Pilots experience difficulties to be constantly aware of the type of airspaces crossed while preparing for an approach and looking outside in compliance with the “see and avoid” rule.
One of the critical safety issues regarding class E airspace is the speed of modern aircraft and the ability of the human eye to detect aircraft in a clear futureless sky.
IFATCA Policy is:MAs shall urge ANSPs to co-ordinate and harmonise with all neighbouring states their national airspace classification, in accordance with ICAO Annex 11 Appendix 4, to permit safe and efficient operating conditions to all airspace users and air traffic controllers. The appropriate authority should, as required, review airspace classifications and adjust accordingly to support air traffic operating in the airspace. Local operational ATCOs shall be involved in any airspace classification process. |
