Cessna 185F Complete revamp of instrument panel.  This aircraft came to us from Ralph Cerretani of Cerretani Aviation group of Boulder Colorado. This modification is still in process however nearing completion. This modification consists of a total rebuild of the panel and the installation of the Aspen EFD1000Pro , Garmin GMA340 audio panel, SL40 Com tranceiver, GTX327 digital transponder an EDM 930 digital engine instrument and fuel quantity/flow display and a Garmin 696 with tilt panel dock.  this installation also included the replacement of all of the old white rocker style switches with the newer style breaker switch as found in the late model Cessna 172 and 182′s.  Satnan Avionics also completed the Annual inspection on this Cessna 185F in conjunction with the modifications.

Mark and Scott,

I wanted to thank you again for the work you did. The airplane was perfect all the way back. We even managed to figure a few thing out. No question its the coolest 185 panel in existence.

Installation of Aspen EFD1000PRO and Century 2000 Autopilot into Piper PA32-301T Saratoga owned by Shashi Kanth of Rapid City SD .  This installation consisted of removing the existion Century II autopilot and Gyros and installing the Century 2000 autopilot system which gave the aircraft the capability of pitch control such as altitude hold, and glideslope capture. The EFD1000PRO added the reliability of AHRS (Attitude, Heading Reference System)  which in turn fed the autopilot the heading information as well gave the autopilot GPSS steering capability from the flight plan of the GNS430W system.  Since the Saratoga’s annual was coming due Satnan Avionics completed the inspection in conjunction with the Installation keeping the aircraft down time to a minimum.

Total Panel Modification and GNS530W Installation with G600 Tilt Panel Dock in Beechcraft A36 Bonanza. This was a very cost effective way to put in XM weather and XM music into this A36 via the portable  Garmion 696 GPS. This aircraft is WAAS certified with the GNS530W.  The 696 panel dock is tilted toward the pilot for better viewing angle.

Single G600 Installation in King Air C90

Satnan Avionics completed this G600 installation in a King Air C90 aircraft. This installation required the removal of the Bendix King EFIS40/50 system and upgrading the present Garmin GPS400W system to a Garmin GNS430W system. In addition to the G600 and GNS430W upgrades a TAS615 traffic system was installed and displeyed on the G600 as well as the Avidyne EX500 MFD display and the GNS430W display. In addition this installation included XM weather XMD076 XM receiver and was displayed on the EX500 as well,.

Dual G600 Installation in King Air B200

Date 1/27/2011

Satnan Avionics completed their first dual installation of the Garmin G600 flight display in one of the local hospital’s air ambulance.  The installation completely removed all of the Collins Pro Line 2 equipment with the exception of the autopilot.  The installation was slated for 3 weeks and was completed in that 3 week period with no problems.  This modification gives capabilities of WAAS, Synthetic Vision, Jeppesen Chart View, Traffic and the reliability of AHRS.  The WAAS capability this installation offers is the ability to complete approaches into airports that previously this company was not able to when the weather was down, which makes the G600 a fantastic tool for their Air Ambulance.

Update on FCC ELT Rulemaking

DATE: 07/20/2010

This is an update to the June 21, 2010, AEA Regulatory Update: FCC Bans
121.5 MHz ELTs

On July 8, 2010, the FAA sent a letter to the FCC requesting the proposed
changes to 47 CFR 87.195 prohibiting “the manufacturing, importation, sale or use of 121.5 MHz emergency locator transmitters (ELTs)” be rescinded, citing the detrimental effect to the aviation community.

The AEA supports the FAA’s proposal for operators to continue the “use of
existing” 121.5 MHz ELTs. However, because satellite monitoring has ceased for 121.5 MHz, the AEA does not support the FAA’s position of allowing the continued manufacture, importation or sale of new 121.5 MHz ELTs.

With the termination of the satellite monitoring of the 121.5 MHz ELT signals, the transmitter no longer meets its intended design function. The AEA is disappointed the FAA would make the unsupported and illogical argument that the proposed FCC prohibition on the further manufacturing, importation, sale or use of an outdated ELT transmitters is somehow detrimental to aviation safety.
