What do MSA and MEA stand for, and what do they ensure?

Explanation:
MSA and MEA are minimum altitude values used on enroute charts to ensure safety along flight paths. Minimum Safe Altitude is the lowest altitude shown that provides obstacle clearance within a defined area around a navigation aid (typically around a VOR or airport). This means flying at or above this altitude within that area guarantees clearance from terrain and obstacles. Minimum Enroute Altitude is the lowest altitude between navigational fixes that guarantees both obstacle clearance and reliable reception of the navigation signal along the route. So, the statement that MSA ensures obstacle clearance around a VOR/airport and MEA ensures navigation signal coverage and obstacle clearance along a route is accurate.
