ADS Offers Dual Battery Starting System and STC for Dash 8 Aircraft Family
Modification allows better cold weather starting capabilities on DHC-8 100/200/300
TORONTO – ADS has a dual battery starting system for the 100, 200 and 300 Dash 8 aircraft. The system gives better cold weather starting capability for these aircraft types.
“This modification allows the auxiliary battery to be tied to the main battery during the engine start sequence.” said Bob Gow, president of ADS. “The system is available on the ground, before any of the generators are on line and if ground power is not present. Otherwise, it is inactive.”
The kit, which includes all parts except the STC documentation and consumables consists of a large nose-installed power contractor, four small signal relays installed in the wardrobe, a circuit breaker on the LH essential bus and the annunciator in the overhead panel. The total weight of the system, including wire, is 12 lbs. The aircraft must be fitted with two Hawker 43 ampere-hour sealed lead acid batteries in accordance with STC SA04-31 to apply this modification.
More About the Dual Battery Starting System
The system is armed using a switch on the overhead panel adjacent to the existing engine start switch. When the existing engine start switch is engaged, a high-power relay closes to connect the auxiliary battery to the start bus to assist the main battery. An annunciator in the overhead panel, adjacent to the start panel, controls the system. Once the Engine Start Switch is selected to either engine the “AVAIL” light illuminates and the system may be activated by pressing the annunciator switch. The ON light will illuminate. Once the starter drops out, the system deactivates. A safety interlock prevents the batteries from being paralleled after a start sequence begins.
