Timing Triangle CNI-MU ETA
Turn away from course line until CNI-MU ETA equals your pre-planned turn point time Can be used to cut off legs without much effort Works well if you are early
26
Timing Techniques Ten Knot Rule of Thumb
Increase/decrease GS by 10 kts from planned Will gain/lose 1 second for every 1 NM traveled
27
Timing Technique Incremental Method (deviations less than 1 min)
Divide planned IAS by 6 Apply this to planned airspeed for 1 minute You will gain/lose 10 seconds
28
Timing techniques Proportional method
Increase/decrease planned IAS by same number of seconds late/early Hold this correction for the time (in seconds) equal to flight planned IAS
29
Why should you avoid large bodies of water?
Camouflage is less effective; sound travels farther and radar detection is more likely
30
How to use sun to your advantage when flying
Plan to fly in shadows when possible Place aircraft shadow in terrain shadow Early morning or late afternoon since sun at low angle Hide shadow in a ridge line, ridge shadow, cloud shadow, or dark vegetation
31
How many degrees within should the IP be planned from the DZ/ALZ run in
Within 30 degrees
32
What is direct masking?
Preferred and most effective method of terrain masking Placing terrain directly between aircraft and threat
33
What is horizon masking?
Maintaining a sufficient standoff distance and altitude to deny radar detection. Ducting can increase or decrease radar detection range of a system
34
What is indirect masking?
Placing aircraft so close to terrain that it is inside the radar resolution cell of the threat radar (one-half the pulse width, and cannot be broken out from the ground clutter)
35
What is one-half beam width masking?
Placing aircraft low enough to terrain to stay in the lower half of the radar beam causing ground clutter to mask radar signature
36
How should you ingress with regards to the sun position?
Fly early morning or late evening Ingress with the sun to the back of the aircraft. Makes detection and possible engagement from various weapons systems more difficult
37
What do aeronautical charts NOT depict? What is the worst situation?
Man-made obstacles less than 200 ft nor a change in terrain until it exceeds the chart contour interval If a 199 ft tower sat on terrain with an elevation just below the next higher contour interval. If contour interval is 500 ft then this would result in an uncharted obstacle 698 ft above charted terrain
38
What are some considerations for route selection when flying on NVDs? (answers don't include all that are listed in ANTTP)
Avoid brightly lit areas, roads, and population centers Avoid navigational aids and airports Avoid heading changes greater than 60 degrees Negotiate large valleys on the illuminated side from moons position Avoid flying directly into low rising or setting moon Do not use towers as checkpoints
39
Why should you not use towers as checkpoints on NVDs?
Generally lit with overt lights that degrade NVDs Normally have guided wires associated with them that can’t be detected Some tower use low cost LED lights that may not be seen on NVDs
40
How long should the leg from IP to objective be and why?
Never have a leg longer than 10-15 nm, to preclude compromise of the objective and to facilitate accurate timing
41
What chart should be used for planning and briefing? For objective and terminal area planning?
JOG (1:250,000) Objective area - 1:50,000
42
What angle of bank turn should you plan for low levels?
30 degrees
43
What is tactical pilotage?
Navigation using visual means to compare features found on a chart to those same features on the ground
44
What are the 3 general stress moments acting on the aircraft?
Torsion Shear Bending
45
Describe Torsion
Wringing a towel If aircraft abruptly maneuvered around roll axis, wings initiate movement and tail follows. Empennage is last portion to move since movement is transferred from wings to fuselage to empennage
46
When is torsion greatest?
When aileron inputs are performed in fewer than 0.3 seconds
47
Describe Shear
Compared to an earthquake When an abrupt change about an axis is performed and quickly reversed Example: beginning a rapid climb, abruptly stopping, and initiating a rapid descent Elevator initiates movement, wings last to react and still moving upward even though empennage is beginning a descent
48
Describe bending
Readily seen by the upward bowed wings with a heavy gross weight - same occurs during high G loads Under 2 Gs the fuselage doubles in weight. Wings bend upwards trying to maintain sufficient lift for the increased total load
49
When do highest bending moments occur?
