Summary: The New FAA Guidelines for IFR Departures
- Revised Obstacle Presentation: The FAA has changed how obstacle notes are presented to pilots, making it easier to understand and plan departures (6-12 main bullet points).
- Section Organization: Obstacle notes are now divided into two categories: low, close-in obstacles and take-off minimum obstacles.
- Low Close-In Obstacles:
- Located within one mile of the departure end of the runway.
- Heights up to 200 feet above the runway.
- Require pilots to see and avoid them during initial climb.
- Example: A tree at 636 feet MSL, 131 feet above the runway.
- Take-Off Minimum Obstacles:
- Located further out (up to 2.6 miles).
- Heights higher than 200 feet above the departure end of the runway.
- Require a steeper climb gradient.
- Example: A water tower at 1.8 nautical miles, 804 MSL.
- Climb Gradient:
- Standard climb is 200 feet per nautical mile.
- Required height above take-off minimum obstacles varies with distance from the runway.
- Weather Considerations:
- Good visibility and weather are required to see and avoid obstacles.
- Minimums for visibility: 300 foot ceiling, 2.25 statute miles.
- Departure Options:
- Depart early (crossing at 15 feet).
- Maintain standard climb if weather is good enough.
- Use performance calculations to ensure obstacle clearance.
- Runway End Crossing Height:
- Standard crossing height of 35 feet, now sometimes as high as 47 feet.
- Allows for easier takeoff planning using ground school and performance systems.
- AIM Section Updates: The amended AIM Section 5-2-9E provides detailed information on these changes.
