d. Mobile Objects Within the FATO and the Safety Area. The FATO and Safety Area design

recommendations of this AC are based on the assumption that the TLOFFATO is closed to other aircraft if a helicopter or other mobile object is within the FATO or the associated Safety Area.

e. FATOFATO Separation. If a heliport has

more than one FATO, the separation between the perimeters of the two FATO, should be such that the respective Safety Areas do not overlap. This separation is based on the assumption that simultaneous approach departure operations will not take place. NOTE: If simultaneous operations are planned, greater separation will be required. `

f. FATO Gradients. Recommended FATO

gradients are defined in Chapter 8. 203. SAFETY AREA. A Safety Area surrounds a FATO and should be cleared of all obstacles except small frangible objects that, because of their function, must be located there.

a. Safety Area Width. The minimum

recommended width of a Safety Area is dependent upon the heliport markings. The Safety Area width is dependent upon the use of the TLOF markings paragraph 209a, the FATO markings paragraph 209a, and the standard heliport identification marking i.e., the H, paragraph 209b1. The recommended size of the Safety Area in Table 2-1 is increased if the TLOF perimeter is not marked. The minimum recommended width of the Safety Area is the same on all sides. The Safety Area may extend into clear airspace.

b. A Precision Approach Safety Area Width for operations under Instrument Flight Rules

IFR. RESERVED.

c. Mobile Objects within the Safety Area.

See paragraph 202d.

d. Fixed Objects Within a Safety Area. No

fixed object should be permitted within a Safety Area except for frangibly mounted objects that, due to their function, must be located there. Those objects whose functions require them to be located within the Safety Area should not exceed a height of 8 inches 20 cm above the elevation of the FATO perimeter nor penetrate the approach departure surfaces or transitional surfaces. e. Safety Area Surface. The Safety Area need
