That is correct. The minimums in parenthesis are there specifically for military pilots to derive their alternate information from. The numbers in parenthesis refer to AGL values so they can be an excellent source of additional information but are definitely not "true" minimums (even for the military guys).
Hi Will. You stated that DH for the ILS is the minimum altitude you can fly to for that approach. Was that a mixup? I always understood that MDA was a minimum height that cannot be broken until satisfied with visual requirements and that DA or DH was just a decision altitude. Am I mistaken in my understanding? Thanks
Thanks for finding that! I find myself flying mainly in the Part 121 world where that is the rule. I sometimes have a little crossover when I start talking rules and regulations. You are definitely correct that under part 91 you can fly the approach you just can't land unless you meet the requirements of 91.175
Thanks for the great video, minor comments: @2:25 you mention 480 as ‘minimum decision height’ however it is not a height it is an altitude called ‘DA’ (decision altitude) Also it is important to note the figures in parenthesis are for military use, not civilian use. Thanks for your work
"weather must be at or above the approach minimums" as viewed from the cockpit, not as reported by the ground. e.g The visibility in the tower is not necessarily the same as the visibility at the approach end of the runway-it could be better or worse.
I found in my instrument oral exam guide that any minimums found in parentheses are NA to civil pilots. Those minimums are directed at military pilots who should refer to appropriate regulations.
10:58 how is the “rounding” to the nearest hundred works? , in that plate it rounded less than what the HAT was, sometimes it round up or down, why is that
During the discussion of the different values presented in the IFR landing minima block, it was stated that the values in parenthesis after the barometric altitude (DH or MDA) and visibility necessary to initiate the approach are an Above Ground Level (AGL) height of the ceiling, rounded to the nearest 100 feet above the touchdown zone of the runway. This is incorrect. The values inside the parenthesis are "Ceiling in feet & Prevailing Visibility in SM" requirements for planning purposes, and/or required weather minimums (command regulation dependent) for Department of Defense (i.e., military) aircraft and DOES NOT apply to civilians flying the approach whatsoever. A full description of every symbol used on IFR plates are located at the front of the approach booklet if you'd like to verify this information for yourself. An excellent discussion on the approach minima block otherwise.
Thanks for the video. But can you please do one video specifically on RVR? I can’t find good clear explanation on the Internet. RVR and visibility, they are not exactly the same thing. RVR is horizontal visual range, not a slant range. How do you use the reported RVR exactly? Thank you!
I listened to the entire video because it has great information. But the voice was making me want to go to a nursing home and steal icecream from veterans.
@ 9:16 mark you say - "depending on whether 'you can fix' the GAUER intersection". I know what a fix is but what do you mean by 'you can fix'? Do you mean to say if I can add GAUER to the FMC? Can you elaborate?
You’re wrong about visibility at 3:40. You may conduct the approach if the reported visibility is less than reported. As per 91.175 (c)(2) “The flight visibility is not less than the visibility prescribed in the standard instrument approach being used;” and.. 1.1 Flight visibility means the average forward horizontal distance, from the cockpit of an aircraft in flight, at which prominent unlighted objects may be seen and identified by day and prominent lighted objects may be seen and identified by night. Visibility is also not the only limiting factor on whether you can land or not. It’s the acronym VAN from 91.175 (c)
You call the 480" for the S-ILS a "Decision Height", but I think it is a DA, decision altitude flown off your altimeter. Heights need a radio altimeter, like on CAT-II approaches.
In my King material it's referred to by both Decision Height and Decision Altitude - I think one is more current than the other, but they both reference the point on a precision approach where you decide to go missed or land.
+The Aviator the 24 means the RVR(runway visual range) value, and it is used to determinated the lowest visibility you are required to have on this type of approach. 24= 1/2 statue mile
I have a question, Always confuse with DA, DH .. which one is for which approach? And which one is AGL and MSL? I read somewhere that "Height" is always AGL. DA and DH are for Precision Approaches. But .. DA= MSL and DH = AGL? MDA is for Non-Precision App MSL? MDH is for Non-Precision App AGL? In the example of the video, can anyone write the data from any number? Like: S-ILS 480 (DA=MSL) 287 (HAT= AGL) ... something like that. Thanks
+Franjaver Ariza DA(decision altitude)= PRECISION APP AND IT IS BASED ON MSL, AND YOUR ALTIMETER. AND DH(decision height) IS USED IN PRECISION APP AS WELL. AND BASED ON HEIGHT ABOVE TDZ. AND YOUR RADIOALTIMETER. FOR MDA AND MDH APPLY THE SAME THE ONLY DIFFERENCE IS THAT THEY ARE USED IN NON-PRECISION APP. HOPE YOU GOT IT
When they survey the approach and create the procedure a complex system is used to determine minimums based on the obstacles in the area. It could be that some obstacle encroaches a little too close on one runway but is just outside the protected area for the other. This could be on the approach or missed approach as well.
The higher numbers for higher categories are not for "reaction times" but because of bigger turn radii and therefore different obstacle clearance requirements. See AIM Fig 5-4-30. Also the weather mins in parenthesis are for military only. You really shouldn't be producing these videos until you know the subject matter better.
By the way, I love the way he talk, slowly and clear, for foreign people studying here is perfect (like me).
Thanks for the videos!
I was thinking....His diction is Cat A 😂😎😉😄😆😎😆
Passed my instrument checkride! Your videos were very helpful and I've been recommending them to other students too! Thanks, Tony Fletcher

