Quiz: 6 Questions To See How Much You Know About LPV Approaches

Boldmethod

Good luck!


  1. 1) You plan to fly the RNAV (GPS) RWY 17C into Dallas/Fort Worth on your personal Part 91 flight from Austin, Texas. You're about 25 minutes from Dallas, and you start listening to ATIS on 123.775. ATIS (almost an hour old) reports RVR 1200. Can you continue to Dallas?

    While operating under part 91, you can start the approach even though the required in flight visibility as specified by the LPV minimums haven't been met. You just need the required in flight visibility in order to descend below minimums. That being said, if the visibility is that low, you should be thinking about your diversion airport, and possibly not even attempting the approach.

  2. 2) The new ATIS is out, and the weather has improved. ATC is vectoring you for the approach and says "N231RT, descend and maintain 6,000', turn left heading 270. You can expect the RNAV RWY 17C." ATC vectors you on to the approach course 1NM after PENNY, but hasn't cleared you for the approach. At this point, you can descend to...

    ATC hasn't cleared you for the approach yet, so you need to maintain 6,000'.

  3. 3) ATC clears you for the approach, you've crossed ZINGG, and you're continuing the descent to JIFFY. What happens at JIFFY?

    At Jiffy, you'll intercept the glide path at 2,300' MSL.

  4. 4) When you reach JIFFY, how far are you from the runway?

    The GPS distance on the approach would read 5.3NM from the approach end of RWY 17C.

  6. 6) What approximate altitude will your altimeter show when you are crossing the runway threshold on glide path?

    The TCH (threshold crossing height) is 58' AGL, and the TDZE (touchdown zone elevation) is 562' MSL. By adding these two numbers together, you'll be able to figure out your altitude in feet MSL at the threshold.
