Background
• Each helicopter has around 400 individually identifiable and traceable LRUs.
• Each LRU has an unique serial number based on :
– Standard of Preparation
– Flight hours carried out
– Inspection details
– Revision history
• LRUs pertain to the following systems –
– Display
– Navigation
– Communication
– Control – electronic & hydraulic
– Data capture

Present Methodology
• Presurvey activity involving removal of LRUs from
helicopter
• Manual check and noting down the LRU serial number
• Secure LRUs back in their location
• Manually update the log card
• Stockpile the log card

12
• Highly time consuming process
• Damages to LRU cables, gaskets, facet
• LRU refitment inconsistencies
• Manual written errors while updating log card
• Pile of paper storage
• Difficulty to trace log card from stockpile
• Difficulty to trace LRU at stores
Difficulties in Present
Methodology

13
Business Need
To put in place a robust tracking & monitoring system
which enables –
1. Physical stock taking & audit of LRUs onboard helicopter without
removing them from their locations
2. Inventory control
3. Configuration control
4. Life monitoring
5. Utilization monitoring
6. Track & trace at stores

14
Objective Simplified… How?
The answer is RFID.
Principle :
• RFID – a unique identification technology using radio waves.
• RFID Systems consist of a transponder, also known as a tag,
which is a microchip connected to an antenna.
• The tag is mounted to an asset, and a device called a reader
communicates with the tag via radio waves.
• Depending on the type of tag used, the reader can receive
data as simple as an identification number or even detailed
information.

RFID in Aviation Industry Facts
1. Boeing selected RFID to track around 2,000 missioncritical parts on
each of its 787 jetliners
2. Airbus A380 is outfitted with over 10,000 parts tagged with RFID
chips
3. Airbus is using passive RFID labels on passenger seats and life
vests in A380.
4. Airbus is looking to RFIDtag removable/critical parts like plane
brakes etc, which must be overhauled after every 1000 landings

1. RFID promises unattainable visibility and accuracy in tracking the
a. Recognition
b. Authenticity
c. History / Genealogy
d. Even performance of key components
2. Improve inventory accuracy
3. Increase visibility of parts/components
4. Improve and streamline maintenance functions
5. Reduce lost parts and time in locating lost parts
Business Benefits of RFID

19
Extended Business Value of
RFID for Helicopter Business
• Onboard helicopter – for LRU inventory & audit
• At Stores – for trace & inventory check
• At Units – for audit, trace & replenishment

20

• Equipment failures
• System failures
• # of landings
• Helicopter running hours
• Pilot reports
• Asset health status
• Snag details
• Rotables tracking

Challenges
1. RFID tag weight :
This is proportional to read range.
2. RFID tag shape in line with LRU shape :
Minimum standardization on tag shapes
a. A concentric circle design (for all LRUs in cockpit area)
b. A rectangle design (for all other remaining LRUs)

22
Summary
• RFID tag an integral part of LRU
• Does not hamper LRU handling
• LRU traceability ensured
• Total weight of tags less than 5kgs
• Passive gadget – no interference
• Conformity to Mil Std 810
• Operates on specific allotted frequency band
