Why implement such a process

Why Implement Such A Process?

  • The role and importance of airport and aeronautical data in meeting the safety, regularity and efficiency of air navigation changed significantly with the implementation of area navigation (RNAV), required navigation performance (RNP) and airborne computer based navigation systems.


Answer

Answer …

  • To provide a common platform for the collection, maintenance, and dissemination of airport and aeronautical information and sharing of the data for improved efficiency of airport operations for both the sponsor and the FAA.

  • Current initiatives within aviation industry (moving maps, electronic flight information, advanced avionics) require a data centric airport environment, as opposed to the traditional product based environment.


Why implement such a process1

Why Implement Such A Process?

  • To meet the challenges of the changing role of aeronautical data in the system, the FAA needed to rethink the way it collects, stores, and maintains the data about airports.

  • We need to focus on managing our airport and aeronautical data.


Airport surveying gis program vision

Airport Surveying/GIS Program Vision

“All I need to know about airport data … I learned in kindergarten.”

In other words … data sharing

Provide an interoperable web-based system for the collection, management, maintenance and sharing of airport data addressing the needs of the FAA lines of business and the individual airports collectively rather than individually.


Organization of ac 150 5300 18b

Organization of AC 150/5300-18B

  • Though it looks daunting from the outside … it’s not really that bad!

  • The AC has five (5) chapters and appendices

  • Chapter 1 discusses general survey guidance and specifications

  • Chapter 2 discusses specific survey specifications and standards

  • Chapter 3 discusses geospatial standard and specifications (GIS rules)

  • Chapter 4 discusses data translation and existing data

  • Chapter 5 discusses specific about the airport features

  • Chapter 1 – 4 cover about 100 pages the rest is chapter 5!


New philosophy on airport surveys

New Philosophy on Airport Surveys

  • AC 150/5300-18 is designed to collect data about the airport as a whole rather than as a group of individual projects.

  • Since most everything on an airport is interconnected or has a relationship to other things and these relationships should be preserved.

  • Data collection projects should build on one another.

  • Data provided as part of a design should be incorporated into the airport data set and later verified rather than collected new.

Types of surveys

Types of Surveys

  • Under the previous standard (FAA 405) there were as many different types of surveys

  • These multiple types did not always provide the information required and most were incorrectly based on 14 CFR 77

  • AC 150/5300-18B has only two types of “obstruction surveys” … it is a single multifaceted surface not individual pieces

    • Vertically Guided

    • Non-Vertically Guided


Vertically guided airport airspace analysis surface

Vertically Guided Airport Airspace Analysis Surface

  • These specifications support the airport’s planning and design activities for the development of vertically guided instrument approaches such as ILS, PAR, MLS, LPV, TLS, RNP and Baro/VNAV


Non vertically guided airport airspace analysis surface

Non-Vertically Guided Airport Airspace Analysis Surface

  • Use the following specifications and associated figures to complete object identification on and surrounding airports to runways designed for visual or non-vertically guided (NVG) operations (Lateral Navigation (LNAV), Localizer Performance (LP), VOR, NDB, Localizer, Localizer Directional Aid (LDA), etc.)


The new surfaces are bigger and cost a lot more

The New Surfaces Are Bigger And Cost A Lot More!

  • 6,000-runway at an airport with one runway

  • Vertically Guided Airport Airspace Analysis Surface (-18B) is …

    42.1839487 sq miles

  • Full Part 77 (Approach Surface to 50,000 feet) is …

    56.8643939 sq miles

  • Part 77 (Approach surface shortened to 20,000 feet) is …

    31.4683884 sq miles


New philosophy on airports surveys

New Philosophy on Airports Surveys

Runway Extension Example

  • A position an elevation of the new runway end is determined during the design phase

  • These values can and should be used to coordinate the changes to instrument procedures once the design is finalized.

  • Most if not all of the information for procedure design is in the design … runway end position, elevation, touchdown zone elevation, elevation of centerline abeam navigational aids etc.

  • Once construction is complete these numbers need to be validated … remember what validation is?

  • The obstruction analysis can also be completed off these numbers the key is maintaining the analysis (new objects) once it is completed until the runway is done.

Types of surveys1

Types of Surveys

  • Surveys are on completed on airports for many different reasons

    • Boundary

    • Construction

    • Utilities

    • Obstruction

  • Each served a single purpose, each was not coordinated sometimes collecting similar or the exact same data

  • Some even happening at the same time!


