The new Sight Status and Weapon Status Field prompts replace the existing, lowest priority displays. The new displays are out–prioritized by all other HAD displays. M01-0351 123:2N H:MMT43 Figure 3-25.24. PILOT HIGH ACTION DISPLAY (HAD) a. Sight Status Field. The Sight Status Field is modi- fied to provide Distance–To–Go from PPOS to the se- lected FLY–To location. Character space 1 and 2 are blank. Character spaces 3 to 8 provide the Distance–To– Go, with a colon in space 6 (providing 100 meter resolu- tion to the pilot) and a K or N (Kilometers or Nautical miles) in space 8. Units are selectable by the CPG using the CDU. All numerals in this display are refreshed at 1Hz. b. Weapon Status Field. The Weapon Status Field provides, as its three lowest priorities prompts, HSI CUE?, Time–To–Go (TTG) from PPOS to the selected FLY–TO and the active fly_to symbol. The HSI CUE? is the highest priority and is the same indication to the pilot as the advi- sory message DNS/HSI NAV CUES ?? is to the CPG. It is removed from the pilot weapon status display when the CPG clears the Advisory message. The TTG display is the lowest priority and is in hours and minutes (H:MM) if the TTG is greater than 5 minutes. This display changes to minutes and seconds (M:SS) when TTG is less than 5 minutes. The first character space will be H (Hours) or M (minutes). The second character space is a colon (:). The third and fourth character spaces will be either MM (min- ute values 00 to 59) or SS second values 00 to 59). The fifth, sixth and seventh character spaces will display the fly–to symbol (W01 through T80) The eighth character space is blank. All characters relating to TTG become dashed when the TTG is greater than 9 hours and 59 min- utes or the ground speed is less than 10 KTS. c. Trim Ball. The trim ball will flash when the HARS has been free inertial for 20 seconds or more, and aircraft groundspeed is less than 10 knots.
