DaveRindner Posted February 2, 2015 Posted February 2, 2015 By golly. MIG-21 is the really the 1st AC in DCS where gross weight of AC is actually critical. Especcially on landing. Also on decision on when to return, as this AC uses gas like a V-16 Bugatti at 200mph. So is there a quick glance that tells you what the current GW of AC is at that moment?
lmp Posted February 2, 2015 Posted February 2, 2015 Consider what weapons you have left and how much fuel is there in the tanks. There is a section in the manual discussing it.
ttaylor0024 Posted February 2, 2015 Posted February 2, 2015 With external stores it's recommended to land with no more than 500L of fuel remaining. Without the recommendation is 700L
DaveRindner Posted February 2, 2015 Author Posted February 2, 2015 Perhaps I missed 500L with stores guide for landing. It seems a little light. At 500 thats almost an empty tank, with no go around reserve. I have been landing without gear damage at 320 kph td with 1500L in tank, empty center tank still on pylon, and 2 R-60 on P3&4. With good chute less then 3/4 pf runway is used, and I think I float a little to log for slightly long TD. Its when I think I am running out of rway, and I am still not TD, I try to force td by reducing power or slightly nose fwd. Then I incur gear damage.

In my experiences you have enough for a go around if you need. You can land at higher fuel loads such as 1500, I have as well, however if you touch down with little more than 1m/s descent rate then it's time to repair

The limits in the manual don't tell you what's the maximum weight that you can land and still walk away from it. They're this low because they're designed to limit wear and tear and guarantee (with a hefty margin) a safe landing regardless of whether the airplane your flying is brand new or 20 years old. That said, if you don't care that much for sticking to RL procedures, you should have no problem landing the aircraft with well over 1000 liters and externals stores. I usually try to get the fuel below 1000, so I can land with a bit more grace. After all, burning fuel in the MiG is NOT a problem. Do one extra circuit in afterburner and you've lost plenty :).
