The Hidden Costs of Maintaining Outdated Avionics

King Air C90B

With many companies currently budgeting for 2016, it’s important to consider some of the hidden costs of maintaining outdated avionics, specifically old CRT (tube) EFIS displays. CRT display manufacturing is becoming obsolete and will inevitably become non-existent. This means that the pricing for these units is going to increase substantially and the availability is going to continually decrease. Let’s take King Airs as an example.

Avionics Maintenance Costs

By current market pricing, typical yearly costs just to maintain a Collins Pro Line 2 equipped King Air is about $20,000 per year. If you plan on keeping the aircraft for another five years under current market conditions and a traditional ADS-B mandate solution for about $75,000, you would be paying about $175,000 just to continue to maintain your current avionics package.

Traditional Upgrade

If you want to make additions to a Pro Line 2 avionics system, a WAAS/LPV upgrade would cost about $95,000 and RVSM would cost another $83,000. Combined with maintaining current avionics and ADS-B compliance, the total cost for five years of ownership with traditional upgrades is going to cost around $353,000. Not only are these costs high but these upgrades do not add value to your aircraft.

G1000 Upgrade

While an average base install of a Garmin G1000 in a King Air costs around $325,000, it adds an average value increase to your aircraft of around $275,000. In addition, it includes all of your upgrades like WAAS/LPV, ADS-B, RVSM and is safer, lighter, more reliable and can be completed in just 15 days.

Upgrade or Maintain

While some operators may choose to maintain their current avionics system, older avionics are becoming obsolete and will continue to increase in price and be less reliable. Your avionics system is critical to the operation and safety of your aircraft. An upgraded avionics system will ensure you are getting the most out of your aircraft.

The Reality of Parts Obsolescence – Avionics

Cathode ray tubes are commonly found in the Electronic Flight Instrumentation Systems of Beechjets, like this 400A.

Parts obsolescence is inevitable in aviation. The longer the aircraft has been in circulation, the harder it can be to find parts. This especially holds true in avionics because of the parallels they have with consumer electronics. The components that make up the avionics found in the cockpit weren’t originally designed for aviation; they were actually made for the average consumer. To build an Electronic Flight Instrumentation System (EFIS), avionics companies used technology developed for consumer electronics.

Unlike consumer electronics, airplanes are built to fly for many years. Consumer electronics on average have a life cycle of just a few years before something new comes out. As new technology is introduced into the market, old technology becomes obsolete. Consumer electronics have progressed rapidly, especially in the past ten years.

One example that is currently affecting many operators is the cathode ray tube, or CRT, most commonly found in Beechjets and airframes produced through the mid 2000’s. CRT’s were first introduced into airplanes around the 1980’s when microprocessors were coming of age. The simplified version of how the CRT works is that it uses high voltages to excite the screen phosphors within the tube and, in return, creates the picture. However, CRT’s are very susceptible to screen burn. If you can remember, old CRT monitors required screen savers as a preventative measure. If you left the same image on the screen for too long, it would burn the phosphor and leave a shadow of the image. When it came around to installing these CRT’s into the EFIS, specifically attitude and horizon, or HSI, level flights would show the exact same image for hours at a time, eventually burning the screen.

When CRT’s were readily available and plentiful, replacement wasn’t an issue. Consumers were still purchasing CRT TV’s and manufacturers were still producing replacement parts. In fact, Panasonic and Sony produced many of the CRT’s found in EFIS equipped airplanes. However, due to the rapid change in the consumer electronic market, CRT’s switched to LCD’s overnight. This caused the companies making the components for the CRT’s to shutdown and discontinue supporting the product. This is leading to obsolescence in replacement parts for all of the CRT EFIS equipped airplanes.

Avionics manufacturers predict that by the second half of the decade, replacement CRT’s will not be available to repair existing EFIS displays. Unfortunately, this leaves most owners and operators with little choice if they want to keep the same system. One option is to purchase a used EFIS display that was removed from a prior airplane, but that comes with the unknown of how long it will last. Another option is to spend a significant amount of money to send your parts to a specialist for repair at an increasing cost due to shortage of replacement components. Eventually, every CRT will possess significant screen burn. With performance standards gauging this, your airplane could eventually run the risk of being grounded.

Since there are a significant number of quality airplanes still flying, specifically the Beechjet, there will be a need for updated avionics. Engine parts should not be an issue because they don’t have a mass consumer market driving change. Current engine components work as designed and consumers aren’t forcing the need for new and faster components. But for avionics, there will be a point in time where you need to determine whether you want to keep flying the airplane and update the avionics or buy a new airplane.

Fortunately, there are several avionics retrofits available that will keep your plane flying long into the future. In fact, avionics manufacturers have been preparing for this by investing millions of dollars in research and development. For the Beechjet, Collins has updated their Pro Line series from the Pro Line 4 to the Pro Line 21. Additionally, Garmin introduced the G5000. Both of these retrofits are designed to significantly increase the capabilities of the airplane for the fraction of the cost it would take to purchase a new airplane.

Full implementation has yet to happen, but you can expect it within the next few years. The need hasn’t hit all owners and operators yet, but it’s beginning to trickle down. Inevitably, you will need to consider the available options.
