  1. My policy is to add 50% to what the book says assuming a "perfect" runway.
    Some planes (Arrow 180, Commanche 180, some Bonanzas and others) I start by adding 100%.
    Grass, longer grass, rough, gradient, wet, really wet, other oddities all add additional length requirement.
    To protect Vmc in a twin may require more.
    May seem overkill but it's better than the rose colored glasses used in the manual.
    Has worked for me. YMMV.
