FMS SID/STAR

rmaure06

Good morning,

I've been enjoying a lot the previews of you 146, and i have a few questions regarding the FMS.
First, will we be able to follows RNAV SID/STAR using it ? I know this airplane has been designed to fly using conventional navigation, but a lot of airports are changing their conventional departures and arrivals to RNAV only. I don't really care about RNAV/RNP approaches, but i'd love to be able to follow RNAV SID and STAR in the 146.

Best regards

Hi. There are many different types of RNAV equipment available to 146 operators. The most worst to use was the Trimble system (know as the ‘tremble’ to long suffering crews). Operators later standardised on various versions of the GNS system. All were capable of BRNAV, but ISTR only the GNS-XLS Enhanced was capable of being approved for RNAV procedures.

I not sure that the UNS version modelled for the JF146 was ever standard fit for the aircraft. I’ve used later version of the UNS (on corporate jets) that were capable of full RNAV including approach, but I don't think the early models were any more than BRNAV capable.

From a ‘Simming’ viewpoint, if the required SID/STAR is in the database, I would use it - but check that the various waypoints are correct first. btw, when using using RNAV routes/approaches/departures, other than removal as part of a routing, it is not permitted to amend or extra insert waypoints.
