80Flying the Vectors ApproachWith “vectors to final” selected, the CDIneedle will remain off center until you’reestablished on the final approach course.With the approach activated, the map pagewill display an extension of the final ap-proach course in magenta (remember, ma-genta is used to depict the active leg of theflight plan) and “VTF” will appear as part ofthe active leg on the default NAV page (asa reminder that the approach was activatedwith vectors-to-final). In this example, we’llassume ATC vectors result in a rectangularcourse to intercept final, as follows:1. Within 30 nautical miles of KTOP, the GNS 430will switch from enroute mode to terminal modeand the CDI scale will transition from 5.0 to 1.0nautical miles, full scale deflection.2. If you haven’t already done so, activate theapproach (with vectors-to-final). This allows theGNS 430 to guide you to the final approachcourse. (See page 79.)3. ATC instructs you to turn left to a heading of025°. This places you parallel to the final approach course in the opposite direction. CDI needle deflectionis to the left.4. ATC instructs you to turn right to a heading of 115°.5. ATC instructs you to turn right to a heading of 175° to intercept the final approach course. As you con-verge with the final approach course the needle moves toward the center. (In the illustration at left, theneedle has not yet returned to the on-screen CDI, since your current position is still 1.7 nm right of thefinal approach course.){continued}PROCEDURESVectors-To-FinalApproach Example5DO NOT USE FORNAVIGATIONqnorpqpr
