When reverse pitch propellers is used?

Reverse pitch propellers are used primarily in marine vessels and aircraft to improve maneuverability during landing and docking. By adjusting the pitch of the propeller blades to direct thrust in the opposite direction, these systems help slow down the vessel or aircraft more effectively. This capability is particularly beneficial for larger ships and planes, allowing for shorter stopping distances and enhanced control in tight spaces. Additionally, reverse pitch can aid in reducing the risk of damage to the vessel or surrounding structures during docking operations.
