Give it 60 seconds to get great. Note to Santa: I would very much like one of these, please.

On November 1st, Toronto Pearson abolished late-night or early morning arrivals and departure for general aviation (meaning non-airline) aircraft. That means we can no longer operate between the hours of 12:30am and 6:30am, under penalty of a fine equivalent to 16x the max landing fee (which is already exorbitant).

We do about 50 company flights a year, and about a third of those are scheduled for departure before 6am - the object of a business trip is usually to fly somewhere far away but arrive in time for a morning meeting. Anyway, Pearson has totally screwed us and I'm sure I will rant more about this at a future date, but for now I will just include this so you are aware it's an additional consideration in my flight planning.

For example, we flew to Quebec City last week to take some people to an evening function there. On the return trip home, we were scheduled to drop off a few of the passengers at a smaller airport before heading back to Pearson for the night.

We figured that in still-air conditions, we would have to be airborne at 10:30pm at the latest in order to land at the smaller airport and drop off some pax and then fly to Pearson and land before the 12:30am cutoff. We told the passengers this, and explained that if we weren't airborne by 10:30 no matter what, we wouldn't be ending up in Pearson that night.

I mentioned still-air conditions. Turns out, the air wasn't still at all. The jetstream was in town, and at 33,000' we had 100 knots on the tail on the way to Quebec City. That meant we got there in just over an hour, but it also meant that it would take us just over 90 minutes to fly the same thing in reverse, which would put us pretty tight on time for getting back into Pearson.

Our passengers showed up at 10:15, and we were airborne at 10:29. At our flight-planned altitude we were estimating an 89-minute flight to the small airport before a roughly 20-minute flight home, giving us 10 minutes to land, taxi in, drop off our passengers then fire up and take off. My previous world-record quick-turn time is 12 minutes, so this was going to be a real challenge, if not impossible.

Have no fear, this is when I get a chance to shine and to show I earn my few bucks an hour salary. I took a page from Star Trek II: Wrath of Khan and decided to think in 3 dimensions, which took a lot of brain power so I made sure I was sitting down first.

A couple of relevant performance figures:

At 33,000', we burn ~1,100 lbs/hour of fuel and cruise at 355 knots true.
At 18,000', we burn ~1,700 lbs/hour of fuel and cruise at 340 knots true.

I decided to eat the additional fuel burn and fly to the small airport at 18,000', where the winds were only 10 knots. We avoided the wicked headwinds upstairs and got there in 70 minutes, saving us 20 minutes of flight time and giving us a decent buffer for landing in Toronto. And on top of that, we even saved money.

We burned more gas per hour, but for less hours. The end result was we burned maybe 200 lbs more fuel than if we had climbed to a higher altitude and flown home at 33,000', but we saved 0.3 flight hours.

For the blog, we'll estimate it costs us roughly twenty-two dollars per minute to operate our jet. A pound of gas costs us about 50 cents. So, I burned about a hundred bucks more worth of fuel by flying low, but as a result I was able to save about four hundred bucks in operating costs. As a flight department manager that's a relevant consideration, so it was nice to be able to save a few bucks in addition to making it home before the curfew.

We arrived to clear skies and calm winds, and touched down 15 minutes before cutoff.

Sliding along the ILS on approach to Teterboro on a recent wet day. My camera's batteries die about 30 seconds from touchdown but I still like the video for showing all the rain across the windshield and for giving you an idea as to the noise level of light rain. When the rain is heavy it can be deafening.

Sometimes the mountains wave.

My Mickey Mouse impression. Please don't sue, Disney.

Don't worry, nothing bad happened - I flew a demo flight for a prospective buyer on someone else's Citation 550. They ended up buying it right after the flight, so I can only assume it was my awesome landing that sealed the deal. Actually, my landing was more like dropping a shopping cart off a sidewalk curb, but maybe the prospective buyer was so impressed that the aircraft held together despite my spine-crunching arrival that he decided to purchase her for her demonstrated resilience in the face of hardship. All airplanes are female, btw.

I have been flying a whole lot lately, and have taken a bunch of video and pics. I'll spend the rest of the day uploading some so I can finally post them.
