Racine, February 4, 2004:                DeltaHawk’s Velocity test aircraft was used to determine the cold start capability of The DH160V4 engine.  The plane was taken from a 50° F hangar and parked on the ramp for 4 hours exposed to a 20° F ambient temperature and a 5-7 knot wind.  No pre-heat or other starting aids were used prior to, or during the exposure period.  The engine started and ran smoothly after half a dozen 2-3 second starter engagements.

 Previous to this we have started it on the ramp immediately after removing from the hanger at a temperature of zero Fahrenheit.  Engine block temperature was 50° F.
