ADS-B And Non-Performing Emitters

Posted by Duncan Download Blog on Tue, May 01, 2018 @ 07:00 AM

According to the most recent data from the FAA (Federal Aviation Association), slightly fewer than 10% of all U.S. registered ADS-B (Automatic Dependent Surveillance Broadcast)-equipped aircraft are NPE, or non-performing emitters. Having NPE means the aircraft’s ADS-B Out system is not transmitting in compliance with FAR (Federal Aviation Regulations) 91.227.

Here are some common issues that result in having NPE:

  1. Incorrect software version or improper system configuration can result in reduced aircraft position integrity/accuracy.
  2. Incorrect emitter category results when the aircraft’s ADS-B system is transmitting the wrong emitter category based on its maximum take-off weight.
  3. Incorrect Flight ID is a result of the aircraft registration for Mode S not matching the Flight ID.
  4. Transmitting airborne data while the aircraft is on the ground.

Is Your ADS-B Equipment Compliant?  

adsb videoGo to FAA Website: https://adsbperformance.faa.gov/PAPRRequest.aspx and request a PAPR (Public ADS-B Performance Report). A PAPR provides an additional method of verifying proper operation of ADS-B equipment.

After answering a few questions about your ADS-B installation, you will receive a report from the FAA showing what parameters have failed, if any. Instructions and a User’s Guide can be found on the website.

If you have not complied with the upcoming FAA ADS-B mandate, the time is now. For more information, go to: www.DuncanAviation.aero/adsb

Duncan Aviation Manager of Satellite Operations Pens ADS-B Article

Posted by Duncan Download Blog on Tue, Apr 24, 2018 @ 07:00 AM

If aircraft are sitting on the ground after the deadline, they aren’t useful to anyone.

For the April 2018 issue of AvBuyer magazine, Matt Nelson Manager of Satellite Operations at Duncan Aviation wrote the Guest Editor’s ViewPoint. There are about 20 months remaining until the FAA’s December 31, 2019, deadline to upgrade aircraft to ADS-B (Automatic Dependent Surveillance-Broadcast), and Matt wants to reiterate Duncan Aviation’s message regarding ADS-B.

Qualified Shop With Experienced Avionics Technicians

adsb-fleet_completeIt’s important to get the upgrade done at a qualified facility. Counting installations performed before 2017, Duncan Aviation has completed more than 520 ADS-B installations to date, and has capacity for another 1500 by the mandate deadline. We consider our organization to be the foremost ADS-B compliance experts across all aircraft makes and models.

Qualified shops around the United States are making a dent in the numbers; it’s estimated that roughly 40% of the fleet has been upgrade. Matt pointed out that Duncan Aviation and other MROs are trying to let our customers know that aircraft in need of ADS-B upgrades are going to be vying for available space in the remaining 20 months. In fact, the monthly rate at which the remainder of the fleet needs modification is 390 aircraft, and the current rate is 190 aircraft per month. As we get closer to the deadline, there will be an increasing shortage of hangar space and qualified shops with experienced avionics technicians.

Hangar Space

In 2017, Duncan Aviation’s nation-wide network of Satellite facilities allotted space and labor for 300 upgrades. Because our technicians gained proficiency with every installation, the shops increased their capacity to 460 installations in 2018 and are planning for nearly 600 in 2019.

At several of the Satellite Avionics Shops Duncan Aviation’s customers are taking advantage of the proximity of our skilled technicians and having their entire fleets upgraded.

Deadline Firm

deadline-graphic2We’ve been repeating this message for several years: Upgrade now, please don’t wait until the last minute; the deadline isn’t going to change, and parts and labor prices are not going to drop. We really want to reiterate that there are no magic bullets on the horizon for your ADS-B upgrade. The OEMs have spent millions of dollars developing solutions for their platforms, and they aren’t going to develop anything with a lower cost or that’s easier to install in the final months before the deadline. In fact, most vendors have already announced price increases for this year and next.

We also want to make sure that the industry understands our objectives in light of the mandates in general. Our objective is to ensure that our customers become compliant by the deadline in order to keep their aircraft flying. If aircraft are sitting on the ground, they aren’t useful to anyone.

The Duncan Aviation Red Phone

Posted by Duncan Download Blog on Tue, Sep 26, 2017 @ 09:00 AM

phonebooth-15_small.jpgDuncan Aviation will have video phones in its NBAA booth to connect visitors with experts who stayed home. 

Although Duncan Aviation will have about 25 representatives available to visitors at its NBAA-BACE (National Business Aviation Association’s Business Aviation Convention & Exhibition)booth #C9125, there is no doubt that they will be asked about team members who didn’t make the trip. With more than 1,250 team members who develop strong relationships with customers, vendors and partners, it would be impossible for Duncan Aviation to bring everyone with close contacts at the show.

To make it easier for these visitors to reach out to team members not at the show, Duncan Aviation will have two video phones in its booth that will be connected to Duncan Aviation’s phone system and ready to provide video calls with experts back home.

In addition to satisfying this social aspect of the NBAA show, the phones will be available if area experts in the booth are working with other visitors and unable to connect with someone who stops by.

