private-use airports and civil public-use airports and to airport inspectors for the purpose of 

providing airport data to the Federal Aviation Administration (FAA) using FAA Forms 5010-3 and 

5010-5. This AC is organized so as to minimize the amount of material that the proponent needs 

in order to correctly complete and submit Forms 5010-3 and 5010-5 to the FAA. 

APPLICATION 

This AC applies to the proponents of new civil and joint-use public-use airports and new civil 

private-use airports, and to FAA Regional Airports/ADO personnel, and FAA, state and 

contractor airport inspectors. 

INTERNET ACCESS 

This AC is available on the Internet at the FAA Office of the Associate Administrator for Airports 

(ARP) home page on the Internet’s World Wide Web (www). The direct Internet address is

SECTION 2. AIRPORT MASTER RECORDS 

Airport Master Record refers to all four of the forms used in the conduct of the Airport Safety 

Data Program; specifically, FAA Forms 5010-1, 5010-2, 5010-3, and 5010-5. 

The Forms 5010-3 and 5010-5 are “blank” forms and are used to report aeronautical data on a 

newly proposed or newly constructed airport. These two forms are addressed in this AC. 

The Forms 5010-1 and 5010-2 are forms on existing airports and contain aeronautical data on 

existing airports; accordingly they are not available in the FAA web site in a PDF-fillable format. 

These two forms are computer reports that contain aeronautical information about a landing 

area. The data on the forms are derived from the NASR database. 

Both forms contain data elements that are preceded by the “greater than” symbol “>” and this 

symbol may be disregarded. 

Office of Management and Budget (OMB) approved the collection of the aeronautical 

information on these forms in OMB control number 2120-0015. The forms are available in the 

FAA web site in a PDF-fillable format at http://forms.faa.gov. 

2.1 FAA Form 5010-1 Airport Master Record contains aeronautical data describing the 

physical and operational characteristics of civil public-use airports, joint-use military airports, 

and private-use military airports that are active and in the NAS. This form is a computer report of 

airport data derived from the NASR database as of the AFD effective date shown on the form. 

2.2 FAA Form 5010-2 Airport Master Record contains aeronautical data describing the 

physical and operational characteristics of civil private-use airports that are active and in the 

NAS. This form is a computer report of airport data derived from the NASR database. 

2.3 FAA Form 5010-3 and 5010-3.pdf Airport Master Record is a blank form or 

downloadable blank form to be used by FAA, State and contractor airport inspectors and other 

Regional Airports Division/ADO personnel to provide the initial physical inspection report on a 

newly constructed or newly reported civil public-use airport. Form 5010-3.pdf is available at 

http://forms.faa.gov. 
5/20/2004 AC 150/5200-35

2.4 FAA Form 5010-5 and 5010-5.pdf Airport Master Record is a blank form or 

downloadable blank form to be used by the proponents of private use airports to provide an 

initial report on a newly constructed or newly reported civil private-use airport. Form 5010-5.pdf 

is available at http://forms.faa.gov. 

SECTION 3. NEWLY ESTABLISHED AIRPORTS 

3.1 Activation of new Public Use Landing Areas 

The airport proponent of all proposed new public-use airports should contact the nearest FAA 

Regional Airports Division or ADO and prepare a FAA Form 7480-1, Notice of Landing Area 

Proposal, downloadable from http://forms.faa.gov/forms/faa7480-1.pdf. This form is 

submitted to the appropriate FAA Regional Airports Division or ADO. This may be the first 

information available to the FAA regarding proposals for new general aviation public-use 

airports. 

When the FAA receives the FAA Form 7480-1, the FAA initiates an aeronautical study. 

After the FAA completes the aeronautical study, the FAA issues an airspace determination letter 

to the proponent. There are three airspace determinations. They are: no objection, no objection 

with conditions, and objectionable. When the airport becomes operational, the FAA or state 

airport inspector should then inspect the airport and submit a completed Form 5010-3 to AAS330. AAS-330 will review the inspection data for accuracy, assigns the airport a site number, 

and forward the Form 5010-3 to the Office of Air Traffic. Air Traffic will enter the airport into the 

FAA’s National Airspace System. 

If the FAA Regional Airports Division, ADO, State or contractor personnel are unable to 

physically inspect a new public-use airport that office should advise the airport proponent to 

complete and submit FAA Form 5010-3.pdf to AAS-330 following the guidance provided in this 

AC. 

Contact the State Aviation Agency for guidance regarding State aviation requirements. 

