- This video will help you understand takeoff minimums for 14 CFR Part 121 operators including Ops Spec C078 and Jeppesen 10-9 charts. Please note that you must know your own operator's Ops Specs as they are NOT all the same! Note that all charts shown are NOT current and for EXAMPLE purposes ONLY!
Check out my other videos especially the one about Part 91 takeoff minimums and takeoff alternates for Part 121 air carriers.

Always remember that Laura, when you get right down to it, is just a pilot and a dispatcher. She is explaining facts from the source materials but may be incorrect or out of date. You should always follow your primary guidance (Aircraft manuals, government regulations, etc.) before listening to anything from this RUclips channel.

Laura, thanks so much for this video, as well as your other videos. My situation is quite unusual. I use to fly for a regional airlines flying a CRJ-700. Then about 16 years ago, I had a cardiac event and lost my medical. Now, all these years later, I'm trying to regain my 1st Class Medical and get back onto the flight deck. I'm hoping to get my Medical back by the end of September, so I'm now in the process of studying for airline interviews. This video was very helpful for me to re-learn and understand T.O. minimums and how to apply the 10-9 Jepp pages. Thanks so much, and I look forward to watching your other videos!
Hey, thanks for the kind words! I am excited for you to be on track to getting your medical back! That is wonderful to hear. It's inspiring that you did not give up! Enjoy the other videos, and I'd love to hear other topics that would be of help to you.
Did you get your medical back?
You do a super job in explaining this. I understand now. thank you for your videos.
Wonderful! I’m so glad it helped you understand.
This is a great video! Thank you for taking the time to explain this concept. It was very clear and easy to understand. Looking forward to watching more of your videos! :)
Awesome! I am so glad you enjoyed it! Please let me know if you have other topic suggestions that I have not covered.
Great content. Could you make a video about low vis approaches and its legal requirements? Thanks
Glad you enjoyed it! What exactly are you looking for - IFR minimums? I’m not very familiar with Cat II and Cat III having never done those types of approaches, unfortunately. I try to stick to stuff I understand!!
Hi Laura, thank you so much for the video, very clear and informative! I have one question: I understand that if on the 10-9A the minimum is lower than Ops spec, we are restricted by our Ops spec, but what if Ops spec allows a lower minimum than the chart? e.g. Ops spec allows 5/5/5 with certain lights operative, and on 10-9A, it says 6/6/6 with certain light. Can we take off if the condition is 5/5/5 with all lights working? Or we can never go lower than the chart? Thank you!
My understanding based on ops specs for various airlines is that you can NOT ever go below the chart. Example: KGGG does not have enough RVR sensors for anyone to use 5/5/5 or even 6/6/6. Most airlines have at least 6/6/6 in their ops specs, but at KGGG they cannot do it because of our limited runway lighting and RVR sensors. So they cannot go below what is on the chart for KGGG. I hope that helps!
Great explanation. I Just wonder what conditions they mean by Standard? To what conditions std apply? Is it about the pressure?
Standard refers to what the part 121 takeoff minimums are as listed in 91.175. Those are what the charts mean when they say "standard" because it is what the regulation says. Anyone with a deviation to the regulation approved by Ops Spec C078 is "non-standard" technically.
Hey, so I was looking at the RVR for 15:50 and it says 500 feet in the Jeppesen chart but 600 feet in the ops. Can I still legally fly? How does that work? How am i limited at 9:45?
Thank you for watching! Some companies have 600' as their lowest allowable RVR per ops specs. In that case, they are limited to 600 even IF the chart from Jeppesen says 500. The ops spec is limiting in that case. I don't fully understand the question about what I was talking about at 9:45 though. Can you clarify?
Hi! Can you give us an example how to know if we are legal to take off; step by step. Part 121 regs.
I will check out doing a video on that topic!
@@LauraLaster747did you make that video yet?
@@Ezel21love Sorry, not yet. End of semester is busy, so I have less time. Hopefully this summer! Thanks for patience.
@@Ezel21love It just dropped! (I hope it's somewhat close to what you were looking for...) ruclips.net/video/GEVTrLIBmBs/видео.html
You can't use reduced mins on 14 because it does not have the required lighting.
You can use down to "adequate visual reference" which is as low as 1/4 sm visibility. That is still reduced minimums off the "standard" 1 and 2 mile (depending on engines). You are correct that it does not have the extra lighting required for lower than 1/4 sm visibility. I did talk about this at about 14 minutes into the video.
@@LauraLaster747 Yes, I just noticed it in the earlier portion when you were reviewing the 10-9 page, the reasons why they were different. Sometimes pointing out the basic idea of why the difference exist helps to understand the subject. You can't reduce to lower because the lighting does not comply. You have good videos, just thought I would add the comment because it might helps someone else.
@@MatyasArby Yes! Thank you so much. My home airport (KGGG) is also like this because of the lighting (lack of) and only one RVR sensor.
