The Vertical Speed Indicator (VSI), one of the simplest yet most important instruments at a pilot's disposal, is a tool used to indicate the rate of climb or descent of an aircraft. The VSI uses the common pitot-static system to determine vertical speed and displays the result via a needle and circular scale instrument. In this blog, we will take a look at VSIs, what components they are made of, and how they work.

Set classifications for common types of aircraft damage ensures uniform diagnoses and accurate repair for all aircraft overhauls. There are eleven detailed aircraft damage classifications starting with the basic, dent. A dent is classified as a depressed or hollow deformation without removal of material or change in cross sectional area. Dents like these are caused by impact from a smoothly contoured object.

Aircraft maintenance is becoming more complex with the passing of time and scheduled inspections are more important than ever. A scheduled aircraft inspection refers to any preventative repair or maintenance that a cabin crew or technicians undertakes at planned intervals. The main types of scheduled maintenance are annual inspections, 50- and 100-hour inspections, preflight checks, and progressive inspections. These are all designed to ensure the functionality and airworthiness of the aircraft.

Short answer: yes. Long answer: they typically don’t.

Every so often, the folks at Buy Aviation Parts get someone asking just how many engines does an aircraft really need, and oftentimes, they’ll be surprised to know that most aircraft (even those equipped with only two engines) can take off, climb high altitudes, and land with just one. A little known fact is that the majority of engines are specifically engineered to function with the use of only one engine. So why add any more? A simple reason is that the more engines a plane has to fall back on, the better. Should one engine suddenly stop functioning, then the plane can still fly with a backup of one or two engines.

According to safety statistics, less than one in every one million flights will have an engine failure, meaning there is a very small chance for engine failure to occur. As reassuring as this number is, aviation laws will always account for emergency situations even if the chances of it actually occurring are rare. In the event of such an occurrence, the pilots will disengage the auto throttle in order to stop automatic thrust control, reduce the thrust on the engines and leave it on idle, and finally, switch off the fuel control switch so as to stop fuel flow to the engine that is malfunctioning. 

Depending on the aircraft that will be flown, some engines may require as much as four engines. Though it is not necessary to utilize all of them, commercial aircraft will typically fly with four engines as per FAA standards. Private planes, meanwhile, will usually utilize only two. For any questions on engines or other airframe structural components, contact the team at Buy Aviation Parts. They can provide aircraft propellers, engines, and detailed information on such components.

For much of the U.S., de-icing is a necessity of flying during most of the year. While it might be annoying for passengers to wait on the plane as the de-icing fluids wash over the plane, it’s a serious task for flight crews. Ice causes a great deal of concern from an operational safety perspective and every precaution must be taken before a plane can depart. In early 2018, Southwest Airlines was forced to cancel over 200 flights due to a shortage of de-icing fluid.

When purchasing parts for your military or aircraft equipment, it should be a top priority that these parts are sourced from a reliable supplier.

Adhering to proper maintenance practices is of utmost importance in the aerospace industry. No aircraft is so tolerant of neglect that it is exempt from deterioration in the absence of inspection and maintenance programs. Corrosion, wear and tear, natural fatigue, and chance failures all contribute to the overall functioning and safety of aircraft.

Much thought and focus are given to developing and improving the tools with which aircraft maintenance is performed, but what about the procedures that govern how those tools are used? Process-driven actions on the hangar floor or general aviation facilities don’t have to be cumbersome or complex.

If given a diagram of an aircraft, many people could confidently label the wings, nose, tail, and perhaps the aircraft engine. When tasked with identifying such components as the empennage or power plants, their confidence levels may dip. There a few key components that make up the aircraft design that is universally recognized.

A bearing is a device that supports the rotational and linear movement, bears various loads and stresses, and reduces friction. The application of bearings has been seen throughout history, predating the wheel, but over the last century, its designs have become much more advanced.
