I can't say how common partial fuel loading in order to increase pax load is nowadays in the industry, but it is a great way to set up a fuel starvation event. Originally Posted by N9373M

If I were being pushed to do partial fuel loads to add a couple more pax, I would give the DZ two options, neither of which they are going to like-
1. Provide a calibrated fuel hock (dipper) certified in writing by a mechanic with gallon increments. You may be able to buy one already made somewhere. The mechanic will obviously charge to make one, because he will have to drain out all the fuel and refuel the airplane to calibrate the stick, which is a big chore.
2. De-fuel as necessary pound for pound in order to accommodate each added passenger over a normal pax load starting with a topped off fuel load. This is a bigger pain than getting a calibrated dipper made. No DZ in their right mind will go for it, but you should offer this option to show them you are serious about not having a fuel starvation event on your watch.
Using the fuel gauges or any other method is a gamble against the luck of the pilot. I discourage any new DZ pilot to gamble with the fuel load using home made dippers, fuel gauges, and guesswork. You'll really regret it if you have a fuel starvation event. It will haunt you for life as a pilot.

On the steep spiral question, you absolutely can unport the fuel taps doing steep spirals on the descent. You need to keep the fuel loads balanced left to right by alternating direction of turn on the hops. Do not get past your allowable load/ hop count, and I discourage playing with the fuel selector to balance tanks because you will forget to select it to "both" sooner or later. The gauges are not trustworthy on old 182s either, so do not use that to do it.