3.2 Activation of new Private Use Landing Areas 

The airport proponent of all proposed new private-use airports should contact the FAA Regional 

Airports Division or ADO and prepare a FAA Form 7480-1, Notice of Landing Area Proposal, 

downloadable from http://forms.faa.gov/forms/faa7480-1.pdf. This form is submitted to the 

appropriate FAA Regional Airports Division or ADO. This is usually the first information available 

to the FAA regarding proposals for new private-use airports. 

When the FAA receives the FAA Form 7480-1, the FAA initiates an aeronautical study. 

After the FAA completes the aeronautical study, the FAA issues an airspace determination letter 

to the proponent. There are three airspace determinations. They are: no objection, no objection 

with conditions, and objectionable. This letter notifies the airport proponent of the results of the 

FAA aeronautical study and includes a blank Form 5010-5. The letter advises the proponent to 

fill out the Form and submit it to the FAA when the airport becomes operational. 

When the Form 5010-5 is received from the proponent, the FAA Regional Airports Office or 

ADO will assemble and provide to AAS-330 a “5010 package” containing at a minimum a copy 

of the airspace determination letter, a copy of FAA Form 7480-1, and the original Form 5010-5. 
AC 150/5200-35 5/20/2004 

5

AAS-330 will review the completed FAA Form 5010-5 for reasonableness and accuracy. When 

necessary, AAS-330 will seek clarification of the information submitted by contacting the airport 

proponent or the appropriate FAA Regional Airports Division or ADO. 

AAS-330 then assigns a site number to the landing area and transmits the original FAA Form 

5010-5 to the Office of Air Traffic. Air Traffic will enter the airport into the FAA’s National 

Airspace System. 

Contact the State Aviation Agency for guidance regarding State aviation requirements. 

SECTION 4. DATA ELEMENTS 

This section contains data elements and a description and acceptable entries for reporting each 

data element on the Airport Master Record, FAA Form 5010-3 and Form 5010-5. 

For private-use airports, some of the data elements listed in this section do not apply. They are 

identified in the “DATA” column with the note “This element is not required for civil private use 

airports.” The data elements that do not apply to private use airports are also omitted in Form 

5010-5. 

For public-use airports, all the data elements in this section apply and all the data elements are 

shown on Form 5010-3. 

If you need further information or assistance on filling out Form 5010-3 or 5010-5 or in

HARD SURFACE RUNWAYS 

Approach Ratio Calculation: 

Distance from the runway end (data element 55) minus 200 

feet, divided by the height above the runway end (data 

element 54). 

NON-HARD SURFACE (UNPAVED) RUNWAYS 

Approach Ratio Calculation: 

Distance from runway end (data element 55) divided by the 

height above the runway end (data element 54). [Hence there 

is no need to subtract 200 feet.] 

Remember to always round down when the division of the 

distance by the height does not result in a whole number. 

Therefore a slope of 19.9 is rounded down for safety to 19. 

APPROACH SLOPE FOR DISPLACED THRESHOLDS 

If an obstruction penetrates the approach slope to the 

displaced threshold and the obstruction is not the same one 

identified as the controlling obstruction to the runway end, it

declared available and suitable for the ground run of an 

airplane taking off. 

>61 TAKE OFF DIST 

AVBL (TODA) 

This element is 

not required for 

civil private use 

airports. 

Enter the takeoff distance available. It is the TORA plus the 

length of any remaining runway or clearway beyond the far 

end of the TORA. 

NOTE: The full length of TODA may not be usable for all 

takeoffs because of obstacles in the departure area. The 

usable TODA length is aircraft performance dependent and, 

as such, must be determined by the aircraft operator before 

each takeoff and requires knowledge of the location of each 

controlling obstacle in the departure area. 

>62 ACLT STOP 

DIST AVBL 

(ASDA) 

This element is 

not required for 

civil private use 

airports. 

Enter the accelerate-stop distance available. It is the runway 

length plus the stopway length declared available and suitable 

for the acceleration and deceleration of an airplane aborting a 

takeoff. 

Stopway: A defined rectangular surface beyond the end of a 

runway, prepared or suitable for use in lieu of runway, to 

support an airplane without causing structural damage during 

an aborted takeoff. The length of this surface is used for the 

ASDA calculation of declared distances. 

NOTE: The term “overrun” is used only in reference to military 

airports. 

>63 LNDG DIST Enter the landing distance available. It is the runway length 

declared available and suitable for a landing airplane.
