WHAT ARE THE LAW ENFORCEMENT AIR SUPPORT CALL-SIGNS
FOLLOWINGS AREN'T USUALLY COVERED
Why? This is because there are several followings each day. Normally, these followings do not yield pursuits. Once an Agency goes into Pursuit, however, coverage begins.
WHY DO PURSUITS GET TERMINATED OR CANCELLED?
Police Departments are increasingly adopting a policy of cancelling Pursuits to promote public safety. #Serve&Protect
So when does this happen? This occurs when the Suspect is driving recklessly, against traffic, when the Suspect has committed a minor offense, or if the Agency knows who the the suspect is.
Many times, Pursuits are often cancelled due to poor traffic or weather conditions.
AVIATION INFORMATION, SQUAWK CODES, AND ACRONYMS
Squawk Codes:
1200 VFR - Visual Flight Rules
1202 - Gliders
7500 - Hijack
7600 - Communications Failure (Radio Failure)
7700 - General Emergency
7777 - Military Intercept Code. DOD interceptor aircraft on active air defense missions and operating without ATC clearance
What Are Squawk or Transponder Codes?
Transponder Codes are four digit numbers transmitted by the transponder in an aircraft in response to secondary surveillance. This assists air traffic controllers in maintaining traffic separation.
A discrete Transponder Code (often called a Squawk Code) is assigned by air traffic controllers to uniquely identify a specific aircraft. This allows easy identification of aircraft on radar systems.
Common Aviation Acronyms:
VFR - Visual Flight Rules
IFR - Instrument Flight Rules
MSL - Median Sea Level
AGL - Above Ground Level
WX - Weather
LZ - Landing Zone
MOA - Military Operations Area
TFR - Temporary Flight Restriction (Commonly Used In Air Shows / Sports Events, Security Events, Hazards, Fires & VIP Situations
ATC - Air Traffic Control

FOD - Foreign Object or Debris
MAFFS - Modular Airborne Firefighting System - the USAF can load the tanks on the aircraft within hours and deploy to a fire if and when needed
Prohibited Areas - Prohibited areas contain airspace of defined dimensions within which the flight of aircraft is prohibited. A common misconception is that aircraft cannot fly over the Disneyland Resort TFR (above 3,000 feet in a 3 mile radius)
Restricted Areas - Restricted areas are areas where operations are hazardous to nonparticipating aircraft and contain airspace within which the flight of aircraft, while not wholly prohibited, is subject to restrictions

Patrol Stations
CALIFORNIA HIGHWAY PATROL
CHP Frequencies are named after colors, unlike LAPD or LASD Agencies, which use geographical dispatch frequencies.
For example, when you see or hear a Pursuit as being called "Pursuit on the Orange", Orange refers to the Baldwin Park Station.
When CHP is in Pursuit, they will hand the Pursuit off to the next station if it goes into another area or jurisdiction. If it starts in Baldwin Park (Orange), for example, and goes south, the Baldwin Park Units will pass it off and Santa Fe Springs (Gold) Units will take over the Pursuit.
