LNR212 Posted January 24, 2015 Posted January 24, 2015 Hey guys, I hope I haven't missed something, but could anybody please tell the speeds for this absolutely fantastic Jet? For example Rotation, Stallspeed in various configurations, Flaps- and Gear max speeds and so on... Thank you!
Vedexent Posted January 24, 2015 Posted January 24, 2015 I asked the same here: http://forums.eagle.ru/showthread.php?t=137957 I'm working on the following assumptions: Take off: Take-off Rotation: 100 Knts Take-off: 110-120 Knts Gear up: 10m altitude, 150 Knts Flaps up: 160 Knts Lading: 160 Knts/Outer Marker: Gear out, check landing checklist. 130 Knts/Inner Marker: air-brake out flaps down. 120 Knts - sink rate 1 m/s: Touchdown These are all just working assumptions. There may be much better figures for this - but I haven't crashed and died too much using these guidelines.
LNR212 Posted January 24, 2015 Author Posted January 24, 2015 Oh, thank you very much Vedexent! :thumbup:
Vedexent Posted January 27, 2015 Posted January 27, 2015 I'd amend my earlier figures for ILS landing: Speed over the outer marker = 190 Knts Throttle to 82%, hold to ILS glide path. Possible use of speed brakes to slowly drag down your speed. Drop full landing flaps at 160 Knts. You may need to throttle UP after this to hold speed between 130-160 Knts, but don't drop the throttle below 80%-85%. The engine "spool up" time is too long. If you need to punch it up for emergency power, you need it running 80%+ so control with speed brakes. Be CAREFUL - there's an issue with the flight director altitude for ILS. If the flight director, and the indicator on the right side of the HDI disagree, the HDI is right. This is supposed to be fixed with next update, but isn't working now. Drop your speed slowly - you want to be 130 Knts over the inner marker. Inner marker - drop gear, nose up so that your rate of descent is about 500 feet per minute, throttle back to drop speed, but don't drop below 120 Knts. Keep horizontal course pegged on the flight director. Touchdown at 120 Knts - throttle back hard, flaps up to neutral fast, keep speed brakes out, keep her centered on the runway. Let her roll, lightly touching the brakes - she doesn't need tons of roll out room. This seems to work much better.
Tango Posted January 27, 2015 Posted January 27, 2015 FD GS tracking is fixed. Speedbrake remains extended for the entire approach/landing. It increases drag, requiring higher power setting all the way, reducing spool time in the event of go-around and increasing safety. Inner marker is rather late for gear extension. You should extend gear just before glide slope intercept. Best regards, Tango.
Vedexent Posted January 27, 2015 Posted January 27, 2015 Noted :) I know that you fixed the vast majoring of issues, Tango - and quickly too!, wish we had more developers like you in my company :) - but we don't have the fixes yet :) I'm just doing trial and error here. I am generally used to deploying gear with the flaps in other aircraft, but found that the surge in drag and nose ballooning was quite noticeable. I've been working on the assumption that 190 was probably a bit fast to be deploying the gear. Are the gear more rugged than I've been giving them credit for - or am I hitting the glide slope too fast? If I can deploy the gear sooner, then I can still stagger the gear and flap deployment, with the gear coming much earlier.
Tango Posted January 27, 2015 Posted January 27, 2015 (edited) I've been working on the assumption that 190 was probably a bit fast to be deploying the gear.She's a reasonably fast aircraft, but when it comes to limit speeds, think Cessna 152! :D GEAR....WELDED DOWN SPEEDBRAKE...FLAPS EXTENDED THROTTLE...DID YOU NEED TO ASK? Best regards, Tango. Edited January 27, 2015 by Tango
