AeroSpark ,
Monitored approach also has further benefits .....
The F/O flying the approach is usually younger , fitter , faster , better hand eye co-ordination than the ''crusty '' , old , grumpy , slower hand / eye / reaction skipper in the left hand seat [ I have been both ] . F/O on instruments and primed up ready for a go-around ... easy peasy , better than the ''old man '' performing one .
Skipper , as explained looking for visual clues [ takes about 5 seconds or so for older eyes to accomodate from distance vision [ outside ] to near vision [instruments ] . Therefore F/O already on instruments and ready to go upstairs . Skipper generally has more experience and rank to correct verbally or physically any poor flying by F/O . The other way around where a steep rank gradient exists might not be so effective [ Irish or Aussie F/Os excluded ! ]
Absolutely brill in poor wx , having done both .
