2022年9月14日 · What Is TLOF? Touch-down and Lift-Off (TLOF) is another critical area of a helipad. It’s a paved and load-bearing area where the helicopter takes off or lands. This section is also the center of the Primary Surface and is easily identifiable because of its “H” marking.

The TLOF is a load-bearing, generally paved area, normally centered in the FATO, on which the helicopter lands and / or takes off. The FATO is a defined area over which the pilot completes the final phase of the approach to a hover or a landing, and from which the pilot initiates take-off.

Vertiports are distinguished with the addition of a “VTL” marking on the touchdown and liftoff area (TLOF). See paragraph 4.0. Geometry: Laid the foundation for updating the landing area geometry, creating a subset of the controlling dimension (D) related to just the propulsion devices.

A heliport should include at least one Touchdown and Liftoff (TLOF) area centered in a Final Approach and Takeoff (FATO) area, a peripheral safety area and two or more approach and departure paths. The TLOF must be at least as long and wide as the rotor diameter of the largest helicopter to use the heliport.

2023年1月5日 · This version adds guidance for pavement or structure larger than the touchdown and liftoff area (TLOF), but less than the size of the final approach and take off (FATO); turbulence effects; clearance between parking areas and taxi routes and within parking areas; minimum dimensions of curved approach/departure airspace; Touchdown/Positioning ...

The TLOF of a transport heliport is normally at ground level but may be developed with the TLOF located on a pier or, when carefully planned, on the roof of a building. The TLOF is centered on the major axis of the final approach and takeoff area (FATO). TLOF Size. Minimum Dimension.

A heliport should include at least one Touchdown and Liftoff (TLOF) area centered in a Final Approach and Takeoff (FATO) area, a peripheral safety area and two or more approach and depar-ture paths. The TLOF must be at least as long and wide as the rotor diameter of the largest helicop-ter to use the heliport.

Touchdown and Liftoff area (TLOF) is a load-bearing and paved area normally centered in FATO, on which a helicopter performs a touchdown or liftoff. The TLOF size is a function of helicopter type and rotor diameter (RD).

Touch-down and Lift-off Area (TLOF) at a Surface Level Heliport A defined area intended for touchdown and containment of the undercarriage.

For helicopters with a MTOM of 3175 kg or less, the TLOF should be of sufficient size to contain an area within which can be accommodated a circle of diameter of not less than 1 D of the largest helicopter the helideck is intended to serve.
