Inheritance

This is a specialization of the string class and it inherits all attributes and associations of that class.

List of values

Name Data Type Definition  
A string 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.  
B string 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 1050m (3500ft) from the threshold.  
C string 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.  
D string 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.  
E string 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.  
T string Usable up to a point 4m (12ft) above the runway centre line and 900m (3000ft) from the threshold in the direction of the localizer.  
OTHER string Other.
