SYSTEM DESCRIPTION AND INSTALLATION MANUAL

JetWave™ System

(3) The JetWave™ system incorporates three fail-safe features to limit the potential for human

exposure to non-ionizing radiation:

(a) The system will not transmit unless the receiver is receiving a va

lid signal, therefore if

the received signal were to become blocked the transmitter would be disabled.

(b) The antenna subsystem includes a hardware end

-stop that prevents the antenna from

pointing more than 2° below its mounting plane.

ed 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.

4.10 Inspection of Waveguide

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 antenna 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.

4.11 Cabling and Drawings

Refer to Table 4-10 for the cabling requirements.
