Field note 01
Your fleet average is hiding the tails that lose money
Regional Part 135 cargo carriers keep detailed records for the FAA, for their customers and for their accountants. None of those records tell you what each tail and each trip has to earn. ProEdge Flight Systems does, from the records you already keep.

One fleet number, two very different stories
If you run a regional cargo carrier, you know to the dollar how the fleet did last year. Revenue, fuel, payroll and net income all sit in the books. Now ask which aircraft covered their full cost, including their share of the certificate's overhead. For most operators, the answer turns into an estimate.
That gap matters because the fleet average is where losses hide. Consider the illustrative operator in our sample report: seven Cessna 208B Caravans flying $8.52 million of revenue a year. After every cost, overhead included, the fleet keeps $295,000, about three and a half cents of each revenue dollar.
That $295,000 is the sum of two very different groups. Four tails earn $585,000 between them. Three fly fewer hours than their fully loaded breakeven and give back $290,000.
Each group calls for a different decision. The strong tails show which contracts to protect at renewal. Each weak tail needs more hours, a better rate, a new base or a buyer. The same logic runs one level down: in slow weeks, one rotation in the sample misses its trip floor by $145 every time it flies. None of these calls can be made from a fleet average.
3 of 7 tails lose $290K after full cost
4 tails earn $585K between them. The fleet total shows $295K.

Every system you run answers to someone else
Regional cargo carriers are thoroughly digitized for compliance and barely digitized for economics. Your maintenance tracking answers to the FAA. Your booking and operations system answers to your customers. Your ledger answers to the tax authority, and payroll answers to your people.
Each of those systems does its job well. None was built to answer the owner's question. A tail's cost is spread across all of them: fuel and landing fees in the ledger, block hours in the flight records, engine time and work orders in maintenance, crew pay in payroll.
So the numbers get built by hand. Someone exports each of them into a spreadsheet, spreads the overhead by feel and produces a cost per hour that every quote and renewal then leans on. You can build that spreadsheet once. Keeping it reconciled every month, with allocations that hold up in front of a lender, is the part that breaks.
Where the money leaks
The money leaks in four predictable places. Each one is invisible in a fleet average and plain once every cost is tied to a tail and a trip.
Tails that never cover their fixed burden
Every tail carries a fixed burden before it flies: its financing, hull insurance and hangar, plus a share of salaried crew and the certificate's overhead. In the sample, the Hobbs aircraft carries $506,000 of fixed cost and earns $525 of contribution for every hour it flies. It must fly 964 hours a year to break even. It flew 1,040 and cleared its full cost by $40,000.
Three tails in the same fleet flew between 105 and 215 hours short of breakeven. They flew all year and still lost $290,000 between them.
Small fleets feel this most. The FAA requires a Director of Operations, a Chief Pilot and a Director of Maintenance whether you fly six aircraft or twenty. Every tail you add lowers the burden on the others, and every tail that sits idle raises it.
One rate card for every lane and direction
If you sell space by the pound, your rate card likely charges one rate in both directions of every lane. Many lanes run heavy one way and light the other. In the sample, a morning leg leaves 82 percent full and the evening return runs at 9 percent.
Charge one rate both ways and you get both legs wrong. The full outbound leg sells at $0.72 a pound against a floor of $0.78 once the light return is counted. Return freight costs about $0.11 a pound to carry, because the aircraft is flying home anyway. Any return rate above that floor adds margin, which turns empty space into something sales can sell.
Engine reserves left out of the rate
An engine overhaul is the largest maintenance event most turboprop operators face. Because the bill arrives years after the hours are flown, it is easy to leave out of the hourly rate. In the sample, a $449,000 overhaul quote over a 3,600 hour interval adds about $125 to every hour flown. A rate that leaves it out looks profitable right up to the shop visit.
Quotes and renewals priced on cost plus margin
When a quote goes out at cost per hour plus a margin, nobody can say whether it clears the trip's floor or its full cost. The gap between those two numbers is wide. The slow week rotation in the sample needs $2,090 to cover the cost of flying it and $3,655 to cover its full cost. It brings in $1,945.
Renewals carry the same risk at a larger scale, because the price you agree today sets the margin for the life of the contract.
What ProEdge Flight Systems does
You send exports of the flight, maintenance and financial records you already keep. ProEdge Flight Systems builds them into one record of what every tail and trip has to earn. You see tail breakeven, trip economics and price floors by lane and direction, and every figure traces back to its source.
Think of the systems you run today as the instruments on the panel. Each reads one parameter well. What has been missing is the flight director, the display that combines those readings into the attitude to fly. You still fly the airplane. You stop flying it on a fleet average.
Every number carries its evidence. Recorded figures come straight from a system of record. Allocated figures are shared costs assigned by a driver you can see and change, block hours unless you have a better one. Modeled figures are estimates that carry their assumption.
Recorded cost is reconciled to your ledger where it ties, and gaps are shown rather than filled with guesses. That is what lets the numbers stand up in front of a lender or a buyer. In the sample, 79 percent of cost is recorded at the tail today, and adding tail classes to the ledger moves the allocated share to recorded.
The record stays current. After each monthly close, tail and trip economics are rebuilt from fresh exports and reconciled again. Before a new quote or renewal goes out, it is tested against the floor and hurdle from the latest close. A quote that lands $145 under its floor gets flagged.

