Chapter Summary Most emergency situations can be avoided through proper  maintenance and preflight planning. The following summarizes  emergency procedures when they are warranted. •  Emergency landings require careful thought to  evaluate wind and terrain for a successful outcome. •  Emergency descents may be required because of  weather, avoiding other aircraft, or aircraft fi re.  •  Corrective action for system malfunction depends on  the specific aircraft procedures. •  High winds and turbulence are less of a threat when  the WSC aircraft is a significant distance above the  ground. It is takeoff and especially landing where high  winds and turbulence become the biggest problem. Do  not takeoff, fly, or land when the winds and turbulence  exceed aircraft limitations or pilot capabilities. •  If the VFR pilot flies into IMC conditions, the pilot  should return to an area of known VFR conditions. •  The BPS should be used as a last option and only if  total loss of control with no chance of recovery, pilot  incapacitation, or engine failure over hostile terrain. 13-20
