Sleep and neurobehavioral performance vary by work start time during non-traditional day shifts.

Introduction: It is established that shiftwork causes sleep loss and circadian misalignment. Individuals who work non-traditional day shifts that encroach into typical sleep times, such as those in the service and transportation sectors, may also experience sleep and circadian disruption. We aimed to determine how neurobehavioral performance and sleep would be affected by work start time among individuals working a non-traditional daytime shift pattern.

Simplified Approach Charts Improve Data Retrieval Performance.

The effectiveness of different instrument approach charts to deliver minimum visibility and altitude information during airport equipment outages was investigated. Eighteen pilots flew simulated instrument approaches in three conditions: (a) normal operations using a standard approach chart (), (b) equipment outage conditions using a standard approach chart (), and (c) equipment outage conditions using a prototype decluttered approach chart (). Errors and retrieval times in identifying minimum altitudes and visibilities were measured.
