Gunger - I can quite understand ltn's frustration as your post does not make sense to pilots! This bit
our company plan us to arrive in both varients with 2400kg over the destination!
is just plain illogical UNLESS you always have CMRs less than 16/1800kg or so - if so you should state that. At least ltn
claims to be just 'a pilot'! Your profile gives us no clues, so in order that we can sensibly address your question - state your type, seat and experience please plus the regulatory framework (eg EU OPS) under which you operate. Otherwise we are just going to dig up all those old bones of whingers about company fuel policies who basically have little or no idea about what being a 'Captain' is all about. In the UK, the ANO spells out the Captain's responibility for fuel planning and as ltn pointed out to you, YOUR
Ops Manual, Part A, Chapter 8. (Under EU OPS) should
/will re-state that requirement. Over to you?
To answer your last question, yes, although I have on occasion given
consideration to the option available under EU OPS for fuel planning.
Given the parameters for destination conditions you state in post #1, WHY would your PIC need to 'replan' the company plan just because it is a few hours old?