“ADS-B and connectivity are hot issues again this year ,” says Lori Johnson, Duncan Aviation’s Marketing Communications Manager. “In year’s past, there has been a line of visitors waiting to speak with our avionics representatives. This will allow them to reach out and get answers faster than waiting while still having a face-to-face conversation.”


For more information, visit Duncan Aviation at booth #C9125 during this year’s NBAA convention from October 10-12, at the Las Vegas Convention Center at the Henderson Executive Airport in Las Vegas, Nevada, or watch for announcements at the Duncan Aviation NBAA-BACE webpage.

Duncan Aviation Releases a Different Kind of Falcon

Posted by Duncan Download Blog on Thu, Aug 17, 2017 @ 09:00 AM

Falcon release.jpg

Earlier this summer, three American Kestral Falcons attempted to take their maiden flight out of the nest that was high in the rafters of a Duncan Aviation maintenance hangar. Unfortunately, they didn’t make it far and landed on the floor. 

They were discovered, rescued and taken to the Fontenelle Forest Raptor Recovery Center in Elmwood, NE, where Elaine Bachel, center volunteer, fed and cared for them.

The Raptor Recovery Center sees between 450-500 birds of prey, such as eagles, falcons, hawks, owls, and vultures, in need of immediate assistance every year. They rely on concerned citizen to report the injured raptors and a network of dedicated volunteers across the area to receive the calls and then potentially drive countless miles to retrieve the birds and get them back to the trauma care unit. The birds are evaluated immediately upon arrival and if necessary, provided treatment, medication, and surgery by trained professionals. Once the birds are healthy again, they are banded and released back to the wild near where they are found.

Elaine said the falcons discovered at Duncan Aviation were uninjured and just needed a little bit more time to grow and get stronger. After only a few weeks, she brought the birds back to Duncan Aviation where some of the technicians who found them were able to release them.

Another Sucessful Year at EBACE 2017 for Duncan Aviation

Posted by Duncan Download Blog on Thu, Jun 01, 2017 @ 12:30 PM

They say the business of business aviation happens at EBACE (European Business Aviation Convention & Exhibition). No where did that happen more than the Duncan Aviation booth. 

Over three days during EBACE 2017, hundreds of attendees stopped by to say hello, giving our team the opportunity to connect with customers, business partners and friends. We value this time to strengthen established relationships and forge new ones. 

According to the EBACE website this year's show occupied more than 40,000 square-meters of exhibit floor by more than 400 exhibitors. The static display featured 56 business aircraft. EBACE 2017 attendees came from more than 100 countries, from the European region and beyond.

We had a lot of fun. Hope you did too. Have a look at our EBACE 2017 photo album below.

Aircraft Compass System Alignment Formulae

Posted by Duncan Download Blog on Tue, May 02, 2017 @ 11:33 AM

If you replace or change the magnetic compass or components on your aircraft’s compass system, it is appropriate to swing the compass to verify or align it to minimize errors.

The following alignment steps apply to all make/model aircraft and are based on MIL-STD 765A. Your aircraft’s compass system may have different methods of alignment. Always refer to and use the manufacturer’s procedures if they differ from this method.

Formulae:

North (N) / South (S) Correction = ½ [N error - S error]

East (E) / West (W) Correction = ½ [W error - E error]

Index Correction =

¼ [N error + E error + S error + W error]

Compass Swing Procedure with example:

South

  1. Align the aircraft to the South magnetic heading (180°) per the compass rose
  2. Note the indicated heading (Example: 175°)
  3. Note the deviation error (-5)
    1. Positive (+) if greater than 180° and negative (-) if less

West

  1. Align the aircraft to the West magnetic heading (270°) per the compass rose
  2. Note the indicated heading (Example 276°)
  3. Note the deviation error (+6)
    1. Positive (+) if greater than 270° and negative (-) if less

North

  1. Align the aircraft to the North magnetic heading (0°) per the compass rose
  2. Note the indicated heading (6°)
  3. Note the deviation error (6)
    1. Positive (+) if greater than 0/360° and negative (-) if less

East

  1. Align aircraft to the East magnetic heading (90°) per the compass rose
  2. Note the indicated heading (90°)
  3. Note the deviation error (0)

Swing Results

              Actual        Indicated     Deviation error

N             000                 006                        +6

E             090                 090                        +0

S             180                 175                        -5

W            270                 276                        +6

N/S Correction = ½ [N error - S error]

= ½ [(+6) – (-5)]

= ½(+11)

= +5.5° error

Align the aircraft to 5.5° indicated and adjust the N/S correction to read 0° indicated

E/W Correction = ½ [E error - W error]

= ½ [(+0) – (+6)]

= ½(-6)

= -3° error

Align the aircraft to 87° indicated and set E/W adjustment to read 90°                                                                            

Index Correction = ¼ [N error + E error + S error + W error]

= ¼ [(+6) + (+0) + (-5) + (+6)]

= +1.75° error

Align Flux Valve to subtract 1.75° from existing indicated heading

If you have any questions about this procedure, feel free to reach out to Duncan Aviation Avionics Instrument Tech Rep, Curt Campbell.
