*NOTE: While talking about the LDA 19 Approach I mistakenly mentioned reduced ceiling requirements. I should have said that the MDA is lowered from 880ft to 480ft.*
The minima section of the instrument approach chart gives the pilot the complete set of descent minimums and visibility criteria for the procedure to be flown. The information provided includes all minimum altitudes for the approach, minimum visibility required to start the approach, heights above touchdown, and heights above the airport. Depending on the type of approach there can be many different minimums on just one chart. Some GPS approaches have 4 different sets of minimums depending on the capabilities of your GPS receiver. Some non-precision approaches have multiple minimums based on your ability to fix an intersection along the approach path.
Let's take a deeper look at all those numbers.
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
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 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
Hard to find information that explains these charts in detail. Thanks, I was needing this.
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
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.
The numbers in the parentheses are for military pilot, and "not applicable to civil pilots"
PLEASE REFERANCE THE TERMINAL PROCEDURES SUPPLEMENT!
@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...”
Very good presentation!!
Thank you for your support
Amazing video, I finally understand this part of the plate. Thanks!
Great explanation!
Thank you so much for these videos
Clear and precise explanation !
Great tutorial, clear speaking and very good visual explanation! Many thanks
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.
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.
Brilliantly succinct and valuable… thank you!
Awesome video, very informative! Also It feels like Mr. Rogers is explaining these approach plates.
Excellent teaching and video. Many thanks!
AWESOME !
Crucial Information !
Mainly Regarding Ceiling and Visibility Minimum !
Many Thanks !
Best Regards.

I really appreciate these quick lessons!
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.
Great video
Great video! You cleared a couple things up for me!
This is so calming
Fantastic refresher, thank you
AMAZING tutorials. Thanks for all the help!
In instrument training right now, good video!
THANKS FOR YOUR USEFUL INFORMATION. GREAT JOB
Thanks for the praise
Thanks Mr. Rogers
Slow and low. So easy to understand.
The best way for me to understand Thank you!!
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!
Great explanation thanks!!
Nice video but just one point of clarification.Under part 91 you can shoot an approach if visibility is less than the published minimum.
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)
if the reported visibility is NOT less than reported. As per 91.175 (c)(2)
thank you for this video, it greatly helped me
Awesome video man!
well done. thank you sir!!
These are great. Thank you.
Thanks for the feeback!
*GREAT lesson, had to put sped on 2x but perfect review before taking my IFR written exam tomorrow! thank you and happy MLK day!* :)
Love the voice, is it just me or do you hear a bit of Tine Belcher (Bob's Burgers) here?
extensive video. but where is the RA( radio alt)?
Cool. By the way awesome videos. Keep up the good work!
very good work
thank you
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.
Thank you very much sir
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
Thanks, could you also comment on horizontal limits for MEA, MOCA AND MORA ..
Seconded
Thank you
great video,however I may have to double check this video before attempt any ILS approach
So if doesn’t say MDH(A) in the S-ILS box, that first number is always the DH?
Excellent.
Thank you very much i benefited from it very much
but i don't understand LN AV-LVNAV-LPV when is GPS Approach used ?
TO DO THE BME APPROACH TYPE BME:ILS THEN TO LAND RUNWAY 10? THE COLON IS HOW YOU PICK UP TWO FREQUENCIES?
@ 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?
TO CHECK ALT MINIMUMS IN AAISA GOT TO AIRPORT DATA-AIRPORT DATA?
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?
THE THE SRS IS THE AIR TRAFFIC TRANSMITTER?
TO DO THE ILS APPROACH PLATE YOU TYPE ILS IF YOU TRUST THE LOC? THEN TO LAND RUNWAY 10? AFTER CLEARANCE?
Thanks!
when doing LNAV/VNAV, is the VNAV component always baro ? always GPS ?
(for Military Aviation Use)
THE BOXES ON THE COLOR AIRPORT DATA APROACH CHART IS THE ALTITUDE AND GLIDESCOPE.
It’s like the drone of the history teacher on the Wonder years. 💤
HOW YOU TYPE THE APPROACH IS DME:ILS.
That is wrong man what's in parentheses apples to military aircraft only
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
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.
HOW YOU DO THE NEXT APPROACH IS DME:GPS.
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
480 is thus a DA (not DH)
IN 2006 THE PRIVATE, OR PERSONAL, AIRCRAFT USED LORAN-C
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
thank yyou\
you keep referencing DH when its actually DA...
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.
DA/DH
Other then that it's a great video
THE LAST CLASS WAS PRA ILS
I MEAN LORAN C WORKS THROUGH ENR-RIGHT
BOY DREAMS, DREAMS
I WONDER WHICH CLASS I TOOK IN MY OTHER DEGREE?
WELL WHAT DO YOU CALL VOR? OMNI DIRECTION OF VOR(MON)? BOTH
again, nice "bite-sized" lesson
