Which is a consequence of using dry powder fire extinguishers inside an aircraft?

Using dry powder fire extinguishers inside an aircraft does indeed leave a corrosive residue that must be cleaned up after use. The dry powder is effective for various types of fires, including those involving flammable liquids and gases, but it has a downside. This powder can be detrimental to the sensitive onboard equipment if not properly cleaned up after use, as it can cause corrosion or damage to electronic components and other surfaces due to its chemical properties. Therefore, the requirement to remove this residue is a significant consequence of using dry powder extinguishers in the confined environment of an aircraft.

Other options may discuss aspects like weight or ease of handling, but they do not address the critical issue of residue management, which is particularly important in aviation safety and maintenance.
