JetWave™ MCS-8562 Terminal
The system will not transmit unless the receiver is receiving a valid signal, therefore
if the received signal were to become blocked the transmitter would be disabled.
The antenna subsystem includes a hardware end-stop that prevents the antenna
from pointing more than 2° below its mounting plane.
An input into the JetWave™ MCS-8562 Terminal wired on the aircraft to a switch
in the aircraft, to disable the RF transmission. This switch would be used to prevent
any radiation from the antenna in the event of aircraft operations in the vicinity of
the antenna, for instance when de-icing the aircraft. This would be achieved by a
defined procedure on the aircraft.
Any waveguide received that contains more than one dent is unacceptable and
must be returned to the vendor. Dents must not exhibit obvious signs of mechanical
rework such as file marks or rough edges, where it is obvious that small tools have
damaged what should be a precisely machined waveguide.
The very outer edge of the waveguide does not generally contain critical portions
of the waveguide structure that affect performance. Therefore the outer edge of
the waveguide may include small dents, marks, machine tool marks, etc so long
as the damage does not structurally impair the waveguide. The outer surface may
contain bending, tool marks or handling damage. A new waveguide that contains
large numbers of dents or marks such that it appears not to be a new article shall
be rejected and returned to the vendor. If more than 25% of the waveguide surface
is marred in any way , the component must be rejected and returned to the vendor
for rework.
Any evidence of nicks, surface pits, surface etching or scratches on the waveguide
are acceptable as long as the flaw has been caused by the manufacturing process,
i.e. brazing, cleaning, honing, a tool and no larger than 0.030 inch etc. The number
or shape of the nicks, pits or scratches are not limited unless greater than 25% of
the waveguide appears to have sustained overall damage of one or more types.
Any waveguide having more than 25% of the surface damaged in this way is not
acceptable and must be returned to the vendor.
The surface finish of the waveguide must not exceed 125 micro inch finish. All
measurements will be made in an area free of braze material. The surface finish
will not pertain to any area where excess braze material has flowed on the back
of the waveguide.
