The biggest advantage would be that you don't have to remember as many numbersstlcards said:Does anybody know why and what advantage an airplane would have when Vy and Vyse are the same. For example in the Piper Seminole Vy and Vyse are the same speed, 88kts.
SBD said:Just remember, if you lose an engine below Vy or Vyse good luck. Chances that airplane will still climb is about 50/50.

sleddriver71 said:While Vyse may be the most efficient airspeed for rate once established at that airspeed, it is not always the best airspeed to attain in every situation, at least initially. If you are 5 or 10 knots below Vyse and single engine and lest's say 20 feet off the ground, if you pitch down for Vyse, you will most likely make contact with the ground. In this situation, it is better to initially maintain the slower airspeed (pitching up close to Vmc or stall may be required) instead of pitching down to Vyse. Make sure to immediately (in a controlled fashion of course) add max power (keeping controllability in mind), and clean the airplane up (don't forget zero sideslip - usually half a ball deflection and a few degrees of bank towards the operating engine). Be patient and let the airplane slowly accelerate back towards Vyse.
In regards to the chance of the airplane climbing below Vy or Vyse being 50/50, ummm, there is little to no chance involved. Depending on weight, CG, atmospheric conditions, and pilot technique, the airplane will already be in a condition to climb or not climb and it is up to the PIC to know the current conditions as to whether or not it will climb, it's not chance.