When maximum accelerated loads are imposed within 0.3 seconds
50
When can loads imposed on aircraft exceed the design limits?
Inputs made within 0.3 seconds
51
Which wing in a turn experiences additional Gs?
Rising wing
52
What is dead reckoning?
Calculating ones position based on the direction and distance one has traveled rather than using landmarks
53
What is the correct technique for tactical pilotage?
Check the chart and the clock to locate your probable position then look ahead on the ground
54
What are the 3 landmark categories?
Positive, linear, uncertain
55
What are positive landmarks?
Ones that can positively identified and plotted at a point on the chart
56
What are linear landmarks?
Ones that can positively identified, but not specifically plotted, because they extend for some distance Roads, railroads, coastline, power lines, river but only if perpendicular to course A bend in a road or river could be a positive landmark
57
What are uncertain landmarks?
Features you suspect correlate with the chart, but are not fully reliable. Not good for making heading changes Can cue you to more reliable, positive landmarks Small lakes, farms, windmills, something frequently duplicated
58
When does the INS only solution begin to drift?
At takeoff
59
When will the EGI, if GPS becomes unavailable, begin to drift and at what rate?
From its last updated position, at the INS drift rate
60
What will be displayed if system determines the GPS is being jammed?
A “J” is displayed under the satellite status and you can expect a GPS FOM DEGRADED advisory
61
When approaching a ridge line what kind of winds should be you cautious of?
Tailwind - results in possible loss of lift Winds greater than 25 kts - indicates possible mountain wave turbulence
62
Where should you set the FPA?
1 degree below climb angle
63
When turning into terrain what AOB should be established initially?
60
64
What does the CDM project?
Projected aircraft vertical flight path under current energy conditions and loss of energy resulting from a climb must be considered by the PF
65
When flying down a valley what should you do?
Remain on the downwind side whenever possible This minimizes mountain wave downdrafts and allows turns into the wind that effectively decreases the turn radius
66
What does the Ghost Flight Path indicator project?
will provide the actual aircraft flight path including the lateral component. There can be a significant difference between the CDM and the Ghost Flight Path with high crosswinds.
67
Flight planning emphasis should be placed on the environment at least __ NM either side of the intended flight path.
10 NM
68
VR routes were created for who? SR routes?
VR - airspeed >250 kts SR - speed <250 kts at or below 1500' AGL
69
How do you get an LSA?
determined by separating the route leg into segments based on changes in terrain, and climb/descent rates once leg segment determined, add 1000' AGL to highest obstacle/terrain within 5 NM of that segment
70
When would you fly an LSA?
when terrain is not visually discernible flying into a setting/rising sun, blowing dust, illumination level below anticipated
71
What is the optimum exterior lighting pattern when countering an enemy known to have NVDs?
place formation lights to low with no other exterior lights or extinguish all external lighting. minimize cockpit lighting, use cargo compartment porthole covers, and minimize cargo compartment lighting especially during airdrops
72
What are the 3 vulnerabilities that radars have?
- limits on maximum detection range - degraded low-altitude detection capabilities bc of curvature of Earth - masking properties of obstructions btwn antenna and a/c
73
TACNAV How high should you plan routes? How low should you plan routes?
As high as the threat will allow As low as the threat demands
74
What are some significant contributors to visual detection?
Aircraft shadow from flying too low Wing flash (reflected light) - easier to see and increases RCS - limit turns to 20-30 AOB when possible

green
76
TACNAV Where are optimum emergency airfields located?
within 50 NM of intended route, approx. every 100 NM

reflective
78
When performing air delivery missions, attempts should be made to load the aircraft so that the CG is as close to what? why?
center or slightly aft unexpected turbulence or a requirement to expeditiously climb with a forward CG increases the potential of overstressing the tail section bc of a long moment arm
79
When turning around terrain what AOB should be established? How long do you hold it?
60 degrees initially AOB can be reduced to increase lateral separation from terrain
80
