A pilot ladder is a highly specialized form of rope ladder, typically used on board cargo vessels [1] for the purposes of embarking and disembarking pilots. The design and construction of the ladders is tightly specified [2] by international regulation under the SOLAS regime. Pilot ladders and other boarding arrangements must be carefully ...
A pilot ladder has specific regulations on step size, spacing and the use of spreaders. It is the use of spreaders (long treads that extend well past the vertical ropes) in a pilot ladder that distinguishes it from a Jacob's ladder. When not being used, the ladder is stowed away, usually rolled up, rather than left hanging.
A standard holding pattern. Shown are the entry (green), the holding fix (red) and the holding pattern itself (blue) In aviation, holding (or flying a hold) is a maneuver designed to delay an aircraft already in flight while keeping it within a specified airspace; i.e. "going in circles."
Typically, the pilot joins an incoming ship prior to the ship's entry into the shallow water at the designated "pilot boarding area" via helicopter or pilot boat and climbs a pilot ladder, sometimes up to 40 feet (12 metres), to the deck of the largest container and tanker ships. Before climbing the pilot ladder, the pilot performs a visual ...
A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...
Wall-mounted electromagnetic door holder securing a door in the open position. An electromagnetic door holder (electromagnetic door holder and release or hold-open device, sometimes informally called a mag hold open or electric doorstop) is a simple electromechanical mechanism which can be used to hold a fire door or security door open until given a signal to release.
Electropermanent magnets made with powerful rare-earth magnets are used as industrial lifting (tractive) magnets to lift heavy ferrous metal objects; when the object reaches its destination the magnet can be switched off, releasing the object. Programmable magnets are also being researched as a means of creating self-building structures. [2] [3]
The Celestial Voyages historical science fiction series by Jeff Provine uses magnetic boots as the main sense of balance in its Edwardian starships. In the Ratchet & Clank series, one of the gadgets is a pair of "Magneboots", which are used to traverse special ventilation shafts in the first installment of the series Ratchet & Clank.
