Robinson R66 Helicopter in Production

Friday, February 26th, 2010

Congrats to Frank Robinson on his new helicopter product, the Turbine R66, for $770,000 with standard equipment.

His R44 piston was so economical that Bell shutdown production of the Jetranger line, and the R66 is another amazing machine.

And manufactured in the USA.

GPS Maintenance and RAIM Check Workload

Friday, September 25th, 2009

There are two recent changes regarding IFR GPS operations and pilot responsibility in the USA:

  1. Updating a permanently installed GPS database for IFR navigation is considered preventive maintenance and must be performed and logged somewhere, similar to a VOR check, by the appropriate person, plus an operational check. See 14.43 Appendix A (32).
    Only under Part 91, if no special tools or assembly is required, can just anybody can do it. Otherwise a technician must do it the update for operation under Part 121, 135, etc. See this article for more details.
  2. Starting Sept. 28, 2009, preflight RAIM checks for non-WAAS GPS receivers are required for many GPS RNAV procedures, and likely also for WAAS receivers in areas of non-WAAS coverage.
    Pilots have reported having to print a list of RAIM data as thick as a book with their FSS briefing now.

Makes life more difficult than “kick the tires, light the fires and follow the magenta line.” :)

Long Weekend in Hawaii

Monday, May 25th, 2009

I had a relaxing long weekend in Honolulu. It’s nice to have a change of scenery periodically.

It was fairly quiet in Waikiki, as Japanese tourists are still afraid of the swine flu and mainland Americans do the “staycation”. Both the flight on Hawaiian Airlines and the room at the Continental Surf Hotel were quite inexpensive.

I went on a short airplane flight with a female instructor at Flight School Hawaii in a Cessna 172SP.

Blue skies, Kona winds, practise area, a couple landings at Kalaeloa Airport (formerly called Barbers Point), back to HNL 22L.

The 172SP was beautiful except for 1 interesting problem. The magnetic compass had leaked into the Garmin 430 GPS, ruining most of the LCD display. D’oh!

Otherwise I hung out in the hotel or walked on Waikiki beach (quite humid even at night.)

The huge abandoned CompUSA superstore on Ala Moana is still empty, 2 years later.

Duke’s Waikiki was 100% full at dinner time, prolly the only crowded place I saw.

The street performers were even more varied than last time. I hadn’t seen the steel drums performer or magician before.

The Continental Surf Hotel is pretty basic. It has medium-sized rooms with AC and basic cable, coin laundry, a cursory gym (3 cardio machines and a universal machine, no free weights, in a too-small room), and a jumbo flat screen TV in the lobby tuned to a sports channel. Some people rent rooms monthly. There are only 2 small elevators, so if one broke, that could be a problem. Nice view on the roof of Waikiki and Diamondhead.

Fascinating Article on Robinson Helicopters and R66

Saturday, March 7th, 2009

Fascinating article on Robinson Helicopters, its struggles during the recession, and its hopes for their first turbine-powered helicopter, the Robinson R66.

I had a chance to see the tiny Rolls-Royce R330 engine at AOPA Expo last year, which is rated at about 300 HP.

A new R44 is about $500,000, while the R66 is expected to be about $1 million.

I wonder if their decline in sales is due to potential buyers waiting for the R66 to be available.

Robinson has been so successful in the past few years that Bell Helicopter dropped the 206 Jetranger after making it for 40 years. The R44 is about 1/3 the price of the 206, and costs 1/3 as much to operate.

Like Aviation? AOPA Needs Your Support

Monday, February 2nd, 2009

AOPA LogoIf you’re a pilot, plan to be a pilot, or just like airplanes, then join the AOPA or renew today. The AOPA promotes aviation and protects flying privileges.

The United States government is planning to regulate small airports the same as those that serve scheduled airliners, including pilot and passenger scrutiny and onerous inspections, with a program called the Large Airport Security Program (LASP).

If LASP passes, the freedom that GA pilots have historically had in the USA will be a memory, as it already is in Europe.

What can you do?

Could Flight 1549 Have Landed at La Guardia instead of in the Hudson River?

Monday, January 26th, 2009

Update: Video Re-enactment by Scene Systems.

It will take a year for the NTSB to do a full investigation of Flight 1549, and I’m sure many recommendations will be made about airport birds, ditching airliners and things we haven’t even thought of yet.

In the meantime, so far I’ve heard about 5 issues to ponder …

1) After looking at a few Google maps overlayed with Flightaware data for Flight 1549 that landed in the Hudson River, maybe it could have landed back at La Guardia, instead of in an icy river, if landing gear could be extended:


Flight 1549 Ground Track
Flight 1549 Ground Track Google Mashup by Avweb

Another “Powered by Google” Map
FlightAware Live Flight Track Log (AWE1549)

La Guardia’s elevation is about 21′. The engines failed at about 3,200′. The best glide ratio for an airliner is between 12 and 20 to 1, depending on model and configuration.

It looks like range was not a problem, although one would have to look at a current New York sectional map to see what obstructions would be in various flight paths.

KLGA Sectional Chart ApproximationAccording to the sectional I found online, turning right after engine failure would have resulted in no obstructions.

ATC instructed the plane to turn left and the plane complied. I have a feeling from reading and listening to the transcript that more urgency doing a turnback would have resulted in a landing at LGA, if landing gear could be extended.

2) Dick Rutan made the following observation in a letter to avweb.com: “[All the major news outlets] missed the big story that there were not enough rafts. Remember the Titanic. Had this not been in the river, 80% of passengers would have died in the cold water. How many rafts? Enough for all the passengers? There were a few on a raft and the rest on the wing.”

