I have been looking for the answer to that very question. Excellent explanation! Every instrument student should watch this video. Thanks for taking time to demonstrate.
The APR button sequences the approach besides arming the LNAV & VNAV functions. It also loads the missed approach procedure.
This video has earned my subscription! I've been struggling with the use of this function and finally got it!
Glad it helped!
Thanks for helping me understanding the ‘APR” button.
The biggest reason I see pilots screw up APR mode in any of the Garmin avionics is when they aren't in a position to meet their altitude intercept. If your GS/GP intercept is 3,000 and you arrive at 4,000, the APR won't capture the descent. You really need that vertical diamond to be centered before it'll capture.
This is not true unless you are above GP/GS. It won’t capture from above. You need to come in and intercept from underneath the vertical guidance path. You can intercept at 4K but you have to be further back on the approach.
what a nice and clear explanation. THANK YOU
Finally. I have been searching for a good, simple, short explanation for when to smash the approach button. Thank you!
Glad it helped!
I searched the whole internet for the explanation, and then I saw your video. It helped a lot, thanks!!
Refreshingly well exlained. Thanks.
Glad it was helpful!
Horizontal very well explained. Thank you
As always great video !
Ur a great CFI I never understand it Ike that. Thx u
Thank you very much. Very helpful.
Yes! This is very helpful.
Great explanation! ARM 3D APPROACH
You just earned a subscriber!
I like your videos and your explanations. You do a great job. Love to see a closer shot of the pfd and mfd. can you zoom your lens in.
awesome explanation well done hello from Sydney Australia
Thank you, Sir! Glad you enjoyed it.
On top of arming GS or GP, I read somewhere that in APPR mode, the lateral sensitivity is increased as compared to Nav mode. In a 2D approach, could you shoot a VOR, LOC or LNAV approach by just pushing the NAV button and not use APPR? I thought the APPR mode was more ‘precise’ laterally than NAV. What do you think?
Pressing the APR Key arms both roll (Approach) and pitch (Glidepath/Glideslope) modes, to follow both the lateral and vertical guidance provided by the approach. But it will not follow the ARC on a DME approach.
Yes it will follow the DME Arc leg of an approach. If you activate an approach with the IAF set to the fix at the beginning of the arc. I just did it the other day in MSFS and I just confirmed in the G1000 NXi pilots guide page 364. Bottom of the page is a section on its use with a DME Arc.
Thanks for this video. If you want to intercept a 2D approach (VOR approach for example), is the APR mode able to capture only the lateral track? (even if NAV would be more adequate)
Yes. It will track whatever is available. Either 2D only, or 3D
Gilman is right-on. Additionally, an important question is: When do I press the APR button? You press the APR button after an approach has been loaded into flight plan. And, after Approach Control says, “N123 you are n miles from final approach fix, ‘CLEARED FOR THE APPROACH’”. This is known as a trigger, an event which cues the pilot to perform a specific action. When Pilot hears “… cleared for the approach”, pilot presses the APR button. It is a trigger response. The next question is: When can I set the MAP Altitude into the altitude alerter?
When both the localizer and glideslope have been captured
@@zmanfire9162 , When you hear, “Cleared for the approach. “
At the FAF when you capture the Glidepath , at that point the autopilot will disregard the altitude you dial in the altimeter
So when would you press VNAV button vs approach button?
VNAV is just vertical guidance. It follows the vertical guidance that's set at the fixes in your navigator. Once you have VNAV loaded in your navigator, approximately a minute from TOD, you'll hear "vertical track." At that point, you hit the VNAV button and it'll follow the altitudes down in your navigator.
