AVIATION & AERONAUTIC CALCULATOR
Obstacle Clearance Gradient
A precise tool.
What is the Obstacle Clearance Gradient & How does it work?
The Obstacle Clearance Gradient (OCG) is a critical parameter in aviation and aeronautics, ensuring that aircraft have sufficient clearance over obstacles during takeoff and landing. This gradient helps in planning safe flight paths and determining the minimum obstacle-free area required.
The OCG is typically calculated based on the aircraft’s performance characteristics, such as its climb rate and the specific procedures outlined by aviation authorities like the FAA or ICAO.
OCG = frac{H}{D}
H = Height of obstacle clearance
D = Horizontal distance from the runway threshold to the point directly above the obstacle
D = Horizontal distance from the runway threshold to the point directly above the obstacle

Frequently Asked Questions
What is Obstacle Clearance Gradient in aviation?
The Obstacle Clearance Gradient (OCG) is a safety parameter that ensures aircraft have sufficient clearance over obstacles during takeoff and landing.
How do I calculate the OCG for my aircraft?
OCG is calculated by dividing the height (H) of the obstacle by the distance (D) from the runway threshold to the point where the aircraft reaches that height.
Why is OCG important in aviation?
OCG is crucial for planning safe flight paths and determining the minimum obstacle-free area required, ensuring aircraft safety during takeoffs and landings.
What factors affect the OCG calculation?
Aircraft climb rate, specific procedures outlined by aviation authorities like FAA or ICAO, and the height of obstacles all factor into the OCG calculation.
Can you provide an example of how to use this calculator?
Input the height of the obstacle and the distance from the runway threshold to the point where the aircraft reaches that height. The calculator will then compute the OCG for you.
