flaps 15-0 were retracted a little bit too early.


Yes... that was a little early but generally the take-off was fine. Next time try to get 0* flaps until 200 meters or, better, until 170-180 meters.

Do not reduce the thrust below nominal until 450 meters when climbing.

The first half of level flight was good and more or less stable. Next time try to maintain the level flight with deviation +/-10 meters from the required altitude. For this the flight should be more stabilized.

Lost altitude prior to base turn.

Some operation mistakes. Try to avoid gear (and flaps, just in case) extension in turn. For M it should be extended on final after the final turn.

Flaps shoule be extended from 0 to 28* first and then to 45 direclty when descending on GS.

Next time as I mentioned above try to pay attention on getting 0 flaps until 200 meters and stabilized level flight.

I made a video with tushka from 3d cockpit, while i was practising landings.
Check it out Улыбка The landing wasn't perfect but i think it is worth watching

Hi,

Currently my access on youtube is denied, I'll look through it later on. But viewing MSRP records is more convinient in the Flight School than watching video from 3d cockpit. Хитрый

It was just training Улыбка I captured the video to show for some people how interesting flying with tushka is Улыбка

Hello,
I made a flight after a long break
Unfortunately I exceeded 450 km/h. I couldn't retract the gear at 5m because the Joy button got stuck Смех
By the way, in OSC decryptor, does the "RB высота" column means radar altimeter height?

EDIT: I forgot to add these:
Tushka v2.03
Take off weight 80.7 t, MAC 28.6%, temperature: I don't know how to check what temperature is it in FS9 but I use FAIR WEATHER option if it helps Улыбка

The track is excellent!

After landing but before next flight set trimmers to neutral position. Lights РН НЕЙТР (Rudder Neutral) КРЕН НЕЙТР (Bank Neutral) ТАНГ НЕЙТР (Pitch Neutral) on the center pannel are on.

Vr shoud be equal to 230 km/h, you had 221 km/h.

Gear up height is fine.

Climb profile is excellent as well. The mistake was when you started crosswind turn at the height of 152 meters. Climb until 200 meters before start turning.

Vref was 279 km/h. Looks like you decided to correct it a little bit but has changed the thrust too much. You had to reduce it for 0,5% only but you dropped it for 3%. That is the reason for unbalanced flight below 150 meters.

Also you have to switch on ABSU in manual/yoke mode. ABSU always works during the fligght since it help pilot to control and operate the a/c and it is not only for using the autopilot.

Generally, you flight is almost perfect. just get rid of some mistakes I described above.

Thanks Bell Улыбка
here is another attempt. I managed to make a clean config just about at 200 meters.

Hi,

flaps started to move from 28* at 110 meters. You should do it at 120 meters or above.

What was a height of level flight? Based on the record it was 560 meters, need 600.

Keep 600 meters or 2000 feets until interception GS.

Holding off above the runaway caused by late idle thrust setting. It is forbidden to push the yoke in this case beyond the balanced position. You had to freeze the yoke while holding off and push it again right before touchdown for soft landing keeping some lift force after IAS reduced.

Other stages of flight excellent! Хорошо

The barometric height of level flight was 760m but the elevation of my airport is 200m above sea level.
It is interesting about flaps because I started to retract it after callout "120 метров"

760-200=560. Maintain at 800 meters next time for levelling off 600 meters AGL. Or set QFE before take-off.

Hi Beel and excuses to Dumblius


that I interfere, but the radaraltimeter seems to me to indicate while the aircraft is banking more altitude than while level, is this correct Вопрос .

At least I was sometimes disconcerted by a jump in altitude starting a turn.
Besides the radaraltimeter gives erroneous indications over rugged terrain.
There seems to exist also differences between the new electronic altimeter and the old one.
Therefore which altimeter to use in exerc1
Вопрос

Best Regards

Walter

electronic (or barometric), of course. I do not consider figures from radioaltimeter during analysis. Just use numbers from r/altimiter to define flare height.

Hello

Take off weight: 80.7 t, MAC - 28.6% v2.03

I am not very happy with this one but this was made after some flying "holyday" Улыбка

Hello,

Take-off and level flight were fine.

You'd better perform base and final turns at IAS 370-380 km/h but not 400.

Gear were extended at IAS > 400 km/h that is out of operating limit.

Lost height after the final turn but before FAF.

IAS dropped down to 250 km/h on GS due to late thrust correction after flaps were extended to 45*.

Unstabilized flight below decision height.

Generally, the flight was good except final approach due to "flying holidays." I'm waiting for your next attempt.
