The GDU lens is coated with a special anti-reflective coating that is very sensitive to skin oils,
waxes and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE ANTI-
REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and
an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.

1. INTRODUCTION
Content, Scope, Purpose
This document provides Instructions for Continued Airworthiness (ICA) for the NXi configuration
of the Garmin G1000 Integrated Flight Deck including the GFC700 Automatic Flight Control
System (AFCS) as installed in the Beechcraft King Air 300 Series, under STC SA01535WI-D.
This document satisfies the requirements for continued airworthiness as defined by 14 CFR
Part 23.1529 and Appendix G. Information in this document is required to maintain the
continued airworthiness of the G1000 and GFC700.
Throughout this document, the GFC 700 autopilot system is included in the G1000NXi system
description and is identified separately only when needed.
References to “300 Series” throughout this document include 300, 300C, B300, B300C,
B300GT, and B300CGT models. Items in this document that are aircraft model(s) specific will
identify the model(s) instead of “300 Series”.
References to “Beechcraft” throughout this document include other Manufacturer names
including Textron Aviation, Hawker Beechcraft, and Raytheon.
Applicability
This document applies to all King Air Model 300 Series aircraft equipped with the G1000NXi
system. All G1000NXi King Air 300 Series airplanes are configured per General Arrangement
drawing 005-00629-N2 Rev 1 or subsequent.
Modification of an aircraft by this Supplemental Type Certificate (STC) obligates the aircraft
operator to include the maintenance information provided by this document in the operator’s
Aircraft Maintenance Manual and the operator’s Aircraft Scheduled Maintenance Program.
Aircraft modified by this STC have been shown to qualify for operation in Reduced Vertical
Separation Minimum (RVSM) airspace as a group aircraft in accordance with Title 14 of the
Code of Federal Regulations (14 CFR) Part 91, Appendix G, “Operations in Reduced Vertical
Separation Minimum (RVSM) Airspace”, and Federal Aviation Administration (FAA) Document
No. 91-RVSM, Change 2 dated 2/10/2004, “Guidance Material On the Approval Of
Operators/Aircraft For RVSM Operations”. This qualification is based on analysis of the
configuration and performance of the air data, automatic altitude control, altitude alerting, and
altitude reporting systems. These systems must be maintained in accordance with the
inspections and tests specified in this document and other current maintenance practices to
guarantee continued compliance to RVSM specifications.
Identifying an STC Configuration
The General Arrangement drawing lists the G1000 System Software Version numbers approved
for this STC. This section shows where to find the installed software version and airframe type
in the G1000 system for service if the technician is unsure of what G1000 software and
configuration is installed.
1. Place the G1000 system in configuration mode (reference Section 3.1 for instructions).
2. On PFD1, go to the MANIFEST CONFIGURATION page in the SYSTEM page group.
In the SYSTEM field the G1000 system software part number and version number that
is installed is shown.
3. Next go to the GDU page group and turn to the AIRFRAME CONFIGURATION page.
The airframe series, engine, and prop types are listed in the AIRFRAME box.

2. SYSTEM DESCRIPTION
Equipment Descriptions
GFC 700 Operation
The GFC 700 is a fail-passive digital flight control system composed of multiple G1000 LRUs
and servos. The following functions are provided by the GFC 700 in this installation:
•Flight Director
•Autopilot
•Pitch Trim
•Yaw Damper
•Electronic Stability and Protection (optional)
Flight Director:
The Flight Directors operate within the GIA 63Ws and use data from the G1000 system,
including air, attitude and flight data, to calculate commands for display to the pilot and for the
Autopilot. Flight director command bars and mode annunciations are sent to the PFDs through
a high-speed Ethernet connection for display to the pilot and copilot. The flight directors
operate independently of the autopilot and allow the pilot to hand-fly the command bars, if
desired. The GMC 710 allows the pilot to switch the active director between flight director #1
(GIA1) and flight director #2 (GIA2).
Autopilot:
The autopilot operates within one high-speed GSA 80 servo (pitch trim), two GSA 80 servos
(pitch and roll), and one GSA9000 servo (yaw). Flight director data is processed within the
servos and turned into aircraft flight control surface commands. The autopilot cannot operate
unless the flight director is engaged.
Manual Electric Trim:
When the autopilot is not engaged, the pitch trim servo may be used to provide a Manual
Electric Pitch Trim (MEPT) function. This allows the pilot or co-pilot to adjust pitch trim from the
PITCH TRIM switch on the control wheel in lieu of using the elevator trim wheel. Trim speeds
are scheduled to provide easier control over a wide speed or configuration range. The PITCH
TRIM switch is split into two halves. The left half arms MEPT. The right half controls direction.
Both halves must be actuated at the same time to command the pitch trim servo to operate. If
only one half of the PITCH TRIM switch is actuated for more than 3 seconds, a red PTRM
message will appear on the PFDs.
Yaw Damper:
The yaw damper reduces Dutch roll tendencies and coordinates turns. It can operate
independently of the autopilot and may be used during normal hand-flight maneuvers.
Electronic Stability and Protection:
Electronic Stability and Protection (ESP) is an optional function that is intended to assist the
pilot in maintaining the airplane in a safe flight condition within the aircraft flight envelope. This
envelope is defined by pitch, roll, and airspeed. This feature is only active when in flight and the
autopilot is off.
