Remote Operations

Question 1

What are three factors which affect aircraft performance?

Answer 1

Density altitude, aircraft weight, wind

Question 2

In high density altitude situations, what aerodynamic hazards may occur?

Answer 2

Greater chance for the development of retreating blade stall and vortex ring state

Question 3

How does density altitude affect the tail rotor?

Answer 3

Greater pitch will be required to generate the same force. I.e, more left pedal for all phases of flight

Question 4

In high density altitude situations, what happens to ETL?

Answer 4

It requires a higher forward velocity. You don’t gain it until later on take off, you lose it sooner on landing

Question 5

What happens to true airspeed at higher DA?

Answer 5

True airspeed becomes higher

Question 6

What are three landing site considerations?

Answer 6

Elevation, temperature, obstacles

Question 7

What are the three power numbers one must have before going into a remote?

Answer 7

Power available, power required, and power margin

Question 8

The “W” in WETPASTE stands for what?

Answer 8

Winds, Turbulence, and null areas

Question 9

The first “E” in WETPASTE stands for what?

Answer 9

Elevation of landing site

Question 10

The first “T” in WETPASTE stands for what?

Answer 10

Temperature and Pressure altitude

Question 11

The “P” in WETPASTE stands for what?

Answer 11

Power available, required, and margin

Question 12

The “A” in WETPASTE stands for what?

Answer 12

Approach/departure, obstacles, and go/no point

Question 13

The “S” in WETPASTE stands for what?

Answer 13

Suitability of site

Question 14

The second “T” in WETPASTE stands for what?

Answer 14

Touchdown point

Question 15

The “E” in WETPASTE stands for what?

Answer 15

Escape route

Question 16

What pattern is useable in an unconfined area?

Answer 16

Racetrack

Question 17

What patter is more useful in a confined area?

Answer 17

Circle or orbit

Question 18

What can occur at mountain tops which results in locally warmer temperatures?

Answer 18

The bubble effect on mountain tops. More likely in dense vegetation

Question 19

How does one calculate PA from site elevation?

Answer 19

Add 10 feet for every.01 inch the altimeter setting is below 29.92 or subject if above

Question 20

How does one calculate the PA of the site?

Answer 20

Subtracting radar altimeter number from barometric altimeter set to 29.92

Question 21

What is the minimum power that must be available to land at a remote?

Answer 21

5ft hover power

Question 22

When operating at a small RT (smaller than 2 rotor diameters) what is the required power available?

Answer 22

OGE hover power or greater

Question 23

What is the go/no go point for remotes?

Answer 23

The point at which maximum power available is insufficient to go around.

Question 24

Approach angle to an RT must be steep enough to allow for what?

Answer 24

Clear obstacles by 25’

Question 25

Steep approaches have what advantages?

Answer 25

Excellent visibility of the RT, more altitude to emergencies, enables landing at a smaller RT

Question 26

Steep approaches have what disadvantages?

Answer 26

Poor closure cues, more power required

Question 27

Shallow approaches have what advantages?

Answer 27

Better closure cues, less power required

Question 28

Shallow approaches have what disadvantages?

Answer 28

Requires a larger RT, poor visibility of the RT, less altitude for emergencies

Question 29

What is the 4-torque reference?

Answer 29

Charted, predicted, expended, actual

Question 30

Charted torque refers to?

Answer 30

What does the chart say you need

Question 31

Predicted torque refers to?

Answer 31

What do I need to add since the chart doesn’t account for everything. A “fudge factor”

Question 32

Expended torque refers to?

Answer 32

What was actually utilized for the manuever (Execute the maneuver and see what was actually used)

Question 33

Actual torque refers to what?

Answer 33

What is the real torque actually required for hover and takeoff
