Xplane 11 key for speed brake4/10/2024 Most of our flying was fix-fix-fix-cross fix at 10k-fix-fix-vectors. Profile descents always seemed to be fairly reasonable, but where and when I flew the thing, the procedures were not nearly as complex with OPD STARs into every airport, runway specific transitions, more aggressive descent profiles. Open Descent was helpful if you just need to get lower and do it fairly quickly, at least it behaves like a reasonably well-thought-out airplane in that mode, and it doesn't pin the forward FA against the FD door and make everyone think they're about to die, unlike the first time you chop power in the CRJ and descend in SPD HOLD. It's smart enough in managed speed not to go over 250 under 10k. The airplane doesn't like to slow down, so if you have a decent tailwind, you're probably putting out some speed brakes, or floating along between 10-11k while the airplane gradually slows down. In a perfect world, fully managed for as long as possible is preferred for efficiency and to meet any constraints but it's not always appropriate given the realities present in that moment of the flight.īeen a while since I've flown the 'bus as well, but that day is coming back soon.ġ00% on the first part, it hits a decel point, that in my experience is 1000% too late to actually slow down, especially if your CI had you at 320 in the descent. In real world applications, there is no right way to manage the descent. The danger of going to an open descent while on a vertical profile descent (managed descent) is that it cancels out any altitude and speed restrictions and will go to flight idle at the designated speed to the altitude in the altitude preselect window. You may need to help it out with speed brakes. It's been about six years since I flew the 'bus but if I recall correctly, there is a deceleration point that changes the FMS speed target from the planned descent speed to the 250/10000' restriction. I hope my question makes sense at least! Many thanks for any feedback. If 320kts is indicated all the way down to 10,100', the plane would (surely) have to level off pretty sharpish to lose all that airspeed in so short a space of time! (Not 'elegant' IMHO, but what is happening in the X-Plane simulator).ĭo RW pilots descend through FL100 while in DES mode, in fact, or do they prefer OP DES, or even use the V/S dial, along with the SPD selector? (I tend to switch between all three, depending on the current need). Will subsequent waypoints above FL100 all also show 320kts, or will the flight computer have 'graduated' them (i.e. do pilots use DES mode, and if so, does the speed in the FMC show a decrease as the waypoints get closer to FL100, slowing the plane? In other words, maybe a waypoint in the FMC at FL180 will indicate a managed speed of 320kts. I'm wondering about what really happens on descent through FL100 (and reduction to <250kts). Can any RW pilots perhaps help me (a 'seasoned' Microsoft/X-Plane pilot with over 10,000 hours in the a319/320/321! ) with this?
