All Danish Merlins have an advanced NVG-compatible EFIS cockpit with six ruggedised flat panel, 6.3-by-6.3-inch active matrix liquid crystal displays (AMLCDs) instead of the cathode ray tube displays in the earlier variants. They also have a nose-mounted FLIR Systems Star SAFIRE II FLIR, a laser obstacle avoidance system and a Telephonics RDR-1600 multi-mode search and weather radar. The radar display can be presented on any of the cockpit IDUs. They are much more comprehensively equipped than the RAF's existing HC.Mk 3s, which look pretty austere by comparison.
I have not found any details of the Danish DASS fit.
