An airplane's horizontal tail is critical to stabilizing the airplane in pitch, trimming out pitching moments caused by the wing and providing control power for maneuverability.
Margins of Safety.
Design process: balance.
Barnaby Wainfan looks at unconventional flight-control configurations in the cockpit and why they can throw even a seasoned pilot.
Critical flutter airspeed.
Columnist Barnaby Wainfan continues his flight-testing discussion by taking up the topic of longitudinal stability. By identifying the origin of the problem, whether it be a control-system issue, a too-small static margin, or a combination of the two, the flight tests he recommends will help to isolate the issue.
Certain situations and configurations just call out for a ducted-fan installation. Barnaby Wainfan explains the benefits and drawbacks.
Cable-operated aileron control system.
Builders are often in a rush to prove the airworthiness of their homebuilt projects, but thorough flight-testing is essential.
