|
upperLimit | ValDistanceVerticalType
| Max altitude allowed for all aircraft categories at all defined speeds |
|
|
upperLimitReference | CodeVerticalReferenceType
| A code indicating the reference for a vertical distance.
Two series of values exist:
1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid
2) pressure distance. |

|
lowerLimit | ValDistanceVerticalType
| Minimum altitude allowed for all aircraft categories at all defined speeds |
|
|
lowerLimitReference | CodeVerticalReferenceType
| A code indicating the reference for a vertical distance.
Two series of values exist:
1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid
2) pressure distance. |
