Figure G-6 Zoning For A Single Propeller (Low- Or High-Wing - Garmin GI 275 Installation Manual

G.2.2 Fuselage
This section describes the zoning for several different types of fuselages. The empennage is zoned in
Appendix Section G.2.3. Aft of every Zone 2A is a 0.15 meter Zone 2B (i.e., Zone 2A is followed by a
0.15 meter Zone 2B). Although Zone 2B areas are marked on the diagrams, sometimes their widths are not
defined (0.15 meters should be used in these cases). The horizontal stabilizer of the tail is not zoned
because neither the GTP 59 nor the GMU 11/44B can be mounted there. In addition, neither the GTP 59
nor the GMU 11/44B can be mounted within 0.5 meters of the rear-most point of the fuselage. Appendix
Section G.2.3 explains the conditions under which the GTP 59 or GMU 11/44B can be mounted on the
vertical stabilizer. Although all diagrams show low-wing aircraft, the same zoning can be applied to high-
wing aircraft. The values d

G.2.2.1 Single-Propeller Aircraft
Zoning of low- or high-wing aircraft with single propellers is shown in Figure G-6. The area of the nose
immediately aft of the propeller is Zone 3. The 0.6-meter distance should be measured from the outboard-
most edge of the fuselage or the tip of the propeller, whichever is longer. Figure G-8 shows the case of an
aircraft with a curved fuselage. The portion of the fuselage that extends 1.3 meters aft of the propeller
blades is Zone 1C. However, the bottom centerline is Zone 2A, and it is acceptable to mount the GTP 59
there.
