This task looks at deciding where to divert a plane following an incident. It uses simple GIS tools of plotting data, doing a buffer search then a filter search. Time is of the essence in this type of event so shows the ability to handle large sets of data quickly.
This task could be used with a volcanic ash cloud event, bird strike, engine malfunction, severe weather incident.
Log in to your ArcGIS online account and open a new map. Then add a layer : search for layers in
ArcGIS online: airports.
Choose the USDOT FAA 5010 Airport Features – NFDC Airports layer as it has all the information you will need such as the ability to filter the data and having the required information for the investigation.
This task uses a readily accessible data set based on USA data. This example uses http://www.flightradar24.com/ to look at real events. By clicking on a plane you can get it route and plane information.
This example uses flight DL905. You are flying from Las Vegas to Minneapolis St Paul on DAL Flight
501. Over South Dakota you experience technical problems that means you must land as soon as possible. First you will need to find the requirements of the airplane flying.
Search airplane specification in Google such as the Boeing 757 series

Here are the requirements for the Boeing 757
Add the route as a map note as a straight line from start to finish. At a point around Pierre, South
Dakota an incident happens you now have only 300km worth of fuel so first you need to find what airports are within 300k from point. You then need to find an airport with a long enough runway.
The distance of runway needed will be in the specifications.
Create a buffer around this point by clicking on the incident point then perform analysis, use proximity>create buffers> type in 300 km> then click run analysis
Find existing locations with the given buffer area by carrying out the following spatial analysis:
Perform analysis> find locations> find existing locations>add expression where airports lie completely within the buffer area. Then ADD

Then run analysis and it will give you a result of 16 airports. However which are big enough to land the plane
Now carry out a filter of these airports to see if any of them is longest enough for the airplane. You will need to find the landing length needed from specs. With this exam its 7800 so carry out a filter of the data where longest runway is at least 7800ft
With this example there are 4 airports
Now to find the nearest one you by either measuring the points visually. Look at the airport details which will be a better location to land. With this example the airbases at Rapid City is probably better as it has two options both a public and military airport.
NOW Repeat this task with a different flight. Produce your report giving your reasons for your choice.
