Solid State Gyros and Related Systems
Improved attitude and direction information is always a goal in aviation. Modern aircraft make use of highly accurate solidstate attitude and directional devices with no moving parts. This results in…
Principles of Gyroscopic Instruments
Mechanical Gyros Three of the most common flight instruments, the attitude indicator, heading indicator, and turn needle of the turn-andbank indicator, are controlled by gyroscopes. To understand how these instruments…
How Maintenance of Navigation Lights is Done On Ships?
In spite of the latest advancements in maritime navigation technologies such as GPS, ECDIS, and several other satellite signaling systems, navigation lights still play an important role in navigation of ships…
Twin-Engine Aircraft Vacuum System Operation
Twin-engine aircraft vacuum systems are more complicated. They contain an engine-driven vacuum pump on each engine. The associated lines and components for each pump are isolated from each other and…
What is Alternate Marine Power (AMP) or Cold Ironing?
Alternate Maritime Power or AMP is an anti-pollution measure which helps in reducing air pollution generated from diesel generators by using shore electric power as a substitute. AMP is used…
Typical Pump-Driven System
The following components are found in a typical vacuum system for gyroscopic power supply. A brief description is given of each. Refer to the figures for detailed illustrations. Air-oil separator—oil…
Alternator Maintenance on Ships
An alternator is an electro-mechanical device comprising of stator, rotor winding and an external exciter for supplying excitation voltage. Alternator generates electricity when coupled with a prime mover. Alternator on…
Busbar Maintenance on Ships
A busbar is a copper plate/bar, which is used, in ship’s m in and emergency switch boards to conduct electricity from generators or from one electrical terminal to another. Technically,…
Engine-Driven Vacuum Pump
The vane-type engine-driven pump is the most common source of vacuum for gyros installed in general aviation, light aircraft. One type of engine-driven pump is geared to the engine and…
Starter Panel Maintenance on Ships
Dozens of motors are used on board ships for a variety of purposes in both deck and engine departments. Each of these motors has its dedicated starter panel, which is…