Other types of surveys

Other Types of Surveys

  • AC 150/5300-18B for the first time discusses standards for other types of surveys relating to or happening on Airports, most of which you are familiar with

    • Boundary/Land Use

    • Sub Surface Utility Engineering

    • Topographic

    • Airport Mapping Database

    • Construction

    • Airport Pavement


Cat ii iii operations area surveys

Cat II/III Operations Area Surveys

  • The area of consideration is

    • 3000 feet long

    • 400 feet wide

    • Centered on the runway centerline extended

  • In this area provide only terrain data

  • Classify the terrain using the Contour feature type in Chapter 5.


Cat ii iii operations area surveys1

Cat II/III Operations Area Surveys

  • This is a special topographic survey completed to provide specific information for the installation, maintenance and development of instrument procedures for Category II and III operations.

  • The purpose of this area is to define the terrain within the area, which could provide for false radar altimeter readings. The collection of this information meets the requirements of the International Civil Aviation Organization

  • (ICAO), Annex 15 regarding Area 4.

Arp policy on permanent geodetic control pacs sacs

ARP Policy on Permanent Geodetic Control (PACS/SACS)

AC 150/5300-16, paragraph 2.2

Airports Requiring Geodetic Control Monumentation

  • Permanent Control. FAA Regional Airports Divisions will determine which airports require permanent geodetic control monumentation in the form of PACS or SACS based on the activity (operational or proposed future construction) at the airport. However, for all airports in the National Plan of Integrated Airport Systems (NPIAS), we strongly recommend that at least the PACS be established.


Why do we require imagery

Why Do We Require Imagery?

  • The role and importance of airport and aeronautical data in meeting the safety, regularity and efficiency of air navigation changed significantly with the implementation of area navigation (RNAV), required navigation performance (RNP) and airborne computer based navigation systems.

  • There are 2 reasons we require imagery.

    • The primary reason we require imagery for projects involving safety critical data is to ensure the quality of the aeronautical information collected.

    • Secondly, we feel that the use of imagery is an accurate and potentially cost saving method of collecting this type of data.

  • Current initiatives within aviation industry (moving maps, electronic flight information, advanced avionics) require a data centric airport environment, as opposed to the traditional product based environment.


Independent verification and validation of data

Independent Verification and Validation of Data

  • Due to the critical nature of some airport features, the FAA requires their independent verification and validation by the Aeronautical Survey Program of the National Geodetic Survey or a designated representative. Typically, these features are those associated with the airport’s movement areas, navigational systems or those affecting navigable flight such as objects surrounding the airport.

  • NGS reviews the Safety Critical Data


What is safety critical data

What is Safety Critical Data?

  • ICAO Annex 15 defines data as critical when “there is a high probability when using corrupted critical data that the continued safe flight and landing of an aircraft would be severely at risk with the potential for catastrophe.”

  • Today’s navigational databases and advanced avionics in aircraft require the highest integrity data …


Verification vs validation

Verification vs. Validation

  • Verification: The confirmation by examination and provision of objective evidence that the specified requirements are fulfilled. Verification is necessary to ensure the data set accurately represents the specifications and is uncorrupted.

  • Verification is testing against an independent measurement set (different tools or software)

  • Validation is the confirmation by examination and provisions of objective evidence showing the data set meets the particular requirements of the intended use. The purpose of the validation process is to demonstrate the data set has sufficient overall integrity to satisfy the requirements for its intended application. Validation answers the questions “is the data reasonable when compared against known data” and “does it meet the identified need.”

  • Validation means is the data reasonable and acceptable


Verification vs validation1

Verification vs. Validation

Validation (done by the system) is … you built the product right

Verification (done by examination) is … you built the right product!

Do you still call it a 405 survey get up to date on the new faa ac 150 5300 18b

What is Needed?

  • Under the Airport Surveying-GIS Program, the collection of airport data consists of …

    • The use of existing data

    • The collection of new data or verification of existing data

  • How do you (or the airport sponsor) determine what data is required?

    • AC 150/5300-18B, Table 2-1 provides information on what is required.

Data Collection Requirements Matrix


Attributes

Attributes

  • Attributes add alphanumeric descriptors to the geometry of a feature.

  • Attributes typically contain information such as the name, type, or condition of a feature.

  • For example, the attributes of a runway include its designator (e.g., 15R/33L), material type (e.g., concrete) and length (e.g., 6,500 feet).

