Looking at it slightly differently, at sea level the altimeter would read 1,900’ / FL019 if you set 1013 on it, so it is over-reading by 1,900’ relative to the actual height of the terrain; with 13,000’ indicated you’d actually be at 11,100’.
2) There’s not quite enough information given - it’s considered normal (legal) to plan to land with some fuel on board and that is included when you’re checking against MLM. Need to know a bit more about the different elements of the “fuel” as this could affect the maximum traffic load.
Yeah, it exists, but I’ve never heard of anyone actually using it...
1) Not really sure if I've got it down then. I'm not allowed to post links yet, but on pilotpracticeexams(dot)com(slash)altitude-calculator
example 3 where: alt. 2400 ft ; QNH 1011 (not looking to calculate density height, just want to focus on PH)
resulting PH is 2460 ft which would align with my calculation?
Could it be that I'm tripping over the fact that in my example it says flying at
FL130 instead of altitude 13.000ft on QNH?
2) yeah I guess a bit more info is required but that's all I have for now. But I've got a reference with all the weights so i'll look into it further, thanks anyway :-)
M&B will never catch on ...

not sure I'm following on this. Is it because off "mass and balance" instead of "weight and balance"?
Thanks
