Aircraft icing is common in high altitudes and may occur suddenly. Icing impedes lift in helicopters and can prevent them from flying. However, these same icing conditions can still prevent attack helicopters from firing their weapons. Jungle operations are characterized by dense vegetation, high temperature, high humidity, and heavy rain. Army aviation significantly enhances combat operations in jungle areas.
Artillery fire can be difficult to observe and adjust.
Thick foliage and rugged terrain reduce the range of radio communications. Hot, humid tropical air decreases aircraft lift capabilities. Weather is subject to rapid and violent change. Problems with corrosion are intensified, thereby increasing demands on spare parts and maintenance. Aviation forces can operate effectively in desert environments.
