Q
  1. What is the difference between EARLY and OVER options on the flight plan screen?
A
  • When OVER (overfly) is active, the aircraft will overfly the way- point and will fly a teardrop pattern to intercept the outbound leg.
  • When the capture criteria is EARLY and the turn is less than 120°, the helicopter will roll out exactly on the next leg of the flight plan. When the turn is greater than 120° the helicopter will fly a teardrop pattern to intercept the outbound leg. (Leads the turn)

Q

2.

(1) What information is provided in each FMS header default?
(2) According to the student handout, how do you change the header?

A

(1) Defaults:

Pilots, NAV

Co-pilots: COM

See image for information.

(2) I don’t know what student handout they are talking about, but -10 says: “Header selection can be changed on initialization page 3/3 or on the PPS page.”

Q
  1. Referencing the Tactical Flight Mission Planning and Map Preparation Guide (TFMP), Selecting appropriate altitude(s) and terrain flight modes as appropriate: The _____________ terrain flight altitude for the specific condition should always be used. Flight at _________ terrain flight altitudes reduces the __________ ____ __________, enables ________ airspeeds, reduces __________ to terrain flight, and minimizes __________.
A

Referencing the Tactical Flight Mission Planning and Map Preparation Guide (TFMP), Selecting appropriate altitude(s) and terrain flight modes as appropriate: The highest terrain flight altitude for the specific condition should always be used. Flight at higher terrain flight altitudes reduces the difficulty of navigation , enables higher airspeeds, reduces hazards to terrain flight, and minimizes fatigue .

Q
  1. How does the TFMP define Air Control Point, where are they designated and what may allow them to be placed farther apart?
A

Air Control Point (ACP) - - An easily identifiable point on the terrain or an electronic NAVAID used to provide necessary control during air movement

ACPs are generally designated at each point where the flight route or air corridor makes a definite change in any direction and at any other point deemed necessary for timing or control of the operation. ACPs should be progressively closer as an aircraft nears the objective, facilitating timing and navigation. Type of terrain, illumination, total route distance, and accuracy of onboard navigation systems may allow selection of ACPs much further apart.

Q
  1. What are the two basic maps used in tactical flight mission planning (1), and what are the advantages/disadvantages of each (2)?
A
  • JOG and the tactical map.
  1. The Joint Operations Graphic has a scale of 1:250,000. The scale of the map permits a relatively small map uncluttered with extraneous information. It shows coordinates in Latitude and Longitude, as well as Military Grid Reference System (MGRS). It is useful for performing long enroute legs performed at Low Level. However, because it lacks adequate terrain detail, it should not be used for Contour or Nap of the Earth (NOE) planning and navigation.
  2. b. The tactical map has a scale of 1:50,000 and is a highly detailed map. This is the primary map used for the objective phase of the operation. It should be used anytime Contour or NOE flight is conducted, or anytime precise navigation is required (i.e. at a PZ or LZ).

Q
  1. What does the TFMP state you should consider when planning and plotting routes regarding:
  • Location of SP & RP
  • Selection of ACPs
  • Turns enroute
  • Route width
  • and Course to the RP and final course from RP to LZ .
A

What does the TFMP state you should consider when planning and plotting routes regarding:

  • Location of SP & RP
    • Locate the SP 3 to 8 kilometers from the PZ’s. The flight route starts here.
    • Locate the RP 3 to 8 kilometers from the LZ’s, for both primary and alternate routes. Flight route ends here.
  • Selection of ACPs
    • Select prominent, distinct terrain features located along the flight route that facilitates navigation, control of speed, and control of en route fires as ACP.
  • Turns enroute
    • Plan for no turn to exceed 60 degrees, especially during sling or multi ship.
  • Route width
    • Plan that routes are at least 2 kilometers wide.
  • and Course to the RP and final course from RP to LZ .
    • Ensure the course to the RP is within 30 degrees of the final course and the final course is within 30 degrees of the LZ landing heading.
