What is a possible time frame for flashover to occur on an airplane?

Flashover in an airplane can occur within 90 seconds due to the rapid spread of fire and the accumulation of heat in a confined space. This quick time frame is influenced by the materials used in aircraft construction and the presence of flammable fluids and vapors that can ignite easily. In emergency situations, where various systems can be compromised, conditions can easily worsen, leading to a near-instantaneous escalation of fire intensity. Understanding this time frame is critical for crew members to effectively manage emergencies and ensure passenger safety during an in-flight incident.
