vertical separation[′vərd·ə·kəl ‚sep·ə′rā·shən] (aerospace engineering) A specified vertical distance measured in terms of space between aircraft in flight at different altitudes or flight levels. (geology) The vertical component of the dip slip in a fault. vertical separation Semicircular system of separation.Separation between aircraft expressed in units of vertical distance (ICAO). It is the specified difference in flight levels between air traffic on conflicting courses. Outside controlled airspaces (CAS), the responsibility for this is with the pilot, but inside CAS, ATC (air traffic control) allocates levels, often following semicircular rules. However, it cannot be assumed that this will always be the case. Below flight level 300, the aim is to keep a 1000-ft separation and above this a 2000-ft separation. Various types of vertical separations are indicated in the illustrations. |
