FAR Part 77 is one of the most important aspects that must be
considered when operating an airport. A duty of airport operations is to keep a close eye on what is happening around the field. It is very common to see unauthorized cranes just boom up. They must have an airspace study performed. If construction is planned within 20,000 ft of an airport or exceeds 200 ft in height, a study must be performed. The form a contractor is required to fill out for this study, FAA form 7460-1 can be downloaded here.
For those interested in how the primary and transitional surfaces around an airport are designated and defined I have provided two videos. For more information please go to www.myairportoperations.com

As part of your airport layout plan drawings, there is a separate drawing that should show the Part 77 surfaces for your airport, and another that show the approach profiles for each runway. Depending upon the consultant that did the drawing, some will provide detailed height information in the vicinity of the airport. You can give generalized guidance about allowable heights based on that drawing, or you can perform the calculations described in the ACE-OPs modules or what you've learned from attending one of my training courses. For proper determination, however, you will need to file the 7460 per the grant assurances, as Glen has stated. I recommend all operations personnel become familiar with the ALP and part 77 and approach profile drawings, as they provide you with the standards you are comply with at your airport.

For operators or construction contractors who don't want to handle the process themselves with the FAA, Jeppesen is one company that will do it for you.
