To better understand the use and importance of alternators, we will discuss them in more detail below.
The landing process for airliners is intensive, requiring enough stopping power to slow an aircraft upwards of 127,000 pounds while it touches the ground at a speed of 160 mph. Nevertheless, it is a standard procedure that most aircraft can conduct with ease, thanks to ample training and various braking systems and components that are situated across the assembly. While an automobile or another similar vehicle may only require wheel braking systems to come to a stop, the standard jet-engine aircraft will utilize disc brakes, wing spoilers, and reverse thrust to effectively slow themselves. In this blog, we will talk about these three braking methods and how they each function, allowing you to have a better understanding of the landing process.
Knots, or nautical miles, are a unit of measurement used in aviation; however, the use of this system originates from early sea voyages. At sea, as well as in the air, there are no landmarks or significant indicators of distance. Of course, as technology advanced, other units of measurement became available to non-land-based travel, but knots are still used when measuring aircraft speed for a handful of reasons. On top of being an easy and familiar way to navigate in flight, the International Civil Aviation Organization (ICAO), recommends knots as the preferred unit of airspeed measurement. Today, the knot is a much more precise unit of measurement than it was at the time of its advent, but this blog will cover a brief history of airspeed knots as it provides insight to current flight practices.
A transistor typically regulates the flow of voltage or current by serving as a gate or switch for all incoming electronic signals.
