Frequently asked questions

 

Why should I replace the existing display units on my aircraft?

The DU-870 cathode ray tube display units are no longer supported by the only authorized repairer Honeywell with repairs of failed units being ceased at the end of 2016. With the support and repair discontinued, the DU-870 exchange unit availability will decrease significantly as the exchange pool of units is used and not replenished. This will ultimately increase the possibility of having an AOG situation involving a display unit with no DU-870 availability.

 

Are there any wiring changes required for the drop-in DU-875 Display Unit replacement?

There are no wiring or aircraft modification changes required for the drop-in DU-875 replacement, the original display is simply removed and replaced with the new LCD display unit and can be done simply in the field if required.

 

I have purchased the EASA/FAA drop-in STC to replace a failed display unit prior to the release of the enhanced feature STC, do I need to purchase the enhanced feature STC also?

No, When you purchase the JetCity Engineering EASA/FAA Drop-In STC you will automatically have your aircraft added to the enhanced feature STC permission list and have the required installation documentation forwarded to you following STC approval.

 

I have purchased a drop-in DU-875 screen to replace one of my failed DU-870’s. Can I still use this screen for the enhanced upgrade when I choose to complete the upgrade?

Yes, the DU-875 drop-in display unit (P/N K9321060A14) can be upgraded by an ‘on the wing’ software upgrade to DU-875AF P/N K9321062A11 that will allow installation as part of the enhanced feature upgrade.

 

Are there any special promotions available for display unit purchase?

Honeywell are currently offering a trade-in credit of USD$40,000 for each DU-870 that has been guaranteed through to the end of 2017 when a DU-875 is purchased as a replacement unit for a Learjet 45. As the EASA/FAA STC holder, JetCity Engineering are offering special package pricing. For information contact Mr. Travis Stephens
