| 1. | Foel Grochan mine consists of eight near-horizontal tunnels at approximately vertical separation.
|
| 2. | :See Flight level and Reduced Vertical Separation Minima for information on vertical separation.

| 3. | :See Flight level and Reduced Vertical Separation Minima for information on vertical separation.
|
| 4. | :Until 1999, the vertical separation between aircraft flying at high altitudes on the same airway was.
|
| 5. | If there is little or no vertical separation, vertical prism can be used to separate the lines.
|
| 6. | The points having the minimum vertical separation are also the tangency points for the maximally separated parallel tangents.
|
| 7. | "They had maintained a vertical separation throughout, " said H . S . Khola, the director-general of civil aviation.
|
| 8. | Larger solubility gradients should lead to more effective vertical separation while smaller gradients should lead to more homogeneous films.
|
| 9. | Since then there has been a phased introduction around the world of reduced vertical separation minimum ( RVSM ).
|
| 10. | As in the earlier designs there was no vertical separation of the wings, both mounted on the upper fuselage longerons.
