How do you calculate GSE paint booth capacity?

Multiply units painted per cycle by available cycles to get gross capacity, then multiply by booth uptime and first-pass yield. With 2 jobs/cycle over 96 cycles at 88% uptime and 93% yield, gross is 192 and usable capacity is about 157 painted units.

Why is usable capacity lower than gross booth capacity?

Two losses bite into it: booth downtime for filter changes, cure faults, and maintenance, and finish rework on units that fail first-pass inspection. In the example those cost about 23 and roughly 12 units respectively, dropping 192 gross to 157 usable.

What is a good first-pass finish yield for GSE painting?

Mature GSE finishing lines running a consistent primer-and-topcoat schedule typically hit 92-96% first pass. The 93% default is realistic; below 88% you are losing more than a unit in ten to runs, sags, or dirt and should audit booth filtration and prep.

How do I increase usable painted GSE capacity?

Attack the larger loss first. If downtime exceeds rework, tighten preventive maintenance and filter schedules; if rework dominates, fix surface prep, flash times, and gun setup. Raising uptime from 88% to 93% in the example would add roughly 9 units.

Does this include prep and masking time?

No. A booth cycle should represent the full occupancy of the booth for one job, but bodywork, sanding, and masking usually happen off-line. If your cycle count only covers spray-and-cure, plan prep capacity separately or it becomes the real bottleneck.

Booth uptime vs first-pass yield, which matters more?

They multiply, so both compound. At the defaults uptime costs 23 units and rework costs about 12, so downtime is the bigger lever here, but a shop with reliable equipment and sloppy prep will see the opposite.

Airport Ground Support Equipment calculator

GSE Paint Booth Capacity Calculator

GSE paint booth capacity tells a ground support equipment shop how many tugs, belt loaders, and ground power units it can actually finish-paint in a given window once downtime and finish rework are stripped out. Production planners and finishing supervisors use it to commit ship dates on repaint and OEM build programs without over-promising the booth. It matters because the paint line is almost always the throughput bottleneck on a GSE refurbishment floor, and a single booth typically gates dozens of units a month. Quoting against gross booth math instead of usable capacity is how shops end up with half-painted tugs stacked outside the booth waiting on a rework slot.

What this calculator does

Estimate usable paint booth capacity for GSE frames, panels, stairs, loaders, tugs, and service vehicles from booth cycles, uptime, and finish yield.
a production planner needs to check whether paint booth capacity can support GSE build and delivery schedules
It computes how many GSE units a paint booth can actually finish per period after applying booth uptime and first-pass finish yield to the gross cycle count.

Formula used

Gross paint booth capacity = GSE paint jobs per booth cycle × available booth cycles
Usable painted GSE capacity = gross paint capacity × booth uptime × first-pass finish yield

Inputs explained

GSE units painted per booth cycle:
Available paint booth cycles in the period:
Paint booth uptime:
First-pass finish yield (no rework):

How to use the result

Use it when sizing a repaint backlog, committing delivery dates on a GSE refurbishment or OEM finish program, or deciding whether a second booth or shift is justified.
It assumes a steady mix of GSE units per cycle; oversized items like deicers or wide aircraft tractors consume more booth time per unit and will pull real throughput below the figure shown.
