V1 Cuts

[juxtapilot]

Hey all,

What exactly is a V1 Cut? I hear the term a lot, and it seems people sometimes have trouble with them. What makes them so difficult?

Thanks!

Over simplified response:

V1= speed at which when an engine fails on takeoff run, you would continue the takeoff.

V1 Cut equals practicing an engine failure at V1 and continue the takeoff. The loss of performance and asymetric thrust from the engine loss makes it a difficult maneuver. That is why its important to practice, practice, practice.

Things that can happen vary from veering off the runway before rotation speed to Vmc roll after lift off. Among other things.

The difficulty of maintaining centerline after a V1 cut and getting and staying airborne - it gets a little easier as you move up in equipment.

light twin trainer - difficult
turboprop - a little easier (a little harder if autofeather doesn't kick in)
turbojet - a little bit easier

just a oversimplified generalization

Extremely oversimplified.
It depends a lot on design and geometry. There are jets that are easy on a V1 cut and others that will eat your lunch.

Okay, thanks for the info.

Just for clarification:

V1 is the speed at which the first action (not decision) must be taken to reject a takeoff due to failure or some other no go item.


Anyone else get like 4534539458390458 memos about the CHQ flight that had to reject because they had an non-responsive elevator at Vr?

On the ATR you need 150lbs of pressure on the rudder or you go bye bye...Im preparing for a quad workout in the sim....
