An approach to land on a contaminated runway requires a fully stabilised final approach and a firm (but not hard) touchdown within the prescribed touch down zone. If either is not achieved, a go around or rejected landing is appropriate. The challenges of achieving a successful contaminated runway landing are such that there should be no indecision in either case.

Touchdown vertical speed needs to be sufficient to break through the layer of contaminant and find at least some friction so that wheel rotation speeds can reach normal levels quickly. This is necessary so that they will exceed the minimum required to prevent operation of the anti skid system. A theoretical target for touchdown rate of descent might be considered to be in the range 2 - 3 feet per second/ 120 - 180 fpm. Once main gear touchdown has occurred, de-rotation should start and thrust reverser deployment should occur. Both actions will increase wheel loading, which will ensure the achievement and/or continuation of wheel rotational speeds sufficient to allow lift spoiler deployment and brake activation.