What changes, seat by seat
For the owner, the fleet stops being one number. You see which tails earn their keep and which do not. You can test a renewal, an added aircraft or a sale against real tail economics before you commit.
For finance, allocations stop living in a spreadsheet only one person understands. Every figure shows its source and method, and the record ties to the books after every close.
For operations, the schedule gets a price. You see which rotations clear their floor, which slow week flying should be consolidated and what the return legs could carry.
For maintenance, cost lands on the tail that incurred it. Engine and propeller reserves sit inside every floor, and days out of service sit next to the hours each tail had to fly.
For sales, every quote has a floor and a target. You know the lowest price each lane can carry in each direction, what return space is worth and when a customer's freight should bill by volume.
Why the gap is getting more expensive
Three pressures make flying on a fleet average costlier every year.
The first is compliance. Every Part 135 operator must declare compliance with the FAA's safety management system rule by May 28, 2027. That adds fixed overhead, and on a small fleet each tail carries a larger share of it.
The second is the customer. Contract flying is bid and renewed on thin margins. Walking into a renewal without a trip floor means negotiating without a walk away price.
The third is capital. Engine overhauls, fleet changes, refinancings and sales all turn on tail level economics that a lender or a buyer will accept. Numbers assembled the month before the meeting rarely survive diligence.
How it starts, and what it is not
Getting started does not require a software rollout. It begins with a short call about your fleet, your customers, how you price and the systems you use. We tell you whether the analysis will be useful before you send anything.
You then send read only exports of your financial, flight and maintenance records, along with fleet and contract terms. No logins, nothing installed. We build the economics from those records and reconcile them to your financial statements. Then we walk you and your finance and operations leads through the report, the source reconciliation and the method.
The diagnostic is a fixed fee set by fleet size, shared on the first call before any data moves. After that, the record is refreshed after each monthly close.
Tail and trip economics and the quote and renewal checks are available now. Pricing operating events such as grounded days and late departures is in development. So is tracking decisions to measured outcomes, and neither is part of the current offer.
It fits Part 135 cargo and mixed operators with recurring flying: contract cargo, scheduled freight or regular charter lanes. The typical fit is 4 to 25 aircraft with at least a year of records. If you fly one or two aircraft, a well kept spreadsheet may be all you need.
It is decision support only. Your systems stay the record and nothing is written back to them. You keep all operational control and airworthiness responsibility. A mutual NDA comes first, your data is used to deliver your analysis, and identifiable operator data is never sold or shared.
Request your analysis
Every operator knows what the fleet earned last year. The next renewal, the next aircraft and the next refinancing turn on a narrower question: what does each tail and each trip have to earn?
Request your analysis and we will tell you on the first call whether it will be useful for your operation. If you would rather look first, the sample report shows what yours would contain.
