Illustrative EVA Fixed Costs We estimate that the fixed costs associated with EVA operation will largely resemble helicopter / fixed wing costs, equating to -$600-$900 per hour assuming 1,000-1,500 hours flown per machine, per year (2) Category Assumption Annualized Per Hour Vs. Heli Aircraft Ownership / Lease Insurance Pilot Salaries (1) Pilot Training(1) Maintenance Tech Hangar Avionics/Subscriptions Parts Total 12% of $4mm aircraft value / year 3% of $4mm aircraft value / year $100k/year salary for two IFR-rated pilots $10k FlightSafety tuition 2x per year / pilot Partial use of salaried maintenance tech $2k per month hangar lease near Manhattan Monthly commercial avionics subscription $500 per month given limited moving parts $480,000 $480 120,000 120 200,000 200 40,000 40 55,000 55 24,000 24 14,000 14 6,000 6 $939,000 Per Hour, Assuming 1,000 Hours / Year Per Hour, Assuming 1,500 Hours / Year Source: Management estimates 1. 2. Additional pilots and training may be required to manage duty requirements depending on aircraft usage (i.e. hours flown per year) Management estimates of comparison to Bell 407 fixed costs BLADE These costs may decrease over time with large-scale manufacturing $939 ~1,000 hours per year is the $626 typical max useability for Part 135 rotorcraft 36 36
