can be modified in various increments, ranging from Back Emergency to Ahead Flank. The graphical telegraph and ordered speed on the helm control panel offer alternative methods for controlling speed, allowing precise adjustments. Changes in speed have a time delay, impacting acceleration and deceleration.

## CAVITATION

Cavitation, resulting from a rapidly turning propeller, generates noise that can disclose the submarine's position. The impact of cavitation is influenced by depth, with higher depths mitigating the noise effect. Sonar notifications and a status icon indicate cavitation, affecting the submarine's stealth.

## FLOW NOISE

Increased speed amplifies the submarine's noise, termed flow noise, hindering sonar sensitivity. Flow noise complicates signature analysis and enhances enemy sonar detection. Strategic management of speed, cavitation, and noise is crucial for successful submarine command.

## EFFECTS OF DAMAGE

Damage to propulsion or reactor systems limits speed. Rudder damage affects turn radius, and damage to planes or ballast reduces their efficiency. Hull damage impacts crush depth and flooding, with no in-sea repairs possible.

## STEERING

Steering the vessel is accomplished using A and D. Rudder settings have increments from -30 degrees (left) to +30 degrees (right), affecting turn performance. Desired headings can be plotted on the tactical map.

## DEPTH CONTROL

Dive planes (W and S) and ballast (C and E) are employed for depth control. Various methods, including the dive panel, allow setting depth. Emergency commands, such as Emergency Blow and periscope depth, enhance maneuverability.

## TEST & CRUSH DEPTHS

Submarine hulls are constructed to endure water pressure. Test depth is the safe operating depth, while crush depth is the point of structural failure. Damage to planes or ballast affects surfacing and diving efficiency.

## STRAIGHT & LEVEL

X sets rudder, planes, and ballast to 0. This command aids in maintaining a straight and level course.

## COLLISIONS

Collisions with ice or land result in speed loss. Speed at impact determines damage severity. Shallow waters prompt notifications, and collisions disable time compression until the submarine is clear.

## NAVIGATION ICONS

Status icons warn of navigation hazards, time compression, event camera focus, cavitation, silent running, shallow depth, ice hazard, and mine hazard during navigation.
