Here we go!
OK, you guys, here's my unpopular two cents. Normally, it is not a good thing to do an approach on the first lesson. But, sometimes, now I said "Some-times", in an experienced instructors best opinion, it can be of a benefit. He did say in a later post that he did lots of straight and level and turns climbs and descents. If that went exceptionally well,...well, maybe the ILS to finish off could be a good motivator. But that is a very individual decision of the individual instructor with the individual student under those unique conditions. See how I said that? I also emphasize the word "Experienced". The main point of that is to steer away from the "One Size Fits All" approach to flight training that we suffer under.
But the main reason I had to jump in here is that I ROUTINELY teach ILS approaches TO A LANDING UNDER THE HOOD. Yes, if you have been flying long enough, you have made an approach to near touchdown with very little runway environment contact. Life does not always go as planned. Just like we plan on engine failures and such. We should also plan on being forced to the ground in less than the required visibility. Would you make a missed approach into severe turbulance and lightning and green-black clouds. Is that a funnel cloud? Anyway, I would rather take my chances on following the localizer/glideslope to a known controlled crash to a runway than to climb up into a probable airplane break-up in the upcoming thunderstorm/tornado. And besides all that theroretical justification, it just plain builds skill and confidence to touchdown smoothly on the centerline in a landing attitude without ever seeing the runway. Cool, huh?
