ATPL performance/loading

Quick question regarding the APLA exam.

AFT/Rob Avery seem to differ in their interpretation of the CAO's in regards to takeoff/landing performance charts. Ive read the CAO's but still a few things are a little confusing.

1. just to confirm- an EOL derivation for a takeoff chart will come from the shortest distance of ASDA, TODA or STODA (if shorter and < or = 1.9% gradient). Avery/AFT say in nil wind choose the longest runway for landing/takeoff (but the shortest LDA and or EOL?)

2. Wind is disregarded in taf calculations (forecast conditions), in AFT slope is disregarded too for both takeoff/landing charts, Avery provides a worst case scenario case for takeoff/landing where he corrects even TAF forecast conditions for a landing downslope or for a takeoff downslope- could anyone confirm either way?

3. if I am given a trip fuel which results in an exceedance of BRW/taxi out weight as Avery's text seems to allude to the possibility of in the exam (on the 727 load/trim sheet)- whats the best procedure to resolve a situation like this- given we cant reduce a given trip fuel load but could reduce the BRW (which would mean the only option is a payload reduction!)??

Cheers!
