Confined Areas/DVE

Question 1

Explain the CA reccie profile:

Answer 1

• 60-80KIAS
• 300-500ft AGL

Question 2

Provide an example of the abbreviated CA approach plan:

Answer 2

Power: Cat 4
Wind: From the NW 5-10kts
Plan: Normal angle approach to the hover, terminating in the last 3rd of the pad, aborts to 12 o’clock, questions?

Question 3

What does LDP mean?

Answer 3

Landing decision point

Question 4

What are the three types of CA approach?

Answer 4

IGE, Profile and OGE

Question 5

When moving with a CA, how should pilot clear the area and how much clearance do they need?

Answer 5

Hover only in already clear areas, maintain 10ft seperation, if required make turns about the tail

Question 6

At what point on departure should a pilot call flyaway when departing from a CA?

Answer 6

10ft above obstacles and above F speed (preferred)
OR
5º point HMSD past end of pad

Question 7

What is different about the hover work cycle when departing an OGE pad?

Answer 7

Must remain lateral markers in case an abort is required

Question 8

How is flyaway calculated during an OGE departure?

Answer 8

Tree tops + HHP

Question 9

What are the three types of CA departures?

Answer 9

Standard departure
Profile
OGE

Question 10

Explain the profile departure:

Answer 10

• Pull max PWR (Hold up COL trim)
• Attitude as required to create a linear profile to decision point

DP = A point where F speed 10ft above obstacles is expected to be achieved

Question 11

Explain the CA profile approach:

Answer 11

Maintain F speed until past trees

Question 12

What perf cat is required for pins?

Answer 12

OPCAT 4 only

Question 13

What kind of approach is flown depending on wind speeds to a pinnacle?

Answer 13

Above 10kts = Steep/normal
Below 10kts = Shallow/level

Question 14

An offset approach is required for this pin, which wind direction is preferred, left or right?

Answer 14

Lift crosswind will reduce PWR to to less tail rotor authority req

Question 15

You are in the area and have had an engine fire and must land ASAP into the nearest CA, what is the sequence for the OEI to CA approach?

Answer 15

Setup: Downwind 300 to 500ft @ 75KIAS —> Brief plan —> Before LDG Cx —> Stores jet?
Finals: 300ft @50KIAS gate —> Normal to steep angle —> IAS above F speed —> INT PWR
Termination: Once “Committed” —> Maintain F speed —> Flare —> SUP PWR —> Zero/zero landing

Question 16

DVE can occur with what kinds of landing/operation environments?

Answer 16

• Ash/burn grass
• Snow
• Dust/dirt
• Water
• Heavy rain

Question 17

What restrictions are associated with DVE?

Answer 17

• Must be CAT 4
• Headwind is REQ
• Consid ASF, if any doubt, turn it on

Question 18

What types of approaches can be flown when DVE is expected?

Answer 18

Flared/flat at RLDG OR DVE approach

Question 19

Explain the sequence for the DVE approach:

Answer 19

50KTS —> Normal angle —> decel to F1 —> Committed —> Maintain above ETL —> Committed —> 20kts speed stable —> 20 ft flare —> Wheelie LDG

Question 20

Explain the sequence for a TAC departure?

Answer 20

30% PMI —> Wings level —> PMI to MCP, scanning donut & treetops —> @treetops: “rolling” —> @F speed: “flyaway”

Question 21

Provide an example PWP for a TAC departure?

Answer 21

P: CAT 4
W: On the nose 5-10kts
P: This will be a TAC departure to the 12o’clock, any PWR loss before rolling we will abort vertically down, after flyaway we will follow the low ground out towards the NE. Our flyaway speed 30kts, crew duties are standard, any Q’s?

Question 22

Explain the difference between “rolling”, “aborting” and “flyaway”:

Answer 22

Rolling =
Aborting =
Flyaway =
