LKTRA37Z： Traffic is not allowed to fliehtplan across active military area FBZ
Flight Plan Buffer Zones (FBZ) Flight Plan Buffer Zones (FBZ) are established around AMC Manageable TSA / TRA for flight planning purposes. The purpose of FBZ is FPL validation only. The FBZ identification is the same as the TSA / TRA identificationaround which it is established and is supplemented by the letter “z”(for example, LKTSA1Z is the FBZ for LKTSA1). The activation time of the FBZ is identical to the activation time of therespective TSA/TRA. FBZ are AMC manageable.
但是该限制区的活动时间，并未在布拉格情报区LKAA的NOTAM中公布，需要根据捷克AIP提示，在捷克发布AUP（Airspace use plan）的专用网站AisView.rlp.cz上查询才能得知。查询结果如下：
34:1 Surface Clear Stipple Symbol On RNAV approach charts, a small shaded arrowhead shaped symbol from the end of the VDA to the runway indicates that the 34:1 Obstacle Clearance Surface (OCS) for the visual segment is clear of obstacles. The absence of the symbol indicates that the 34:1 OCS is not clear or a Visual Segment-Obstacles note is indicated on the chart.
Visual Decent Point (VDP) The Visual Descent Point (VDP), is shown by a bold letter “V” positioned above the procedure track and centered on the accompanying dashed line. (See example below.) The VDP is a defined point on the final approach course of a nonprecision straight-in approach procedure from which normal descent from the MDA to the runway touchdown point may be commenced.
