The most comprehensive, highly recommended and recognized aviation checklists in the industry. You'll realize Checkmate checklists' incredible value the first time you use one. Many Endorsed Instructors of the Year, Best Flight Magazines and independent Aviation Safety Organizations have said: "Very comprehensive and practical. It's an invaluable contribution to aviation safety" - Rod Machado, Recorder, National Speaker, National Accident Prevention Advisor, Western Region Flight Instructor of the Year. With over 300 aircraft models to choose from, Checkmate will most likely have the model(s) you fly regularly and in the future. Checkmate offers 2 sizes of each single and twin engine aircraft model. All data is included on both sizes. It's a pilot's personal preference that matters. Checkmate checklists cover normal procedures and Vspeeds in the front and the more urgent emergency procedures in the rear. Also included on the back is a section displaying necessary information for: Weight and size, Fuel type and oil capacity, Balance capacity, Electrical, and Tire pressure. Trying to locate that much data on the internet can be very time consuming and let's face it, that much time isn't always what we need to fly an airplane.
