What is the diameter of the TDP for the AH-64, UH-60A/LM, and SH-60? - correct
answer 50 Meters (All 60 series A/C)
What is the diameter of the TDP for all CH A/C to include the MV/CV-22B (OSPREY)? -
correct answer 80 Meters (ALL CH A/C)
What is the diameter of the TDP for ALL slingload A/C (Daytime), A/C of unknown origin
(or unreported what is enroute to you), A/C in formation utilizing Land-Safe System? -
correct answer 100 Meters
What is the diameter of the TDP for all Slingload A/C using longlines? - correct answer
125 Meters
What is the diameter of the TDP for all Slingload A/C (Nighttime), A/C w/ Sling Load
utilizing Land-Safe System? - correct answer 150 Meters
What is the TDP? - correct answer Touch Down Point, the area you have cleared of
obstacles
Do Slingload A/C fly in formation? - correct answer No
, When referencing marking the TDP, what does the TDP distance and the crowsfoot
method tell you? - correct answer TDP tells how far to walk, and crowsfoot tells what
direction to walk
If establishing a TDP between the hours of 1800 and 0559, what must you do? - correct
answer Mark with light
What are the nine standard A/C formations? - correct answer Trail, staggered trail left,
staggered trail right, echelon left, echelon right, heavy left, heavy right, diamond (MOST
SECURE ON THE GROUND), and vee
Which A/C formation is the most secure on the ground? - correct answer The diamond
How is the TDP distance measured? - correct answer From center to center of the tdps
What is the distance between aircraft in flight during the day? - correct answer 2 to 3
rotor disks
What is the distance between aircraft in flight during night? - correct answer 3 to 5 rotor
disks
Which formation do you double the distance between the first and third A/C? - correct
answer Heavy left and heavy right
True or false. You will always clear the area for the ghost ship (in heavy left or heavy
right) but you do not mark it? - correct answer True
What is the formula to determine the needed usable length and width of the HLS?
(TRIANGLE) - correct answer SIN(45)xdistance
What is needed usable length and for 4 CH A/C flying in trail formation? - correct
answer 240 Meters
What are the ideal surface conditions for a HLS? - correct answer Firm enough to
support the weight of the aircraft and free of loose sand, snow, or debris
What is a way to determine the firmness of the HLS surface? - correct answer Alabama
boot stomp, heel cannot sink more than 2 inches
What are the Four "R"s of obstacles near the site? (anything that is 18 inches high,
wide, or deep) - correct answer Remove, Reduce, Red (mark in red), Radio (advise
pilot)
What is considered a surface obstacle in addition to the Four "R"s? - correct answer
Ground slope
