PENKO: What makes you think my points are constants?
a) sitting in the hold, as a commander, would you rather be assured of how much fuel you can actually count on or or would you just rather hope that the FOB is accurate.
b) are you not aware that bowser uplifts are affected by fuel gauge accuracy?
c) I assume you are aware that the computer flight plan that has been prepared for your flight has a ZFW using probably optimistic weights for the pax? Have you never wondered why few airlines actually weigh their passengers ? (apart from the logistical problems)
d) diversion routings and assumed levels - have you not experienced the flow rate reductions that London apply to the TMA whenever there is significant wx. This should give you an inkling as to what happens when there is a major disrupting event at either LHR or LGW.
The other poster was simply trying to get people to understand the RELATIVE cost saving versus the TOTAL REVENUE collected and pointing out what minimum fuel levels do to your risk levels.
