Abstract: A compact altitude and rate of descent instrument is combined with a visual indication device and attached directly as a self-contained unit to protective eye wear or headgear for the determination of critical altitudes while engaged in freefall skydiving without the need for head or hand movements. Such an instrument reduces potentially fatal lack of altitude awareness due to extraneous factors and allows for more complete concentration on maintaining eye contact with others when performing maneuvers in close proximity such as during freefall formation flying (relative work).
