1Introductory Information
These Instructions for Continued Airworthiness (ICA) provides instructions necessary for
authorized personnel to inspect and maintain the EFD500 and EFD1000 system installed by the
EFD1000 AML-STC.
This document must be printed and included with the aircraft Instructions for Continued
Airworthiness, and arranged for easy and practical use.
Description of the Appliances and its Systems and Installations:
The Aspen Avionics EFD1000 and EFD500 systems are multi-purpose displays. The EFD1000
contains an internal Air Data and Heading Reference System (ADAHRS) that is used to provide
attitude, heading and air data for the display. The EFD500 is a variant of the EFD1000 and does
not contain the internal ADAHRS. The EFD1000 (except the Evolution Backup Display (EBD)
version) and the EFD500 come standard with an internal battery to provide a nominal 30 minute
operation in the event of power loss. These batteries (except for the EFD1000 E5) are not
designed to provide 30 minute operation under all foreseeable operating conditions, such as
extreme cold temperatures where battery operation is not assured. The EFD1000 E5 internal
battery does provide at least 30 minutes of operation under all foreseeable operating conditions.
An optional (standard on EBD) Emergency Backup Battery (EBB) is available that will provide at
least 30 minutes of operation under all foreseeable operating conditions. Typical EBB endurance
at 25 deg C will exceed two hours when the battery is fully charged. When an Aspen Primary
Flight Display (PFD) is installed, and the Emergency Backup Battery is connected to an EFD1000
Multi-Function Display (MFD), the legacy standby altimeter and airspeed indicators may be
removed from the aircraft. When the EFD1000 EBD is installed as backup instruments to non-
Aspen PFD, the legacy standby altimeter, airspeed and attitude indicators may be removed.
Additional equipment is normally installed in support of the displays, including the Remote
Sensor Module (RSM), Configuration Module (CM), optional Emergency Backup Battery (as noted
above) and optional Analog Converter Unit (ACU). Several external sensors can optionally be
connected to the displays, including GPS systems, datalink weather receivers, the Aspen CG100
Gateway, WX-500 Stormscope, GTX330 and certain other ARINC 735A protocol TAS and TCAS I
systems. The Avionik Straubing APS4A Altitude Preselect System can be installed for Altitude
Preselect capability. The EFD1000 E5 has required connections to an RSM, CM, and one GPS
receiver and optional connections to an ACU and one navigation receiver.
The EFD1000 system can be configured as a PFD or MFD or EBD or E5. In the PFD, EBD, or E5
configuration, the EFD1000 provides display of attitude, airspeed, altitude, direction of flight,
vertical speed, turn rate, and turn quality. The system can provide display of navigation
information, pilot-selectable indices (“bugs”), and annunciations to increase situational
awareness and enhance flight safety.
The “Pro” and “Pilot” configuration are available in software version 2.1 and later. The EBD
“Advanced” and “Basic” configuration are available in software 2.8.3 and later. The E5 is available
in software E5 2.10 and later. The EFD1000/500 MAX displays are available in software 2.10 and

later. The Pro and EBD “Advanced” System can display WX-500 data, datalink weather products
and traffic information from ARINC 735 compatible traffic systems. The Pilot and EBD Basic
systems provide a moving map; however they do not provide an HSI or second GPS navigation.
The E5 does not have a moving map but can display information from one GPS and one
navigation receiver.
The EFD1000 can also be purchased in a multi-function display configuration with reversion
capability to a Primary Flight Display. The EFD500 is a variant of the EFD family that does not
include an ADAHRS. The EFD500 may only be purchased in a multi-function display
configuration, and does not include reversion capability. The E5 is standalone with no second
display option.

It may be required to align the EA100 Adapter to the autopilot computer using
a KTS-150 Test Set, a KTS-158 Test Set, a KTS-154 Test Set or equivalent and
following the autopilot manufacturer’s procedure for aligning the gyro (KI-
256) to the autopilot computer (these Test Sets are normally available at
autopilot-qualified Bendix-King dealers). The EA100 Alignment Tool
(acquired through the dealer ramp Section of the Aspen.com web site, see
Tech Note 2010-10) will be used to manipulate the gyro pitch and roll signals
and the autopilot Test Set will be used to measure the autopilot demodulated
gyro voltages. In the case of the KFC225 the Remote Terminal Interface
(normally available at autopilot-qualified Bendix-King dealers) will be required
in place of the test sets.

