Althought the gauges showed 9,300 kgs the dripsticks showed 9,100 kgs!
- just a little confused by that, Bob - how did you arrive at '9,100kg' from a drip-stick reading? Presumably you used the actual SG, in which case why not just fill wings and ctre to the required
calculated kg base on ltrs? Were you actually filling
completely full?
BTW All airlines I have flown with use a check on lires/kg based on 'standard' SG (0.8) and this must be within 300kg (737). Where it differs from 300kg the actual SG is then used and if still >300kg a drip is performed
unless the discrepancy can be explained eg long-term APU usage. I have always found this adequate. I have achieved 9400kg in the wings with very cold fuel (KRK again).
