What is gumps aviation?

As an AI language model, I don't have access to current information. However, Gumps Aviation was a company that specialized in producing aviation checklists and related products. The name "GUMPS" originated from a popular aviation mnemonic that pilots use to ensure their aircraft is safe and operational before takeoff: "Gas, Undercarriage, Mixture, Propeller, Switches." The company was headquartered in Ohio, and their products were used by pilots around the world.
