KCRQ: ILS or LOC/DME RWY 24 – Visual Descent Point/Missed Approach Point

Asked by: 2867 views FAA Regulations, Instrument Rating


Where would be the Missed Approach Point for the Non-Precision Approach into KCRQ RWY 24?

The confusion stems from whether it would be at the VDP (I-CRQ 2.7DME) (since "typically this is a point on the final approach course of a non-precision approach, from which the aircraft would be able to continue its descent from the MDA to the runway threshold") - BUT one could always do a CIRCLING Approach. Therefore possibly could be the Runway Threshold (I-CRQ 0.9DME) - but the Profile View depicts the dashed missed line breaking off before then?

    The MAP for the localizer/DME approach is depicted with the vertical line at the threshold at 0.9 I-CRQ DME. With the AeroNav charts, they do not depict multiple pull ups for the missed approach as Jeppesen does on their charts, the just depict the one for the full ILS at the DA. The VDP only applies to the localizer procedure and is where the GS intersects the MDA. If you are at the MDA prior to the VDP, you should not commence your descent to the runway, assuming it is in sight, until reaching the VDP location.

    I agree with John except for one question I have:

    Assuming, on the localizer, you break out of the clouds before the VDP and have the runway in sight with plenty of visibility and visual references, maybe even a VASI or PAPI, why not begin a nice leisurely descent to the runway? I’ve always thought of the VDP as the last point from which one can make a 3° descent to the runway, the so-called “normal rate of descent using normal maneuvers” required by 91.175, not as the only point from which one should do so.

    Thank you @JohnDCollins for your clarification, for curiosity do you happen to have an image of the Jeppesen version of the KCRQ: ILS or LOC/DME RWY 24?

    Good question @MarkKolber!
