Water set to "Landing" not activating?

Is there a reason why the water would not activate when set in Landing mode but would in Takeoff mode? I am practicing in one of the Instant Action missions, and was trying a vertical landing, and had the water set to Landing. No water activated and I hit the ground pretty hard with throttle to full. I was under 20,500 pounds gross weight. But then I tried again, set the water to Takeoff mode, and the water activated just fine.

What's the difference between the modes, and why would it not have activated when in Landing mode?

For TO mode - "Water flows when the throttle is set above 105 percent rpm. After takeoff, water continues to flow until airspeed exceeds 250 knots, water is depleted, OFF is selected, or the throttle is moved below 103 percent rpm".

For LDG mode - "Water flows when airspeed is below 250 knots, jet pipe temperature exceeds 765 °C, and the throttle is set above 105 percent rpm. Water flow stops only if water is depleted, OFF is selected, or the throttle is moved below 103 percent rpm. After initial water flow, water will flow each time the throttle is set above 105 percent rpm, as applicable, regardless of the JPT until the LDG mode datum is reset by cycling the H2O switch".

It does start at 765 C in DCS.

I see, thanks. I was not looking at JPT. I'll see if I can replicate. Maybe just my form was bad - I had assumed that water would assist with propulsion and help my hover if my weight was within limits, but I couldn't maintain a hover and hit the deck kind of hard.

Keep in mind that altitude and air temperature might cause you to not reach the necessary rpm for water to activate.
