Securaplane received a TSO 
for its XL500/5 Emergency Battery System  
that is a direct replacement for 
DC versions of PS-835 B/D and PS-855B

On July 28, Securaplane received a Technical Standard Order (TSO C4c) 
authorization from the Federal Aviation Administration for its XL500/5 
Emergency Battery System. 

The XL500 series emergency batteries are the most technically advanced 
1/4 ATR battery packs available today.  Features include extensive 
diagnostics, a built-in charger to ensure peak charge state, and built-
in test capability.  There is no deep cycling required and no memory 
characteristics.

The XL500/5 has been selected for the Raytheon (Beech) Premier 1 
aircraft and is similar in concept to Securaplane's reliable XL246 (over 
1000 in use) series of Emergency Battery Systems currently in use on 
Gulfstream GIII and GIV, Canadair Challenger, Falcon and other aircraft.

Securaplane 1/4 ATR emergency batteries in XL500 series include:

XL500/5 - 3.5 AH at one hour rate with emergency lighting 5VDC output
XL500 - 3.5 AH at one hour rate without emergency lighting 5VDC output
XL250/5 - 1.8 AH at one hour rate with emergency lighting 5VDC output
XL250 - 1.8 AH at one hour rate without emergency lighting 5VDC output

Securaplane is a designer and manufacturer of emergency power systems,
