Frequently asked questions
What costs should I include in my hourly operating cost?
The hourly operating cost should include all variable costs that scale with flight hours: fuel (the dominant component), engine reserves, proportional maintenance, landing and handling fees amortized per flight hour, and any per-flight crew expenses. Fixed costs (hangar, insurance, crew salaries) are excluded since they accrue whether or not the trip is flown. The defaults in this tool are variable-cost estimates by aircraft category.
Should I include positioning costs in the client quote?
It depends on your pricing model. Some operators charge the full trip cost (positioning + charter + return) in one quote. Others charge only for the revenue segment and absorb positioning. Either approach works, but the margin calculation must account for all hours actually flown. If positioning is included in the quote, input it as part of the charter price. If it is an operator cost only, leave it as a positioning hours input.
What gross margin is typical for Part 135 charter?
Gross margins on Part 135 charters vary widely by market, aircraft type, and operator structure, but operators typically target 20-35% on well-positioned trips. Trips with significant positioning overhead often run 10-20%. Anything below 10% is marginal and vulnerable to margin erosion from minor delays. Below-cost trips are sometimes accepted strategically (repositioning to a better market, client retention) but should be conscious decisions.
How do I use the break-even quote in pricing?
The break-even quote is the minimum total price that covers variable operating costs across all hours flown. Use it as a pricing floor in negotiations. Any quote above break-even contributes to fixed costs and profit. If a client insists on a price below break-even, the operator is subsidizing the trip from fixed-cost reserves -- acceptable occasionally but not as a pattern.
