Nope. Dual Nav before completion of solo circuit consolidation, PFLs, advanced turning and out-of-circuit solo PFL / advanced turning is too soon, one should plan a logical progression of dual, then solo, rather than inappropriate out of sequence dual instruction 'for something to do'.
After 2:15 solo circuits, 2:00 dual advanced turning and PFLs and 2:45 out-of-circuit solo, we did 1:00 nav intro, followed by a 1:30 dual trip dealing with operation at minimum level and/or in poor visibility culminating in precautionary landings. Then the Navigation and Radio Aids, Meteorology and Flight Performance and Planning exams.
By then the student would have flown a minimum of 20:00 dual and 5:00 solo. Only then would we start teaching triangular cross-country navigation exercises. Route 1 dual, Route 2 dual then Route 2 solo. Route 3 dual, Route 3 solo, then Route 4 as a dual progress check. Route 5 dual, then the student's first 'unseen' solo on Route 6.
