Re: Gulfstream IV FLCH IAS Modes

Taking off and right after lift off at 400 feet, you press FLCH. I see that the A/T PFD FMA center column (throttles column) shows FLCH and the right side of the FMA (vertical mode) shows IAS. The manual shows an 'IAS 'in the throttles column of the FMA but I don't see how you get that to display?

Gulfstream IV FLCH IAS Modes

The GIV avionics manual is a little confusing to me. It says if I press FLCH that IAS will appear in the PFD's FMA (vertical mode) column. When I press FLCH I see FLCH in the FMA, yet the manual talks about IAS as a pitch mode. So, how do you get the IAS mode to display?

Re: GIV Twin Engine Plight Planning Chart

OK, so in this screen shot, landing weight of 50 + 11000 fuel burn == 61000 TOW. Blue line is laid over 61000 and this tells me I can just make it to FL430 but not FL450?

Biz Jets: VNAV and Flight Level Change

Is there ever a time when you would climb out flying a DP, and use VNAV and Flight Level Change together?

I use VNAV to climb out and fly the DP with altitude constraints at each waypoint. If I want to climb straight up to what I have set in my altitude select window, I use Flight Level Change.

Re: MD-90 7,000 fpm rate of climb?

7,000 fpm is on the high side for the MD-90. It would have to be pretty empty (like on a first or early test flight). Typical climb rates at normal loads were more like around 3,000 to 3,500 fpm depending on density altitude. I was an MD-90 instructor for McDonnell Douglas at the Long Beach airport ...

Re: Can anyone identify the flap settings from this video sequence [Boeing 737-200 Combi]

It's hard to say which flap settings were used during the approach. Certainly not all positions are used. So we don't really know if they initially extended to flaps 1 or flaps 2. Very small difference between the two. We also don't really know if they landed with flaps 30 or flaps 40. Love those Bo...
