Martin M-130 Pilot's Handling Notes - Original engines 1935 - 1937
*******************************************************************
SUMMARY.
This M-130 has four 830hp Pratt & Whitney
R-1830-S1A-2G Twin Wasp engines which are carburetted and slightly
supercharged. 900hp is briefly available for TOGA. The (virtual) flight
engineer selects fine pitch for take off and will select course pitch for
cruise climb and cruise. These engines have automixture. Set
WARNING - If significant headwinds are encountered during first half of a long haul flight return to point of departure. If significant headwinds are encountered during a short haul flight, or late in a long haul flight continue to destination, descend to 500 feet and apply cruise climb power. This will yield 129 KTAS at 500 feet at 41,000lbs (Plan 1250 PPH).
WARNING - maximum safe landing weight is 48,000lbs but normal landing weight is 32,000lbs
CAUTION - This aircraft is unpressurised do not exceed FL120.
Maximum fuel load is 24,462 pounds for propaganda flights, but normal and default fuel load is only 21,000 pounds. All fuel burn figures are for planning purposes and will vary slightly with altitude. Adjust fuel and payload using the FS9 fuel and payload menu.

HANDLING THE AIRCRAFT
****************************
Take Off:
MIXTURE = AUTO in realism screen
CARB HEAT = COLD
COWL FLAPS = 4 degrees
TRIM + 4 degrees (use wheel tooltip for guidance)
CALL for FINE PITCH
CALL for TOGA POWER (4 x 900hp)
Slowly apply FULL THROTTLE
ROTATE at 80 KIAS (@ 51000lbs)
Establish positive rate of climb
CLIMB = 200 feet ASL <= 100 KIAS
ENGINEER SELECTS COURSE PITCH
Note RPM DECREASE @ 100 KIAS
= 200 ASL ACCELERATE = 115 KIAS
Begin CRUISE CLIMB (@ 75% METO)
**********************************
Cruise Climb: (75% METO = 625hp x 4)
COWL FLAPS = 2 degrees
MAP = 29 (max)
Cruise / Climb = 115 KIAS
Plan 1200 PPH
Note: Yields 141 KTAS @ FL70 @ 41000lbs
WHEN weight = 39,000lbs and nil wind
Begin LIGHT CRUISE CLIMB (@ 60% METO)
***********************************
Light Cruise Climb: (60% METO = 500hp x 4)
Use < 39000lbs
Use only with no significant headwind
COWL FLAPS = Closed
MAP = 25 (max)
Cruise / Climb = 115 KIAS
Plan 1000 PPH
Note: Yields 136 KTAS @ FL120 @ 39000lbs
****************************
METO Power (830hp x 3)
After engine failure or for go around
COWL FLAPS = 4 degrees
MAP = 35
Plan 1250 PPH (3 engines)
**********************************
Descent:
DO NOT EXCEED Vno = 150 KIAS
COWLS = CLOSED
REDUCE MAP <= 3 inches per minute
115 KIAS
See CARB HEAT below
*****************************
Approach and Circuit:
COWL FLAPS = 2 degrees
Downwind abeam touchdown zone
REDUCE = 80 KIAS
Touch down @ 70 KIAS (@ 32,000lbs)
COWL FLAPS = FULL OPEN
****************************
Carb Heat:
When < 30 inches MAP with an OAT below 5C (40F)
use carb heat periodically to clear carburettor ice.
Continuous use of carb heat is not recommended.
NOTE: You must Reload Aircraft before taking off
again.
