I did my BFR last month in a PA28-181. It is an airplane new to the
flying club I belong to and although I have more than 60 hours in type, the owner requires anyone who desires to rent it, have an instructor checkout. Prior to the flight I calculated a weight and balance and appropriate speeds for the actual takeoff and landing weights. I started to pull for takeoff at the calculated speed and the instructor said, "No, no, wait until 65 kts." Okay. For the first landing, I stated the calculated 1.5Vso and 1.3Vso speeds. The instructor again said, "No, no, that's too slow. Use 75 kts." When we were on the ground, I asked him why he wanted the faster speeds. His answer was that this was not a new airplane, so the book values needed to be increased to allow for age related things that could affect the noted V-speeds. I can understand the reasoning for a student pilot, the likes of which this instructor does a lot of training with, but I am 1200+ and over 20 years of flying. I am thinking in terms of performance as would apply to the Commercial standards. Hence, the reason for calculating the necessary speeds prior to flight. I will add that flying at the instructor's recommended speeds leads to float in the roundout and required more runway. Flying at the calculated speeds would have resulted in a full stall landing at the threshhold and clearing at the first turnoff. What is the perspective of the instructors in this group? The instructor I fly with knows me. Why would he not hold me to Commercial standards? |

Good landings are slow landings. It is all energy management, and his method
increases the amount of kinetic energy to be dissipated by floating, heating the brakes, or wearing flat spots on the tires. His argument is fallacious. Bob Gardner "EDR" wrote in message ...

I think the instructor's reasoning is faulty. Why would the stall speed
increase as the airplane ages? If it has increased measurably, then something needs to be repaired. I don't even teach student pilots to fly faster than necessary. It is too easy for a student to lose control on a fast approach, especially if he balloons or bounces. |

Richard,
Well then this instructor will be really un-comfortable in my airplane. Final is done at 70-65 MPH (61-56 Knots). Final landing is around 55 MPH (48 knots). ;-) Michelle Richard Kaplan wrote: "EDR" wrote in message .. . What is the perspective of the instructors in this group? What you did was fine.

I started to pull for takeoff at the calculated speed and the instructor said, "No, no, wait until 65 kts." Okay. Why do you want to hold it on the ground that long? I own a '67 PA28-235 and couldn't tell you the actual rotation speed. When it wants to fly, let it fly! I do know it is well below 65Kts though cause I've seen the airspeed pass through it as I'm gaining altitude. For the first landing, I stated the calculated 1.5Vso and 1.3Vso speeds. The instructor again said, "No, no, that's too slow. Use 75 kts." I'd rather 70kts as a rule of thumb. The only advantage this gives you is slightly better control effectiveness, otherwise use what you're comfortable with. When we were on the ground, I asked him why he wanted the faster speeds. His answer was that this was not a new airplane, so the book values needed to be increased to allow for age related things that could affect the noted V-speeds. Puppycock! (And many other expletives as well). Arguments can be made that dirt and grime accumulate and make an airplane heavier. No one considers the fact that radios way back when weighed a heck of a lot more than they do now. I took about 30 lbs. of extraneous crap and wiring out of my plane when I bought it. IMO it's a trade off and his rule is not a good one. How's it Feel at the speed you're flying. If it feels good great, if it doesn't feel good adjust a little bit.

I will add that flying at the instructor's recommended speeds leads to float in the roundout and required more runway. Flying at the calculated speeds would have resulted in a full stall landing at the threshhold and clearing at the first turnoff. If you start your "round out" earlier you can still land on the threshold, but then you'd be going below his required speeds. So, yes listening to him wastes runway needlessly. What is the perspective of the instructors in this group? He's a 141 rat that needs to learn how to fly a wing, and not the airspeed indicator. (I know I'm being hard and don't know the guy, but what you wrote doesn't make sense.) The instructor I fly with knows me. Why would he not hold me to Commercial standards? This is not (yet) required for completion of a BFR. |

Cowardice on the instructor's part. Much of the art of flying requires that our brain rule our emotions. The instructor appears to have surrendered to fear. |

Unless the instructor was joking with you, it might be time for a new instructor. Aircraft age has nothing to do with V speeds. I fly final in my PA28-180 at 80mph, and slow to 75 crossing the threshold. This is right at 1.3Vso, (57*1.3=74) and it works well. |
