Final answer:
Terrain and obstacle clearance during radar vectored instrument approach depends on altitude, navigation aids, and procedure design.
Step-by-step explanation:
When being radar vectored and cleared to fly an instrument approach, it is important to be aware that terrain and obstacle clearance depends upon several factors:
- Altitude: The minimum altitude for the specific segment of the approach must be followed to ensure terrain and obstacle clearance. This information is provided in instrument approach charts.
- Navigation aids: Proper use of navigation aids, such as VORs or GPS, helps maintain the correct track and ensure avoidance of obstacles.
- Procedure design: Instrument approach procedures are specifically designed to provide safe obstacle clearance. Following the published procedure precisely is crucial.
