What are the dimensions of a helicopter pad?

Type 1 – Clear and level touchdown pad measuring 30 feet by 30 feet; safety circle measuring 110 feet in diameter. Type 2 – Clear and level touchdown pad measuring 20 feet by 20 feet; safety circle measuring 90 feet in diameter.

What is the diameter of a helipad?

The ICAO SARPs classify the levels of protection needed for elevated helipads by dividing them into H categories according to the size of the helipad. H1 helipads are up to 15m in diameter, H2 up to 24m and H3 from 24m to 35m.

How much space do you need for a helicopter pad?

The FATO must be at least 1.5 times the overall length of the helicopter. The width of the safety area must be at least 0.33 times the rotor diameter, but not less than 20 ft. (6 m).

What is the diameter of a helipad on board a vessel?

A circle of some 10 m diameter is required for the aiming circle of a landing area suitable for the larger helicopters in normal marine use. The circle should accommodate with safety the landing gear of helicopters for which it is intended and should therefore, if possible, be completely obstruction-free.

How big is a helicopter landing zone?

100-by-100-foot
The ideal landing zone is a level, 100-by-100-foot or larger area of grass or hard surface. Most civilian medevac helicopters in use today have a main rotor diameter of 35-50 feet and a fuselage length with main rotor blades turning of 40-50 feet. U.S. military helicopters are much larger.

What does the H on a helipad stand for?

The ‘H’ is intended to point to the preferred landing direction, with the two landing rails of the helicopter placed in the same formation as the H-pattern. In other cases, the ‘H’ may have been intentionally aligned to designate magnetic or true north.

What are the minimum dimensions a helicopter landing zone should be?

100 feet x 100 feet
Preparing the Landing Zone (LZ) The following guidelines must be utilized to select, prepare and secure a safe landing site for MedFlight: Size: At least 100 feet x 100 feet. Shape: Square, circular, or rectangular. Slope: Relatively flat (less than 10º slope)

What is the maximum slope for the surface of a helicopter landing zone?

7 degrees
d. Ground Slope. The ground should be relatively level and the slope should not exceed 7 degrees if the helicopter is to land safely (Figure 4-2).

What is the maximum slope for a helicopter landing zone?

As the collective is lowered, continue to move the cyclic toward the slope to maintain a fixed position (frame 3) The slope must be shallow enough to hold the helicopter against it with the cyclic during the entire landing. A slope of 5° is recommended maximum for training in most helicopters.
