Figure 3.5.1-6 FDQ Fore-Aft Tilt
The FDQ must be mounted with fore-aft tilt within +/-1 degree of longitudinal level, using
the aircraft water line as reference.
Figure 3.5.1-7 HPB Fore-Aft Tilt
The HPB antenna may be mounted with a fore-aft up-tilt angle of up to 10 degrees,
using the aircraft water line as reference.
Figure 3.5.1-8 HPB and FDQ Antenna Separation
In situations where antennas are shadowed from each other by the aircraft fuselage a
reduced separation of no less than 120” edge to edge is permissible as shown in Figure
3.5.1-8.
The edge-to-edge separation of the antennas must be greater than 168 inches in same
antenna plane installation, meaning when positioned fore and aft along a flat fuselage
surface. Please consult with WSS in each situation to ensure performance degradation
risk is assessed.
