We’re back! And you’ve been busy operating a tip-top apple sorting company. We knew you could do it.

And you’ve already come a long way! It looks like all of your troubleshooting techniques and methodologies have been optimized to the point where four technicians can service 100 apple sorters. Your operation is humming along.

If any of this sounds at all confusing, check out Part 1: Troubleshooting to get up to speed!

Now you want to expand your sorting output by 25% but aren’t quite sure how. …

Employment Opportunities Beyond The Front Lines

This article is written with the Aircraft Maintenance Technician (AMT) as a focal point. Prior knowledge of aircraft maintenance practices and operation are recommended for a deeper understanding of the concepts described. If you’d like a refresher on the basics of being an AMT, read this first:

As the effects of COVID-19 rage on and airlines downsize their fleets, there are growing concerns regarding job security and career progression within the industry. So recently, we’ve fielded a lot of questions from AMTs about employment opportunities outside of direct aircraft maintenance.

Picture This

You’re sitting on your flight, the plane doors have closed, you’re about to push back and take off for your much deserved vacation; you settle in and all of a sudden… “this is your captain speaking, we have a small technical issue here on the flight deck, we’re checking it out and we’ll have you on your way shortly.” The doors reopen, and that airline employee in the reflective vest boards the aircraft with tools and whatnot. As a passenger you hate this employee — every time you see that vest, it means your flight isn’t going anywhere (on time).

But who is the person in the vest? …

Understanding System Troubleshooting

At Aermetric, one of our primary objectives is to help aircraft technicians troubleshoot more effectively. In order to do that, before we write algorithm after algorithm in the predictive realm, we needed to modernize and reapply the basic ideologies of troubleshooting. What are those basic ideologies and what do they mean in the real-world? Let’s take a look.

What is troubleshooting?

The dictionary defines it as “tracing and correcting faults in a mechanical or electronic system.” From this definition alone, a few major points can be deduced:

1. The system that we’re about to correct isn’t working per its design criteria. It isn’t broken per-say, but something in its current operation has veered off course from the intended use. …

Dissecting Airline Profit Models in the Midst of a Pandemic

It’s mid-April and the United States is feeling the full effect of the Coronavirus (COVID-19). Businesses have been closed for over a month, “non-essential” workers have been sent home, and people throughout the country are sheltering in place. We’re avoiding large crowds and unnecessary trips outdoors, waiting for the pandemic to end and for life to go back to normal.

The big question we’re asking ourselves at Aermetric HQ, though, is “what is that new normal?” With U.S unemployment rates exceeding 20% — the highest it’s been since the great depression era — and talk of a potential economic depression, how are businesses going to survive, let alone thrive? Are consumers going to value the same things? …

What is an Aircraft Health Monitoring System?

Using commercial airlines as an example, let’s start by examining what an aircraft health monitoring system (HMS) is and what current HMS solutions are lacking.

What is an HMS? At every airline there are portals for teams to modify and observe various aspects of daily operations. For example, there is an application that allows for the routing and rerouting of commercial flights and another application that manipulates the workloads against an aircraft’s servicing needs. These different portals work within an airline to ensure that flight operations move smoothly 24/7, 365 days per year.

Over the past few years the need for a new technical portal has emerged — the health monitoring system (HMS) — which gives insight into an aircraft’s technical operating health live and in real time. …

Transmitting data to and from aircraft has been around since the inception of commercial flight as voice communication is imperative for basic aircraft navigation and operation. In the last few decades, however, data transmission started to come into the lime-light as a flight necessity.

In order to accurately explain aircraft data transmission architecture, we’ll need to break up the process into separate sections: Data Source, Data Aggregation, Data Transmission.

Data Source:

On board the aircraft, the source for parametric data is the individual sensor while the source of text data is the flight crew.

When sending and receiving data to and from an aircraft the two most general sources are either the aircraft itself or a ground station. …

Two Major Airplane Crashes in 5 Months Lead to Questions of Airline Safety

With two major airplane crashes occurring within 5 months of each other — Lion Air in October 2018 and Ethiopian Airlines in March 2019 — we’ve been getting many questions about airline safety and what these crashes mean for the future of regulation (read more about that here). The main question people ask is, plainly, is it safe to fly? The short answer is yes.

Let’s look at why.

Land, Air, or Sea? Aviation Remains the Safest Form of Travel

An air disaster sends a shockwave through international media unlike most other events. Besides the deeply saddening loss of human life, it represents a breakdown in a travel medium billions of people rely on to move from place to place. Yet, while these disasters are jarring to say the least, aviation remains the safest method of travel worldwide, eclipsing sea, rail and automotive. …

The World Waits to See How Regulators Will Respond to Recent Boeing Crashes

In the wake of the recent Lion Air and Ethiopian Airlines crashes, multiple publications have reached out to Aermetric to inquire about our position on US regulatory bodies and airline safety. Below are the most asked questions and our answers.

What do you expect from the Congress hearing about the FAA? Has the FAA gone too far in allowing Boeing to regulate itself?

There is a fine balance between the notion that Boeing is self-regulating and giving the government too much control over a private product, in this case the Boeing 737 MAX. As any product in any space, there are regulations put forth by the government that the product needs to be designed to. For example, the MAX was created for the pre-existing regulations set up by the FAA for commercial aircraft. …

How legacy maintenance programs are holding airlines back

Technical Services Interruptions Cost Airlines Billions of Dollars Annually

The business goal for an airline is to have aircraft in the air with little to no downtime in order to maximize revenue — especially in a price sensitive market with margin pressure. However, when problems with aircraft occur, because of the dated, fragmented systems being used for diagnosis, it’s difficult to respond to failures in a coordinated, timely response. The current method is strikingly ineffective and simply can’t support the rising consumer demand for flights, resulting in far too many service interruptions.

Legacy Troubleshooting Costs Billions

Legacy maintenance relies heavily on scheduled checks. Presently, aside from ensuring an aircraft is safe for flight, scheduled checks are necessary to keep aircraft reliable and flying as much as possible. These scheduled checks are mandated by aircraft manufacturers based on failure predictions of specific parts and systems aboard an aircraft. When parts fail outside of the routine maintenance a service interruption occurs causing a flight delay or cancellation. These technical service-interruptions directly account for a loss of roughly $1.5 billion annually, with potential indirect losses in the $10s of billions. Total service interruptions to US airlines alone account for a loss of $8 billion annually, with ripple effect loss of $31 billion to passengers and the US economy, and immeasurable loss of goodwill among commercial passengers. …
