hello ,

could you please explain to me the second step ?

One Engine Inoperative Landing <>

 

1- Plan a flaps 15 landing.

2- Set VREF 15 or VREF ICE.

                If any of the following conditions apply, set VREF ICE = VREF 15 + 10 knots:

Engine anti–ice will be used during landing

Wing anti–ice has been used any time

during the flight

Icing conditions were encountered during

the flight and the landing temperature is

below 10° C.

3- Maintain VREF 15 + 5 knots or VREF ICE + 5 knots

minimum on final approach to assure sufficient

maneuver margin and speed for go-around.

 

4- Use engine anti-ice on the operating engine only.

 

regards

It looks like it's saying that if any of those listed conditions are in effect, you'll have to use VREF ICE which is just Vref 15+10.

 

Example, if Vref 15=160 knots, then Vref ICE=170 (160+10).

 

So if any of those listed conditions exist, just fly 170 knots (in the above scenario).

thank you for your answer ,

 

but i still have confusion between Vref 15 and Vref ICE .what is Vref ice ? what is the difference ?

Vref 15 is just approach speed for flaps 15. Vref for ice is approach speed in icing conditions. So if you are landing in icing conditions, you will fly Vref for 15 plus 10 kts. so if vref  for flaps 15 was 150. You would fly 160 and add in your 5 knot additive. so 165 total.

look at the above post.

 

You will use VREF ICE if any of the conditions you listed are present or will be present during the approach.

 

Will you be using engine anti-ice? If yes, you will use VREF ICE.

 

So on and so forth.
