Obstacle clearance at certain airports can be enhanced by the use of bank angles greater than 15°. The following bank angles and heights may be used with Operation Specification authorization (in accordance with FAR 121.173 (f)). Any bank angles greater than the values shown below require additional specific FAA authorization:
- Height (above Departure End of Runway - ft) v Maximum Bank Angle (degrees)
- h>400 25 degrees
- 400>h>100 20 degrees
- 100>h>50 15 degrees
Lots of performance loss at 25 degrees. No doubt any FAA authorization would come only after a comprehensive planning and performance analysis.
