![]() ![]() Military training routes labeled with four digits fly below an altitude of 1500 feet AGL, while those with three digits fly above the 1500 feet AGL boundary.įor our example, the IR146 and IR147 military training routes are flown above 1500 feet AGL. The more important aspects to consider are the direction of the training route and the numbers following the prefix. As far as drone pilots are concerned, this distinction is not that relevant. The only difference between the two is that IR routes are flown under air traffic control while VR routes are not. In sectional charts, military training routes are represented by arrows with labels that contain start with either an IR or VR prefix. The answer to this question is pretty simple, but this is a good chance to review the codes for military training routes (MTR). The numbers indicate the ground speed of the aircraft.The military training route is above 1500 feet AGL.The military training route is below 1500 feet AGL.What do the numbers on the labels indicate? While looking at a quadrant of a sectional chart, you notice military training routes labeled IR146 and IR147. Thus, the correct answer is 2100 feet in MSL units. This means that they need to have a common reference point, the most practical one being the altitude at sea level. Although the MEF figure in the sectional chart does not specify if it’s in AGL or MSL, all you need to know is that these readings need to be standardized across different quadrants of the sectional chart. The ‘21’ indicated as the MEF in our quadrant refers to an elevation 2100 feet.Īgain, the question throws another unit-related curveball by mixing up AGL and MSL readings. In our example, the MEF is indicated as a big 2 superscripted by 1.Īnswering this question is only a matter of understanding what the figures in sectional charts mean. Each quadrant of a sectional chart is labeled with the MEF in big, bold letters. One of the most important details to look for when you’re looking at section charts is the Maximum Elevation Figure (MEF). In the quadrant shown in the sectional chart, what is the minimum altitude that you must fly to avoid all the obstacles in the area? The estimated pressure at 3000 feet would then be 26.92” Hg. To solve the question, we simply need to calculate for the pressure drop for 3000 feet of altitude gain, which is 3” Hg. The standard lapse rate used in several industries including aviation is 1” Hg of pressure per 1000 feet of altitude change. While it doesn’t give accurate values, it’s still a useful tool in estimating atmospheric pressures in the absence of any pressure measurement tool. Since we know that pressure drops with increasing altitude, we can already eliminate options A and B.Ī standard lapse rate is a tool used to quickly estimate the standard pressure at any elevation. The question is asking for the pressure at 3000 feet elevation. First is the standard pressure at sea level, which is 29.92” Hg or 1 atm in metric units. To answer this question, you will need to know a few basic values to be used for the computation. Determine the standard pressure at 3000 feet MSL using standard lapse rates Since the ceiling is reported in AGL units, the maximum allowable limit for drone flight should also be expressed in AGL. The question also requires an understanding of the difference between above ground level (AGL) and mean sea level (MSL) units of altitude. If the skies are completely clear of clouds, the weather report will describe the ceiling as “unlimited.” This rule supersedes the 400-foot maximum altitude limit for drones in otherwise clear conditions. The FAA rules require that drone pilots maintain a buffer distance of 500 feet from the ceiling. In meteorology, the ceiling is defined as the base altitude of the lowest clouds reported relative to the ground. What is the maximum altitude that you are allowed to fly your drone? According to the weather report, the ceiling for today will be at 700 feet. We have compiled a list of the twelve questions that most test-takers have missed and attempt to answer them in the most detailed way possible. We’re here to help ease your worries a bit. If you’re still working towards earning your own drone license, then the prospect of taking the knowledge test may seem intimidating. Since it was first implemented in 2016, the FAA has now granted hundreds of thousands of drone pilots the privilege of flying their drones for profit. With such a thriving demand for drone-based services, the Part 107 drone license has become quite the commodity. The market for drone services has been growing steadily for the last couple of years and is expected to continue to grow well until 2025. ![]()
