Airport Crash Fire Alarm System
Background

With modern airports, equipped with modern instrumentation, controlling planes that also have state-of-the-art equipment on board, air crashes are few and far between, despite the annual increase in air traffic.

But should a crash occur, the main question is - can the airport efficiently handle the plethora of problems associated with an aircraft crash, and minimise damage and loss of life and injury?

Important Considerations

There is very little warning  before a crash, consequently the fact that an aircraft has either crashed, or is about to crash, has to be communicated as rapidly as possible to all the parties who who normally be associated with providing a service, both in and around the crash site.   The staff associated with providing these services are often not in an office, consequently the fastest method of communication is by the use of mobile (cell) phones.   What is very important is to make sure that the service provider's staff have received the crash notification, and that they key in their state of readiness, so that standby staff can be called up if the main staff are not available.

The media also needs to be informed, so that they can contact the general public, and ask them to avoid the crash site area, in order to allow emergency services faster access to the crash victims.

Airport management needs to be informed, so that they can prepare to handle all the queries from people associate with the passengers

Due to the vast amount of traffic, the airports Joint Operations Control Centre will very likely be swamped with incoming callers, and will find it difficult to dispatch service providers efficiently.

Excess traffic will often block the Airport's PABX, making communication very difficult.

Heavy radio traffic will also occur as all the verious rescue teams start to operate.

Communications

All the above require communications, and many of the normally reliable communication channels at the airport are likely to be overloaded or blocked.

Consequently, the Micromation CFR System makes use of private wires (main and standby) between the various operators (ATC, FIre Control Centre, etc) at the airport, each pair constantly being checked for possible cable faults, and able to automatically divert to another cable if faults are found.  As these cannot be blocked, or accessed by the general public, when contantly monitored they become a very reliable communication channel.   Note that  there us no need to have manual daily or weekly checks, as the system automatically checks these circuits, and will report any failures.

Of course, private wire communications cannot be used for general communications.   Here Micromation utilises a powerful voice notification system to communication with service providers over various dial lines or channels.   The voice notification system has been shown to be able to communicate with a considerbale number of people far faster than operators in a control centre can, as those called cannot "discuss" the crash with a computer.

 Communication Interfaces

The Micromation CFR system  makes use of  private wires, dial lines or channels, or Primary Rate ISDN for all speech communications.

Data communications is done by means of the airports LAN or WAN

Controls, such as those used to automatically open the doors of the building housing the Fire & Rescue vehicles at the airport, as well as to power the airport's long range CFR siren are provided.
