Signs
From wiki.flightgear.org
Currently there are very few signs at the airports in FlightGear. KSFO has (see http://www.flightgear.org/forums/viewtopic.php?t=903) and also a few airports in the FlightGear NL scenery and the Caribbean are equiped with signs.

Explanation of signs
There are many types of signs on airfields. The information on the signs may also be painted on the airport pavement. The following examples are described as if you were on the taxiway or runway, looking at the sign.
Runway Signs
| Taxiway location sign: Indicates the taxiway you are on. | OBJECT_SIGN {@L}A |
| Holding position sign: Hold here. From your position on the taxiway at midfield, the threshold for Runway 15 is to your left and the threshold for Runway 33 is to your right. This sign is located next to the yellow holding position markings painted on the taxiway pavement. | OBJECT_SIGN {@R}15-33 |
| ILS critical area boundary sign: Seen when exiting the runway, this sign marks the boundary of the ILS critical area. When ILS approaches are in use, be sure your aircraft has passed beyond this sign before stopping on the taxiway. | OBJECT_SIGN {critical} |
| ILS holding position sign: ATC may hold you at this sign when the instrument landing system is being used at the airport. Aircraft taxiing beyond this point may interfere with the ILS signal to approaching aircraft. | OBJECT_SIGN {@R}ILS |
| Runway boundary sign: This sign faces the runway and is visible to pilots exiting the runway. Taxi past this sign (dash past the dashed lines) to be sure you are clear of the runway. | OBJECT_SIGN {safety} |
| Holding position sign for approach areas: Hold here unless cleared to cross. Taxiing past this sign may interfere with arriving or departing aircraft to Runway 15. | OBJECT_SIGN {@R}15-APCH |
Other Signs
| No entry sign: Do not enter this area. Aircraft are prohibited. This sign would be found at the entrance to a one-way taxiway or at the intersection of a road intended for vehicles. | OBJECT_SIGN {no-entry} |
| Inbound destination sign: The military installation is to your right. Other information signs are Cargo, Term (Terminal), Ramp, etc. | OBJECT_SIGN {@Y}MIL{@r} |
| Outbound destination sign to different runways: Runways 27 and 33 are to your right. | OBJECT_SIGN {@Y}27-33{@r} |

Sign types
These instructions specify sign types. They refer to the sign names in the FAA specification:
| L858-Y | @Y | "Direction, Destination, Boundary" sign (black on yellow) |
| L858-R | @R | "Mandatory Instruction" sign (white on red with black outline) |
| L858-L | @L | "Location" sign (yellow text and frame on black) |
| L858-B | @B | "Runway Distance Remaining" sign (white on black) |
These sign type specifiers are used to request FAA signs L858-Y, L858-R, L858-L and L858-B of unspecified size. It is up to the implementation to choose a default size. If the size is known, then a size digit is appended, which also refers to the FAA standard:
| Size 1 0.460 m | Size 2 0.610 m | Size 3 0.760 m | Size 4 1.220 m | Size 5 0.760 m | |
| L858-Y | @Y1 | @Y2 | @Y3 | ||
| L858-R | @R1 | @R2 | @R3 | ||
| L858-L | @L1 | @L2 | @L3 | ||
| L858-B | @B4 | @B5 |
Multi-Letter Glyph Names
| ^u | up arrow |
| @d | down arrow |
| @l | left arrow |
| @r | right arrow |
| @lu | left-up arrow |
| @ru | right-up arrow |
| @ld | left-down arrow |
| @rd | right-down arrow |
| r1 | roman numeral I |
| r2 | roman numeral II |
| r3 | roman numeral III |
| no-entry | no-entry sign (white circle with horizontal bar on red background) |
Note that diagonal arrows always have the right/left letter first, as is common in Cartesian coordinate systems. So it's ru (right up), not ur.
Examples
- {@Y,@l}S7{@L}B{@Y}S8{@ru}
- {@Y}MAX_SPAN_52M
- {@R,no-entry}
- {@L}V2{@R}06-24
