When both genties open with both generators on line and you manually close them, would you see MAN CLOSE green annunciation light?

No, the MAN TIES CLOSE annunciator activates only when the generator bus tie relays are manually closed using the switch. If both generators are online and operating normally, the bus ties close automatically, and the MAN TIES CLOSE annunciator does not activate.

King Air 350 abnormal checklist: Both Gen Ties Open. You Manually close the Gen Ties with both Generators on line. Why, the next step in the checklist says: MAN TIES CLOSE-ILLUMINATED? They shouldn’t be since both generators are on line.

The "MAN TIES CLOSE" annunciator illuminates when the generator bus tie relays are manually closed, completing a latching circuit. This prevents the automatic closing of the bus ties and activates the annunciator readouts. Even if both generators are online, the manual closure of the Gen Ties switch forces the relays to stay closed, triggering the indication.

Abnormal checklist BOTH GEN TIES OPEN.
You manually close them. Next step in checklist:
MAN TIES ILLUMINATED. They shouldn’t be since generators are on line. Does that mean ANY time you manually close them regardless of generator status, the MAN CLOSED light illuminates?

AVIONICS INTRODUCTION The King Air C90GTi/C90GTx utilizes the Collins Pro Line 21 avionics system. The Pro Line 21 Avionics System is an integrated flight instrument, autopilot, and navigation sys- tem. All functions have been combined into a compact, highly reliable system designed for ease of operation, seamless communication between systems, and reduced pilot workload.

KING AIR 90 SERIES PILOT TRAINING MANUAL CHAPTER 16A WIDE AREA AUGMENTATION SYSTEM (WAAS) INTRODUCTION For the standard GPS system to provide lower minimums on an approach the GPS sig- nal needed to be corrected. The correction was primarily needed to increase the accu- racy of vertical navigation but lateral navigation was also improved.

Need help?
Do you have a question about the C90GTi and is the answer not in the manual?
Questions and answers
When both genties open with both generators on line and you manually close them, would you see MAN CLOSE green annunciation light?
No, the MAN TIES CLOSE annunciator activates only when the generator bus tie relays are manually closed using the switch. If both generators are online and operating normally, the bus ties close automatically, and the MAN TIES CLOSE annunciator does not activate.

King Air 350 abnormal checklist: Both Gen Ties Open. You Manually close the Gen Ties with both Generators on line. Why, the next step in the checklist says: MAN TIES CLOSE-ILLUMINATED? They shouldn’t be since both generators are on line.
The "MAN TIES CLOSE" annunciator illuminates when the generator bus tie relays are manually closed, completing a latching circuit. This prevents the automatic closing of the bus ties and activates the annunciator readouts. Even if both generators are online, the manual closure of the Gen Ties switch forces the relays to stay closed, triggering the indication.

Thank you so much! Joe
Abnormal checklist BOTH GEN TIES OPEN. You manually close them. Next step in checklist: MAN TIES ILLUMINATED. They shouldn’t be since generators are on line. Does that mean ANY time you manually close them regardless of generator status, the MAN CLOSED light illuminates?
