INTRODUCTION
This document fulfils the requirement called for in the
introduction to ATA 100, by providing a description of the
Penny & Giles Aerospace Ltd, Data Acquisition Flight Recorder
(DAFR) Type D51615-202-XXX or the DAFR fitted with the 90-
Day beacon kit Type D51615-202-XXX-090 in Part 1, Cockpit
Control Unit (CCU) Type D51616-XXXX in Part 2 and Cockpit
Area Microphone Type D51623-XXXX or Type D51702-XX in
Part 3. This document includes the installation and operating
procedures required supporting the unit in service.
The DAFR is used to record selected aircraft parameters,
including audio, into Solid State Non-volatile Memory. The
recording is protected to survive stipulated crash conditions, to
enable the subsequent retrieval and decoding by suitable
replay equipment following an incident.
Facilities exist within the DAFR for aircraft in-situ data
retrieval. The DAFR retains, as a minimum, both the most
recent 25 hours of aircraft data and the most recent 120
minutes of four audio sources.
The DAFR is configurable to support different user applications
through a configuration table upload. Different customer
configurations are identified by dash number suffix from the
main D51615-202 part number. Each variant fulfils the
requirements of the minimum CVR/FDR as identified by
EUROCAE document ED112.
The DAFR is designed to operate without a Flight Data
Acquisition Unit (FDAU) instead it acquires data through
integral acquisition circuitry and dedicated aircraft bus
interfaces. For aircraft in situ retrieval, suitable Portable Replay
Equipment (PRE) is required.
With the limitations set out in DDP 3050, the DAFR Type
D51615-202-XXX and DDP3076 meets the requirements of
European Organization for Civil Aviation Electronics (EUROCAE)
specification ED-112 Flight Data Recorder and Cockpit Voice
Recorder, European Aviation Safety Agency (EASA) and
Federal Aviation Administration (FAA) specifications ETSO-
C123a/TSO 123b and ETSO-C124a/TSO 124b.

DAFR Type D51615-202-XXX-090 meets the requirements of
EUROCAE specification ED-112 Flight Data Recorder and
Cockpit Voice EASA Specifications ETSO-C123b and ETSO-
C124b.
The Cockpit Control Unit Type D51616-XXXX may be used in
conjunction with each variant of the Penny & Giles Aerospace
Ltd Data Acquisition Flight Recorder and provides features
compatible with ARINC 757, Supplement 2.
The Cockpit Control Unit provides facilities to monitor and
display the operational status of the recorder and also contains
the preamplifier for the Cockpit Area Microphone. A jack socket
is available to monitor the summed audio output of the audio
recording system.
The Cockpit Control Unit is designed to function in accordance
with the requirements of ARINC 757 Supplement 2 and
EUROCAE documents ED-56A, Amendment 1 and ED-112.

Part 1: Data Acquisition Flight Recorder
1 DESCRIPTION, OPERATION AND SPECIFICATION
1.1 DESCRIPTION
1.1.1 General.
The DAFR Type D51615-202-XXX or D51615-202-XXX-090 is a
crash protected airborne recorder that is installed to meet
customer requirements. The DAFR meets or exceeds the
requirements of EUROCAE ED112, and satisfies the United
Kingdom Civil Aviation Authority (CAA) specifications 10, 10A,
11 and 18. The requirements of FAA TSO-C123b and TSO-
C124b are satisfied where regulations allow the fitting of a
combined voice and data recorder. The equipment is
compatible with interface requirements of ARINC 757
Supplement 2 for CVR functions. FDR data acquisition is
supported via three high or low speed ARINC 429 interfaces, 4
analogue inputs, 6 discrete inputs, a single rotor tachometer
input and an accelerometer input. DAFR Type D51615-202-
XXX is illustrated in Figure 1 and the Type D51615-202-XXX-
090 is illustrated in Figure 2.
The DAFR is mounted direct to the airframe. Anti-vibration
mounting is not required.
The DAFR consists of a solid state crash survivable memory
module and an electronic interface.
The solid state memory module is protected for crash
survivability. The electronic interface is not crash protected and
is not required to survive conditions exceeding the specified
operating and storage environment.
Facilities exist within the equipment to monitor all aspects of
operation for diagnostic purposes, reporting this information
through built in web pages accessible via commercially
available hardware and WindowsSoftware.
