A variable area engine inlet (15) of a helicopter (10) is provided and includes first inlet portions (20) disposed to face one another in opposite directions and at a distance from one another and second inlet portions (21) extending between the first inlet portions (20) and being disposed to face one another in opposite directions and at a distance from one another. The first and second inlet portions (20, 21) define a capture area (150) and at least one or both of the first and second inlet portions (20, 21) include a movable portion disposed to occupy and move between first and second positions. The first position is associated with a non-constricted condition of the capture area (150) and the second position is associated with a constricted condition of the capture area (150).
