lateral balance (aircraft stability). Balance around the longitudinal, or roll, axis of an aircraft.

lateral navigation (LNAV). A function of area navigation (RNAV) equipment which calculates, displays, and provides lateral guidance to a profile or path.

lateral offset moment (helicopter operation). The moment, in pound-inches (lb-in), of a force that tends to rotate a helicopter about its longitudinal axis. The lateral offset moment is the product of the weight of the object and its distance from butt line zero. Lateral offset moments that tend to rotate the aircraft clockwise are positive, and those that tend to rotate it counterclockwise are negative.

lateral precision performance with vertical guidance (LPV). A type of approach with vertical guidance (APV) based on WAAS, published on RNAV (GPS) approach charts. This procedure takes advantage of the precise lateral guidance available from WAAS. The minima is published as a decision altitude (DA).

lateral separation (air traffic control). The lateral spacing of aircraft at the same altitude by requiring operation on different routes or in different geographic locations.

lateral stability (aircraft stability). The stability of an airplane about its longitudinal axis, the axis passing through an airplane from nose to tail. If an airplane is disturbed from level flight so that one wing drops, lateral stability returns it to a level-flight attitude.

When a wing drops, the airplane begins to slip to that side, and the lift produced by the lowered wing increases. At the same time, the lift produced by the raised wing decreases. This uneven lift, caused by lateral stability, returns the airplane to level flight.