  • In this standard attributes are typed in lowerCamelCase letters.

  • Airport sponsors should work with the consultants to completely attribute each feature submitted to the FAA.


Attributes1

Attributes

  • UDDF (Universal Data Delivery Format) delivered data … it was an outline, it did not tell the whole story!

  • This runway entry only shows the geographic position (latitude/longitude, true bearing, touchdown zone elevation, and four (4) elevation points on an 11,500 foot runway.


What attributes are required and which are optional

What Attributes are required and Which are Optional?

  • Airport Surveying-GIS program looks at the airport as a whole rather a group of disconnected individual parts…so it should be attributed as a whole.

    The SOW determines who does what .


What attributes are required and which are optional1

What Attributes Are Required and Which Are Optional?

  • All attributes and features located on the airport are required …

  • Some are required from the surveyor

  • Others are required of the sponsor or their consultant

  • The SOW determines who does what


Domain values or enumerations

Domain Values or Enumerations

  • Sometimes it is necessary to limit the range of values for an attribute

  • In AC 150/5300-18B use the domain for an attribute to list acceptable values

  • Two Types

    • Code List – provides values but allows others to be input and still be compliant

    • Enumeration List – provides a listing but does not allow users to add to the list … Airports GIS uses enumeration lists.


How do you tell that an attribute is an enumeration

How Do You Tell That An Attribute Is An Enumeration?


Reading the enumeration table

Reading The Enumeration Table


Using existing data

Using Existing Data

  • Many airports have developed and collected data over the years through different projects or planning efforts. This data exists in many forms from drawings in a CADD system, to individual records in databases or through a hardcopy management system

  • Why should we not reuse this data … if its traceable to the source?


Establishing the number of field verification points

Establishing the Number of Field Verification Points

  • The number of required field verification points is dependent on the size and complexity (volume of air traffic) of each airport

  • Using the table (4-3) in conjunction with the acreage and operations information available within an airport’s 5010 form, intersect the columns and rows to establish the number of field verification points required to quality control the legacy datasets for an airport.


Establishing the number of field verification points1

Establishing the Number of Field Verification Points

  • Chicago O’Hare has 7,280 acres and 958,643 operations requiring 180 points

  • Nashville International has 3,900 acres and 213,287 operations requires 120 points

  • 213,287 ÷ 958,643 = 0.222488455

  • 120 x 22 % = 26.4 + 120 = 146.4

    or

  • 150 x 0.222488455 = 33.4 (150 – 33.4) = 116.6

  • Δ = 3.6 and 3.4 so yes, the matrix makes sense.


Error analysis

Error Analysis

  • From reviewing similar types of features, an analysis of the errors can show when there are systematic errors that can be corrected or random errors that require data be verified or recollected to meet the accuracies required in AC 150/5300-18B, Chapter 5.


Data migration tool

Data Migration Tool

  • The FAA developed the Data Migration Tool (DMT) to assist the data provider in translating their data to comply with the standards established in this AC.

  • The DMT requires Autodesk Civil 3D 2008™ to run. Versions of the DMT for use with other CADD and GIS software will be made available when they are developed and tested.

  • Data in other formats can be imported into Civil Design 3D for use with the DMT

  • The DMT can be downloaded from the Airports GIS web site.

Why do we required survey and quality control plans

Why Do We Required Survey and Quality Control Plans?

  • If you have to surveyors measure the same line or determine the same position, you will get two different answers.

  • The differences will be small but there will be differences based on personal experience and other errors inherent to measurement.

  • Survey and Quality Control Plans allow the FAA and NGS as the government’s technical representative to review the consultant’s procedures, equipment, methods and understanding of the requirements prior to work beginning.


Submitting the plans

Submitting the Plans

  • Submit all plans for evaluation using the Airports GIS system.

  • This allows for everyone (the airport sponsor, the ADO/Region, State DOT, FAA HQ, NGS) to see the plans in a single place.

  • It provides a system for tracking when something was received ands when it was reviewed and approved.

  • It provides traceability of the information for use in future projects.


Last words

Last Words …

  • It really doesn’t matter how they collect the data, what coordinate system or unit of measure they use, as long as they tell us what it is.

  • It follows the old adage of instruction …

    • Tell them what you are going to tell them (Survey and Quality control Plan).

    • Tell them (The data and associated deliverables)

    • Tell them what you told them (Final Report)
