EASA ATPL062 radio-navigation foundations case studies
EASA ATPL062 radio-navigation foundations · Put your knowledge to work in context.
This independent study page provides practice for EASA ATPL062 radio-navigation foundations. Its editorial learning areas include Conventional aids, bearing and distance interpretation; GNSS, augmentation and PBN concepts; Propagation, radar and surveillance. The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. Topics on this exam: Conventional aids, bearing and distance interpretation, GNSS, augmentation and PBN concepts, and Propagation, radar and surveillance. The EASA ATPL062 radio-navigation foundations case studies are 4 cases and about 769 words.
1A slant range with an explicit vertical component
A fictional geometry exercise places an aircraft four nautical miles horizontally from a DME facility and three nautical miles vertically above it. These are actual geometric components supplied for the model, not a pressure-altitude reading that must be treated as exact height. Ignore terrain, signal errors and equipment delays for this calculation. A learner adds the two distances and reports seven nautical miles; another ignores the vertical component and reports four.

A fictional VOR interpretation exercise states that an aircraft lies exactly east of the station on its 090 radial. The reference is magnetic, there is no wind and the question asks for the straight inbound course to the station. The instrument is assumed serviceable and the geometry is explicitly ideal; no published arrival or obstacle-clearance procedure is supplied. One learner chooses 090 because it is the radial number, while another correctly distinguishes the bearing from the station from the inbound direction.

A fictional navigation-system display continues to show plausible coordinates while a separate status message says that the integrity-monitoring function required for the hypothetical task is unavailable. The exercise explicitly requires that function and provides no approved alternative sensor or operational exception. A learner dismisses the status message because the map symbol has not jumped. Another assumes that any working position display automatically grants permission for every instrument procedure.

A fictional radio worksheet specifies a propagation speed of 300 million metres per second. Its first part asks for wavelength at 150 megahertz. The second part gives a radar echo round-trip time of 20 microseconds, explicitly excluding processing delays, and asks for one-way target range. One learner uses the round-trip travel distance directly as range.
