[2.9.21.16552] Position of nose/tail arm switch has no effect on ARM lights illumination

[Stickler]

According to the RL F-4E flight manual, the nose/tail arm switch closes a fuze select-ready relay in the BOMBS/station ARM light circuit. With the weapon selector in BOMBS, the station ARM light will not illuminate unless the nose/tail arm switch is energized. Conversely, the SAFE position of the switch does not inhibit the BOMBS release circuit. Bombs will release (SAFE) if all other release controls are energized and with only the station green light(s) ON. Therefore, the pilot will notice that with BOMBS selected and station green light(s) ON, an ARM-light-OFF indication does not necessarily mean that the bomb button circuit is in a SAFE condition. If the BOMBS position is used to bomb-off rocket or CBU dispensers in a jettison situation, then the nose/tail arm switch should be in one of the (ON) positions to get the proper station ARM light indications (MER/TER stations empty).

As seen in the attached track, the position of the nose/tail arm switch currently has no effect on whether the ARM lights illuminate or not.
