(3) Examine, along with technically qualified maintenance
personnel, the condition of the equipment to determine whether it
could have contributed to the accident or incident.
2.
RADAR EQUIPMENT
When radar equipment is or is suspected to have been involved in
an accident or incident, the facility shall discontinue providing
radar service until a flight check is performed.
During instrument
flight rule (IFR) conditions when aircraft cannot land using other
NAVAIDs or proceed to an alternate landing area, radar service shall
NOT be terminated if the pilot has been informed about the radar
equipment and concurs in its use.
3.
RADIOS
a. ATC facilities are authorized to join radio nets with the
crash and rescue team, airfield services, weather station, fire
station, ambulance service, and security agency.
To the extent
possible, these radios will terminate within the communications
console.
b. During operating hours, ATC facilities shall continuously
monitor all assigned radio frequencies. Facilities that share radios
shall establish procedures to ensure that assigned frequencies are
continuously monitored by one of the facilities.
c. All ATC facilities should have a transmit-receive capability
on emergency frequencies 121.5 megahertz (MHz) and 234.0 MHz.
When
ATC facilities are close, transmitters and receivers shall be shared
between the facilities if no degradation of services will result. If
transmitters and receivers are shared, geographical area coverage
shall NOT be derogated and transmitters will be equipped with lockout
devices to avoid inadvertent interference between facilities.
d. The two emergency channels shall NOT be terminated on the same
transmit-receive key selector of any other frequency. Where a remote
communications console is provided to a non-ATC facility at an
airfield that has as an ATC facility, only the emergency receiver
shall be provided.
ATC facilities without an emergency frequency
capability shall have appropriate telephone lines for relaying
emergency information.
4.
CRASH ALARM SYSTEM
a. AR 385-95 prescribes policies, procedures, and guidelines
regarding the primary crash alarm system, the secondary crash alarm
circuit, and local crash grid maps.
However, crash telephone and
radio receiver or transmitter keys should be centrally located so
they are readily available to all control positions.
