JOINT ADVANCED MULTI-ENGINE T-44A

Basics. Basically, the FLOLS appears as two sets of green (datum) lights arranged horizontally on

either side of a large yellow light (the meatball). When above the glide slope, the meatball will appear

to be above the green line formed by the datum lights. When below glide slope, the meatball will

appear below the datum lights. At the lowest limit of the FLOLS glide slope envelope, the meatball

turns red. The object is to line up the meatball with the datum lights. The five meatball lights are

framed by red waveoff lights. These will not normally be visible, but when activated by tower, they

will flash red and command a go-around. Other waveoff lighting that may be installed at USN/USMC

airports run along each side of the runway extending to 2500 feet from the threshold (see FIH section

B). All waveoff signals are mandatory unless the pilot is experiencing an emergency.

WARNING: When more than 0.75 () degrees above or below the glide slope, the meatball will disappear. When

in doubt, assume you are below the glide slope.

Missed Approach.

A. Planning.

Performing a missed approach successfully is the result of thorough planning. You should familiarize

yourself with the missed approach instructions during preflight planning. The missed approach

instruction is designed to return the aircraft to an altitude providing enroute obstruction clearance. In

some cases, the aircraft may be returned to the initial segment of the approach. A clearance for an
