FSX Is it possible to disable (damage) the GPS?

I have not built a mission since 2007 :O and began with a new one now. I am reading the SDK for missions but am still wondering, is it possible to have the built-in GPS *disabled* or even better "damage" it during the course of the mission.

The purpose being to prevent the "missionary" to use the GPS for orientation and limit it only to the mission compass without any other reference. Is that possible?
