View Full Version : Configuration Schedule B737-NG

The standard Boeing configuration schedule for the NG has landing gear and flap 15 selected about 1.5 dots below the glide slope and landing flap selected on glide slope capture.

I would classify this as a fairly high drag approach and was wondering what operators are actually doing in the field, particularly for high (2500' +) intercept of the GS.

What seems to work well for a low drag approach?

How do operators deal with speed requirements of 210 KIAS at 10 nm in Sydney for example?

Flaps 10, 190 IAS for long ILS finals.

If you have a radar altimeter, 2000 agl .... gear down, flaps 15, set speed 160 to the marker.

1500 agl flaps 20, 1000 agl flaps 30 set Vref plus additives.

Flare,

The same as the 200-300-500-700.

-250Kts to 13miles- (11-12 DME if below 90Klbs -calm winds assuming under GS. If on GS at 250 all the way in you'll obviously need to duck at an intermediate level to dissipate energy or level off and store some energy for an early configuration)
-Idle power. Flaps to 5 as you near GS. Flaps 5 to 1400-1500 feet then Gear down, Flaps 15 (about 1 dot high on GS -stored energy)
-Approaching 1000 AGL, Flaps 25 and then landing flaps
-Stored energy allows aircraft to settle nicely on GS in idle by 500 AGL on-speed
-Smooth spool at 500 AGl
-If landing for a long rollout to opposite end, Idle reverse to 80 kts and then smooth braking thereafter

Keeps the fuel bills lower, less wear and tear, keeps the neighbors happy, and the passengers almost always comment. So do the Cabin Crew.

Plane Truth,
Excellent post and just the way to fly a 737 to the max (both in comfort/time for the pax and in fuel savings for us).:O

I am sure you meant to include that after landing you would initially select the minimum FOM required reverse thrust level(dependent upon runway conditions) then reduce to reverse idle approaching taxi speed?

See ya on the line

Another idea

250 KIAS on glideslope and 3000' AGL calm winds is just about it for the 737.

If you don't get the gear out right at that you are going to be outside the slot.

Easy gouge for knowing when its too late to configure (failsafe).

7p3i7lot,

Thanks! Of COURSE!!! (What was I thinking???) ;)


Nice to hear from you or anyone from our "home" site. I have been banned from the site for taking issue with the moderator about sniping and flamers. Seems "they" want to keep that as SOP. Truly sad.

See you 'round campus.
