[SP1]Wrong FD during ILS approach

Post by kevinlee251 » Sun Apr 12, 2020 5:40 pm

During the ILS approach I recently tried, there have been several bugs indicating FD errors
If flying according to FD, the aircraft will dive and crash.

It seems you are flying too slow the final approach, still far from the rwy. Best approach speed to maintain a smooth GS is 125-140 KIAS until 1 mile of the rwy threshold or less. The KA uses default P3D ILS commands, just to make all ILS arrivals compatible with the default scenario, and so there is kinda limitation in the range of speeds to be used with the GS path ride.

If approaching at low speeds, the GS indicator might quicly fluctuate between above/below of center, hence affecting the FD needle. In your example, it seems that the diamond is going into above position, pehaps very fast so the FD is commanding a pitch down to counteract that.

Did you fly a NAV to NAV procedure for that approach?

thank you for your reply, yes it is nav to nav , maybe my airspeed low but no lower then Vref+10,Will FD respond to changes in power? Or is it just a gesture guide?
