The basics of an aeronautical chart
Start with skyvector.com, World VFR
- come down the Merrimack River from Newfound Valley (2N2): just
elevation 510 and 1900' runway; note:
- surrounding mountains
- the river,
- towns by how lit up they are at night
- Concord, NH (CON): lighted 6000' runway and automated weather
- Manchester, NH (MHT): surrounded by Class C airspace
- Logan Airport (BOS)
- Hanscom (BED)
How will we find our way?
Fly from Hanscom to Bradley to go to the aircraft museum.
- don't put it on chart unless it can be seen from the air:
- pass Minute Man airport and then I-495
- a big radio tower, 2048' above sea level, 1250' above the ground,
- the Worcester airport, ORH
- the Mass Pike and intersectio with I-84, next to Southbridge airport
- Bradley, in the middle of two big cities; will be the dark hole in the middle at night
How High to Fly?
Helicopter from Los Angeles to Boston: descend to 300' to read the green highway signs.
- Hanscom at 132' above sea level
- big tower at 2048'
- Worcester Airport at 1009'
- Bradley at 173'
- maximum elevation figure: 1600, 2400, 1700, 1600 (rounded up to nearest 100')
Airspace to avoid?
- Class B over Hanscom
- wildlife refuges to the west of Hanscom
- restricted area R-4102 near Minute Man (shooting!)
- Worcester Class D airspace up to 3500'
Whom to talk to?
- Hanscom Tower
- Boston Approach (not shown)
- Bradley Approach (white box surrounded by magenta)
- Bradley Tower
- look at the white boundary around Boston; Terminal Area Chart available
- show helicopter and WAC charts (for planning a trip to Alaska)
- flying in the clouds? See World Lo
- flying a jet up high? See World Hi
Kids can Fly!
