Which statement is true for software to be used for avionics?
It is core software, operational software and word processing software.
It is core software, operational software and graphic processing software.
It is core software, operational software and a database.
When can a change to the core software of a Line Replaceable Unit (LRU) be made?
When the SRM is available and states that changes to that LRU are permitted.
Only when authorisation of the aircraft manufacturer and the LRU manufacturer has been given.
By authority of the airline, but only when it guarantees an equivalent level of safety.
Which is usually effected by a database software change?
Parameter values only.
Programmes and parameters.
This is part of the control loop for the aircraft and should not be changed.
Which is a function of the operational software?
It defines the kind of display in the cockpit.
It interfaces one Line Replaceable Unit (LRU) to another.
It provides parameter values e.g. a/c weight.
Why should an aircraft's core software never be touched?
Because it is not part of the aircraft control loop.
Because it is part of the aircraft control loop.
Because it produces very high voltages.
Which system is affected by the implementation of new database software?
The kind of cockpit display is changed.
Only parameter values are changed.
