Default Question of aborted landing after instrument approach

wrote:

ow this might have played out

if I had been on an instrument approach. Say I was on an ILS (HAF has
none, but pretend) at minimums, and I had to abort the landing after
the MAP. The weather is way below circling, so I need to get back up
again. It's too late to fly the missed. What can I safely do?

On the garden variety Cat 1 ILS you are at 200 feet AGL and over the
approach lights when you reach DH (decision height). How would it be
"too late" to fly the missed approach? If you are genuinely concerned,
pitch for VX instead of VY for any percieved obstacle clearance, but VY
should suffice nicely.



I mis-wrote in my first post, though most readers got my drift. I said
I was at minimums when I should have said that the weather was at
minimums (implying, for example, that circling back would be out) I was
talking about a scenario where I would be well below DH or past a MAP
when the runway incursion occurs.

As you point out, every instrument pilot knows you can initiate a
missed approach from DH or at the MAP. After all, most of us learned
how to fly approaches by repeatedly practicing that very scenario.


Also think about the practical aspects.. You went around because of a
runway incursion by an aircraft that didn't look before entering the
runway... had this been during a socked in IFR day, with a 200 or 300
foot ceiling, the vfr guys wouldnt even be turning a wheel.



I personally find this explanation somewhat unsatisfying. I (try to)
know the rules and operate by them but don't like my options to be
limited by what the "VFR guys" are //supposed// to be doing. I have
been flying long enough to see plenty of people depart VFR from
uncontrolled airports when they clearly should not have. Also, there
are the scenarios of the snowplow, animal, FOD, runway lights suddenly
going out, etc.

I'm satisfied with the answer found by the poster named Ray who found
the AIM section (5-4-21-g) that describes the procedure for going
around afer DH/MAP. They state quite clearly that the pilot should be
thinking "takeoff", not "missed."


That is not the message they are trying to convey. They are trying to
tell you that, where the airport/obstacle environment is that complex,
you had better well have a plan to avoid obstacle while getting back to
the published missed approach procedure.
