Properties:
| Properties | Definition | Type |
|---|---|---|
| A | Usable up to a point on the ILS glide path measured along the extended runway centre line in the approach direction to a distance of 7.5km (4NM) from the threshold. |
enum value |
| T | Usable up to a point 4m (12ft) above the runway centre line and 900m (3000ft) from the threshold in the direction of the localizer. |
enum value |
| E | Usable up to a point at a specified height located above the intersection of the runway centre line and the threshold and through which the downward extended straight portion of the ILS glide path passes. |
enum value |
| D | Usable up to a point 4m (12ft) above the runway centre line and 600m (2000ft) from the stop end of the runway in the direction of the threshold. |
enum value |
| C | Usable up to a point through which the downward extended straight portion of the nominal ILS glide path passes at a height of 30m (100ft) above the horizontal plane containing the threshold. |
enum value |
