Lower than standard takeoff mins

Been hearing different takes on this:

The Jepp says takeoff mins are 2400 rvr. You have ops specs that allow 600. Can you takeoff?

If there are takeoff mins published, then you gotta follow them. If there wasn't anything on the Jepp, then you could do the 600 rvr takeoff, assuming it meets all of the requirements of your ops spec. Center-line lights, HIRL etc...

Depends entirely on what your specific Ops Specs and/or MSpecs say. They are controlling. Mine say that higher-than-standard mins on the chart must be followed, but for lower-than-standard, I'm given a table to work out my own takeoff mins.

So if the chart says 2400 for takeoff, that is controlling vs your ops specs that allow for 600?

Just to be clear, this is a runway requirement you are looking at, or one for a SID off that runway?

The ops specs are the same for any airline( C078 ). In order for you to use 600RVR (500 in Canada) there is certain equipment required. ie:HIRL, CL .... If the runway doesn't have all of this then the Jepp plate will say something higher like 1600RVR because there isn't any CL lights or HIRL.

You didn't mention if what are flying with how many engines. Standard minimums for two engines or less is 1 mile or 5000' rvr, under part 135. two engines or more is 1/2 mile or 2400' rvr. In my ops specs (c079) it specifies exactly under what conditions you can takeoff in less than standard, which for me is 1mile since I fly two engines. I can go as low as 600' rvr if I can meet the conditions under C079.

Under part 91 as I recall you can takeoff with zero if you are crazy enough to do it.

So what would one do if you HAVE two engines? Flip a quarter to pick which std mins to follow?

I didn't intend to provoke an obviously flippant response.

Part 135 prescribes takeoff minimums for transport category aircraft. If you have two engines or less it is ONE mile. You obviously know this. It is unusual for takeoff minimums to be listed less than standard on a chart but not knowing which airport was referred to, I don't know much more than what was originally posted. I'm always up to learning about something.

Again, since you are a super genius you already know that you can takeoff less than standard under 121 or 135 according to what your operations specifications allow or don't allow.

Part 91 operations require no takeoff minimums. You could flip a coin, as you are a known flippant already. You could evaluate and make a decision using a variety of means, I.e read tea leaves,wave a magic wand, throw a dart or whatever means you elect to use. I don't give a flip.

There is only ONE standard minimums under commercial operations.

Whoa, relax. You're the one who made the typo and said "two or less" AND "two or more". Read the bold part of the quote. I was being light and humorous.

Funny yes. Flippant no.

Two days go by and no apology or even an acknowledgement. Your original post had a typo and then you flew off the handle calling me out over nothing. And now crickets? Be a man and admit you overreacted.

My bet based on previous experience on this forum: You further attack me for god knows what reason. This forum is a breeding ground for simple minded angry posters. My challenge to you: prove me wrong.

Flying under Part 121, I figure lower than standard alternate minimums using a combination of the Mayan calender and the So-lunar tables!

You can only apply C-78 to standard take off mins of 1 SM for 2 eng airplanes and 1/2 SM for more than two eng. If anything is published that is different than standard T/O mins those apply. For instance a runway has T/O mins of 300' and 1 SM. Even though the 1 SM is std, the 300' ceiling is non-standard, therefore the T/O mins on that runway is one SM and 300' ceiling. In this case RVR 2400 in non-standard, it applies.
