Secondary Crash-Phone Circuit
The secondary crash-phone circuit can be activated from the control tower or from the
flight planning desk. This system is utilized for the simultaneous notification of essential
support and administrative personnel. As a guide, the following connected stations are
Structural fire organization
Hospital or dispensary
Aircraft maintenance department
Explosive ordnance disposal (EOD) personnel
Aircraft rescue boat house (if applicable)
Air Operations office that, in turn, will notify by regular phone or other means, the
Aviation Safety Officer and the senior member of the aircraft mishap board
Station Duty Officer who will notify by regular telephone those personnel
previously designated by the Commanding Officer
This system allows the flight planning dispatcher to notify all essential personnel and
activities, simultaneously without further interfering with control tower operations.
Crash-Phone Circuit Testing
The crash-phone is tested daily at all facilities to make sure it operates satisfactorily.
This test usually originates at the control tower on the primary crash-phone circuit and is
followed by a test of the secondary crash-phone circuit by flight planning.
Emergency Radio Communication Systems
Two radio networks coordinate crash and fire-fighting activities. The primary network is
referred to as the crash network (or crash net). The crash network provides
communications between the control tower and necessary mobile units such as crash
trucks and ambulances. The other network is used as a standby or spare in case of an
outage of the primary network. This secondary network is sometimes referred to as the
internal security network.
