Narrative:

GPS jamming was being conducted. In accordance with fom (flight operations manual) a mandatory report is required in the event of 'GPS interference; jamming; or navigation disruption.' with the latest revision to the fom this report is now required to be entered in the aml (aircraft maintenance log). I inadvertently forgot to make an aml entry after I had made two other entries for maintenance related items. As there is nothing wrong with the aircraft GPS equipment when GPS jamming is being conducted; it is easy to forget to make an aml entry. I have previously brought attention to our flight safety department the fact that GPS interference testing is not being included in our NOTAMS. The notifications are available at faasafety.gov. There is additional interference testing going on throughout [this month]. I doubt these will be entered in our company NOTAMS. It is rather frustrating to see in our NOTAMS over two pages on latitude-longitude coordinates for cranes at phx but none for GPS interference testing which our company now requires an aml entry; a flight safety report; and a security report.a new requirement for an aml entry in the event of GPS jamming was inadvertently overlooked. Change the fom mandatory report table to read 'unknown' or 'unforecast' GPS interference; jamming; or navigation disruption and include FAA published GPS interference testing advisories in company NOTAMS. Not doing so leads to willful noncompliance with the fom.
