(e) The surface gradient of the LZ should not exceed 2 percent.

(5) Approach and takeoff clearance. The approach and takeoff clearances are baaed on the glide-climb characteristics of the aircraft For medium aircraft the glide-climb radon is 1 to 40; that la, I foot of gala or loae of altitude for every 40 feet of horizontal distance traveled. The ration for light aircraft Is I to 20. as a further precaution┬╗ any obstructions in approach and departure lanes must conform to the following specificatlona (Figure 14).

(a) Aa obstruction higher than 6 feet (2 meters) Is not parnlasible at or near either end of the i.Z.

(b) A -foot (16 meters) obstruction may not be nearer than 2,000 feet (610 meters) for ^medium aircraft, or 1,000 feet (306 meters) for light aircraft.

(o) A 600-foot (165 meter) obstruction may sot be nearer than 4 miles (617 kilometers) for medium aircraft or 2 milee {M6 meters) for light aircraft.

(d) Kills of 1,000 (SO S meters) feet or more above L2 altitude may not be nearer thaatmllss (19 kilometers) from the landtag acne for medium aircraft.
