How much obstacle clearance is provided during the circling segment of an instrument approach?
A minimum of 300 feet of obstacle clearance is provided in the circling segment.
Can you maintain your own terrain obstruction clearance?
When you fly under IFR, Air Traffic Control is responsible for providing you with traffic, terrain, and obstruction clearance. To ensure you maintain safe terrain and obstruction clearance, controllers will have you fly either a published procedure, or fly above the minimum instrument altitude (MIA).
How to determine the distance of an obstruction?
OBSTRACLE EVALUATION T-30-OBS Runway STRIP 60-m Close In Obstruction Tree Fence APPROACH OBSTRACLE EVALUATION T-31-OBS 60 m Close in obstruction APPROACH Use a hand-held clinometer to estimate slopes and possible penetrations If an object is suspected of being an obstruction 32
What should be the minimum obstacle clearance during an instrument approach?
Obstacle clearance in the initial phase. In the initial missed approach area, the minimum obstacle clearance shall be the same as for the last part of the final approach area except where the extension of the intermediate missed approach surface backwards towards the missed approach point requires less clearance.
What are the criteria for inspecting Obstacle Limitation Surfaces?
Describe Key Obstacle Limitations surfaces Identify the criteria for inspecting Obstacle Limitation surfaces Obstacle Limitation Surfaces Defines “Obstruction to Air Navigation.” Defines “Imaginary Surfaces.” Requires notice to AIS Obstacle Limitation Surfaces
What is the inner edge of an obstacle limitation surface?
Inner edge Distance from Threshold Obstacle Limitation SURFACES Inner Approach – A rectangular portion of the approach: – Inner edge coincident with inner edge of approach – Distance from threshold 60 m – Length 900 m – Slope 2.5% to 2% Transitional Surface Apch SurfaceApproach Inner Approach Obstacle Limitation SURFACES
