altitude-terminated way-point

For flights in areas where a transition altitude is established, the vertical position of the aircraft shall, except as provided for in (5) below, be expressed in terms of altitudes at or below the transition altitude and in terms of flight levels at or above the transition level.

Suborbital flights could constitute a promising market for: (i) scientific experiments: microgravity experiments, astronauts training, test of satellite payloads, (ii) space tourism and (iii) future clean, high altitude, high speed and point-to-point air transport systems.

‘altitude’ means the vertical distance of a level, a point or an object considered as a point, measured from mean sea level (MSL).

a surface abutting the end of the strip associated with runway approach 36 consisting of an inclined plane having a ratio of one (1) metre measured vertically to twenty (20) metres measured horizontally rising to an intersection with the outer surface, thence said approach surface shall be contiguous to said outer surface to an intersection with the southern extremity of said outer surface, said intersection being on the projected centre line of the strip and distant three thousand eight hundred and fifty (3 850) metres from the end of the strip, the outer end of said approach surface shall be an imaginary horizontal line drawn at right angles to the projected centre line of the strip, the outer ends of the imaginary horizontal line being s ...[+++]even hundred and twenty-seven decimal five (727.5) metres from the projected centre line, said imaginary horizontal line being forty-five (45) metres above the airport reference point;
