B. Test Leading Edge Flaps and Slats
(1)
Place flap control lever in FLAP UP detent position.
(a)
Check that each flap and slat is in UP position and faired with wing structure.
(b)
Check that all leading edge flap lights on center instrument panel and on aft overhead annunciator panel are extinguished.
(c)
On aft overhead annunciator panel, press TEST switch and check that all green and amber lights illuminate.
(d)
Release TEST switch, all lights shall extinguish.
(e)
Press to test leading edge flap lights on center instrument panel. Check that each light illuminates when pressed and extinguishes when released.
(2)
Modulate hydraulic flow using hydraulic ground interconnect valve so that all leading edge devices will operate slowly.
CAUTION: INTERCONNECT VALVE WILL OVERHEAT AND BE DAMAGED IF ALLOWED TO OPERATE IN THIS CONDITION FOR AN EXTENDED PERIOD OF TIME.
(3)
Position flap control lever in 1-unit detent position.
(a)
As each flap and slat unlocks and starts to extend check that respective amber TRANSIT light on the annunciator panel illuminates.
(b)
Check that amber LE FLAPS TRANSIT light on center instrument panel illuminates when first flap or slat unlocks and starts to extend.
(c)
Check that respective amber light extinguishes and respective green EXT light illuminates as flaps lock in fully extended position and slats lock in intermediate position.
(d)
On center instrument panel, check that amber light extinguishes and green LE FLAPS EXT light illuminates as last flap or slat reaches position.
(4)
Position flap control lever in 5-unit detent.
(a) Check that no change occurs in the position of any leading edge device or indicator illumination.
(5)
Position flap control lever in 10-unit detent.
(a)
As all slats start to extend from intermediate position, check that respective amber TRANSIT light illuminates and respective EXT green light extinguishes.
(b)
Check that respective amber light extinguishes and FULL EXT green light illuminates as slats lock in fully extended position.
(c)
On center instrument panel, check that green LE FLAPS EXT light illuminates as the last slat reaches position.
(6)
Extend trailing edge flaps to 40-unit position and retract to 10-unit position.
(a) Check that no change occur s in the position of any leading edge device or indicator illumination.
(7)
Position flap control lever in 5-unit detent.
(a) Check that respective amber light illuminates as slats start to retract and respective EXT green light illuminates as slats reach intermediate position. 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：737 AMM 飛機維護手冊 飛行操縱 FLIGHT CONTROLS 3(156)
