Honeywell N1 DEEC for Citation VII
— Duncan Aviation's Doug Alleman and Honeywell's Steve Kirsh
Honeywell has begun work on its N1 Digital Electronic Engine Control (N1 DEEC) for the Cessna Citation VII aircraft and expects to receive certification approval by September 2002.
The N1 DEEC reduces pilot workload with improved power management and engine temperature limiting. Control trimming has been eliminated, and the added diagnostic capabilities significantly reduce maintenance labor costs.
Honeywell's N1 DEEC is easily installed on an aircraft in the same location as the existing electronic engine control with no wiring harness changes.
Aircraft equipped with TFE731 engines that are covered by a Honeywell Maintenance Service Plan (MSP) will be fitted with the N1 DEEC at no charge, at the time of a Core Zone Inspection (CZI) or when existing controls require removal or replacement. Honeywell is offering N1 DEECs to non-MSP customers at a special exchange price for the current control.
For more information on the N1 DEEC contact Doug Alleman by phone, 402.479.4236.
Cabin Communications
— Clark Gordon
Starting September 1, AT&T Wireless (Claricom) will no longer offer air-to-ground telephony (flight fone) service to general aviation aircraft. The telephony system hardware was formally sold by Bendix/King as the Flight Fone 800, FF800. Though there are no direct "plug and play" replacements for this system there are several alternatives, such as Teledyne MagnaStar, AirCell AGT.02, Aero M or Aero I, Iridium, AirSat 1.
Some questions to consider when selecting a replacement are: Is one independent channel enough or will you require two channels? Is domestic coverage (North America) enough or will you require international coverage? Will you want the new system to interface with an existing system, SatCom, Universal Un-Link, AFIS, etc.?
Duncan Aviation can help you select a replacement system that best fits your flight mission and communications needs.
Garmin GNS-430/530 Update
— Curt Campbell
We would like to announce that Duncan Aviation-Battle Creek has successfully installed a dual Garmin GNS-430/530 GPS/Nav/Com interfaced with a Honeywell FZ-500 flight control system in a Citation 551 aircraft. The Garmin GAD-42 Adapter was used, and the Honeywell flight control system was upgraded to accept roll steering.
As reported in an earlier Duncan Intelligence newsletter, previous field reports from operators indicated an incompatibility between the Garmin and the Honeywell Flight Director systems. However, no compatibility issues were encountered during Duncan Aviation's installation.
With the Cessna RVSM service bulletin and the GPWS that was also installed during the visit to Battle Creek, this aircraft is ready for the future. The Garmin radios provide 8.33kHz channel spacing, FM Immunity and are BRNAV (RNP-5) capable.
RVSM Reminder
— Joe Austin
Even though the requirement for RVSM in the United States is not until 2004, we suggest to you don't wait until the deadline. RVSM certification is not something that can be quickly accomplished at the last minute. We suggest that you comply with the Cessna bulletin at your next major maintenance downtime. There will be thousands of planes looking for the certification before 2004; some advance planning on your part will avoid scheduling hassles and possible altitude restrictions.
