Chart Layout and Annotation

CHAPTER SIX

SECTION LOW ALTITUDE TACTICS AND PROCEDURES

Highlight the corridor.

6. Leave the official AP-1/B points on the chart in ink so that it is an easy reference in case

we need to report our position to ATC.

Use a combat plotter to plot each turnpoint in pencil with the 300-knot circle.

Use a combat plotter to plot a turn radius for every turn greater than 30 degrees.

The target triangle is a 5 NM equilateral triangle.

10. Time tick every minute based on 5NM/MIN at a speed of 300 KTS to the IP. From the IP

to the target, tick every minute based on 6NM/MIN at a speed of 360 KTS. For every time tick,

draw a line 3NM on either side of centerline; on every third time tick, draw a 5NM tick either

side of centerline and label the corresponding time.

11. Assume no wind for planning purposes. The OUI will obtain forecast winds prior to

takeoff. If route winds are forecast to be 20 knots or greater, adjust no-wind headings and base

airspeed as necessary to maintain pre-planned course and time. If winds are less than twenty

knots, fly pre-planned headings and airspeed. Remember at 300 KTS, 1 of crab is required for

each 5 knots of crosswind.

12. The strip chart should encompass the area 10NM on either side of the route centerline.

This allows adequate chart reference in the event the flight is off course. (Remember: flight

outside the route is not authorized).

13. Label each turnpoint or target with the appropriate LETTER and time. Orient the

information parallel to the inbound course. Measure distances to each turnpoint to the nearest

NM. This means your times will be labeled in six-second intervals.

14. Special use airspace such as Restricted Areas and MOAs shall be highlighted and annotated

on your chart. Annotate all areas within 20 NM of course. They shall also include altitudes,

operating times, and any frequencies that require transmission. Additionally, annotate all class

`C' airspace by drawing a 10 NM circle around the airfield.

15. Hazards to flight shall be annotated on all charts. Hazards include the following:

All towers and obstructions within 5NM of course whose altitude is 300 FT AGL or

greater. These must be verbalized on the route as a hazard as well.

Hard surfaced airports within 5NM of course. These should be avoided by 3NM or

1500 ft.

A photocopy of the AP-1B route description will be glued to the strip chart cover. "Z" diagrams

(to be addressed later in this chapter) will be adjusted for terrain elevation, depicted in the

margin near the target, and annotated in MSL altitudes.
