May I ask, how many hours do your aircraft fly each year in your flight school?
I will try to answer more than you asked.
The aircraft flew 250 hours in the preceding 12 months and I flew an additional 75 hours in other people’s aircraft.
I gave about 400 hours of ground instruction counting briefing, debriefing for the missions, cross country planning, chart reading and weather briefings. Most of ground school is one on one and never more than four clients at a time for ground instruction.
I recommend King Schools for the knowledge test and then manage the difference for gyroplanes with ground instruction. I make a small commission on the King School package.
I charge by the hour an some take longer and some take less time.
I typically charge around $3,500 for an add on Sport Pilot Rating. Most of add on clients are high time pilots that have a lot to unlearn. Some take longer, some much less.
Sport Pilot rating for a primary student is typically around $7,500 not counting travel or the practical test. Most of my clients are north of 50 years old so they may be learning challenged.
If a primary student has their own two place aircraft I typically charge around $3,000 to prepare for the check ride.
Time spent on the enterprise is difficult to calculate exactly. A rough estimate would be about 1,450 hours in the last 12 months. A man year is 2,000 hours. I decided on a flight instructor renewal course and that took about 50 hours. The TSA refresher course takes about five hours and is every year. I spend a lot of time on paperwork for the FAA.
As I learn more and create training materials I suspect I will spend less time of lesson preparation.
The aircraft has been relatively trouble free other than typical oil changes, magneto service, sparkplugs, tires and brakes.
My 100 hours services have been averaging around $800 each and I have them done as annuals.
My clients have been hard on my helmet/headsets and I spent about $500 in the last year; I have three helmets/headsets so I am not down for headset repair.
I am building a reserve for the engine (Lycoming IO-320 $20,000) and rotor system ($12,000). The rest is just expensed out.
It is a one of a kind experimental so I don’t know when it will simply be worn out and will need replacing. A replacement aircraft will cost around $70,000 and may be more fragile.
