C Series handling quality assessment by Flight International
In the Flight International magazine just released today, is a superb report by Mike Gerzanics of his assessment of the Bombardier C Series handling qualities.
I commend it to anyone interested in a readable comparison of the fly-by-wire systems offered by the various manufacturers. Very interesting, very readable and instructive. https://www.flightglobal.com/news/ar...gh-its-431271/ |
Seems like a fine aircraft.
Surprised, however they didn't go with 'active sidesticks' as Gulfstream did on their new 500 / 600 models. The benefits in overall Pilot awareness with both sticks moving in unison, trim inputs required and built in stick shaker are significant. |
I agree. However, this seems the best of the lot without active feedback.
|
Around the time of the BRJ-X (the CSeries' predecessor) BA carried out a series of tests using both a NASA active stick and one by Sterling IIRC. The cross-cockpit feedback was improved but not sufficiently to warrant the additional complexity and loss of reliability in airline service.
|
I can understand that, but the state of the art in active sidesticks has advanced significantly since then with the BAE product on the Gulfstream.
Too late, perhaps for the C Series, it was in development for a long time. Shame because Gulfstream have come up with a superb solution to the problem of lack of awareness regarding the other Pilots inputs and gives the Pilots valuable feedback into the aircraft's state simultaneously. |
