The SN10 Database

4.2 Point Short Names and Order of Point Display

The SN10 refers to points using a seven-character name. Preparing a database

requires choosing this short name with care, so you can quickly find it in the

alphabetically ordered list of points.

Many contests provide a numbered set of turnpoints. The SN10 sorts all points whose

short name begins with a number together, after all the names that start with an

alphabetic character. The numbers are sorted properly, for example ordered like:

Alpha

… (names starting with alphabetic characters)

Zulu

1StartN

… (any names starting with the numbers 2 through 9, in order)

10BigCu

… (any name starting with the numbers 10 through 19, in order)

20Cloud9

Names can also contain a limited number of non-English characters, in particular

characters with accents. These sort next to the character without the accent.

4.3 Point Elevation

If possible, the point elevation should be provided in the database. The SN10 will work

fine if the elevation is missing from a point, but you won’t get automatic setting of the

arrival altitude FIN when you set this as a new finish point, and the Alternates page will

give an MSL arrival altitude instead of amount above or below glideslope.

4.4 Point 5-Line Description

When a database is prepared, descriptive information of up to 5 lines (16 characters

each) can be provided for each point. This is typically used to include the full name of

the point without abbreviation, radio frequencies, and runway information.

4.5 Airport Identifier (ICAO code)

This is provided for future interoperability with GPS products which use the ICAO airport

identifier. At present the airport identifier is just displayed for your reference.
