FRESNEL LENS OPTICAL LANDING SYSTEM (FLOLS)
Identify the function, color, and location of the FLOLS lights--source, cut, waveoff, and datum-- and
briefly explain the function of each.
1. The 5 source lights in the lens box indicate the aircrafts relative position on the glideslope (as
referenced to the datum lights). The top 4 lights are amber and the bottom light is red.
2. There are 4 green cut lights mounted horizontally on top of lens. The cutlights are used to indicate
Roger Ball, thereafter power. Utilized during Ziplip or EMCON at the ship (when radio calls are
not normally made).
3. There are 4 red waveoff lights mounted vertically on each side of the lens box. The waveoff lights
flash to indicate a mandatory waveoff command by the LSO.
4. There are 6 green datum lights mounted horizontally on each side of the center lens of the lens box.
The datum lights provide the reference for optimum glideslope and are used in conjunction with the
source lights in the lens box.
LANDING SIGNAL OFFICER
Give the corrective action (response) to each of the following calls and state whether it is informative,
advisory, or imperative.
Right for lineup
Easy with the power
1. Youre low: adjust glideslope immediately (informative call)
2. Right for lineup: come right to correct lineup to centerline (imperative call)
3. Easy with the power: reduce magnitude of power/attitude correction (advisory call)
FIELD CARRIER LANDING PRACTICE (FCLP)
Upon arriving at the 180-degree position, you find that you are too close. In order for you to arrive at
the correct 90-degree position, should you increase or decrease your AOB?
ANSWER: When you are too close at the 180-degree position, you will have to use maximum AOB to
arrive at the correct 90-degree position to prevent overshooting. In addition, you must increase your
initial rate of descent to be at the correct altitude at the 90-degree position.