Hard to find information that explains these charts in detail. Thanks, I was needing this.

Thanks for your work
@3:40. Per part 91 you are allowed to start the approach, however the weather must be at or above the approach minimums to continue to land.
"weather must be at or above the approach minimums" as viewed from the cockpit, not as reported by the ground. e.g The visibility in the tower is not necessarily the same as the visibility at the approach end of the runway-it could be better or worse.
91.175 (c)(2) “...flight visibility...”
I found in my instrument oral exam guide that any minimums found in parentheses are NA to civil pilots. Those minimums are directed at military pilots who should refer to appropriate regulations.
Amazing video, I finally understand this part of the plate. Thanks!
Great tutorial, clear speaking and very good visual explanation! Many thanks
Thank you for your support
Awesome video, very informative! Also It feels like Mr. Rogers is explaining these approach plates.
Very good presentation!!
I really appreciate these quick lessons!
10:58 how is the “rounding” to the nearest hundred works? , in that plate it rounded less than what the HAT was, sometimes it round up or down, why is that
Clear and precise explanation !
Great video! You cleared a couple things up for me!
Nice video but just one point of clarification.Under part 91 you can shoot an approach if visibility is less than the published minimum.
Thank you so much for these videos
Excellent teaching and video. Many thanks!

Great explanation!
In instrument training right now, good video!
AWESOME !
Crucial Information !
Mainly Regarding Ceiling and Visibility Minimum !
Many Thanks !

there is mistake value in parentheses is DH/MDA and visibility for military aircraft not AGL height
This is military planning minimums.
Agree. He said 480 ft is the DH where actually this is the DA. The small numbers is the DH and in brackets the mil operations.
Awesome video man!
AMAZING tutorials. Thanks for all the help!
I listened to the entire video because it has great information. But the voice was making me want to go to a nursing home and steal icecream from veterans.
extensive video. but where is the RA( radio alt)?
@ 9:16 mark you say - "depending on whether 'you can fix' the GAUER intersection". I know what a fix is but what do you mean by 'you can fix'? Do you mean to say if I can add GAUER to the FMC? Can you elaborate?
Fantastic refresher, thank you
Cool. By the way awesome videos. Keep up the good work!
Thanks for the praise
TO DO THE BME APPROACH TYPE BME:ILS THEN TO LAND RUNWAY 10? THE COLON IS HOW YOU PICK UP TWO FREQUENCIES?
TO DO THE ILS APPROACH PLATE YOU TYPE ILS IF YOU TRUST THE LOC? THEN TO LAND RUNWAY 10? AFTER CLEARANCE?
*GREAT lesson, had to put sped on 2x but perfect review before taking my IFR written exam tomorrow! thank you and happy MLK day!* :)
Great video

