[REPORTED]HUD SYM thumwheel ON before engine start=HUD OFF

[F16FLCS-SME]

Before doing anything else:

1. From cold start, turn HUD SYM thumbwheel all the way up.

2. HUD will not come ON (as expected) since there is no power.

3. Close the canopy and start the engine.

4. When engine at idle and MAIN GEN light is OFF, look at the HUD. It is still OFF!

5. Turn the AVIONICS POWER MMC switch to ON.

6. HUD will come ON!

7. Turn the MMC power to OFF.

8. HUD will stay ON!

HUD should come ON regardless of MMC power.

HUD Symbology may be all zeroes or other defualt values but HUD power should be ON.
