Security where appropriate. The graphic figures in chapter 6, section 3
are also updated to reflect these new guidelines.
e. 6-3-6.
RESPONSIBILITY
6-3-8. EVALUATING EFFECT ON VFR OPERATIONS
Prior to the recent rule change, Part
77 provided that a proposed or existing structure was an obstruction to
air navigation if it was higher than 500 feet above ground level (AGL).
The FAA adopted the proposal that lowers the height of a structure
identified as an obstruction from above 500 feet to above 499 feet. This
change (including the graphic figures in chapter 6, section 3) is
updated to reflect the new guidelines.
f. 7-3-3.
STANDARD FORMAT
The automated Obstruction
Evaluation/Airport Airspace Analysis program replaced much of the manual

electronic processes. This change is updated to reflect the current
automation.
