Re: More grist for the F18 replacement mill..

Another issue nobody is talking about is the age of the RCAF A310 fleet. Those ex-wardair machines are now around 35 years old and must be on the verge of non-viable. I'd say a mixed 737-based fleet order of p8/wedgetail/BBJ would make economic and operational sense. Another plus is commonality with...

Re: More grist for the F18 replacement mill..

While there is no doubt that the hornets need to be replaced, if the government is serious about the arctic, they should be looking at some P8's and a few wedgetails to replace the Auroras as well as a deep water port. Better yet would be a made in canada solution like the BBD Global based surveilla...

Re: Toilets near to Ramp for employees

Pretty safe assumption that this fellow will be on midnights in the hangar for the forseeable future so I'm sure he's got nothing to worry about as long as he can hold it until break time. If it's a medical issue then that's another story...

Re: Watch That Overhead Baggage

That's interesting hypothetical speculation but it sounds a lot like insider trading so highly doubtful anything like that could happen in this day and age.

Re: Sukhoi Superjet on fire Moscow

from the videos it appears they bounced so hard that the gear failed and both wing fuel tanks were breached.Most aircraft have fuse pins at the gear attach points specifically to prevent this type of event. Horrific.

Re: Kelowna Flightcraft DC-10

I agree with above but it's sad that what was once Canada's third largest flight operations department is now just an empty shell. Very difficult to rebuild. KF had some experienced drivers, I wonder where they all ended up.. In 40 years of operations, I only recall one hull loss, the DC3 at Mayne i...

Re: Kelowna Flightcraft DC-10

My guess is KF’s business model of using vintage aircraft with low acquisition cost and high fuel burn did not align with what customers are looking for these days.

I have a stupid question about manual pitch trim on the 737. Is there really a big-ass cable loop from the trim wheel to the stabilizer jack(S)?
Yes there is, and its about a mile long. Design goes back to the 707 and the 727 was the same.

Re: Ethiopian Airlines: 'No survivors' on crashed Boeing 737 max

Perhaps the MAX needed either a revised/enlarged tailplane, or a longer fuselage, to counter the adverse aerodynamic effects of the engine /nacelle combination, but Boeing went for the easy option, artificial aerodynamic enhancement. Not so easy now. This whole situation is possibly resulting from t...

http://avherald.com/h?article=4c534c4a Very detailed report on the incident, please read. Wow. 500 knots IAS, that must be nearly supersonic, speed would have been quickly beyond flap extend speed.Air loads on the stab would have been massive, and they didn't reduce the power from 94%N1 .. but I su...

Re: Ethiopian Airlines: 'No survivors' on crashed Boeing 737 max

MCAS does not override crew electric trim inputs. You can trim the aircraft nose up, but then when you release the trim MCAS activates nose down again and continues to do so until the crew either trims nose up again or disables the trim system. So if for some reason they were unable to manually trim...

Re: Ethiopian Airlines: 'No survivors' on crashed Boeing 737 max

Its being reported that MCAS trims at a faster rate than normal trim, so a one step forward, two steps back scenario. I have also read multiple reports that if the stab is in a severe out of trim condition, manual trim forces become excessive unless the aerodynamic load is relieved by relaxing the e...

Re: Ethiopian Airlines: 'No survivors' on crashed Boeing 737 max

It is very much looking like the ethiopian crew was not able to manually trim the stab nose up due to out of trim aerodynamic forces, which explains why they would have selected the stab trim cut out back to on to attempt to electrically trim up...but MCAS trims down at a faster rate than normal up ...

It sounds like they are reporting that for whatever reason, they experienced uncommanded nose down trim. Preliminary report should be out any day.

Re: 737 max

Good interview but missed one important detail of MCAS. Control wheel stab trim will override MCAS and allow you to trim the nose up. I am not sure what was said in the interview, as I haven't listened to it, but I believe what was said above is not correct either. The control column stab trim swit...
