King Air 200 Raisbeck Question

[General Brock]

This is one of those he said she said stories and I'm reaching out for some clarification.

King Air 200's with Raisbeck , does this change take off and landing speeds?

AFM says that Vr for a King Air I fly is 95 kts. When I look in the AFM in the raisbeck section, it says that it does not change anything in regards to the performance. Therefore I assume that Vr is still 95 kts.

However there are some more senior pilots I fly with, that believe there are different rotation speeds.

Raisbeck what? Props, leading edges, aft strakes, pitot cowls... There are a host of BE20 mods available.

As PostmasterGeneral said, which mods are installed?
If you have props, RARS, leading edges, dual strikes and high flotation gear doors then look at the take off charts for take with flaps at 40% in the performance section, there is a table which describes the relationship between Vr and weight. For take off with flaps up Vr is constant.
If not, the look for proper manual here:

If it's done up with most of the goodies and the "Quiet Turbofan" props, V1/Vr is 94. Big difference there Not sure about the sexy looking swept tip props.
There is a second set of numbers in the back of the Raisbeck Supplement for optimizing Accelerate-Go and Accelerate-Stop distances. V1 Vr and V2 are all in a big fancy table for aircraft weight, atmospheric pressure and temperature. They're more for operating 704, not 703.

All the Raisbeck supplements are available on their website, so if you have lots of free time, feel free to dig.

I think that's helpful. Thanks
