# DHC-6 Twin Otter
|
|
# small twin turboprop engine commuter aircraft with simulated
|
|
# icing characteristics (entire aircraft iced)
|
|
# This model was developed by Devesh Pokhariyal of the Smart Icing
|
|
# Systems Aerodynamics group (Prof. Michael Bragg, head) at the
|
|
# University of Illinois. The aircraft data is from:

|
# Pokhariyal, Devesh and Merret, Jason. FDC flight simulator
|
|
# Twin Otter input file (version5_bat), 5/23/00.
