Hi just want to confirm that in level flight,

Maximum Lift/drag ratio speed (around 4 degree AoA) = Minimum total drag speed = Minimum thrust speed = Speed for best miles per gallon = Best glide speed = Maximum Still air Range.

Thank you in advance.

Sounds reasonable.

In level flight the amount of lift required is not negotiable - It must be equal to weight. It follows that if lift is fixed, the lift/drag ratio must be at a maximum when drag is at a minimum. When drag is at a minimum, the thrust required is also at a minimum since thrust must equal drag in straight and level flight. For conventional aerofoils, wind tunnel tests show that drag is at a minimum at one particular angle of attack (about 4° for most conventional aerofoils).

When discussing maximum range, it’s important to clarify the context—whether we’re talking about radio communication, optical visibility, or another field entirely. Factors such as terrain, atmospheric conditions, power output, and equipment sensitivity can dramatically affect the achievable distance. For example, line-of-sight systems might be limited by obstacles, while long-range radio can be influenced by frequency selection and propagation modes. Safety margins should also be considered, ensuring reliable operation under less-than-ideal conditions. In practice, the stated “maximum range” is often achieved only in perfect conditions, so real-world expectations should be adjusted accordingly to maintain dependable performance over time. shillong teer result

The original question was referring to range as the distance an aircraft can fly with a given quantity of fuel on board - basic Newtonian physics. Your reply seems to be referring to the range of a radio navigation aid-a very different concept.

The maximum range of a projectile is achieved when it's launched at an angle of 45 degrees with respect to the horizontal, assuming no air resistance. This is a funda What is the formula for monkey type maximum range? The maximum range occurs when the firing angle is 45 degrees. So set the firing angle to 45 degrees and substitute this angle into the projectile motion equations. Substitute zero into y (vertical motion), and then non-zero x (horizontal motion) is the maximum range.The maximum range (R) of a projectile, given a constant launch velocity (v) and neglecting air resistance, is achieved when the launch angle (θ) is 45 degrees. The formula for maximum range is:In projectile motion, a launch angle of 45 degrees maximizes the horizontal range of a projectile when air resistance is negligible. This occurs
