Frequently Asked Questions
Is Glendale Airport radio encrypted?
Yes — Glendale Airport's radio system runs on P25 AES-256 encryption. All traffic, including the day-to-day dispatch that used to be the public's window into police activity, now runs encrypted. Nothing from this department is receivable.
Can I listen to Glendale Airport on a police scanner?
No. Glendale Airport has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Glendale Airport encrypt their radio?
Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Maricopa County where an open channel caused harm. The costs need no such documentation: reporting on airport authority response slows down, and mutual-aid coordination gets more awkward, immediately.
Can Maricopa County reverse the encryption decision?
Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.
What can I do about Glendale Airport encryption?
Start local: show up when Maricopa County officials discuss the budget for Glendale Airport, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
