Excel/XLS - using VNAV for NPA
Hi People
Could a kind soul talk me through what needs to be done to use VNAV for an NPA, either VOR or NDB?
Our aircraft uses a UNS 1 FMS.
Currently what I'm doing for say a VOR is using APPR mode to maintain a more accurate track than just NAV. Dialling down the MDA and selecting VS mode prior to descent point and then at descent down we go! Both pilots are then monitoring the ROD to conform with the DME check altitudes.
I have been told by our training captain that we can use VNAV/FMS mode (ie. purple screen) providing we have the raw data needle overlaid as back up. Apparently this way both pilots can be in FMS mode but obviously still monitor the required ROD.
Would like to try this next time we're in VMC on approach.
Many thanks.
