View-limiting device
aviation training device
In aviation training, a view-limiting device simulates instrument meteorological conditions (IMC) by restricting a pilot's field of view only to the flight instruments. They are worn by pilots who are working toward an instrument rating, which allows a pilot to fly under instrument flight rules in conditions that do not permit visual flight. They are also used by instrument-rated pilots while practicing instrument flight to maintain competency.
Examples include foggles and the IFR hood. Foggles are glasses that have been frosted on the top half of the lenses to simulate foggy conditions.
Use in training
View-limiting devices are widely used in instrument flight training to simulate the loss of outside visual references while still allowing a flight instructor to monitor the environment. In addition to traditional airplane instrument training, they are used in scenario-based helicopter training that recreates inadvertent flight into instrument meteorological conditions (IMC), including VFR into IMC scenarios. Safety campaigns and training syllabi recommend combining view-limiting devices with structured exercises and simulator sessions to teach pilots how quickly spatial disorientation can develop and to reinforce early avoidance and transition-to-instruments procedures. The U.S. Helicopter Safety Team (USHST) has promoted inadvertent-IMC awareness training and related safety resources for helicopter pilots, including the “56 Seconds to Live” campaign and guidance on simulator-based training.
The public source identifies “View-limiting device” as aviation training device. This brief keeps that definition visible, then builds a research path around View-limiting, device and aviation.
Why this record matters
A short description can identify a subject without explaining its stakes. For “View-limiting device”, the useful work is to connect “aviation training device” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q7928736. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
