Manually Operated Visual Landing Aid System (MOVLAS)
The MOVLAS is a backup visual landing aid system used when the primary optical system (FLOLS) is inoperable, stabilization limits are exceeded or unreliable (primarily due to extreme sea states causing a pitching deck), and for pilot/LSO training. The system is designed to present glideslope information in the same visual form presented by the FLOLS.
There are three installation modes aboard ship: STATION 1 is immediately in front of the FLOLS and utilizes the FLOLS waveoff, datum, and cut light displays. STATION 2 and 3 are independent of the FLOLS and are located on the flight deck port and starboard side respectively. MOVLAS is nothing more than a vertical series of orange lamps manually controlled by the LSO with a hand controller to simulate the ball.

“The United States is the only great nation whose government is operated without a budget. The fact is to be the more striking when it is considered that budgets and budget procedures are the outgrowth of democratic doctrines and have an important part in developing the modern constitutional rights.... The constitutional purpose of a budget is to make government responsive to public opinion and responsible for its acts.”
—William Howard Taft (1857–1930)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
“I foresee the time when the painter will paint that scene, no longer going to Rome for a subject; the poet will sing it; the historian record it; and, with the Landing of the Pilgrims and the Declaration of Independence, it will be the ornament of some future national gallery, when at least the present form of slavery shall be no more here. We shall then be at liberty to weep for Captain Brown. Then, and not till then, we will take our revenge.”
—Henry David Thoreau (1817–1862)
“Furniture! Thank God, I can sit and I can stand without the aid of a furniture warehouse.”
—Henry David Thoreau (1817–1862)
“A religion so cheerless, a philosophy so sorrowful, could never have succeeded with the masses of mankind if presented only as a system of metaphysics. Buddhism owed its success to its catholic spirit and its beautiful morality.”
—W. Winwood Reade (1838–1875)
