Multi Engine Approach Q

[Deleted]

OK, question for RW pilots with lots of multi-prop time. When you're doing an approach, are you holding "blue-line" speed all the way to the runway typically? Seems like you'd float most of the way down the runway with that much extra speed. If not, when do you abandon it and start slowing for a normal landing speed (i.e. Vmc + 10 let's say)?

Thanks.

I don't remember a blue line at all. I always held the airplane 10-15 above VMC and bled that off over the grass before the threshold after commitment.

I think that indicates best single engine climb rate (V_{ybestsingleengineclimbrate}). What you are doing sounds pretty much like what I'm doing. V_{ybestsingleengineclimbrate} is often much higher and you have too much speed to lose on short final.

The "blue line" mark on an airspeed indicator for a multi-engine aircraft indicates the speed for best rate of climb with the critical engine inoperative;
When the landing is 'insured' speed can be reduced for landing. In other words if your within 'gliding distance' if both engines quit you don't worry about BROC with..... etc. cause' your gonna land that sucker! On those looong drug in approaches keeping 'blue line' or better will allow you to climb out if it gets 'quite' on one side.

Thanks Spud. That's kind of what I thought. Appreciate the help

Correct, Spud. The problem is ...... I just can't remember! I wish I could find my Aztec book for the real airspeeds. I can only find my Apache book, and the airspeeds are totally different. I do know we did not have a blue line on the a/s indicator; only the usual green, yellow and red with the white flap arc.
