WHATS Vref FOR YOU GUYS

[oncle]

IT'S REF THRESHOLD OR TOUCH DOW WHEEL, AND WHAT YOUR SOP FOR THATS????? AT WHAT SPEED YOU WHEEL SUPPOSE TO TOUCH DOW????

[just curious]

Since Vref is 1.3 X Vso, we generally like to cross the threshold at that speed , retard the power, and rotate the nose up to touch at Vso. Easier on the tires & runway consumption.

[DA900]

Well we approach at Vref +5 with no gust and up to 10kts of steady wind. At wheel touchdown we are at Vref. This being said thats the perfect world. If you flare high you may find yourself below Vref, or if you flare low you may thump it down above Vref.

We add the extra kts. to allow for small fluctuations on the airspeed during the approach. If it is only small increase we bleed it off during the flare. Say it's a gusty day you have up to Vref+15 (our max Vref increase) we will start to bleed it off at 300ft above the rwy as to try and make our touchdown at rwy threshold +1000ft.

I approach at what ever speed blends well with other traffic. 120-160k usually. Target Vref 50 feet over the threshold as per AFM.

What JC said. World standard for wind correction is 1/2 the constant+ all the gust up to Vref+15

[Sulako]

Vref at 50' over the threshold. Throttles go to idle, then a bit o' flare and we have arrived.

If it's gusty, we add 1/2 the gust factor, up to +15 knots max. If the gust factor is over 30 knots, we go somewhere else.

For the Citation 550, this works out to somewhere between 99 - 114 knots (no wind), depending on weight.

rigpiggy: are you telling me that if the winds are 20 knots constant straight down the pipe, that you add 10 knots to Vref? Interesting.

[YYZ_Instructor]

Rigpiggy is right....most standard SOP's in europe,asia and north america are standard as requiring 1/2 the wind plus all of the gust up to a max of 15-20kts. An example would be 040@20G28

With an approach speed of 115kts you would add:

115+10=125+5=130kts Vref
5kts and not 8 kts because up to a max of 15kts.

Appraoch speed at 115 with 040@10G18 you would add:

115+5=120+9=129kts Vref

Depending on SOP's it can vary from company to company.
15-20kts max is usually the case.

All this "fly by numbers" stuff makes me miss airplanes every once in a while.... flying by feel gets old after a while.

Your accent comes out quite clear in your question!!

I love you.

With failng eyesight, I just keep what I think is the A/S indicator in the 5 oclock position unless the nose keeps falling like when you are iced up and then it goes to 6 o'clock and then I watch my co-pilot and when he stiffens up and starts to gurgel. I flair. A Newfie co-pilot is a real help because I don't have to look, just wait till he hollers "Lord Tunderin, Jesus", I then flair vigerously.

200 - 230kts till 4 miles from FAF..... 177kts gear down..... 164 flaps 15....... 130 flaps 40..... Vref 84kts....... gotta love the PC12

[Driving Rain]

Just keep er in the white on the AOA.

[lyncher]

always

[onezerotenthousand]

Good one MAC ! lots of Newfies up here...! (newfoundland north)

200 - 230kts till 4 miles from FAF..... 177kts gear down..... 164 flaps 15....... 130 flaps 40..... Vref 84kts....... gotta love the PC12

Hope the FAF is at least 6 miles from the (controlled) airport!
