1. A pneumo-mechanical landing gear deployment system, comprising:
a dual-stage handle operatively connected to a pressurized tank;
a nose landing gear pneumatically connected to the pressurized tank; and
a main landing gear pneumatically connected to the pressurized tank,
wherein actuation of the dual-stage handle to a first position opens the pressurized tank thereby deploying the nose landing gear;
wherein actuation of the dual-stage handle to a second position causes further opening of the pressurized tank thereby deploying the main landing gear.
