T-45C TS, ADV & IUT ENG-27/ENG-28
Engineering Review
NOTE: Because of the redundant design
of the COMM system, the possibility of a
total COMM failure is minimal.
(2) Verifications
(a) Check Communications transfer switch
settings
(b) Check COMM control panel switch
settings
(c) Check UHF/VHF radio control panel
switch settings
(d) Check helmet/mask connections
(e) Verify other cockpit experiences same
problem
(f)
Still receiving navigation audio
(g) Check with other aircraft
(h) Perform BIT
NOTE: If a malfunctioning UHF/VHF
radio control panel is causing the
problem, communications can be
transferred to the other cockpit, if
occupied. If a faulty receiver/
transmitter is causing the problem,
select the other COMM system. If both
COMM amplifiers have failed, the
communication system is lost.
(3) Effects on flight safety: normal air-to-air
and air-to-ground communications will be
lost
Examples of hazards:
*
Lost comm procedures will apply
*
Possible traffic conflict
