These old aircraft require some TLC to correctly capture localisers and glideslopes.I think we get too used to flying FMC equipped aircraft and have to relearn radio navigation.I 've found it helps to use the drop down map to see where I am,to get back into the gentler handling required for approaches.My biggest challenge is watching those throttles to control the airspeed.Its easy to overshoot the capture or stall out.This aircraft needs constant hands on,i.e. real piloting,and thats part of the fun. :D :D :D
