Replacement DVOR Electronics at Kirkwall Airport

Descriptions

HIAL requires the capability to provide a DVOR service within the published DOC. User and technical system requirements will be defined in due course. The capability shall be delivered compliant to all applicable regulations, with minimal impact on Kirkwall Airport’s operations, by upgrading, replacing or adding to the core components of the current DVOR. HIAL believes it will be possible to re-use some, or all, of the existing infrastructure including the counterpoise, cabin, electrical systems and intersite connectivity, with the caveat that these are part of a system installed 30 years ago and will have aged accordingly. It is expected therefore that the successful technical solution will involve the replacement of the DVOR electronics and associated Remote Control and Monitoring System and the re-use or replacement of each of the existing cabin, counterpoise and DME. However, at this stage, HIAL welcomes suggestions for alternative approaches which may deliver better value. HIAL’s tender evaluation criteria will be weighted in favour of solutions which reduce cost and waste and minimise impact to the environment. It should be noted that the DVOR and DME antennas are to remain at the current coordinates to avoid any need for an airspace change proposal. It should be noted that, due to the impact on instrument approaches, ACP etc. the DVOR and DME antennas are to remain at the same current coordinates.