THANKS FOR YOUR USEFUL INFORMATION. GREAT JOB
The numbers in the parentheses are for military pilot, and "not applicable to civil pilots"
PLEASE REFERANCE THE TERMINAL PROCEDURES SUPPLEMENT!
THE THE SRS IS THE AIR TRAFFIC TRANSMITTER?
im new at this, i fly the sim x-plane. ILS 10R approach, so i set the radio minimum to 287 for the minimum callout? and baro 480?
You call the 480" for the S-ILS a "Decision Height", but I think it is a DA, decision altitude flown off your altimeter. Heights need a radio altimeter, like on CAT-II approaches.
I agree, the 480 = DA
In my King material it's referred to by both Decision Height and Decision Altitude - I think one is more current than the other, but they both reference the point on a precision approach where you decide to go missed or land.
Thanks, could you also comment on horizontal limits for MEA, MOCA AND MORA ..
Seconded
So if doesn’t say MDH(A) in the S-ILS box, that first number is always the DH?
when doing LNAV/VNAV, is the VNAV component always baro ? always GPS ?
TO CHECK ALT MINIMUMS IN AAISA GOT TO AIRPORT DATA-AIRPORT DATA?
The best way for me to understand Thank you!!
Thank you very much i benefited from it very much
but i don't understand LN AV-LVNAV-LPV when is GPS Approach used ?
thank you for this video, it greatly helped me
5:58 What exactly does the 24 means?
+The Aviator the 24 means the RVR(runway visual range) value, and it is used to determinated the lowest visibility you are required to have on this type of approach. 24= 1/2 statue mile
These are great. Thank you.
Thanks Mr. Rogers
great video,however I may have to double check this video before attempt any ILS approach
Love the voice, is it just me or do you hear a bit of Tine Belcher (Bob's Burgers) here?
Great explanation thanks!!
so say i was on an approach. Would that 480 ft be above runway level, or above sea level (Radio or Barometer)
+Jazzar GK baro
Thanks for the feeback!
well done. thank you sir!!
I have a question, Always confuse with DA, DH ..
which one is for which approach?
And which one is AGL and MSL?
I read somewhere that "Height" is always AGL.
DA and DH are for Precision Approaches.
But .. DA= MSL and DH = AGL?
MDA is for Non-Precision App MSL?
MDH is for Non-Precision App AGL?
In the example of the video, can anyone write the data from any number? Like:
S-ILS 480 (DA=MSL) 287 (HAT= AGL) ...
something like that.
Thanks
+Franjaver Ariza DA(decision altitude)= PRECISION APP AND IT IS BASED ON MSL, AND YOUR ALTIMETER. AND DH(decision height) IS USED IN PRECISION APP AS WELL. AND BASED ON HEIGHT ABOVE TDZ. AND YOUR RADIOALTIMETER. FOR MDA AND MDH APPLY THE SAME THE ONLY DIFFERENCE IS THAT THEY ARE USED IN NON-PRECISION APP. HOPE YOU GOT IT
Slow and low. So easy to understand.
So why would Mc Carran's parallel runways have different viz minimums?
When they survey the approach and create the procedure a complex system is used to determine minimums based on the obstacles in the area. It could be that some obstacle encroaches a little too close on one runway but is just outside the protected area for the other. This could be on the approach or missed approach as well.
very good work
thank you
HOW YOU TYPE THE APPROACH IS DME:ILS.
Excellent.
HOW YOU DO THE NEXT APPROACH IS DME:GPS.
480 is thus a DA (not DH)
Thank you very much sir
Thank you
Thanks!
It’s like the drone of the history teacher on the Wonder years. 💤
That is wrong man what's in parentheses apples to military aircraft only
you keep referencing DH when its actually DA...
I WONDER WHICH CLASS I TOOK IN MY OTHER DEGREE?
(for Military Aviation Use)
WELL WHAT DO YOU CALL VOR? OMNI DIRECTION OF VOR(MON)? BOTH
THE BOXES ON THE COLOR AIRPORT DATA APROACH CHART IS THE ALTITUDE AND GLIDESCOPE.
thank yyou\
Other then that it's a great video
again, nice "bite-sized" lesson

IN 2006 THE PRIVATE, OR PERSONAL, AIRCRAFT USED LORAN-C
I MEAN LORAN C WORKS THROUGH ENR-RIGHT
