Hey guys! I've been trying to take off from Paro airport Bhutan, and for some reason i'm not able to establish enough lift to clear the terrain. I'm configured correctly, and i've shed all the weight that i can by using minimum fuel settings and payload!! It's driving me crazy! both runway 33 and 12 were attempted with no success. I can reach up to 140 knots but then i pull back on the yoke and nothing happens.
The ADIRU is on the hot battery bus, i.e. directly powered from the battery bus bypassing the battery on/off switch. In the case that you turn off your battery switch and "forget" the ADIRU on, the alarm will sound to alert you to the fact that the battery is still supplying current to the ADIRU load - and will likely be depleted by the time you try to power up for your flight back home. This is a common power attachment for critical systems that need to be on when all else fails.
