Journaling Question Speaking of instruments, the ultralights are equipped with vertical speed indicators. "With full power the airplanes can climb at 750 to 1000 feet per minute," says OM pilot Joe Duff, "but the birds can only climb about 100 feet per minute." Getting them up to 4000 feet takes a long time and uses a lot of their energy." How long might it take the birds to climb up to 4000 feet so they can safely clear the mountain ridges on this part of the migration route?
