22
Q

Terrain Flight Planning Standards

A
  1. Analyze the mission using the factors of METT-C
  2. Perform a map/photo recon using the available map media or photos. Ensure all known hazards are plotted.
  3. Select the appropriate terrain flight modes and techniques of movement
  4. Select appropriate primary and alternate routes and enter them on a map or route sketch
  5. Determine the distance +- 1km, ground speed +- 5 knots, and estimated time enroute (ETE) +- 1 minute for each leg of the flight
  6. Determine the fuel required +-100lbs
  7. Obtain and analyze weather briefing to determine that weather and environmental considerations are adequate to complete the mission
  8. Conduct a thorough crew mission briefing
23
Q

Wind recognition: Ground indicators

A

Bodies of water
Smoke
Leaves (will appear lighter in color on the upwind side of a tree and darker on the downwind side
Tall grass

Mandmade indicators such as wind socks, flags, or smoke grenades

Blowing snow, dust, and sand

24
Q

Wind recognition: Aircraft indicators

A

Determined by aircraft reaction and its apparent movement over the ground
-aircraft drifts from the desired ground
track
-difference between apparent ground
speed and indicated airspeed
-an increase/decrease of power from a
previous setting for airspeed
(updrafts/downdrafts)

The direction and magnitude of a crab angle will indicate the winds at your flight level. Calculating the winds aloft from known distance flwo, time, magnetic, and true course is possible if time permits

25
Q

Wind recognition: Cockpit indicators

A

Tools to determine and/or monitor wind conditions
-Navigation display (ND)- provides a wind vector with infor like direction and speed
-Drift indicator will relay the current ground track
-Garmin will show wind vector showing direction and numerical velocity on map page

26
Q

Continually re-evaluate wind recognition by comparing:

A

Forecast vs. actual wind

27
Q

Hazards to terrain flight

A

M- meteorological
P-physical
mandmade
wires ( commo, power, guy, booby
traps, tow)
natural
H-human

Q

Fundamentals of Reconnaissance

A

GORRDDE
-Gain and maintain enemy contact.
