Douglas DC-5 Pilot's Handling Notes **
******************************************************************
The two 900hp Wright Cyclone G102A engines have manual
mixture controls,
and are carburetted with
manually applied carb heat controls.
They are modestly supercharged to give rated power
up to 6700 feet. 1100hp is available for take off at low altitude.
Unless you have real life experience of controlling
the mixture of aero
engines selection of automixture
control from the realism screen before
flight is strongly recommended. Use of automixture is assumed in these
handling notes.
AVOID - running Cyclone engines undersquare
This aircraft is loaded with the maximum allowable 550
USG (3300lbs)
of AVGAS. Passenger load is therefore restricted to 10
passengers plus
bags. For flights of less than two hours duration 200
USG (1200lbs)
of the default fuel must be removed before flight
using the FS9 fuel
and payload menu to comply with the landing weight restiction which
is 18,300lbs. Payload may NOT be added in lieu.
See aircraft.cfg for futher
details.
This aircraft is unpressurised and has no oxygen
supply for crew
or passengers. Design cruise altitude is FL100.
Altitude changes > 700 VSI should be avoided.
CAUTION - This aircraft has VERY FRAGILE flaps.
