A rectangular course is flown at 1,000 ft AGL with a wind from 270° at 20 kts. On the DOWNWIND leg (heading 090°), the pilot should

Choices

• use a steep bank when turning to base because groundspeed is high.

  Partial — the steep bank is correct but the timing also matters.

• ✓ begin the turn to base earlier and use a steeper bank than on the upwind leg.correct

  downwind groundspeed is highest and the airplane will travel further during the turn. On a rectangular course downwind leg, the airplane has the highest groundspeed (TAS + tailwind component). When turning to base, the airplane will travel a longer ground distance during the turn, so to maintain the rectangle's corner: BEGIN turn earlier AND use STEEPER bank to compensate for the higher groundspeed. Reverse on the upwind leg: shallower bank, later turn.

• use the same bank angle as upwind because true airspeed is constant.

  Same bank gives different ground tracks at different groundspeeds.

• fly faster downwind to compensate for the tailwind.

  Faster TAS isn't necessary; bank/timing is the correction.
