Chapter 5 Flashcards Preview

 Oil pressure should remain steady during steady state forward flight or in level hover. Momentary fluctuations in oil pressure may occur during transient maneuvers (i.e. hovering in gusty wind conditions), or when flying with pitch attitudes above +6 degrees. These types of oil pressure fluctuations are acceptable, even when oil pressure drops into the yellow range (_______). Oil pressure should remain steady and should be in the ___ to ___ psi range for the UH-60A+, and ___ to ___ psi range for the UH-60L.

If oil pressure is not steady during steady state forward flight or in a level hover, or if oil pressure is steady but under ___psi, make an entry on DA Form 2408-13-1. Sudden pressure drops (more than ___psi) without fluctuations require an entry on DA Form 2408-13-1.
