High or low key points are points of reference used to 'assess' the approach. Flexibility is required during a FLWOP in order to ascertain how the approach is going in reality, and then to take any corrective action as necessary, including possibly making use of any 'alternative' landing area (if available), which should be part of the plan in the event of a FLWOP. Wind awareness is a very important factor, and should definitely be taken into account, especially when turning base or final. Procedures taught for action in the event of a FLWOP should be used as a guide, but FLEXIBILITY in the face of changing circumstance is the key to a successful landing.
