Generally, helipad are constructed with a PCC surface. The pavement is designed c.onsidering a

dynamic load bqual to 150 percent of the gross helicopter weight, equally distributed between the

main landing gears. For the majority of helicopters, which have a maximum gross weight less than

30,000 pounOr (13 610 kg), a 6-inch (150 mm) PCC slab will generally be sufficient. However, the

loads of fuel or maintenance vehicles pay be more demanding than the helicopter loads and may

require additional pavement thickness.

Since maximum gross weight of MI17 (Design Helicopter) is 13000Kg, which is less than 13610kg

so pCC slab of thickness oi tso mm should be provided over stone solittg of thickness 200mm oir the

portion of FATO. Compacted granular material of thickness 200mm should be provided on Safety

Area.

A. Helipad Identification Marking:

- Letter H, white color, dimension shall not be less than marking showing in Figure below.

- On a FATO which contains a TLOF, a heliport identif,rcation marking shall be located in the

FATO so the position of it coincides with the centre of the TLOF

- A helipad identification marking shdll be oriented with the cross arrn of the H at right angles

to the preferred final approach direction.

B. Touchdown and lift-off area perimeter marking

- A TLOF perimeter marking shall be displayed on a TLOF located in a FATO at a surface-

level heliport if the perimeter of the TLOF is not self-evident

' The TLOF perimeter marking shall be located along the edge of the TLOF'

- A TLOF perimeter marking shall consist of a continuous white line with a width of at least 30

crn.

A helipad shall be equipped with a wind direction indicator.A wind direction indicator shall be located so as to indicate the wind conditions over the

FATO and TLOF and in such i way as to be free from the effects of airflow disturbances

caused by nearby objects or rotor downwash. It shall be visible from a helicopter in flight, in a

hover or on the movement area.

A wind direction indicator shall be constructed so that it gives a clear indication of the

direction of the wind and a general indication of the wind speed.

An indicator should be a truncated cone made of lightweight fabric and should have the

following minimum dimensions for the Surface-level heliports. Length 2.4 m, Diameter

(larger end) 0.6 m, Diameter (smaller end) 0.3 m

The color of the wind direction indicator should be so selected as to make it clearly visible

and understandable from a height of at least 200 m (650 ft) above the heliport, having regard

to background. Where practicable, a single color, preferably white or orange, should be used.

Where a combination of two colors is required to give adequate conspicuity against changing

backgrounds, they should preferably be orange and white, red and white, or black and white,

and should be arranged in five alternate bands the first and last band being the darker color.

Touchdown and Lift-off area (TLOF): The TLOF shall be of sufficient size to contain a circle of

diameter of at least 0.83 D of the largest.helicopter the area is intended to serve.

For MI 17 Helicopter, the TLOF size is a circle of Diametet 2Im (0.83*25.31).

Final Approach and Take of Area (FATO): The dimensions of a FATO shall be not less than 1 D

of the largest helicopter when the maximum take-off mass (MTOM) of helicopters the FATO is

intended to serve is more than3,l75 kg and

0.83 D of the largest helicopter when the MTOM of helicopters the FATO is intended to serve is 3

175 kg or less.

For MI 17 Helicopter, size of FATO is 25.31 m*25.31m. For the design and construction the size is

taken as 26mx26m.

Safety Area: Fol Visual Meteorological Conditions (VMC), the safety area suffounding FATO shall

extend outwards from the periphery, at least 3m or 0.25 times overall length/width whichever is

greater and each external side of the safety area shall be at least 2 D where the FATO is quadrilateral;

for the longesVwidest helicopter the area is infended to serve (ICAO).

As, the FATO is quadrilateral the external side of the safety area should be 51m. As 26m FATO is

provided, hence, 12,5 mwide safety area is provided from the periphery of FATO.
