4. Title : SARAS Automatic Flight control system

Client : Center for Civil Aircraft Design &

Development (C-CADD)

Duration : Jan 2008 - Jan 2010.

Team Size : 5

Role : Team Member

RTOS : DEOS (Digital Engine Operating

System)

Compiler : Cygwin

Languages : C

Tools : DESK IT (DEOS Integration

Tool), TATS, DFTS

Configuration Tool : PVCS

Interface : CAN

Description : The Automatic Flight Control System (AFCS) for

SARAS aircraft is the Limited Authority Autopilot System which

provides following functional capabilities.

. Provide autopilot for three axis control.

. Provide flight director to provide the guidance up to Cat II

precision approach phase

. Provide steering commands to the pilot and co-pilot for

display on the EFIS in the FD mode.

. Crew Interface via Autopilot Control and Mode Select Panel

(ACMSP)

. Interface to other avionic systems

. Fault detection and Built-in Tests.

Contribution:

i) Design and development of flight phase calculation. This

includes writing

requirements after discussing with the

customers, design and development of flight phase

calculation. There are different flight phases

such as Parking, Taxi-in, Taxi-out, TakeOffRoll,

TakeOff, Climb, Cruise, Descent, Landing and

Landing Roll. All these flight phases are calculated

based on the following parameters Landing Gear

Down or Up, Calibrated Airspeed, Radio

Altitude, Change in Pressure Altitude, Pitch

Angle, Weight On Wheels and Ground Speed.

ii) SARAS Auto Flight Control System uses ARINC 429 data bus to

collect different information from different sensors and other

Avionics systems. Similarly Auto Flight Control System also

communicates with the sensors and the other systems via ARINC

429 data bus. ARINC 429 employs unidirectional transmission of

32 bit words over two wire twisted pairs using bipolar RZ

format. The commonly used word formats are BNR, BCD and Discrete

data for different Avionics systems and the sensors. Bits 31 and

30 of the ARINC 429 word format contain the Sign/Status Matrix

or SSM. This field contains hardware equipment condition,

operational mode, or validity of data content. The SSM values

for the different format has different meanings. For example,

00 in BCD format means Plus, North, East, Right, To, Above

and 00 in Binary format means Failure warning. So, the Auto

Flight Control System designed and developed to calculate the

SSM for different systems based the AFCS mode and state.

iii) As part of SARAS AFCS integration team, involved in defining and

configuring the inter process communication parameters between

and among the process. Each and every process in the AFCS system

will produce and consume certain parameters to\from other

process for their functionality to perform. So, the integration

team will define and configure the producer and consumer for the

given parameter. Also, the responsibility is to look at the rate

in which the parameters are produced by the producer and also

the rate at which the consumer are consuming the parameters. The

software design should be such that, the consumer do not consume

the items at higher rate compared to the rate at which the items

are produced.

5. Title : Quick Load Protocol

Client : Airbus A380

Duration : Feb 2005 - Jan 2008

Role : Team member and Module Owner

Languages : C & Assembly language

Hardware Platform : Motorola MPC256 (Micro controller),

MPC8250 (Power PC)

Compiler : Cygwin, Cosmic

Tools : BDM, Vision ICE Emulator

(Wind River), Status Monitor, Hyper

Terminal,

DESK IT

RTOS : DEOS

Interface : CAN, RS485, I2C

Configuration Tool : PVCS, Clear case

Description : SPDS (Secondary Power Distribution System)

is part of the Electrical Power Distribution System in the Aircraft.

These systems used wired networks e.g. RS485 for the purpose of

Dataloading on different LRMs in a LRU. The SEPDS have 2 SEPDC

(Secondary Electric Power Distribution Center) and 8 SPDB (Secondary

Electric Power Distribution Box).

The On-board Maintenance System (OMS) called Data Loading

Configuration System (DLCS) is used to initiate the downloading of

the Configuration Data File (CDF) and field loadable software for

each of the SEPDCs and SPDBs via the RS485. The SEPDC has 40 AC

LRMs, 3 GFI LRMs and 2 Gateway. The SPDB has 20 DC LRMs, 1 GFI LRM

and 2 Gateway. The operational software for Gateway1, Gateway 2, GFI

and AC modules are different. So, some protocol is needed to load

the operational software and the Configuration Data File via RS485

by communicating with the Generic Bootloader. This data loading

protocol should not take more than 20 minutes.

To accommodate the customer requirements, the Quick load protocol is

defined to load the Operational Functional Software (OFS) and the

Configuration Data File (CDF) on different LRMs via RS485.

Contribution:

i) Design and develop the Quickload protocol in the PowerPC

MPC8250 on DEOS Real Time Operating System. Quickload is a

separate process in the DEOS, receives Go A Head signal from

other process to start the data loading process through inter

process communication. The IPC used here is the Shared Memory

Object (SMO). Once the Quickload process completes the data

loading process it communicates the status to the other process

through IPC Shared Memory Object.

ii) Design and develop the Quick load protocol in the MPC256

microcontroller Generic Bootloader. The Generic Bootloader is

common across different types of Lrms GFI, GMCCOS and AC\DC.

So, the Quick load process from MPC8250 will send the

Operational Functional Software via RS 485 to the Generic

bootloader of different lrms. The operational Functional

software is different for different types of lrms. The

Bootloader will erase the flash, write the Operational

Functional Software data sent by Quickload process via RS485

and activate the Operational Functional Software.

iii) The Generic Bootloader will take the backup of the old version

of Operational Functional Software and flash the new version of

Operational Functional Software. In case, because of any

reasons, if the data loading fails to load the new version of

the software, then the Generic Boot loader will retrieve the

old version of the software from its back up. If the Data

loading is successful, then the Generic Bootloader will erase

the backup copy of the old Operational Functional software.

iv) To protect the Generic Bootloader from flash corruption of any

means, the Generic Bootloader enables the hardware flash lock.

So that, no one can erase the Boot loaders flash memory.

v) Also the Quickload process from MPC8250 communicates with the

external memory through I2C.

vi) Requirements, Design and Development of Generic Bootloader and

Quickload Process, integration with other modules and

functional testing.

vii) Quickload process will be active only in the download mode.

viii) Involved in debugging the software using BDM, Status monitor,

Video Stream and Vision ICE.

ix) Involved in Hardware and Software Integration testing

x) Involved in SEPDS product certification activities with JAA.

xi) Involved in updating and reviewing the certification artifacts

SVCP, SVP, SVR and SAS.
