The hilarious part is that we have a table for mechanical failures where you take a default distance and then apply a penalty based on what's broken. According to that table a 70,000lbs ice speed landing with a single break failure takes 4179'. According to our regular landing distance table a 70,000lbs ice speed landing requires 4930' under the same conditions.
In this situation the EYW runway wouldn't be long enough for a regular landing, but would apparently be long enough for a landing with a failed brake.
The inflight landing tables is the minimum distance required on a runway to accept a landing. It takes into account the land and stop distance, plus 40% (FAR requirement to land and stop within 60% of available runway). The unfactored landing distance tables are the actual land and stop distance..... unfactored for inop equipment, ect. So yes, you may be able to land and stop in less than 4930 feet, but the runway length required to ACCEPT a landing is the land and stop distance, plus 40%.
