Aircraft Operational Status decoding wrong fields

[mrksngl]

In class SurfaceOperatioanlStatusV1Msg

• method getGeometricVerticalAccuracy: there is no GVA (Geometric Vertical Accuracy) in the "... for Surface Participants (Subtype=1)" message. Rather, the class decodes a reserved field. The method should be removed.
• methodgetNICSupplementC: NIC supplement C was not defined in V1, so it cannot be a member of the capability class. The method should be moved to SurfaceOperatioanlStatusV2Msg.
• method getSystemDesignAssurance: System Design Assurance (SDA) was (iirc!) not defined in V1. The method should be moved to SurfaceOperatioanlStatusV2Msg.

In class AirborneOperationalStatusV1Msg

• method getGeometricVerticalAccuracy: there is no GVA (Geometric Vertical Accuracy) in V1. The decoded field is called BAQ and is a quality indicator that was later superseded. The method should be moved to AirborneOperationalStatusV2Msg.
• btw: GVA=0 in V2 means "unknown or above 150m", which is not clear from the documentation
• method hasSingleAntenna: V1 (as did V0) sent the Single Antenna Flag in the Airborne Position Message. I'm unsure if V1 repeated that information in the Airborne Operational Status (don't have the standard at hand).
