I wanted to fly the 747-8 for ultra-long haul because it can store up to 23h44mins of fuel however I have difficulty taking off this plane. Is this considered a near tailstrike? Is it normal in IF and do pilots flying the 747-8 irl also pitch this much till the tail is inches away from the runway?
Here’re my takeoff details:
N1: 100%
Vr: 180kts
Flaps: 20
Fuel weight: 100%, not sure about aircraft load I think it’s above 90% (near MTOW)
Passengers: 20
Cargo: 1004kg front 2008kg back
Hey there!
That doesn’t look like a near tailstrike to me. 100% N1 seems a bit much, usually I don’t put mine above 90% if I can help it.
I have seen planes in real life closer to a tailstrike than that, however.
:)
Completely normal rotation angle
I have to put it at 100% N1 because my airspeed will drop as I’m climbing at 2500-3000fpm. If I put it at 90% to keep my airpseed from falling and eventually stalling my climb rate is limited to 1200-1500fpm which is too slow for initial climb.
Makes sense. :)
@Coolman He is talking about rotation. :)
Yeah, I deleted it 😂
Might sound counterintuitive but unless there was a short runway, I’d use flaps 10, it causes less drag and you can climb at a higher rate
If you wanna see a near tail strike look at this
Edit: less flaps will cause a higher rotation angle
The aoa is high but the climb performance is meh…exactly what I’m experiencing on the 747-8 when fully loaded with fuel.
If I were to use flaps 10 for this weight setting I’d probably had to accelerate to 200+kts to be airborne. The tyres would’ve exploded due to the immense centrifugal force. Even though it won’t happen in IF, I find it unrealistic.
With 20 passengers and 3 tons of cargo I find it hard to believe you’re close to your MTOW. Looks like a nice takeoff to me.
Based on your inputs I guess it’s normal for the 747-8? Because I don’t rotate at such a high angle for other planes like 777 and 787 (both are tested with the same weight 100% fuel and low passengers and cargo)
If you wanna be realistic I’d suggest you reduce your gross weight because is MTOW rarely ever used as an the actual limit. Most of the times there will be performance limitations. That will be significantly more restrictive
Well Let’s see, I’ve flown the B747-8 many times with 60%+ fuel for 12h flights and a Cargo load of 6000kg in the back and 8000kg in the front, 300 PAX.
Have been able to takeoff with 85-90% N1.
Flaps are just like yours 10°
And from the looks of ut your takeoff isn’t a tail strike, it’s pretty beautiful one actually.
