Ok my ignorance will be showing here, but a few guys have said fat on gas...why drag the gear around because of too much gas? To get down to max landing weight, couldn't you just ask for a lower altitude and let the engines do their thing and gulp down the fuel faster? Are there tire pressure monitors on the CRJ? I was thinking if they got a high reading maybe a tire got warm after a take off run? Stick it out in the breeze to see if it dropped back to normal? The biggest thing i have flown is a Duchess, so I have no idea.
