Approach Idle

Featured Replies

Hello, Just noticed today, when I move throttle to idle in approach mode the N1 indicator quickly point to around 25%(which is ground idle) then back to around 38% (which is correct). So the throttle isn't really in the idle position. Is this correct as in the real life? or is a FSX limitation? What I mean is when flaring we can't really be in IDLE position, instead there is a little space in between. Regards,Frank

This is totally normal. The Electric Engine Control System of the 737NG doesn't allow the engines to drop below 38% N1 with the gear down. With the gear up that's about 30%. This is all totally normal. If the airplane was allowing the pilots to move the throttle totally back to idle (20% N1), then there's a high chance you stall upon flare.

Hi mate, So the throttle itself will not actually be on 'idle' like normally on the ground 'idle'?

I believe this is simply how the programmers had to overcome the limitation of FSX. In the plane, you can pull the thrust levers all the way back, and the EEC knows that, "Yes, you want idle, and I will give you (ground, flight, approach) idle." The TLs don't actually go back up a relative position in the plane. There is a dead-band, however.

Hi matt, Thanks for the clear explanation. If I remember correctly, The old Queen has overcame this (certainly not an issue for me).
