Mar 20, 2017 · Airbrakes on the Fokker 70's tail section – similar to that found on the BAe 146 / Avro – allows it to conform with the 5.5° glide slope at London City Airport. 2. It allows better speed control. Some aircraft are overpowered with high power-to-weight ratio. The thrust lever range alone won't be enough to hold the approach speed.
Do the four engines of a BAe-146 make it efficient?
Apr 8, 2018 · The BAe 146 had a relatively wide and stubby fuselage, designed for 6-abreast seating but often configured for 5-abreast due to awkward headroom for the window passengers.

What are the differences between air brakes, spoilers and lift …
Nov 2, 2015 · Air brakes increase drag with little change in lift. The following image shows the air brake being used in BAe 146 "Eurowings bae146-300 d-aewb arp" by Adrian Pingstone - Own work. Licensed under Public Domain via Commons. Spoilers both increase drag and reduce lift- basically, they change the lift-to-drag ratio.
How do the uninterrupted and interrupted flaps compare?
Aug 21, 2017 · One data point which shows that interrupting flaps does indeed cost a lot of lift is the comparison of the maximum lift coefficients of an Airbus A320, where the fuselage causes a wide gap between the left and right wing flaps, with the high wing BAe 146 where the gap between the flaps is filled by the fuselage.
