I was flying with the C 172 earlier and it just wouldn’t climb it kept loosing speed, here’s some info
Altitude. 2,500ft (got to 3,000)
Speed. (Didn’t get above 58)
Vs. up to +200 then it stalled
Engine power. Full (87% n1).
Can someone tell me why this is happening, I know the C 172 is a sluggish climber but never this bad.
What was your mixture and trim? Additionally were flaps deployed?
With the C172 I normally start a very shallow climb of 200-600 at the start until I have good speed of around 70-90 knots and then climb. It’s important not to do a steep climb right after takeoff. Remember adjust your VS according to throttle/N1. If you notice your throttle going very high then shallow your climb and find a rate of climb where your throttle is steady.
Well, I think you should be faster than 58ias before trying to climb that high…
Flaps were deployed at first, trim was 30 percent mixture was 80.
Even flat it still didn’t increase in speed.
Yeah I don’t use trim for the 172, also for climb I’d recommend a rich mixture, especially if you are close to stalling.
From what it sounds like, you were climbing too steep with the nose pointed too high from trim and also with a leaner mixture, your engine wasn’t working as hard as it could’ve. I usually use 0 trim or low trim, rich mixture for climb, and as I stated, takeoff and then shallowly climb until you have a higher airspeed and then climb. Also remember to adjust your climb rate to your N1. Hope this helps! :)
You’re roughly 200 pounds from maximum weight. This will limit your rate of climb.
Nevertheless, at maximum weight you still should be able to climb out at 500-700 FPM (depending on the atmospheric conditions) and at 73 IAS. Mixture should be leaned for best performance above 3,000 and flaps retracted.
Ya IRL on a 182 we were 50lbs below the MTOW and got off the ground around the 1,000ft marks.
