New question regarding wet runway landing numbers. There are two ways of getting wet runway numbers for the Lear 45.
First, you have the standard part 135.385 (d) 115% of the dry runway number.
Second, you have the actual landing distances for wet runways chart, from the contaminated runway supplement.
Now, those two come out within 100 or 200 feet of each other for the most part.
BUT.
When you get into the fine print, the wet runway actual data considers MAX TR credit. The 115% rule, being based on the dry runway numbers, does not. If you use actual wet distance numbers, and then adjust for deferred TRs (as we have right now), and the basic part 135.385 (b) 60% rule, you need about a 7000’ runway for a max landing weight, calm wind landing. Using the 115% rule, you only need like 5500’ with the 60% factor.
Do you just go with the conservative number and say hey, we basically need a 7000’ runway right now? Do you go with the less conservative number because hey, it’s legal, and with that 60% rule you’ve still got a ton of wiggle room?
Just a guess, but is there hierarchical control in play here? Your AOM/Opspecs would be more conservative than 135.385, right?
I'm guessing. Do not know, but fascinated by this project of yours.
