This collection brings together 15 primary-source technical documents covering all major variants (A, B, C) and the full spectrum of systems, armament, and operational equipment, providing an authoritative archival reference for historians, researchers, and aviation enthusiasts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDefinitive Collection with Free Lifetime Updates:\u003c\/strong\u003e This is a living collection that we continuously expand and refine.

The prototype first flew in 1937, and early flight tests revealed poor handling characteristics that were subsequently corrected through the introduction of power-assisted control surfaces — a refinement that transformed the aircraft into a machine praised by crews for being \"easy to fly.\"\u003c\/p\u003e\n\u003cp\u003eThe He 115 was an all-metal, mid-wing monoplane with an oval-section fuselage and twin floats constructed of \"hydronalium,\" a corrosion-resistant aluminium-magnesium alloy, supported by struts mounted below the engine nacelles. It utilized the NACA 2221 root airfoil and was powered by two BMW 132K nine-cylinder air-cooled radial engines producing approximately 960 PS (950 hp \/ 710 kW) each, driving 3-bladed variable-pitch propellers.\u003c\/p\u003e\n\u003cp\u003eThe He 115 outperformed its main competitor, the Blohm \u0026amp; Voss Ha 140, in stability and low-speed handling, and proved exceptionally robust in Arctic operations — its air-cooled radials being far less susceptible to combat damage than liquid-cooled alternatives. Variants included the A-series (export and early production), the B-series (enhanced range and payload), and the C-series (improved armament). The He 115 B-2 featured specialized ice skids for winter operations in Scandinavian and Arctic theatres. Norwegian and Swedish air forces also operated the type, and Norwegian He 115s famously continued operations against Germany after the fall of Norway.\u003c\/p\u003e\n\n\u003ch2\u003eManuals Included in This Collection\u003c\/h2\u003e\n\n\u003ch3\u003eVariant A \/ B \/ C — Aircraft Handbooks, Flight Manuals \u0026amp; Systems (3 Documents)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHe 115 A\/B\/C Aircraft Handbook\u003c\/strong\u003e — He 115-A,B,C Aircraft Handbook – Flugzeug-Handbuch (German Language)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHe 115 A\/B\/C Flight Manual\u003c\/strong\u003e — He 115 B\/C Flight Operating Instructions Manual, Bedienungsvorschrift Fl (German Language)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHe 115 A\/B\/C Systems\u003c\/strong\u003e — He 115 B-2 Aircraft Ice-Skid Floats Description, Operation and Testing, Beschreibung, Bedienung und Prüfung der Eiskufen-Schwimmer D.(Luft) T. 2115 B2\/Fl.
