self deconfliction. Ireland In Ireland, airspace is divided into classes A, C and G only. Class A: This high-level en route controlled airspace is used predominately by commercial and passenger jets. Only IFR flights are permitted and they require ATC clearance. Class A airspace exists in the Northern Oceanic Transition Area (NOTA) and the Southern Oceanic Transition Area (SOTA). Class C: This is the controlled airspace above 7,500 feet and surrounding major airports. Both IFR and VFR flights are permitted and both require ATC clearance and separation service is to be provided by ATC. Class G: This airspace is uncontrolled. Both IFR and VFR aircraft are permitted and neither requires an ATC clearance. Italy Class A is used for Rome and Milan TMAs Class B is not used. Class C is used in all airspace above FL 195, and in Military Control Zones above FL 195, to FL 460 excluded. Class D is used for controlled zones and other TMAs. Class E is used for airways from MEL to FL 115. Class F is not used. Class G is used in all other airspaces, and above FL460 Kenya Classes A, C, D, G are used in Kenyan airspace, alongside unclassified military operation areas which are defined in Restricted Areas and Prohibited Areas, and are controlled by military air traffic control units. Class A is used above FL145, except in areas where ground level exceeds FL145, in which case class A airspace exists above AGL and class G below. Class C airspace is used exclusively in the Nairobi TMA and CTR. Class D airspace is used in all other aerodrome airspaces. Class G airspace exists everywhere else, particularly between ground level and AGL. Lithuania In Lithuania, Classes A and B are generally not used at all. Classes C and D are used in the following areas of controlled airspace of the Republic of Lithuania: in control zones (CTR) in terminal control areas (TCA) in control area (CTA) in upper control area (UTA) Mauritius Classes A, C and G are used in Mauritius. Class A airspace exists within the entire Mauritius FIR (Flight Information Region), above FL245. Class C airspace exists within 150 nautical miles of Mauritius, below FL245 (Mauritius TMA and CTR). Class G airspace exists in all other areas of the Mauritius FIR. Netherlands In the Netherlands, a relatively large part of the country is Class A airspace. Near Amsterdam,
