ADO 2 3 Sets of Aviation Standards Airport Imaginary Surfaces - Part 77 Airport Design Standards (A.C.s) Terminal Instrument Procedures (TERPS) 3
ADO 3 3 Airport Assurances -Assurance 19, Operation and Maintenance: The sponsor will not cause or permit any activity or action on the obligated airport that would interfere with its use for airport purposes. - Assurance 20, Hazard Removal and Mitigation: The sponsor will prevent the establishment or creation of any future airport hazard. - Assurance 29, Airport Layout Plan (ALP): The sponsor will not make or permit any changes to the airport or any of its facilities that are not in conformity with the FAA-approved ALP or which might in the opinion of the FAA adversely affect the safety, utility, or efficiency of the airport. 4
ADO 4 14 CFR Part 77 Defines “obstructions to air navigation” Requires notice to FAA prior to construction Procedures for studies and determinations Hazards to Air Navigation 5
ADO 5 Part 77 Imaginary Surfaces Standards for determining obstructions Applies to objects :  natural growth  terrain  permanent or temporary construction or alteration  including temporary equipment used for construction 6
ADO 6 Obstructions and Hazards Obstruction - any object that penetrates any of the Imaginary Surfaces Hazard - Obstruction that is determined through an airspace study to substantially affect the safe passage of an aircraft All Hazards are Obstructions Not all Obstructions are Hazards 7

ADO Airport Design Standards Runway Safety Areas (RSA) Runway Safety Areas (RSA)  Rectangular ground surface around runway Runway Object Free Area (ROFA) Runway Object Free Area (ROFA)  Rectangular ground surface around runway and safety area Obstacle Free Zone (OFZ)Obstacle Free Zone (OFZ)  Volume of airspace above runway 20
ADO Airport Reference Code (ARC) The ARC is a coding system to relate airport design criteria to the operational and physical characteristics of the aircraft intended to use the airport. The ARC is a coding system to relate airport design criteria to the operational and physical characteristics of the aircraft intended to use the airport. A. Aircraft approach category (relates to aircraft approach speed) B. Airplane design group (relates to airplane wingspan) 21

ADO Runway Safety Area Width and length based on the ARC (both approach and wingspan) Found in Tables 3-1, 3-2, & 3-3 in AC 150/ AC 150/ Width and length vary (based on ARC) from 60 ft either side of centerline and 240 ft beyond runway end to 250 ft either side of centerline to 1000 ft beyond the runway. 23
ADO Runway Safety Area 9 27 Width varies from 120 ft wide (60 ft either side of Center Line) to 500 ft, depending on aircraft design group. Length = 2 x Width 24
ADO RSA Object Clearing Criteria Free of objects except those fixed by function:  objects over 3 inches must be frangible at no more than 3 inches  Manholes must be constructed at grade Personnel and Equipment may not be in RSA during aircraft operations 25
ADO Runway Object Free Area Two dimensional ground area Surrounds runways, taxiways, and taxilanes Clear of Objects except those fixed by function 26
ADO Runway Object Free Area Width ranges from 250 ft wide (125 ft either side of CL) to 800 ft wide Length ranges from 240 ft long to 1000 ft 27
ADO ROFA Clearing Criteria Acceptable:  Objects for air navigation  Aircraft ground maneuvering purposes  Taxiing and holding aircraft Not Acceptable :  Objects not essential for air navigation or aircraft maneuvering purposes  Parked aircraft  Agricultural Operations 28
ADO Comparison of RSA with ROFA ARC C-III, Airplane Design Group III (Wingspan 79 ft to 117 ft) and Approach Category C (121 knots to 140 knots) e.g. B-737 OFA ft wide 1000 ft beyond end of runway RSA ft wide 1000 ft beyond end of runway 29

ADO FILING FAA FORM https://oeaaa.faa.gov/oeaaa/external/portal.jsp -If first time, register as new user first then log in to file your airspace case proposal -Upload your sketch, in pdf format -Verify your case by mapping -instructions included in the portal site -30 days for FAA to issue determination -Determination good for 18 months -Before case expires, can be extended for another 18 months 47
ADO Common mistakes -Geographical coordinates are not correct or are not of sufficient accuracy, Lat/Long coordinates need to be to the nearest 0.01 sec -Case filed to late, usually occurs with temporary cranes -Not enough points given for FAA to properly evaluate 48
