GLA Limitations Flashcards

Question

Max. Weight in Forward Cabin Closet

Answer 1

100 lbs/sq. ft

Answer 2

Green arc - normal operating limits (17.5 - 20) | Red Line - Maximum Operating Limit (20 PSI)

Answer 3

Wide Green Arc - Normal Operating Gauge

Answer 4

Do not lift the power levers in flight. Lifting the power levers in flight, or moving the power levers in flight below the flight idle position, could result in a nose down pitch and descent rate leading to aircraft damage and injury to personnel

Answer 5

Green Arc - Normal Operating Range - no limitation Yellow Arc - Caution Range 5 minutes Transient Limit - 5000 lbs Note: these torque limits apply within the range of 1,000-1,700 rpm (Np) Below 1,000 RPM the torque limit is 2,000 lbs Cruise torque varies with altitude and temperature

Answer 6

5000 lbs (20 sec. max)

Answer 7

Caution range - 5 Minutes

Answer 8

750 degrees

Answer 9

760 degrees

Answer 10

Normal Operating Range - No limitations

Answer 11

Caution Range - 5 Minutes

Answer 12

Idle - 750 degrees Cruise climb/max cruise/max reverse - 760 degrees Green arc (normal operating range) - no limitations Yellow Arc (caution range) - 5 minutes Red Line - 5 Minutes Red Diamond (starting limit) - 5 seconds

Answer 13

Green Arc - Normal Operating Range | Red Line - Maximum Limit

Answer 14

Normal Maximum Limit - 20 Seconds

Answer 15

Normal Operating Range - No limitations at or greater than 72% N1

Answer 16

Caution Range - Torque Limited to 2,000 ft/lbs With torque below 3,000 lbs. Min oil pressure = 85 psi at normal oil temp Except oil pressure below 90 psi is undesirable to be tolerated only for the completion of the flight and then only at reduced power setting not exceeding 2,000 lbs torque - with oil pressure below 90 psi Record oil, torque, elapsed time during which the engine was operated under those conditions

Answer 17

Oil pressure below 60 PSI Unsafe requires one of the following - engine shut down - landing at the nearest suitable airport using the minimum power required to sustain flight

Answer 18

Red Line - normal max limit - 20 seconds Green arc (normal operating range) - no limits at or above 72% n1 Yellow arc (caution range) - torque limited to 2,000 ft/lbs - torque below 3,000 lbs minimum oil pressure is 85 PSI at normal oil temp (60-70 degrees) - oil pressure below 90 psi torque limited to 2,000 lbs, must record time elapsed, oil psi and torque setting placed in discrepancy write up ``` Red line Oil pressure below 60 PSI Expect one of the following - engine shut down - landing at the nearest suitable airport using the minimum power required to sustain flight ```

Answer 19

If the reduced takeoff power setting specified in the airport analysis manual charts is utilized the following limitations exist 1. ) the runways must not be wet or contaminated with snow, slush or ice 2. ) flaps must be set at 17 degrees for takeoff 3. ) it must NOT be the first flight of the day Operators that make use of reduced power Takeoffs must establish a means to periodically check the availability of static Takeoff power, so that the use of deteriorating engines will not occur. The procedure established by Great Lakes Aviation is to use Full Power Takeoffs on the first flight of the day

Answer 20

20 Seconds on ........... 30 Seconds off 20 Seconds on ............ 60 Seconds off 20 Seconds on ............ 5 minutes off If ignition occurs within 20 seconds of any start attempt there is no limit on the time the starter is engaged for the start For restarts following normal start: 3 minutes cool down beginning when the starter is turned off For continuous motoring without attempting to start the engine: Starter is limited to 20 seconds on, 5 minutes off, repeat as required

Answer 21

Do not conduct static operations in ground fine when the OAT exceeds 38 degrees C

Answer 22

Ground operation prohibited range

Answer 23

Normal Operating range

Answer 24

``` 1700 rpm (1550 rpm GLA) Cruise 1400 rpm if dictated by maintenance/dispatch for gear down ferry ```

Answer 25

``` 1640 rpm (takeoff) When operating in very hot weather high oil temperature may cause propeller rpm droop. RPM droop during takeoff roll to no lower than 1640 rpm, is acceptable provided oil temperatures are at or above 85 degrees C ```

Answer 26

(20 sec. Max) 1870 rpm Sustained propeller over speeds faster than 1700 rpm indicate failure of primary governor flight may be continued at propeller over speeds up to -802 rpm provided torque is limited to 3538 ft-lbs sustained propeller over speeds of above 1802 rpm indicate failure of both the primary and secondary governor

Answer 27

Red arcs - ground operation prohibited range Green arcs - normal operating range Cruise climb and cruise - 1700 rpm (1550 rpm) - May be 1400 for gear down ferry (directed by mx or dx) Minimum droop - 1640 rpm - very hot wx and high oil temp causes minimum droop Max reverse - 1650 rpm Transient (20 sec max) - 1870 rpm - sustained prop speeds faster than 1700 rpm indicates primary prop governor failure Flight Can be up to 1802 rpm if torque is limited to 3538 ft lbs Above 1802 rpm indicates dual governor failure

Answer 28

The propeller auto feather must be armed during takeoff, climb, approach, and landing

Answer 29

Green arc - normal operating range

Answer 30

Max. Usable - 4,484 lbs (665.4 gal.) Max. usable (main) - 1,621 lbs. (240.5 gal) Max. Usable (aux) - 621 lbs (92.2 gal) - fuel in aux must be used first, except in the event of aux transfer failure Max. Imbalance - 200 lbs. Takeoffs with fuel quantity in yellow arcs are prohibited ( 0-363 lbs)

Answer 31

138 Knots (decrease by 2 knots per 5,000')

Answer 32

128 Knots (decrease 2 knots per 5,000 feet)

Answer 33

Crew must contact dispatch before using any othe type of fuel other than jet a/a1

Answer 34

-40 degrees Celsius
