AIR TAXIS

GEOFENCING

NASA is leading the nation to quickly open a new era in air travel called Advanced Air Mobility, or AAM. The vision of 

AAM is that of a safe, automated, and affordable air transportation system for passengers and cargo in both urban and 

rural settings.

Air taxis are small, propeller driven aircraft capable of carrying passengers, that take off and land from locations called 

vertiports. Also, most of them are autonomous, meaning they do not have pilots onboard—a microcomputer installed on 

the air taxi controls flight. Since they operate above the roads, they can efficiently transport people because they can fly 

above traffic; consequently, this decreases traffic on roads.

Because of where air taxis and other 

unmanned aircraft will be flying, there will 

be places they cannot fly. For example, the 

airspace over airports or military bases needs 

to be kept clear. Failure to do so could result 

in collisions, which puts many people at risk.

Geofencing, which was developed by NASA, 

is a system that creates virtual fences around 

areas. When an unmanned aircraft approaches 

a geofenced area, a microcomputer onboard 

takes control and steers the aircraft away from 

that area. The microcomputer can also land 

the vehicle if it is unable to steer it away.

USING MATH ON MAPS

Have you ever tried to explain to someone where a certain place is? If you have, chances are you did so by explaining 

where the place is compared to another place. For instance, you might tell someone your school is located across the 

street from a park they know. The location you used for comparison is known as a reference point. 

You also use a reference point when graphing points on a coordinate plane. In this case, the reference point is the origin, 

the point at the coordinates (0, 0). If you graph a point at the coordinates (3, 5), you are saying to go three spaces to the 

right of the origin and five spaces up from the origin.

We can use this graphing system 

when comparing points on a 

map. If a grid is drawn on a map 

and an origin is chosen, places 

on the map can be located using 

coordinates. With higher math 

skills, the distance between points 

can also be easily determined. In 

figure 4, you can see a satellite 

picture with the airport and state 

capitol marked. Then, in figure 

5, you can see the same place 

changed into a map with a grid 

drawn on it.

In this activity you will be looking 

at Cheyenne, Wyoming. Cheyenne 

has two places that need 

geofencing. The first is Cheyenne 

Regional Airport and the second is the state capitol building. You will be using a map of Cheyenne with a grid over it to 

draw the geofenced areas.

PART 1

This student guide includes a coordinate system with the origin set to correspond with the maps shown. You can also 

use regular graph paper to complete this activity.

1. The geofenced area around the state capitol is a 2 x 2 box. The coordinates for the corners of this box are: (12, 4), 

(12, 6), (14, 6), and (14, 4). Plot these points on the graph and connect the four points to create a box. Shade in this 

area.

2. Because of its runways, the geofenced area around Cheyenne Regional Airport is a bit more complicated. The 

coordinates for the corners of the geofenced areas are: (9, 17), (13, 17), (13, 14), (26, 14), (26, 9), and (9, 9). Plot these 

points on the graph and connect the points to show the geofenced area. Shade in this area.

PART 2

You get a job in Cheyenne, Wyoming managing an air taxi service. Small, unmanned vehicles make up your fleet of air 

taxis. Your job is to determine the routes they need to fly to transport passengers around the city. In an urban setting like 

Cheyenne, air taxis cannot land or take off from anywhere they want. Instead, vertiports are established throughout the 

city for this purpose. Vertiports are buildings from which air taxis can land and take off.

1. Plot the following points and mark each with its corresponding letter. These points represent the vertiports in 

Cheyenne, Wyoming.

Point X Y

A 22 4

B 2 14

C 4 1

D 11 3

E 16 19

F 29 8

G 36 20

2. Your company’s headquarters are located by the vertiport represented by point A. This is where all of your air taxis 

are housed when not in use.

This morning, you want to send air taxis from point A to each of the other vertiports. On your graph, draw a line for 

each of the six paths. For each path, determine whether it can fly straight from point A to its destination without 

going into a geofenced area and write your answer below. Your graph should prove evidence for each.

From A to C: ________________________________

3. The city is planning on building a new vertiport at the coordinates (24, 18). Because of the geofenced area around 

the airport, you cannot send an air taxi straight from your headquarters to this new vertiport. 

So, you decide to create a waypoint where your air taxi can turn. The air taxi should be able to fly straight from 

headquarters to this point and then straight from this point to the new vertiport, all without entering a geofenced 

area. You need to find one point east (to the right) of the geofenced area that could act as the waypoint. Enter 

the coordinates of your point below, graph it, and show both legs on the air taxi’s flightpath as evidence that the 

waypoint you chose met the criteria.

Coordinates of the waypoint: ____________________________
