Lift Off with the 2025 IRC MQF Test – Soar to New Heights and Ace Your Mission!

To determine the appropriate descent rate needed to arrive at JETOT at the published altitude while crossing AXENE at 3000 MSL, we first need to analyze the distance to the waypoint and the required altitude change. The descent rate calculation considers both the vertical distance to descend and the horizontal distance covered during that descent.

To arrive at the correct descent rate, you would typically use the formula:

\[

\text{Descent Rate (ft/min)} = \left( \frac{\text{Altitude Change (feet)}}{\text{Time (minutes)}} \right)

\]

In this scenario, if the required altitude at JETOT is lower than 3000 MSL, you would calculate the altitude difference and the time required to cover the distance to JETOT at an average ground speed. By applying the standard calculation of time based on the aircraft's ground speed, you can determine how many feet per minute you need to descend.

With the calculated parameters leading to a result of 833 feet per minute, this shows that maintaining such a descent rate effectively ensures proper altitude management over the specific distance until reaching JETOT.

In air navigation, it is crucial to adhere to these calculated descent rates to ensure safety and compliance with air traffic
