If a cargo load has been exceeded, do you need to make a logbook entry?
Contact Dispatch and Maintenance - they will instruct is a logbook entry is required.
What is the approximate maximum total of the cargo bins?
-700 = approximately 4,300 lbs (fwd), 7,000 lbs (aft)

If an aircraft has a drag reduction kit, what is the minimum landing weight?
93,000 lbs. If landing at a weight of below 93,000 lbs, use this weight to calculate a Vref (may not use a Vref number lower than 93,000 lbs) – PWB will automatically adjust for a minimum of 93,000 lbs
