Re: V1 in small twins

The most important sentence in your quote is....... "For a stall speed of less than 61 kts, the climb/descent gradient just needs to be determined (no minimum climb gradient)". This covers a lot of light twins, and is why a lot of manufacturers target a maximum 61 knot stall speed. Be pre...

Re: V1 in small twins

But there may not be runway in front to safely land on. And again, it comes down to knowing the aircraft you fly and having mental gates on actions to be carried out in case of emergency. I guess we are going to have to agree to disagree on this because I am coming at it from a completely different...

Re: V1 in small twins

I agree with pelmet here. Most small piston twins are not certified to be able to handle an engine failure on the ground. Sure, we train for it, but there is no design requirement for them to be able to get airborne, or to maintain altitude with gear and/or flaps down. Takeoff for me is defined unt...

Re: V1 in small twins

One shouldn't even use the term V1 for the type of aircraft the OP stated. There is no V1 for a Navajo, or smaller King Air's. As a blanket statement, this is definitely incorrect. Pelmet, The airplane is certified to fly on one engine and it is even taught on the multi-engine rating. There are no ...

Re: V1 in small twins

There are two speed to be aware of when talking about rejected takeoff (in a multi-engine aircraft). First is what my community calls the minimum go speed. That's the speed at which if an engine fails, a takeoff can still be accomplished. The second is the maximum abort speed. That's the speed at wh...

Re: Commuting, Acclimatization and new Flight Duty Regs

You can easily acclimatize to a new zone by changing your sleeping times as well. Personally even though I live in one time zone if left to days off I go to bed around 2-3 am while my wife goes to bed at 9-10pm. We are essentially acclimatized to 5 ish hours apart even though we live in the same ti...

Not all business related travel is meetings and glad handing. Lifting quarantines won’t end the pain, but it will ease it. I think companies wil...

You are using the same drag polar throughout all the examples or am I missing something?

Re: Needless steep climbouts

There is another, easier way (in my mind) to see the issue (if you are a tiny bit math inclined). Starting from the drag equation: D=0.5*r*V^2*S*Cd Where D is the drag r is the density V is the true airspeed S is the surface area of the aircraft Cd is the drag coefficient Assuming a second order dra...

Re: Needless steep climbouts

well coordinated increase in pitch attitude allowing the airspeed to bleed off to no less than Vx or Vy What I'm talking about is not that, it's a pilot who has chosen to climb more slowly than Vy to begin with. Anything to do with Va, or hundreds of knots is outside the scope of the discussion, as...

Re: Needless steep climbouts

A further reduced drag only strengthens the argument that drag has no bearing on how quickly an airplane decelerate after the engine fails, when compared to an the same aircraft that is straight and level when the engine fails. I'm certainly not a jet pilot, but I don't think this applies to a GA a...

Re: Needless steep climbouts

Drag, whether the aircraft is in a 5 degrees or 45 degrees climb is roughly the same for a given speed (in fact, it will be less in a 45 deg climb but let’s consider them to be roughly the same). What slows you down faster is gravity. AuxBatOn, let’s say an aircraft is in a STEADY STATE climb that ...
