The Advanced Aeromarine Sierra was an American high-wing, strut-braced, single-seat, glider that was designed and produced by Advanced Aeromarine, as a kit for amateur construction.

[1][2] The Sierra was intended as a lightweight and affordable glider with modest performance that could be launched by ultralight aircraft aerotow, auto-tow, winch-launch or bungee launch.

[1][2] Although very light, with a standard empty weight of 205 lb (93 kg), the Sierra did not qualify under the US FAR 103 Ultralight Vehicles regulations as a hang glider, neither was it foot-launchable.

[1][2] In September 2011 there were no Sierras registered with the US Federal Aviation Administration and it is likely that none exist anymore.
