METTC
What does MET-TC stand for

What additional tactical considerations are used to estimate the tactical situation
Location of the objective from the HLS
Size of the element being moved
What are technical considerations and who’s responsibility are they
The considerations that pertain to the technical aspect of operation a day or night HLS
Responsibility of the pathfinder
What are the seven technical selection factors for an HLS
Size of HLP Landing formations Surface conditions Obstacles Approach and departure routes Atmospheric conditions Type of load
What factors dictate the size of the HLP and who decides them
Size/type of aircraft Pilot/unit proficiency Day or night operation Atmospheric conditions Decided by the aviation unit commander
What are the nine standard aircraft formations
Trail Staggered trail left Staggered trail right Echelon left Echelon right Heavy left Heavy right Diamond Vee
What is the most secure landing formation
Diamond is the most secure formation
Factors for HLZ consideration are grouped into what two categories
Tactical considerations
Technical considerations
What are acceptable surface conditions at the site
Firm enough to support weight of the A/C
Free of loose sand or snow or debris that cause brownout/whiteout conditions
What will a landing point never have
Obstacles
What constitutes an obstacle
18 in high wide or deep
Can ground slope be an obstacle?
Yes
When dealing with ground slope how should you land an A/C
Upslope or side slope. Never downslope
What slopes can any A/C land at
0-7 degrees
What A/C can’t land past 7-15 degrees
OH and UH A/C with skids must terminate at a hover
CH A/C must land upslope with an advisory
Can A/C land on slope past 15 degrees
No A/C can land past 15 degrees they must terminate at a hover
How is an ideal approach made
Long axis of the HLS
Over the lowest obstacle
Into the wind
How much buffer is given at ends of HLS
10:1 or 100m whichever is greater
How much of a buffer at each side of HLS
10M both sides
What is considered a headwind
Wind direction of 45 degrees left or right of land heading
Who can give permission to reduce buffer zones and by how much
The Ground Unit Commander and 5:1 or 50M
How much can side buffers of the HLS be reduced
They can’t be reduced
