The P.11 had an open cockpit, provisioned with a windshield composed of Plexiglas. Instrumentation included a suite of navigation and engine control gauges, while many of these components originated within Poland, one notable exception was the German-built compass. The safety equipment included an arrangement of several flame dampers, a flare gun, and oxygen tanks for the pilot. Only a few P.11s were furnished with radio sets, leading to pilots being typically reliant upon hand signals and pre-arranged manoeuvres to communicate with one another.
