Review my Mig-21 Landing 1080p@60 fps (short vid)

What do you say? Cool, Fine, Could be better? Where can I improve?

Looked just about perfect to me. didn't see your final touchdown speed. Might have been sliiightly fast but you didn't break anything so not much to complain about. I usually keep it at about 350kmh on approach and it looked like you were more at 400, but that doesn't look like it was a problem.

Looked a bit fast, I try and avoid touching down above 320ish. 350-380 for approach, flare over threshold, airbrake if necessary, and down at 280 is my usual routine. At some airports (Gelendzhik particularly) you really can't afford any extra speed.

I always break things at 350, don't know about you :D

 

I've read that at it's safer to go faster if you don't want to break things :D

[rossmum]

The faster you are, the more likely a tyre will pop, or you'll overshoot the runway, or you'll end up with just enough ground effect (even with those stubby wings) to have to go around. As long as you're close to 300 you're fine, but past 350 is needlessly adding braking distance.

 

As with most things to do with this module, people drastically overstate how difficult the aircraft is to fly. Its low speed handling is excellent, you just need to keep enough power on (80%) to keep the blown flaps running.

- nose wheel brake OFF, should ON, you need to brake; in Kutaisi you don't need a brake parachute if you land at the beginning of the runway and possibly use additional air brakes

- Fuel 1400 liters with 4x AA missiles and a center tank are too heavy, (typically max. 800 liters and 2 missiles)

- approached too high (14 km before the runway 1000 meters high)

- no navigation lights

- no landing lights

- Flaps only in TO conf., Try it with full flaps :-)

- 400 km / h IAS on final are too fast

- 168kn on touchdown is a bit too fast

 

Nice landing despite the mistakes, try again with less fuel and full flaps you will see that it will be better.

^^ Also trim more. The approach glide slope was all over the place.

It really depends on how closely you want to mirror real procedure with regards to things like lights, etc - and flaps are an 'as needed' thing depending on your approach. Ideally, you'll have an approach where full flap is used, but if you're already coming in low, putting out full flap will just make your odds of a safe landing that much less and you're better sticking with T/O. I honestly think a lot of people in DCS, especially those coming from FC3/FBW modules, are trying to run before they can walk by mirroring the official procedure used by pilots with existing training behind them. It might be easier to work the other way - learn to land the plane without breaking it consistently, then work on getting your procedure perfect.

 

I'm a very seat-of-my-pants kinda guy and a PvP cowboy, so I only rarely have any external lights on, my approaches are usually messy, I'm frequently overweight, and I only use flap as needed. Despite this it's extremely rare for me to damage the plane, though of course if DCS simulated actual airframe fatigue over time my maintainers would be chasing me with a pitchfork for knocking hundreds of hours off the airframe by flying it so hard :lol:

I can't see your actions during the actual landing because external view was used. In general it looks like too much speed, too steep, aiming too far down the runway.

 

@2:34 above the road intersection desired altitude is 384' for 2.5° approach remaining 0.89nm to threshold. You were at 574' which is 4.5°.

 

About @2:43 you realized that your approach aimpoint was 1/3 or 1/2 down the runway and pitched down to make it closer. Crossing the threshold was at 20m. Roundout maneuver was late and touchdown was semi-hard.

 

It is probably the case if threshold is crossed so high that a smooth roundout is has a feeling contrary to touching down early enough. If instead threshold is used during approach as aiming point then as transition will carry touchdown point down runway it won't be so distant.