2System Description and Information about the Interface of the
EFD1000/500 System with the Aircraft
The EFD1000 PFD, EFD1000 EBD, and EFD1000 E5 system is comprised of the Electronic Flight
Display (EFD), Remote Sensor Module (RSM), Configuration Module (CM) and optional Analog
Converter Unit (ACU or ACU2). Optionally one or two MFD displays of either the EFD500 or
EFD1000 may be installed with an accompanied PFD system. An optional EA100 Adapter
(autopilot attitude adapter) may be installed.
The EFD1000 PFD, EBD and E5 system provides display of attitude, airspeed, altitude, direction of
flight, vertical speed, turn rate, and turn quality. The system may optionally provide display of
navigation information through interfaces to GPS Receivers and/or VHF Navigation Receivers.
When interfaced with a compatible autopilot, the EFD1000 system provides heading and course
datum information to the autopilot, which enables the autopilot to follow the Course and
Heading values set by the pilot on the EFD1000.
If optional MFD displays are installed they can present terrain, traffic, weather, and WX-500
Stormscope data to the flight crew. The EFD1000 MFD can be used as backup instruments to the
PFD supporting reversionary capabilities. The EFD500 presents MFD data, but cannot be used for
backup or reversion.
The optional EA100 supplies pitch and roll stabilization signals to the autopilot. The article has
no direct pilot controls.
The Avionik Straubing TSO’d APS4A is integrated with the EFD1000 and provides Altitude
Preselect capability. The APS4A is not applicable to the EFD1000 E5.
The CG100 Gateway allows mobile devices to interface to other avionics through an EFD1000
MFD or EFD500 MFD.
NOTE: Other modifications to the aircraft could affect the EFD1000 PFD and MFD magnetic
sensors. The EFD1000 PFD and MFD heading performance should be checked after other
modifications. See Section 10.5.4, heading accuracy test in the EFD1000 and 500 SW 2.X
Installation Manual, document 900-00003-001 revision BY or later.

3Description of How the EFD1000 System Operates and is Controlled,
Including Special Procedures and Limitations
The EFD1000 system is controlled by a switch marked “EFD1000 PFD” or “PFD”, “ASPEN” (for EBD
system), “EFD” (for E5 system) and, (if installed) “EFD1000 MFD”. The system is ready to be
operated when the initialization screen disappears, and the EFD1000 attitude and heading
display is shown. See the EFD1000 Aircraft Flight Manual Supplement (AFMS), document 900-
00008-001 or EFD1000 E5 Aircraft Flight Manual Supplement (AFMS), document 900-00038-001
regarding which appliances are installed, how the EFD1000 system operates, and is controlled,
and special procedures and limitations.
An EBB58 Emergency Backup Battery is required for EBD installations and may be required in
some EFD1000 MFD installation configurations if it is being used as any required secondary
instruments.
See the attachment to this document (part of permanent aircraft records) for detailed interface
information.
3.1 Maintaining Security Safeguards With the Aspen Connected Panel
The Aspen Connected Gateway is an appliance not required by 14 CFR Part 23 that permits bi-
directional communication of data between wireless devices and the EFD1000 MFD. Security of
the communication link to the EFD1000 MFD is important and appropriate for these instructions.
Generally, the system automatically controls the security aspects of the communication link,
however the operator has responsibility to assure adequate security when it comes to the human
interaction.
3.1.1 Physical Security
The Connected Gateway System can be linked to several wireless devices at the same time. Only
devices that are within range of the Wi-Fi signal can be linked. Therefore the devices that can be
linked while in flight are limited to the devices in the aircraft. Physical security does not require
maintenance or assurance for continued airworthiness. This is an operator consideration.
3.1.2 Operational Security
When the aircraft is in operation, only those systems used for Connected Gateway should be
linked. Keep the password confidential. The operator should assure that only authorized devices
have access to the Connected Gateway. Operational security does not require maintenance or
assurance for continued airworthiness. This is an operator consideration. The password for the
Connected Gateway Wi-Fi for a particular aircraft should be safeguarded and only supplied to
those who are trusted. If an unexpected device is connected and a flight plan is sent, the choice
is simply to reject the flight plan.

3.1.3 Security Safeguards Monitoring
If there are attempts to violate security rules while in flight, as shown by an unexpected
candidate flight plan, reject the flight plan and turn off Aspen GTWY by the switch. Do not
operate it until the security breach is addressed.Security safeguards monitoring does not
require maintenance or assurance for continued airworthiness. This is an operator consideration.
3.1.4 Management Procedures
Measures should be established to prevent malicious introduction of unauthorized modifications
to the wireless device, including the operating system, the hosted applications and the databases
or data links. This might include maintaining a separate wireless device that is exclusively for
aircraft use and limiting the number of applications loaded to those that are known to be non-
malicious. Management procedures do not require maintenance or assurance for continued
airworthiness. This is an operator consideration.
3.1.5 Maintenance Procedures for Maintaining Security Safeguards
With the EFD1000 or EFD500 MFD and the CG100 operating, display the CG100 status by going
to the MFD Gateway page. Verify that Device: LINK STATUS CG100: is reported as LINKED. Use a
wireless enabled device to search for the SSID of the installed Gateway. By default, the SSID is
ASPENCG100. Verify that access requires a password. This also checks the functionality of the
CG100 Gateway software and hardware.
4System Operation and Procedures for System Testing During Ground
Running
Refer to the EFD1000 AFMS, document 900-00008-001 or EFD1000 E5 AFMS, document 900-
00038-001 for instructions on system operation. For System Testing refer to Section 10,
Appendix E (EA100), Appendix F (A/P Source Select), Appendix G (APS4A) and Appendix H
(CG100) of the EFD1000 and EFD500 SW v2.X Installation Manual, 900-00003-001 Rev BY or
later. For the EFD1000 E5 refer to Section 10 and Appendix E (EA100) of the EFD1000 E5 Dual
Electronic Flight Instrument (EFI) Install Manual, 900-00041-001 Rev ( ) or later.
NOTE: Appendix H of document 900-00008-001 directs the user to another supporting
document (900-000023-001, see “System Checkout”) information for the CG100. This is
because the primary document for the STC is document 900-00003-001, and information
regarding support documentation will be in this document.
To check the functionality of the CG100 Gateway software and hardware, see Section 3.1.5.
