I didnβt find a topic with the exact answer to my question. On a flight from Guarulhos to Paris I had a fuel problem. the well-known dry break. however I had added the necessary autonomy and another 4 to 6 hours of alternative flight. Upon arriving in European continent still over. Ocean the aircraft ran out of fuelβ¦π
What aircraft? Did you plan your fuel correctly?
Could you have left flaps or gear down perhaps? I know it sounds stupid, but you do enough flights and it happens, and that can obviously cause a lot of drag. Unless you got some ungodly winds, 4-6 hours on top of your expected flight time should be more than enough, so either a miscalculation occurred somewhere, or what I mentioned above, I agree with you that at the surface the math doesnβt add up hereβ¦
Yes, yes FLIGHT. Planoβ¦
What aircraft?
Aware!!! Thanks
B777-300!!! Boeing!
Try to fly below 35,000 ft with speed M.78 - 80
Well the only outcome I can think of is if you did a fuel dump or just simply made a pilot error and didnβt load enough fuel even though you said you did. If you did load with an extra 6 hours I donβt think a headwind would affect it that much to make you run out of fuel.
Did you cruise at an appropriate speed and cruise at an appropriate altitude?
Yes MACH.0.86
nonono! Thatβs way to fast try M.80-83 donβt go max speed of M.87 or 86 because thatβs bad .
The plane can stall if it hits strong STRONG winds.
Yes, levei 35.000 mach0.86
Ok? π€·π»ββοΈ Try that!
Okay! Thanks my friend
Iβve never heard of someone stalling because there Mach speed was too high π€
I used to go .86 all the time, donβt worry about it, itβs not the safest, or most fuel efficient, but Iβd be willing to bet that itβs not solely responsible for your fuel exhaustion. Maybe combined with a bad altitude, and terrible winds, and bad trim, and a longer than nessary flight plan, but not on its ownβ¦
before any flight I check the weather conditions that I will face.
Well it does make sense. I also never heard of someone stalling by flying too fast. But if you think about it, it can happen. As you fly faster, the critical angle of attack value decreases, if severe turbulence hits you, and the autopilot pulls up too much, it could lead to a stall. I donβt know, thatβs what I think.
Okay! Aware!
Iβm not sure about that, you can run into problems going to fast, but stalling is not one of them. More airspeed never made someone stallβ¦
I think there might have been some error in your initial flight planning combined with some other condition such as leaving flaps or spoilers extended. Also, itβs unnecessary to carry 4-6 hours of extra fuel. Airliners usually carry about 45 minutes of fuel plus enough fuel to an alternate and a contingency reserve. The weight of the extra fuel itself will increase your consumption. Your FL350 and M0.86 sounds okay but then again it depends on your weight. I suggest you use simbrief.com for flight planning to obtain your fuel load, altitude and speeds.
