PTT, platform transmitter terminal; 8/24 duty cycle, 8 h:24 h on:off cycle for PTT. Other PTTs operated on a continuous transmission cycle.
These columns indicate whether the small attachment (SA) and large attachment (LA) were still present on return.
0=clear (<10% cloud cover), 1=clear with clouds (10-50% cloud cover),2=cloudy with clear patches (50-99% cloud cover), 3=cloudy (apparent 100%cloud cover). If two numbers are given, the first number indicates the cloudiness during the majority of the trip whereas the second number indicates the cloudiness during a minor part of the trip.
If speed is based on a 12 h period, a 56 km h−1 travelling speed was recorded for this bird.
If speed is based on a 10 h period, a 35 km h−1 travelling speed was recorded for this bird.
