What would be your required pitch change at FL 300 and 60 DME to cross at 10 DME at 5000 ft, assuming speed stays the same?

To determine the required pitch change at FL 300 and 60 DME to cross at 10 DME at 5000 feet, you need to analyze the descent angle and calculate the pitch change necessary for the aircraft to reach the desired altitude of 5000 feet at the correct point.

At FL 300 (30,000 feet), you're starting at a significant altitude and you need to descend to 5000 feet, a total vertical distance of 25,000 feet. The distance remaining to the 10 DME mark is a crucial factor in this calculation. Given that you're at 60 DME and need to reach 10 DME, you have 50 DME to cover vertically.

Using a generalized rule of thumb for descents, it is often observed that for every 1000 feet of altitude to lose, an aircraft typically needs to cover around 3 miles horizontally. Therefore, for a 25,000-foot descent, you would generally need a descent angle of about 3 degrees. However, to account for the dynamics and necessary performance adjustments, particularly when considering the specifications of the T-1A Jayhawk's operational parameters, an average pitch change not only accommodates natural sink rates and aircraft performance but typically emphasizes a
