Re-engined Martin M-130 Pilot's Handling Notes

**********************************************

 

SUMMARY.

 

During 1937 this M-130 has been re-engined with four 950hp Pratt & Whitney R-1830-SB-G Twin Wasp engines which are carburetted and slightly supercharged. 1000hp is briefly available for TOGA. The constant speed propellers can be feathered. These engines have automixture set AUTOMIXTURE ON in the realism screen.

 

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 137 KTAS at 500 feet at 42,000lbs (Plan 1400 PPH).

 

WARNING - maximum safe landing weight is 48,000lbs but normal landing weight is 33,000lbs

 

CAUTION - This aircraft is unpressurised do not exceed FL120.

 

Maximum fuel load is 24,462 pounds forp propaganda flights, but normal and default fuel load is only 21,000 pounds. All fuel burn figures are for planning puposes 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 TOGA POWER  (4 x 1000hp)

 

PROPS = MAX RPM

 

Slowly apply FULL THROTTLE

 

ROTATE at 80 KIAS  (@ 52000lbs)

 

Establish positive rate of climb

 

CLIMB 200 feet ASL

 

ACCELERATE > 100 KIAS <= 500 VSI

 

Begin Cruise Climb (75% METO)

 

**********************************

 

Cruise Climb Power: (710hp x 4)

 

COWL FLAPS = 2 degrees

 

MAP = 30 (max)

 

RPM = 2000

 

Cruise Climb = 115 KIAS

 

Plan 1400 PPH

 

Note: Yields 149 KTAS @ FL120 @ 42000lbs

 

WHEN weight = 42,000lbs and nil wind

 

APPLY light weight cruise power (60% METO)

 

***********************************

 

Light weight Cruise / Climb: (570hp x 4)

 

Use < 42000lbs

 

Use only with no significant headwind

 

COWL FLAPS = Closed

 

MAP = 26 inches

 

RPM = 1850

 

115 KIAS

 

Plan 1000 PPH

 

Note: Yields 136 KTAS @ FL120 @ 42000lbs

 

****************************

 

METO Power (950hp x 3)

 

Use only after engine failure

 

COWL FLAPS = 4 degrees

 

MAP = 36

 

RPM = 2250

 

Plan 1450 PPH (3 engines)

 

**********************************

 

Descent:

 

DO NOT EXCEED Vno = 150 KIAS

 

COWLS = CLOSED

 

RPM = 1850

 

REDUCE MAP in stages of 3 inches (per minute)

 

MAP => 19

 

See CARB HEAT below

 

*****************************

 

Approach and Circuit:

 

COWL FLAPS = 2 degrees

 

RPM = 2300 RPM

 

MAP = 23 inches

 

 

Downwind abeam touchdown zone

 

No MAP restriction

 

REDUCE = 80 KIAS

 

 

Touch down @ 70 KIAS (@ 33,000lbs)

 

 

COWL FLAPS = FULL OPEN

 

PROPS = MAX RPM for taxi

 

****************************

 

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.
