FTTI stands for Fault Tree and Trip Interlock. They are used to prevent or mitigate hazardous events in a system.

• FTTI is a safety mechanism used in complex systems to prevent or mitigate hazardous events.

• It involves creating a fault tree that identifies potential failure modes and their causes.

• The trip interlock is a safety feature that is activated when a fault is detected, preventing the system from operating.

• FTTI is commonly used in industries such as aerospace, automotive...read more

FTTI (Fault Tolerant Time Interval) is calculated to determine the time interval within which a system must detect a fault and take appropriate action to prevent hazardous events.

• FTTI is calculated by analyzing the time it takes for a fault to occur, be detected, and for the system to respond to prevent harm.

• It is crucial for ensuring that safety-critical systems can respond to faults within a specified time frame.

• For example, in automotive safety systems, FTTI calculations a...read more
