In the "737 Performance Reference Handbook" the author makes a statement. And I quote:
The TOW on a wet runway must not exceed that permitted for a takeoff on a dry runway under the same circumstances. Therefor a Dry Check is required to exclude the theoretical possibility that, due to credits for reverse thrust and use of a reduced screen height, a higher TOW is obtained on a wet runway than on a dry runway, which is not allowed.
My questions are:
- What is the source of this underlined statement? (Boeing, regulatory etc.)
- Is this also applicable to an Improved Climb take-off?
