The reference to the fuel pointer is in section 12 FUEL of my FCOM. The point at which the pointer turns to amber is when the FUEL IMBALANCE message is displayed. The FCOM doesn't mention a specific value for this but from my three years flying the real airplane as well as the simulator during engine out maneuvers, it takes quite a long time to show up. I've had three of my colleagues here in Dubai look at this and they all agree that the fuel flow is way too high and the message comes on too soon. That's about as much "expert" advice I'm going to burn on this issue... Thanks for the reply Scandi. I'll have a look at the correct place to address my point when I've got some time. Cheers.

Pilotdude, the FUEL IMBALANCE doesn't come show up at 500-700 kg difference. The low tank pointer will show up at 500kg. This sim is amazingly good as it is, I'm just suggesting a small adjustment (I hope) that will make it even more accurate. Zebra, not sure why your condescending tone. This is a great sim and I'm sure PMDG doesn't take any offense to my well intentioned critique.

Hi, I have posted similar posts trying to get the attention of someone in the know at PMDG. The fuel imbalance behavior is definitely not normal. The fuel flow on single engine is way to high and the FUEL IMBALANCE caution is triggered too soon. I think that this is caused by an unusually high fuel flow of the operating engine. By the way, my day job is flying the real T7 and I am amazed at how accurate most of this sim has turned out.

I posted this before but got no response, so hopefully this gets picked up by someone at PMDG that can make this wonderful sim even more accurate! The FUEL IMBALANCE checklist comes up much too soon after an engine out situation. At 500kg imbalance, the low tank pointer shows up correctly, but the FUEL IMBALANCE EICAS caution shouldn't be triggered that soon. The fuel flow during the engine out in take off was around 15000 kg/hr. It takes considerably longer to get this message on the real airplane and the FUEL IMBALANCE checklist very often doesn't even come up during an engine out situation.

Thanks for the response mfrantz. I had setup the fix and saved it with on of the panels that I frequently use. That is why this problem seems to come up everytime. Now, when I try to enter a complex fix, it works and displays correctly as you said! Any answers to points 2 and especially 3? The FUEL IMBALANCE issue is very annoying and takes a lot away from the realism.

Firstly, as a real world T7 pilot, I'd like to say what a fantastic job PMDG did with this simulation. Just like I did with the 744 a few years back, I find the PMDG T7 a great tool in preparing for my proficiency checks. Yes, they're that good! Having said that, a few points came up whilst practicing scenarios. 1) although the fix page allows complex fixes to be created (eg DXB vor radial 300 at 3.2 DME would be DXB300/3.2), the created fix doesn't display as it should ie. DXB-01. Instead there is a blank field where the name of the fix should be. 2) the aircraft rate of deceleration with the speed brakes extended seems a little too slow compared to real life. Especially with the flaps extended, my real life experience is that she will slow down quite quickly! 3) the FUEL IMBALANCE checklist comes up much too soon after an engine out situation. At 500kg imbalance, the low tank pointer shows up correctly, but the FUEL IMBALANCE EICAS caution shouldn't be triggered that soon. The fuel flow during the engine out in take off was around 15000 kg/hr. this seems a bit high, perhaps?
