I have been flying gliders for a long time and only enter low tow for training to test the students ability to stay in control during aerotow , what I don’t understand is how would low tow be safer . Do you take off and then immediately push down through the prop wash to the low tow position ? 300 AGL is a most critical time due to low level turbulence and height , is this the time to be pushing through propwash to low tow ?
