Performance Measures

Performance Measures	Go	No Go
1. Position howitzer within 1 meter of survey control point toward distant aiming point.
2. With the STEER TO FIRE AREA screen displayed read and record AFCS position data under POSN (easting, northing and altitude) and the range to destination (RNG) in the upper right corner of the screen. Subtract the POSN altitude from the DESTN altitude. Compare the data obtained with the following tolerances: RNG                                26 meters or less Altitude Difference            +/- 26 meters Note: If the data is within tolerance but not exact, do a position navigation update.
3. Press ARRIVED key.
4. Check boresight of the pantel with M140 alignment device.
5. Using the azimuth deflection knob align the vertical hair line of the pantel on the distant aiming point, level the pitch and cross level bubbles, and check alignment.
6. Rotate counter reset knob on pantel until 3200 appears on the reset counter.
7. Remove tube from the stowed position, install breech boresighting disc, and muzzle cross hairs on tube.
8. Using the boresighting disc, align the tube on the distant aiming point. Note: Primer vent hole may be used if boresighting disc is missing.
9. Level pitch and cross level bubbles on pantel mount and realign vertical hair line on pantel using the azimuth deflection knob.
10. Using the auxiliary quadrant, level the elevation vial.
11. If fire mission screen is not already displayed select fire commands menu from the setup and information menu to display fire mission screen.
12. Read the actual deflection and quadrant on the AFCS and compare them with the deflection and quadrant obtained in steps 9 and 10. The tolerance between the readings should be +/- 2 mils. Note: Quadrant should also be checked with a pretested gunner's quadrant. Reading should compare to +/- 2 mils.
13. Select display format from the setup and information menu.
14. Change display from deflection to azimuth and return to the fire mission menu. Read the actual azimuth.
15. Compare the azimuth displayed on the AFCS with the measured azimuth to the distant aiming point. Azimuth should compare to +/- 2 mils.

If the soldier scored "no go", tell him and write a brief explanation in the space below.
