What are the seven technical aspects to consider while selecting an HLZ site? -
ANSWER 1. Size of HLP (Helicopter landing point)
2. Landing formations
3. Surface Conditions
4. Obstacles
5. Approach and Departure Routes
6. atmospheric conditions
7. Type of Load
What factors influence HLZ site selection? - ANSWER 1. Tactical
considerations (METT-TC)
2. Technical Considerations: Seven Selection Factors.
How is the size of the HLP determined? - The AVN unit CDR made its decision
based on:
-Air conditioner size and kind
-Pilot/unit proficiency
-Day or night
-The atmospheric conditions
,What are the typical airplane formations? - ANSWER 1. Trail
2. Staggered Trail Left (STL).
3. Staggered Trail: Right (STR)
4. Echelon Left (EL
5. Echelon Right (ER
6. Heavy Left (HL)
7. Heavy Right (HR).
8. Diamond - MOST SECURE
9. Vee
What is the distance between aeroplanes in flight? - ANSWER Day: 2 to 3 rotor
disks.
Night: 3 to 5 rotor disks.
What surface conditions are best for landing? - ANSWER Firm enough to
sustain the weight of the air conditioner, free of loose sand, snow, or debris
What can never contain an obstacle? - ANSWER A landing spot.
What is the definition of an obstacle? - ANSWER: Anything that is 18 inches
high, wide, or deep.
- Ground slope might be regarded an impediment.
, What do you do with obstacles? - ANSWER Four R's.
-Remove
-Reduce
-Red (Mark in RED)
-Radio (advise pilot)
In terms of slope, how do you land the aircraft? - NEVER on a downslope.
-Try to land on an upslope or side-slope.
What are the ground slope restrictions? - ANSWER: <7 degrees means any AC
can land.
>7 = AC with skids (OH & UH) must end at a hover.
For slopes <15, wheeled AC (with larger UH and CH) is recommended.
How do you compute slope and what is the round procedure? When is it
accurate? - SLOPE = (elevation difference / horizontal distance) x 57.3.
-Same units of measurement.
-- Always round up to the nearest entire number.
---Accurate under 20 degrees.
What is the land heading? / How do you wish to land? - ANSWER Approaches
are performed down the HLS's long axis, over the lowest barrier, and into the
wind.
