Q

What are the characteristics of FLS?

A
  1. Own part number
  2. May be an aircraft part
  3. The part number is verifiable on the aircraft by electronically accessing the target hardware memory.
  4. FLS does not change the target hardware’s P/N
  5. FLS can be uploaded regardless of the current software state and it will NOT prevent a previous version from over writing it.

Q

User CERTIFIABLE software (UCS)

A

Software an operator or its designated party chooses to modify, a change to UCS requires CERTIFICATION.

17
Q

Define Operational Program Software (OPS)

A

Software that contains the program instructions for a LRU, each version has a unique PN.

18
Q

Define Operational Program Configuration (OPC)

A

Eliminates requirement for pin programming of LRU. Determines function of LRU.

19
Q

Define Aircraft Config List (ACL)

A

List of modules and LRU’s that use LSAP’s.

20
Q

Where are the Aircraft config lists found?

A

1.Drawing by type cert
2. Service bulletins
3. Service info letters
4. IPC

21
Q

What is software media?

A

Means of transporting software ie: floppy disc. CD, memory cards etc.

22
Q

How is software version laid out?

A

A.BB
A = Major version
BB = minor Version

23
Q

What methods are used to load data to the aircraft?

A
  1. Airborne data loaders
  2. Portable data loaders
  3. Portable maintenance access terminal (PMAT)
24
Q

When loading software to aircraft what is the procedure?

A

Always follow the loading procedures as defined by the operator and the AMM.

25
Q

What needs to be recorded when FLS is loaded?

A
  1. Recorded in Aircraft Config List. ACL
  2. Copy kept onboard with aircraft and operators records
  3. If its an LSAP it must be issued with a CRS by licensed staff.
26
Q

Define Electronic distribution of software.

A

Manufacturer/operator will supply the aircraft the data via internet and satellites. a CONFIDENCE check is recommended to ensure satisfy their intended use.

27
Q

What is the process of replicating a FLS?

A
  1. Use approved FLS storage media replication process
  2. Recorded in replication register
  3. Copy of original CRS attached to replica.
28
Q

Changing software can be very dangerous and lead to catastrophic effects what are some of the systems this could effect?

A
  1. Engine systems
  2. Nav systems
  3. Flight control system.
