Or would you just use flaps 30 for landing? After all, in real life, those who fly these a/c spend weeks learning how to do it. I would think thrust is thrust. Did it in a 727 once into Philly only because the FE sucked at his job and refused to go to the electric flaps portion of the checklist. (The tower and ground feeds didn't work so well as approach.). The plane was flying from Ahmedabad to Patna as SG 8719 on 5th October when it faced issues with its flaps on approach to its destination, according to The Aviation Herald. Press J to jump to the feed. The reason behind the incident has to do with an issue with the flaps. The 737-800 is in service with a ton of airlines world-wide. Issue with flaps. We will find out more details about this incident in the coming months after a DGCA investigation. In that incident, the aircraft overshot the runway and fell into a valley. Can someone ELI5? Establish final approximately 10 NM from the runway. I can't find it in any of the manuals. My mate who flies the B738 did a 5 deg flap landing due to error messages about slats not deploying. You would need more flaps if the runway is short, with a max of 25 for takeoff and obviously full for landing or if you are really heavy. By Maybe Herehttp://www.b737.org.uk/You can find some stuff.Best Regards,Bert Van Bulck, Tom Allensworth, The aircraft involved in the incident is a 13.6-year-old Boeing 737-800, originally delivered to Jet Airways in March 2007. If you want more lift, you need more flaps, and vice versa. The fact that you did not know this and used the amateurish term 'landing speed' and then did not know about weight dependence and then mentioned "landing speed at sea level" (which has no place in aviation since. Copyright © 2020 | MH Magazine WordPress Theme by MH Themes Chesley B. Flaps failures and consequent no-flap approaches result in high-speed landings due to the higher stall speeds. BOEING 737 - 3/4/500 Landing Flap-Speed Schedule. There are 8 flap settings on the 737-800/900, with each having a different angle. Do not autoland. Found out it was a problem with the sensor. Use a normal aim point approximately 1,000 feet down the runway. We use ads to keep our content free. Touchdown will normally occur at a speed less than target. Picture is mine, use with permission only. Lots of variables go into this including weight of the airplane, weather conditions, type of approach, etc. Are those air speeds or ground speeds? Cookies help us deliver our Services. The average landing speed for a Boeing 737-800 with flaps deployed is about 145 knots, but this can be higher depending on the plane’s weight. Some failures require additional speed on final as well, for instance if flaps are limited to a lower setting. Flight track here, you can see them circling a bit while trying to sort it out. "Sully" Sullenberger: the hero of US Air Flight 1549. I think you can use 1 and 2 for takeoffs at insanely long runways too. This allows time to extend the gear and decelerate to the target speed while in level flight and complete all required checklists. The incident comes just weeks after the DGCA completed its special safety audit of SpiceJet, as a part of its effort to audit all Indian carriers. If a flaps up landing situation were to be encountered in service, the pilot should consider the following​ techniques. Here are the airspeeds in which each setting of flaps should be used to prevent damage, and maximize lift. https://theaviationist.com/2014/01/30/b-737-no-flap-landing And yes, you can go down to ~125KTS on landing. Military is weird like that. Anyone hear what happened? Thank you but I have been flying - REAL flying - since 1952 and I do not appreciate sanctimonious cleverness from ill-mannered airline wannabees. When I descend using the glideslope and A/P the nose is up, almost in a flare position which means when I disengage the A/P the plane isn't in the right position to float onto the runway and I have to correct it just in time otherwise I either hit the runway too fast or have a tail strike due to the planes angle. boeing.com This high speed is likely due to the issue with the flaps, which may have prevented the aircraft from reaching the ideal landing speed. For your information, expressions such as v-ref are relatively new and landing speed was the term generally used in my time. Speedbrakes are not recommended for airspeed reduction below​ 800 feet. At around 6,000 feet, the crew decided that Patna’s runway, at 6,798 feet, would not be long enough to support a high-speed landing. The V speeds inputted into the table should come from official sources (ie Airline Operating Procedures, manufacturer flight manual for the aircraft), Powered by Discourse, best viewed with JavaScript enabled. If this is your first visit, welcome! It's all in the manuals or tutorials...Rgds,Bruno. I was listening to EWR approach on LiveATC last night and heard someone dealing with flaps that wouldn't deploy. Too much fuel can be the reason, so you just have a look and let us know, and for speed brakes, as il88pp mentioned, press Shift+/ to arm it. Thanks, Matt. I arm the speed breaks but they never seem to work on touchdown unless I press the / key myself. It depends on the aircraft weight, runway length, and (for takeoff) desired derate and climb angle. In all the aircraft with which I have been associated you always had a yardstick of a landing speed at sea level/zero wind. Thank you but I have been flying - REAL flying - since 1952 and I do not appreciate sanctimonious cleverness from ill-mannered airline wannabees. The 737-800 is a short to medium haul aircraft made by Boeing Commercial Airplanes. Boeing Commercial Airplanes offers airplanes and services that deliver superior design, efficiency and value to customers around the world. Good place to learn about this and other NG flying techniques is Timothy Metzinger's PMDG 737-NG Advanced Tutorial. Assuming that they would also retract them a little sooner after takeoff too. Flap. Click here for more information and to see all donations year to date. My speedbrakes never seem to work well.. Boeing recommends that the approach speed for 737-800 be 142 knots. Deck angle, speeds? Flaps 5 - 170KTS The main operators of the 737-800 are Ryanair, Southwest, and United. Boeing: Next-Generation 737 To date I tend to reduce speed from 250k to 160k whilst dropping to 25 of flap immediately before picking up the localiser and then reducing to 130 (still with 25 flap) prior to picking up the glideslope. Lets not rely on numbers from other simulators. Do not make a flat approach (shallow glide path angle) or aim for the threshold of the runway. Damage to flaps/gear if max speed exceed. The aircraft seems quite stable but I wonder how far this tallies with the authorised speed.Jim. Slight forward pressure​ on the control column may be needed to achieve touchdown at the desired point and to lower the nose wheels to the runway. Great tutorial, Matt! A SpiceJet 737 diverted to a larger airport for an overspeed landing on Monday after facing flap issues. But with so much nose up I'm in danger of tail strike all the time. Use 5deg nose up for initial flap settings. The approach speed for large commercial aircraft like the B737 will vary depending on weight. Share the result with us! Vref actually does NOT depend on field elevation, The Janitor - An Interview with Tom Allensworth, Interview with Joshua Howard Re MS FLIGHT - March 2012, Interview with LMOC Re P3D - September 2012, The AVSIM Hack - First Published in May, 2009, The AVSIM Hack - The Full Story - Published April 2013. Thanks for reading this, and hopefully we can all become better pilots together! I did two in a day. This issue could have meant the flaps failed to deploy at their required level, forcing the plane to land at a higher speed to prevent a stall during the approach. 4 years ago. Do you guys have the ability to dump fuel? http://krepelka.com/fsweb/learningcenter/aircraft/flightnotesboeing737-800.htm#flaps. Flaps 30 - 130KTS What's that like in a 737? I'm done for now. Flaps 2 - 11° Because as soon as you start manual braking, the Auto Brakes go to disarm position, and maybe that's one of the reason speed brakes go down too. So far as I have been able to ascertain, there is no reference to the question I asked in the manuals and tutorials which seem to be strewn over the net and a sensible ball-park answer would have been helpful.
