    Modern. Light.
    Sport.

    A members-only DFW flying club, anchored on a modern Jabiru fleet.

    120 knots true on 5 gallons an hour. Glass panel, autopilot, ADS-B. No equity buy-in, no oversubscribed schedule — just a modern airplane that's there when you want to fly.

    Modern. Light. Sport.

    Three words. One airplane.

    M

    Modern

    Glass panel. Autopilot. ADS-B In and Out. Synthetic vision capable. Built and equipped this decade — not refurbished from a panel that predates the iPhone.

    L

    Light

    Light Sport rules. 1,320 lbs gross. Sport pilot eligible. No third-class medical. No BasicMed paperwork. Driver's license medical is enough. You can fly tomorrow.

    S

    Sport

    120 knots true on 5 gallons an hour. Composite airframe. Honest handling. Built to actually be flown — short trips, frequent trips, fuel-conscious cross-countries.

    The Fuel Math

    Built for efficient flying.

    A dry rate is only as good as the fuel burn behind it. Our Jabiru fleet burns 5 GPH on ethanol-free auto fuel — leaving more room for the flying you actually want to do.

    A4 Aviation Jabiru
    5 GPH
    fuel burn
    $35 / hour fuel
    at $7/gal 100LL
    $3,500 / year
    fuel only, at 100 hours
    Piper Warrior (PA-28-161)
    9 GPH
    fuel burn
    $63 / hour fuel
    at $7/gal 100LL
    $6,300 / year
    fuel only, at 100 hours
    Cessna 172
    9.5 GPH
    fuel burn
    $67 / hour fuel
    at $7/gal 100LL
    $6,700 / year
    fuel only, at 100 hours

    Comparison assumes $7/gal 100LL across all three aircraft. These are fuel costs only. A4 Aviation's Jabiru rates are dry — you buy fuel directly, typically ~5 GPH (and cheaper still on approved ethanol-free auto fuel where available).

    Why Modern Matters

    Built for now. Not 1978.

    Pricing snapshot

    Monthly dues

    Caps roster size so the airplane is actually available.

    $100
    per month

    Founding member offer: first 10 members lock in $50/month for their entire first year.

    CFIs fly free — ask about our instructor program.

    Jabiru J250
    $110/hr dry
    Jabiru J230
    $125/hr dry

    10-hour block discount: Save 10% off the dry rate. J250 block = $99/hr · J230 block = $112.50/hr.

    Dry rates: you buy your own fuel. Aircraft are returned full. Members fuel directly and retain receipts.

    Why we price dry

    We switched to dry rates for transparency and control. Dry pricing separates aircraft time from fuel, so you pay the true cost of flying and capture the savings directly. Our Jabirus burn only ~5 GPH and are factory-approved for ethanol-free auto fuel, so your fuel bill stays among the lowest of any club fleet.

    What's included

    The things that usually cost extra.

    Fuel in your hands

    Dry rates separate aircraft time from fuel, so you pay the true cost and capture the savings directly. Our Jabirus burn ~5 GPH and accept ethanol-free auto fuel — your fuel bill stays among the lowest in the fleet.

    Online scheduling

    Flight Circle scheduling and billing — book from your phone, see live availability across the fleet.

    Proactive maintenance

    Rolling 100-hour and annual inspections tracked in-house. Squawks get fixed, not deferred.

    Glass-panel avionics

    Modern EFIS, ADS-B In/Out, autopilot-equipped airframes. No steam-gauge surprises.

    Insurance-friendly

    We work with your renter's policy and provide everything underwriters ask for.

    Real community

    Small, vetted membership. Group fly-outs, hangar talks, and CFIs who know your name.

    How A4 differs

    Built for frequent flying. Not just existing.

    Most flying clubs in the Metroplex run aging fleets, large rosters, and pricing models that hide the real cost of an hour. A4 is built differently.

    Aspect A4 Aviation Typical DFW club
    Aircraft age Built in the 2010s–2020s Typically 1970s–1980s
    Avionics Glass EFIS, ADS-B, autopilot Steam gauges, partial upgrades
    Fuel You control fuel cost (~5 GPH, auto-fuel approved) Often dry, fuel billed separately
    Equity buy-in None $5K–$25K+ typical
    Monthly dues Modest, capped membership Higher dues, oversubscribed fleets
    Scheduling Live online, capped ratio First-come, frequent conflicts
    Maintenance Proactive, in-house tracking Deferred squawks common
    Training focus Certificated pilots only Mixed primary training + rental

    Comparisons reflect general market norms across DFW-area clubs and FBO rental operations. Individual operators vary.

    Common questions

    Everything you'd ask on the intro call.

    Do I need to own any equity in the club?

    No. A4 is a members-only club with simple monthly dues plus a dry hourly rate. No buy-in, no shares, no exit fees.

    Is there a minimum hours commitment?

    No monthly minimum. Fly when you want. Block-hour packages are available if you'd like a discount for committing time up front.

    Do you offer primary flight training?

    No. A4 is for already-certificated pilots (Sport, Private, or higher). We do CFI checkouts in our airframes and recurrent / flight reviews for members.

    How far in advance can I book?

    Members can schedule out as far as the calendar allows in Flight Circle. We deliberately cap membership against fleet size so the airplane is actually there.

    What happens if an aircraft is down for maintenance?

    We notify members immediately, rebook affected flights, and prioritize getting it back online. Multiple airframes in the fleet means you usually still fly.

    Can I take an aircraft cross-country / overnight?

    Yes, with reasonable daily minimums on multi-day trips. Discuss the trip during the intro call so we can plan around the schedule.

    Ready when you are

    Join the club.

    We're accepting applications from certificated pilots in the DFW area who value modern equipment and a small, well-maintained fleet.

    Membership is subject to application, approval, and current fleet capacity.
