loosing altitude and crashing

zanettelondon Guest

Hi Guys,
I am having a problem with all the planes I try to fly on FS9, what happens is that when it gets to the cruise altitude, it starts loosing altitude and it crashes, even if the altimeter is set for exemple at 30000ft, it either goes above or bellow the altitude assigned, and then happens what I've described above.

If anyone of you guys cna help me to solve this problem, I really appreciate.

Regards,

If your autopilot is on and your desired altitude dialled in it should keep the aircraft at that altitude.

If you're using accelerated time, this will cause erratic behavior when leveling off from a climb. If you climb at a rate that the aircraft can't maintain climb speed, you will stall and crash. Large jet aircraft often can only climb at 500-1000 FPM above FL300(depending on weight), if they're too heavy, they won't even reach FL 350 and above until they burn off fuel weight. 🙂

Thank you for your reply, but the thing is even with the autopilot on, this thing is still happenning.

Hard to say exactly, you don't give enough specifics. In general, reduce your climb rate, as necessary, to maintain about 300 KIAS up to 28,000 feet. Then climb at Mach .74 up to your final cruise altitude. You may have to level off at an intermediate altitude if your weight won't allow you to climb directly to your chosen altitude. 🙂

Ensure that you are using the AP correctly to set up and maintain your altitude.

What is happening is : When the aircraft reaches the cruise altitude, most of the times I always fly at 32000ft, it starts to loose altitude and then it crashes to the ground, or to goes into a stall situation.

It is happenning with all aircraft I try to fly.Normally above 10000ft I set the auto pilot to the desired altitude, and the climb goes at about 1800ft per minute, untill I reach the altitude requested to the ATC,and the I get to this situation

Sounds like you are setting the AP correctly or you wouldn't get the 1800 FPM VS. Reduce the vertical speed value, as stated above, as you climb and that should work. Less fuel(weight) will also help. 🙂

Do you have pilot heat on?

No sir, I don't have ot on, do you think thi is the reason this things are happenning????

what do you think is a good standar fuel quantity for all aircraft I have, such as b777, b737, b747, MD 11, MD80 and so on

You might try a flight with the heat on if the pilot tube is freezing you do have problems with correct insterment reading.

Impossible to say, each aircraft is different and it depends on distance of flight and altitude. Ball park, for a 737 at FL320 Mach .74, burn is about 6, 600 lbs/hr. Add 1,500 Lbs for T/O and landing, 5000 lbs reserve. So a 3 hr. flight would be about 26,500 lbs of fuel, it will be more for the larger aircraft. 🙂

I just to thank you, the problem was the vertica speed
