Remote Operations Flashcards
What are three factors which affect aircraft performance?
Density altitude, aircraft weight, wind
In high density altitude situations, what aerodynamic hazards may occur?
Greater chance for the development of retreating blade stall and vortex ring state
How does density altitude affect the tail rotor?
Greater pitch will be required to generate the same force. I.e, more left pedal for all phases of flight
In high density altitude situations, what happens to ETL?
It requires a higher forward velocity. You don’t gain it until later on take off, you lose it sooner on landing
What happens to true airspeed at higher DA?
True airspeed becomes higher
What are three landing site considerations?
Elevation, temperature, obstacles
What are the three power numbers one must have before going into a remote?
Power available, power required, and power margin
The “W” in WETPASTE stands for what?
Winds, Turbulence, and null areas
The first “E” in WETPASTE stands for what?
Elevation of landing site
The first “T” in WETPASTE stands for what?
Temperature and Pressure altitude
The “P” in WETPASTE stands for what?
Power available, required, and margin
The “A” in WETPASTE stands for what?
Approach/departure, obstacles, and go/no point
The “S” in WETPASTE stands for what?
Suitability of site
The second “T” in WETPASTE stands for what?
Touchdown point
The “E” in WETPASTE stands for what?
Escape route
What pattern is useable in an unconfined area?
Racetrack
What patter is more useful in a confined area?
Circle or orbit
What can occur at mountain tops which results in locally warmer temperatures?
The bubble effect on mountain tops. More likely in dense vegetation
How does one calculate PA from site elevation?
Add 10 feet for every.01 inch the altimeter setting is below 29.92 or subject if above
How does one calculate the PA of the site?
Subtracting radar altimeter number from barometric altimeter set to 29.92
What is the minimum power that must be available to land at a remote?
5ft hover power
When operating at a small RT (smaller than 2 rotor diameters) what is the required power available?
OGE hover power or greater
What is the go/no go point for remotes?
The point at which maximum power available is insufficient to go around.
Approach angle to an RT must be steep enough to allow for what?
Clear obstacles by 25’
Steep approaches have what advantages?
Excellent visibility of the RT, more altitude to emergencies, enables landing at a smaller RT
Steep approaches have what disadvantages?
Poor closure cues, more power required
Shallow approaches have what advantages?
Better closure cues, less power required
Shallow approaches have what disadvantages?
Requires a larger RT, poor visibility of the RT, less altitude for emergencies
What is the 4-torque reference?
Charted, predicted, expended, actual
Charted torque refers to?
What does the chart say you need
Predicted torque refers to?
What do I need to add since the chart doesn’t account for everything. A “fudge factor”
Expended torque refers to?
What was actually utilized for the manuever (Execute the maneuver and see what was actually used)
Actual torque refers to what?
What is the real torque actually required for hover and takeoff
