key-for-inventory-planning-every-airliner-should-focus
KPIs, or Key Performance Indicators, are units of measurement that allow businesses to track their success and evaluate how effectively they are achieving their objectives.  When choosing which KPIs to use, utilize the SMART acronym.

A. Specific – Are your objectives clear?
B. Measurable – Can you quantify your objectives?
C. Attainable – Are your objectives realistic?
D. Relevant – Are your objectives related to your overall business?
E. Time – In what amount of time do you expect to meet these objectives? 

Inventory planning is a must for any airline housing spare parts for maintenance purposes.  Airlines don’t want to deal with an extended AOG situation resulting from a lack of parts, but it’s unrealistic to house a whole aircraft’s worth of spares that may, or may not, be needed. Five important KPIs regarding inventory planning capabilities that every airline should focus on include the following.
  1. Inventory Turn - Stock being issued/overall inventory value= Inventory Turn. Usually low, parts don’t typically fail that often.  It may be beneficial to sell or exchange parts, which are slow-moving, rather than have them sit in inventory.
  2. Inventory Per Tail - The amount of inventory you have, per aircraft.  Some aircraft have more expensive parts than others, so be sure to keep aircraft type in mind.
  3. Inventory Investment - Includes all operational/capital spending (repair costs, holding costs, etc.).  Budgeting for this really depends on demand– flight hours, upcoming maintenance checks, and busy seasons should all be factored into this.
  4. Inventory Service Level - Determined by the level of stock you have sitting in your warehouse.  It’s the amount of time a part is available (where it is available, and for how long).
  5. Inventory Cost Per Hour of Flight - Operating costs/flying hours= Cost Per Hour Of Flight
    Remember it is important to consistently review, revise and reevaluate your KPIs.  As your business changes, so should your objectives and goals.

Importance Of Reed Relays in Electronic Field
First appearing in the 1930s, reed relays were once a critical component of telecommunications systems. Despite phasing out of telecommunications, they are now more prolific than ever as they find use other applications such as automatic test equipment, electronics, etc


Reed relays are relays with contacts made of a magnetic material with electromagnetics that act directly on the switch inside of requiring an armature. This relay contains a reed switch, an optional diode, an encapsulating package with connection terminals, and a coil for creating a magnetic field. When used correctly, this type of relay is a perfect device, especially since it has inherent isolation between voltage controls and operating coils. This type of mechanism allows for a flawless signal switching.

The reed switch, a component within the relay, has two metal shaped blades created from highly magnetic material. These blades are encapsulated inside a glass tube, making them resistant to corrosion. This glass seal also protects debris from entering the switch, allowing for a lengthy mechanical life.  Due to their magnetic nature, the blades are attracted to each other and with enough of a push, the blades will touch, forming an electrical contact. These two blades are the only point of contact within the switch.

Reed switches have many different varying factors, one of which is size. Longer reed switches do not require long-distance blade deflection, allowing for the blade gap to be closed more easily. Shorter reed switches are typically made with thinner materials to allow for easier blade contact.  These small switches allow for small relays to be constructed, a critical aspect when space is an issue. Reed switches are used to generate electricity in a circuit. The generation of electricity inside a circuit is critical, making reed switch a necessity to operate to anything with a circuit board such as an aircraft or a vehicle.

how-aircraft-engines-work
Aircraft engines and car engines seem like they would be rather similar. After all, they are both machinery that power massive vehicles used to transport people and goods. But, the truth is, aircraft engines are rather different. Aircraft utilize RPMs, not multi-gear transmissions.

RPMs are like gears in a car, in the sense that propeller driven aircraft depend on specific RPM, or revolutions per minute, settings to achieve different stages of flight. So, the RPMs are at maximum setting during take-offs and landing, and they are reduced to a slower and more efficient setting during flight. During flight, the aircraft engine’s RPM doesn’t change, but the engine power, which translates to speed, can.
 
Aircraft engines have three major controls: the throttle, the propeller knob and the mixture knob. While the throttle is like the gas pedal of a car in terms of increasing and decreasing power, it’s different in that the aircraft engine still runs at the same speed even as the throttle changes the power output. That’s because the propeller knob changes the RPMs. When the aircraft takes-off, the propeller knob and the throttle are set to full forward for maximum power. But at cruising altitude, the throttle is set to reduce the power output and the propeller RPMs accordingly. The mixture knob is then used to lean the fuel-air ratio to the proper stoichiometric ratio for that particular altitude so that the aircraft flies smoothly.
 
Notice, to reach cruising speeds, only the throttle and the mixture knobs need to be changed. But the aircraft can still speed up or slow down. The propeller knob doesn’t have to move, and the RPMs don’t have to change. That’s because speed is based on the power output by the throttle, and how propeller blades automatically change pitch, or the distance it would move forward if it were cutting through a solid, accordingly.
 
Clearly, aircraft engines and car engines are not that similar or comparable. You don’t have to deal with altitudes, stoichiometry of fuel-air ratios, or pitch when you drive a car. But, like a car, you do have to maintain your engine and repair and replace parts when need-be. At times like that, you have ASAP Purchasing, owned and operated by ASAP Semiconductor, one of the premier suppliers of aviation parts and components ranging from massive engines to tiny bearings.

autonomous-vehicles-on-the-rise
Autonomous cars are self-driving vehicles. It is very interesting to see how long we have come from having a basic mode of transportation which has slowly but surely evolved into much more than that. A handful of the automobile industry has slowly transitioned into building their first autonomous cars. Companies such as Mercedes-Benz, Cadillac, Audi, and of course Tesla electric have many of them on the road today. However, owing to the nature of the advancement there are still many errors to fix due to possibilities of crashes and potential deaths as seen by Tesla Model S as the first autonomous car fatality. It is important these vehicles can detect objects, fog, and all the hazards of the road 100% of the time before progressing any further.
Autonomous vehicles need Infrared cameras to allow better visibility than light-based cameras. Although there is a limitation due to the high cost and limited resources available. Now the time has gone into research to find a different solution that will enable an overall better technology for the vehicle.
The University of Southern California, University of Wisconsin, the Air Force Research Lab and the University of Missouri collaborated to create a new material that enables better-infrared technology. This new material is called chalcogenide perovskites. This was found in barium titanium sulfide (BTS) which cooperated uniquely, where the light interacted in two different directions. The BTS would make for better image contrast which well helps better improve sensing objects. This new technology will improve and advance the technology behind autonomous vehicles efficiently at a better cost.
