The Flight Schools That Manage Fuel Burn Will Survive
Just like the 1970s oil crisis forced America to slow down, today's fuel costs demand that flight schools optimize every hour in the air. The operators who adapt will thrive. The ones who don't will price themselves out.

History Repeats at 3,000 Feet
In 1974, when OPEC quadrupled oil prices overnight, Congress enacted the National Maximum Speed Law: 55 MPH on every highway in America. The logic was simple — slowing down saves fuel, and saving fuel saves the economy.
Today, with avgas past $7/gallon and climbing toward $9+, flight schools face the same math. Cruising at 75% power when 55% will do is the aviation equivalent of driving 80 in a 55 zone — it burns significantly more fuel and costs you money on every single flight hour.
The difference? In training, you're not going anywhere fast anyway. Your students are doing maneuvers, practicing approaches, and flying patterns. That extra 15 knots at 75% power costs you $15-25 more per hour with almost zero training benefit.
A word on safety: We're talking about cruise segments only — the straight-and-level portions of a cross-country. You still climb at Vy (or Vx when you need it), fly the pattern at your school's standard speeds, and configure for approach per your POH. None of that changes. And at reduced power, keep an eye on your airspeed — especially at higher gross weights or density altitudes where you're closer to the back side of the power curve. Your POH is always the final word.
The Economics of Slowing Down
Just like the national 55 MPH limit, there is an optimal cruise power setting for every training fleet. Here's what changes when you find yours.
Lower Fuel Burn
Reducing from 75% to 55% power cuts fuel burn by 25-35% on most trainers. At $7/gal, that is $15-25/hr back in your pocket.
25-35%
Less Fuel
Lower CHTs, Happier Engine
Lower cruise power means lower cylinder head temperatures and reduced thermal stress. While TBO stays the same, cooler-running engines tend to have fewer in-service issues between overhauls.
Lower CHTs
Reduced Thermal Stress
Lower Wet Rates
Lower operating costs at optimized power mean you can offer competitive wet rates while maintaining healthy margins. Win the student, keep the profit.

Build This Into Your XC Flight Planning
When your students plan cross-country flights, have them use your school's optimized cruise power setting as the SOP. This teaches real-world fuel management from day one:
- 1.Plan cruise legs at the school's SOP power setting — use the actual TAS and fuel burn for that setting, not the POH's 75% default
- 2.Climb at Vy (or Vx when obstacle clearance requires it), fly pattern and approach speeds per your POH — the reduced cruise setting only applies to the en route portion
- 3.Account for gross weight and density altitude — a full-fuel, two-person 172 on a hot day has less performance margin than a solo flight in winter
- 4.Calculate fuel reserves using the actual consumption rate at your planned cruise power (30 minutes day VFR, 45 minutes night per 14 CFR 91.151)
On most training flights, the cruise segment is a fraction of the total time. The rest is takeoffs, climbs, maneuvers, pattern work, and approaches — all flown at POH-specified speeds. Talk to your CFI about your school's SOPs.
