BAC1-11 INITIAL FLIGHT TRIALS
JOHN THORPE FRAeS, FORMER BAC FLIGHT TEST ENGINEER
The April 2017 lecture will describe the background of the “BAC1-11 Initial Flight Trials” project from its Hunting 107 origins leading to a description of some of the innovative features. The sad loss in 1963 of the prototype due to ‘deep stall’ is described along with details of some other deep stall accidents.
Having in 1974, along with three others from Filton, joined the team of flight test observers at Wisley, the speaker will use some of his own photos and experiences to cover:
• stalling and flutter testing,
• airline demonstration flights,
• intensive route proving from Gatwick,
• production testing at Hurn and
• entry into service in April 1965.
The aircraft became known as the ‘Bus Stop Jet’ and was developed to become a best seller in widespread use in over 70 countries. The presentation will conclude with a review of the 1-11 safety record in comparison with other twin-jets from the same era, what might have been, the aircraft’s demise due to noise restrictions, details of the last airworthy 1-11s and where in the UK preserved aircraft are open to the public.
