RNAV routes in Finland require RNAV 5 capability. Supported sensors are only GNSS and DME/DME.
 

2.1. The current permanent ATS route network consists of all permanently designated routes which are not subject to daily management and which can only be closed under specific conditions known well in advance e.g. by AIP SUP or NOTAM, for large scale military exercises.
 

2.2. The advance information of the closure of permanent routes will always be promulgated by an AIS publication (AIP SUP, NOTAM). The actual permanent closure will be published by AUP/UUP. Temporarily the route availability may also be subject to restrictions due to the activation of permanent restricted or danger areas. The activation effect to the route availability is given in column 8.
 

2.3. When the available PERM category RNAV ATS routes are affected by temporarily reserved airspace, radar vectoring on ATC instructions is provided to avoid active areas.
 

Note: See section ENR 1.9 also.

3.1. Conditional Routes (CDR) are designed to complement the permanent ATS route network and to allow flights to be planned on ATS routes, or portions thereof, that are not always available. CDR are generally established through areas of potential temporary allocation identified under the generic term ‘AMC-Manageable Areas’ (including TSA and manageable R and D areas).

Note: The term ‘AMC - Manageable Areas‘ includes temporary segregated areas (TSA), temporary reserved areas (TRA) and Cross Border Areas (CBA) described in section ENR 5.2.
 

3.2. CDR are divided into three different categories according to their foreseen availability, their flight planning potential and the anticipated level of activity of the associated AMC Manageable Areas.The following three categories are in use:

Note: A CDR can be established in one or more of the three categories described below.
 

3.2.1. Category one (CDR 1)

CDR 1 are permanently plannable during the times published in AIP.
