Ep. 217: RNAV Basics Explained Approach Plate

[@abbieamavi]

*the tip for pilot vs ATC controlled lighting at **6:13** was great, I'll remember that thank you!*

[@clr4tkoff1]

Jon - thanks for the videos; always very informative and help get the ball rolling on diving further into studying the mountains of aviation information required to safely and legally fly. Since I'm a bit late to this video, I was following along with a much newer IAP. I've always thought the same as you that the Amendment number/date is a good indication that nothing has changed. Turns out the new plate valid until 15 Apr 19 has the same date and amendment number, but things have changed. For example, the ODALS is gone and apparently that 839' tower grew a foot. So, I dug into the chart user guide to clarify. The date and Amdt at the bottom indicates "procedural/criteria revisions to the charted procedure, e.g., course, fix, altitude, minima, etc." However, the five-digit number at the top right above the "31" (16091 in your video) indicates the date of latest revision and is the Julian date the chart was last revised for any reason, e.g. a tower growing a foot. The current IAP shows 19059 up there, so it's a pretty recent revision for something on that chart. Thanks again!

How much did it cost to get one of those HUD eyes installed? Does it help when doing approach to minimums?

Yeah Josh I was wondering the same thing. Ole green eye CFI

[@fly8ma.comflighttraining199]

Yup, bionic eyes man....how else do CFI's see everything their students are doing even when they're not looking???

[@aviatortrucker6285]

I guess anybody who is under age 40 does not remember the original RNAV system. This was a system electronically by equipment would move a VOR station electronically to be in line so that you can fly a course without having to do the traditional zigzag VOR to VOR. It did this setting the VOR frequency, the radial where your course intercepted and the DME from the station. It would then electronically simulate that the VOR station was right on your course, and you just had to fly a CDI the way you fly the GPS CDI.

[@MrSuzuki1187]

You forgot to explain the LP, the first item on the approach minimums. It stands for Localizer Performance and references the higher accuracy of the the standard RNAV approach, which is found just below the LP. LP approaches generally have lower minimums.

[@michaelschwartz9485]

Great channel! I watch your videos on my phone, it would be nice if you could zoom in on the plates, they're almost impossible to read. Other than that, you do a great job!

[@storyofwill]

Great videos. Have you made the video on non standard take off and alternate like you said earlier in the video? Trying to locate it.. Thanks..

[@fly8ma.comflighttraining199]

Hey! the rest of the instrument videos are part of the IFR ground school on our site, www.fly8ma.com

[@aviatortrucker6198]

Hey I have a question concerning the procedure turn. If you are approaching the initial approach fix from the south and ATC clears you for the approach do you have to fly a procedure turn because you are approaching the fix which is directly ahead of you? I know with the airman information manual says but I thought that only applies to feeder fixes. It would seem senseless to make a course reversal when you are already practically on the inbound segment heading.

[@hunterfagan6272]

Im just confused about when exactly the missed approach point is when when the dashed lines are before the runway threshold for the rnav approach

[@messianichebrewshawnkawcak1550]

Probably the decision altitude Where you have to decide whether you go to a missed approach.

[@dhblan8591]

Dumb question from a flight sim newbie. Where does one get the approach plates?

[@bulamoves2987]

Hi Jon, is it mandatory to fly vertical guidance down to minimums or can you just drop down to mins after reaching faf?

[@alpenglow1235]

Why is the WAAS Channel Number and WAAS Reference Path provided on approach plates?

[@JohnDoe-yi9rm]

Talk about the box on the upper, left of the chart. WAAS. CH 78823.W31A....means?

[@floriniancau5766]

on the vertical plan of holding area missed 839ft antenna!!!

[@mybubu2000]

Thank you John

[@martj1189]

I dont want to offend you, is that normally how your eye looks, or was that a green screen effect?

[@Pilotalphapapa]

Joshua Martin all this wonderful information and that's question you ask smh

[@martj1189]

Because you kinda looked like the terminator

[@CatarineausArmory]

Why is my chart different and yet still same AMDT date????

[@usaviation2281]

Its a TCH of 40ft MSL correct?

[@38Flyer]

AGL, it's what your Radar Altimeter would indicate

[@AndTodaysProjectIs]

Hey John, Great Videos. Question on pilot understanding on "circle to land". At an uncontrolled airport, would you be automatically authorized to circle to land on this RNAV (GPS) RWY 31 to Venice without ATC authorization or does that need to be cleared with the controlling approach control or center in advance? Second question: If you are on a visual approach and for some reason you need to go around... We all know that unless there is a published go-around for a visual to a specific runway that there is NO go-around authorized. What does that mean for you as a pilot on an IFR flight plan to an uncontrolled airport? Obviously you could call the previous controller and cancel your IFR but what happens if you cannot do that? I have minimum IFR altitudes all over the place and when an aircraft is already airborne I'm having a hard time understanding how I can safely get you to where you are going from that point. Obviously if I give you a clearance from the ground using Victor airways that have Minimum altitudes .. you will depart the airport and figure out how to safely get to that airway as you climb to my MEA that I give you (on that route). My confusion is just the part if you give up the visual apch at say 3 mile final or something like that.

[@aviatortrevor]

Which simulator was featured at the end of the video?

[@VFRExplorer]

Looks like X-Plane 11

[@fred5727]

question: on the approach, are the hard crossing altitudes MSL or AGL before arriving at the MDA?

[@clr4tkoff1]

MSL. You'll find AGL altitudes in the minima portion of the plan view. Where you see "LP MDA... 360-1 344 (400-1)", the 360 is MSL and the 344 is AGL (360-Touchdown Zone Elevation (TDZE) = 360-16 = 344).

[@LEODECRISTO]

Really difficult to follow if you don't zoom in on sections of the chart during the video otherwise if could have been really informative

[@fly8ma.comflighttraining199]

Thanks for the feedback.

[@mikefromflorida8357]

Please show us the approach plate closer so we might actually see it. This doesn't help.

[@mrfofa09]

The runway designation (7:09) and approach course are different because the approach course is offset slightly. They don't need to repaint the runway designation. You're a CFII? You need to fix that.

[@clr4tkoff1]

Runway 31 is actually 320 magnetic course, so Jon is right here. Besides that, the inbound course line (thin arrow) pointing at the runway isn't offset by 10 degrees like you'd see on one that is truly offset. It takes quite a lot of effort, time, approval, etc. to change runway numbers, but they do it every once in awhile. Tyndall AFB renumbered a couple years back.

who noticed Jon's eyes have different colors 🤔

So I watched the entire video and I still don’t know what RNAV stands for. Risky Navigation maybe?? Just kidding. But seriously, if you’re doing a training video on RNAV, you might want to first explain what the term means.

[@Train_Bus_Plane]

Exactly... i dont know still what is a Rnav app and how to do it in action like simulator
