All in a flap
'The gross weight of the Archer 111 with power off and full flaps is 45 KIAS. With flaps up this speed is increased by 5 KIAS'.
should read:
'At the gross weight the stalling speed of the Archer 111 with power off and full flaps is 45 KIAS. With flaps up this speed is increased by 5 KIAS'.
thank you for noting the typing error.
