A) Money
The money to save when you are dropping is not only for fuel consumption, but price of time in flight in the logbook.

Which rules apply if the jumping center association is not the owner of the aircraft (which was the case in Belgium) ?

B) Technic
1. A quick climbing is learned during commercial pilot using best Vertical speed.

2. A level flight exists then where you can win 3 minutes or more if you are not on axis and have to come back.. : Untaught is the path to get around 10 seconds (point A) and not 3 minutes (point B) on axis before the dropping point. Two factors have to be managed :
2.1 Reaching the dropping level at the good position (point A) heading as mandated (mostly headwind) at the dropping speed with stabilized power.
2.2 Knowing where the dropping point is at the first flight when you have no clouds, climbing smokes, etc. only Met wind forecast. Every pilot has his technic to limit the level flight duration (see point 4)

3. The descent technic is only transmitted by rumors, the head of the Drop Center says very hypocriticaly "do as for yourself..." but starts the chronometer ! I mostly chosed to roll as soon the jumpers have leaved, avoiding them, and dive so much as possible. Someone - not me ! - are using the margin over VNE before constant deformation - twisted aircrafts exist!! -, or don't respect low level turbulence - not me -. The aircraft flies toward a short final near of the waiting next stick climbing quickly in the aircraft without stopping engine(s) and preparing and checking it for next take-off.

4. A mainlevel flight is often omitted (around 6 minutes) : The official and only technic taught to French professional parachutists (holding the validated DGAC license) uses two sickys.
You -the pilot - fly assumed headwind at the dropping altitude/height/level with stabilized dropping speed and power. You inform then the jumping instructor/leader you allow him dropping. At any moment you remain the captain of the flight, you respect the rules, and may stop the dropping.
The jumping instructor/leader (waering his chute) using the first sicky, oppens the door, puting and keeping the whole head outside in the wind and watching the altitude on his own altimeter, the landing point and the aircraft ground course and eventual drift, he asks eventual corrections left (turning left and right) or right (turning right and left) he throws firmly the first sticky passing exactly overhead the landing point without asking to "cut" the power, following the slowly descending sticky by the eyes until it is on the ground. Then the jumping leader estimates the drift distance of the sicky and report the distance from the landing point in the opposite direction to reckon the presumed dropping point. You the pilot did already a first 180° turn and are informed the assumed position of the dropping point, fly downind until abeam that point, continue 10+ seconds and do the second 180° turn (same sense).
The jumping instructor head outside on the door with the second sicky asks you eventual corrections and throws the "corrected sicky" overhead the reckoned drop point, follows it by eyes until the ground not far from the landing point, notices an ultimate correction translated to the dropping point.
You are now ready to drop your jumpers or freight.

C) Safety improvement
As about the sharing pedals technic (AA587), or fake documents, dangerous technics are used unsaid, and need better regulation.
