FAF on an ILS approach?

[Carl_Spackler]

In 121, if you are outside the FAF, you may continue the approach if the vis drops below mins. You just can't continue past the FAF, or begin the final approach segment unless the vis is at or above mins.

Just because the vis is below mins, doesn't automatically mean that you have to go missed.

5 T's with an ILs/LOC approach??? What kind of dumba$$ intructor are you

5 Ts have to do with holding

Time (start your time)
Turn (turn to outbound heading)
Twist (twist the obs) that's Omni Bearing Selector dumba$$
Throttle (reduce to holding speed)
Talk (tell ATC your entering the hold)

Oh that's right...you "paid" someone on how to write your resume..I forgot your stupid and can't learn anything on your own...Good Luck...

dude nobody does 5 T's in the real world, thats flight school pass-your-IFR checkride crap

by the way, nice language on the forum

oh and I vote for G/S intercept

What if the G/S goes out b4 the FAF?

Kevdog,

I assume you're asking tongue in cheek, but of course if the glideslope fails, going missed and returning after briefing a localizer-only approach is a better choice. Or selecting a different approach after going missed.

However, for the purposes of legality, if there is no localizer, then the published FAF applies. GSIA is no longer an issue, as there's no glide slope to intercept. Therefore, the published non-precision FAF applies, as does all that has hereto been discussed.

If your getting the flag on the g/s or a g/s fail message.... then your not shooting a precision approach anymore. so your FAF will be the maltese cross b/c now your doing a loc approach.

Everything that Avbug sez on this subject is correct.

Just to beat a dead issue even further...

One must also look to see how far the glide slope "feather" goes out. There are many approaches where this "feather" can extend nearly 20 miles from the runway. The majority, however, extend only 4-6 miles from the runway.

Look at the ILS 22R into ORD http://204.108.4.16/d-tpp/0704/00166I22R.PDF

Here, the "feather" extends to FNUCH. If you were to intercept the glide slope at FNUCH at 7000ft, this would be the beginning of the Final Approach Segment. (FAF if you will)

Now, look at the ILS 27L ORD http://204.108.4.16/d-tpp/0704/00166IL27L.PDF

In this case, the "feather" extends only to WILLT. Intercepting the glide slope outside of WILLT does NOT constitute the beginning of the Final Approach Segment. (FAF again)

To put it all together, if the weather drops below on the 22R approach while you are outside of RIDGE, you may continue. On the 27L approach, the weather must be at or above your specified vis mins for that approach when you cross WILLT.

Hope this helps.

I must tell you all that this was revised again on 6/7/2007, and it is still confusing as all hell:

http://ecfr.gpoaccess.gov/cgi/t/tex...&view=text&node=14:2.0.1.4.23.4.11.13&idno=14

How do you know if you are an EOD or not?
In the 121 world this seemed to be cut-and-dried, but in the 135 world it seems like a terrible effort at a cut-and-paste.
