VIP Flying

Some of the posts about speed control on descent show a lack of reality, in VIP Flying.. The DCM (don,t come Monday or any other Monday) termination cheque, would be at your last known contact address, pronto.

tmbstory, which posts do you refer to?

Your Kapitan CB puller must have been ex Luftwaffer so he would have had permission to be a prat
Luftwaffe pilots are prats? Let me have a guess, RAF pilots aren`t ?


But no, he wasn´t Luftwaffe, in fact he studied engineering (Dipl-Ing in 'Maschinenbau') and then went on to distribute his fathers wealth in aviation until being broke.
Then he continued to work as a pilot, was involved in the expansion and growth of a local little airline to an LH-Regional partner and then went on to head an air taxi company that now operates something like 8 executive aircraft. He retired but still flies a Jet for a private owner.

He certainly is a character, he is actually a very knowledgeable pilot with tendencies that are....well, not good (such as the overspeed CB thing).

Don't we all have our little shortcomings? But to add to his praise: He recently got his little corporate one-man-show IS-BAO certified all on his own. Something that takes others with quite an organisation behind them a couple of years and several attempts.

And regarding the overspeed CB pulling:
1. Current production Citations don't have this CB any more. They don't even come with the nice little button "Audio to headphones only" that spares the passengers the annoying warning sounds. So no more temptation of overspeeding on approach in modern Citations... not even for our mentor - at least not with passengers aboard

2. We were not talking about overspeeding during cruise (which certainly is a dangerous thing in any jet) but during approach. I doubt, that any straight-wing Citation has engines powerful enough to bring it close to dangerous Mach numbers in dense air. The things are much too draggy. You will burn out the engines long before you break the wings.

3. The low-level overspeed warning of the Citations is not related to aerodynamic or structural considerations, but to the fact, that birdstrike testing of the windscreens was only performed up to 260KT (so I was told during my typerating). This is why the barberpole jumps to 260KT when descending through FL80. Both these figure are totally arbitrary and don't have much practical meaning (do birds really stop flying above FL80? And if they do, would't it be much more dangerous to break the screen in thin air than in thick air?), especially in clouds and at night when there are no large birds around (in my part of the world).

My comments

His Dudeness:

Not yours, I quite agree with your comments on pulling CB,s etc. Thrill seekers are not part of Corporate Aviation or VIP Flying. The people who build the aeroplanes put limitations on their aircraft for a good reason.

The idea of a different standard of flying just because you have passengers or no passengers on board, means you are better off in another Industry. The Pilot in Command is the most important person in the aircraft, If He or She has the safest, most comfortable and pleasant trip between A and B, then everybody behind , also has the same.

Some Corporate Jets in my day would not allow the throttles to be placed in Flight Idle at high level because of a lack of bleed air available to control and stop the cabin altitude from climbing. Flight Idle could be selected at a lower altitude.


Flying requires good sound common sense and nothing less.

Regards

Our CJ2+ has a "Headphones Only" button and it's a 2011 model, so unless this has been incorporated in the last few months you are incorrect!
IIRC, the warnings still will come thru the speakers as well, even if Headphones only is selected. Again, IIRC, thats the case for all FAR/JAR23 Citations.

Since I haven`t flown the CJ2+ for more than a year I stand to be corrected...

My preferred flight profile:

Climb: 300 (250 < 10.000) / .80
Cruise: .84
Descent: .84 / 350 (250 < 10.000)