I have heard that rafts have been removed from many airliners to save weight, hence fuel and operating costs.

3) Also, a news report on the web said the A320 “ditch switch” had not been activated, thus allowing more water than necessary to enter the plane.

4) Would it be possible to shroud the engines with a 1 cm grille with sharpened facing dividers to cube the incoming birds?

5) How does a complete engine failure due to birds on a twin affect ETOPS operations over an ocean? Could the engines be damaged on take-off, then suddenly fail at altitude?

METAR weather observations around that time (the event happened on Jan. 15, 2009 at 3:30 pm EST, which is 2030Z) are available for KJFK and KLGA.

Moore’s Law and Glass Panel Avionics

Sunday, January 25th, 2009

As LCD and GPS display technologies get further commoditized in the consumer display and mapping markets, those technologies are trickling down to the aviation world in the form of lower-cost, higher-capability avionics displays – now including synthetic vision..

10 years ago, glass panels were only available in airliners and cost $2+ million.

Last year, Cirrus and Cessna trainers offered glass panels for about $100,000, included in the price of a new plane.

In 2009, a glass panel is now $10,000 for experimental and LSA (under 1,320 pounds) aircraft:
avweb.com: Garmin Displays Non-Certified Glass


Garmin GDU375

We’re now at the point where installing the glass panel, testing and doing the Form 337 for IFR will cost more than the equipment does.

Just as with notebook computers, it will be cheaper to replace an avionics display than to troubleshoot and fix it.

One mfg. is actually selling a glass panel version of their aircraft for $10,000 less than a round-gauge model:
avweb.com: Gobosh Discounts Glass

It seems like the Avidyne MFDs have a poor MTBF and maintenance turnaround time record, while Garmins are both reliable and well-supported. Eclipse blamed Avidyne for their slow FAA certification time, and Cirrus has switched to Garmin recently.

One disadvantage of glass panels in general is that navaid, terrain and weather data updates can be $1,300/year or more, plus the regular cost of paper charts. Also, some avionics will not allow display of outdated data, making them less useful in case of an emergency.

Adding synthetic terrain can cost $10,000.

From a technology standpoint glass panel progress is amazing. From an airmanship standpoint, not so much…

Pilots are likely to spend more time programming their avionics than looking outside the window to “see and avoid”, which needs to be addressed in pilot training courses, and perhaps ratings.

Interesting quote from Frank Robinson …

“The R66 will not be fitted with a glass cockpit, says Robinson: the manufacturer says that this sort of thing would be inappropriate in a VFR machine. ‘I’m not interested in anything that distracts the pilot from keeping his eyes outside the cockpit,’ says Robinson, implying that once such systems could provide everything that a pilot needed at a glance, they would be considered.”

Ironically, Microsoft lays off the whole FlightSim team:

Thanksgiving Weekend Flying in Hawaii

Monday, December 1st, 2008

I spent a 5-day Thanksgiving weekend in Honolulu flying and enjoying Hawaiian Regional Cuisine (HRC).

Cartoon HulaHawaiian Airlines arrived at Honolulu Airport at noon Thursday, so I headed straight to the GA area on Lagoon Drive, ate a Hawaiian-style plate lunch at Hawaiian BBQ, and got a practice flight in right away at George’s Aviation.

Note: theBus’ Lagoon Drive route was cancelled 2 months ago, so you’ll need a rental car or catch a cab on the east side of Lagoon Dr. just south of Nimitz.

I initially flew a 5 year-old Cessna 172SP. This was not a great choice for me to practise for a flight review as the panel instruments (HSI, GPS, etc.) and handling were quite different than my usual 172N choice.

The 172 SP has a fuel-injected 0360 engine with a lot more power, and the airframe is a lot cleaner than a 30-year old N model, so handling in the landing flare is different. (Apparently George bought if from a Fedex captain who kept it as a toy.)

Then I went to my “discount-rate hotel” – the 4-star Waikiki Resort Hotel at Koa and Kauilani Streets – for $89/nite. That’s about half price, so occupancy rates must be really low. (When I was paying for my flight online, a partner popup promoted this deal. I guess I was targeted very effectively.) :)

After another practise flight the next day, I started my FAA Flight Review.

Every 24 months, a flight review by a CFI is required. It used to be called a Biennial Flight Review (BFR), but I understand it may become an annual requirement, hence the recent renaming to just “Flight Review.”

CFI Bob gave me a 1 hour flight review oral quiz. Mostly it involved demonstrating detailed knowledge of airspace on a sectional chart, and explaining the various FARs about pilot and aircraft currency.

After that we did a one-hour flight out of Honolulu Class B airspace to the Wheeler south practise area for private pilot maneuvers, followed by some landings at Kaleiloa Class D airport, and return for landing at HNL.

It was a challenging flight. The winds changed from quite calm for Hawaii using Tradewind procedures to Kona wind procedures mid-flight, resulting in runway changes at both airports. Also, Honolulu Approach frequency was busy for almost 5 minutes, so I had to circle outside the Class B before landing.

It appears the standard North Arrival at 1500′ has been changed to the North2 Arrival at 2000′, effective in the new Airport and Facility Guide (AFD).

I ate the buffet at Sheraton Princess Kaiulani one nite, and another nite had the Pear salad and Linguini Seafood at Sergio’s Italian (yelp reviews) in the location formerly occupied by Sam Choy’s near the Honolulu Zoo.

The city block-sized Compusa near downtown was closed due to bankruptcy, and most of the retail stores on the first level of Ala Moana were new to me since the last trip.

The hotel TV had some interesting items. The Subway $5 ad had one hilarious version with 3 hula dancers doing a hula to the ad song. There was a well-researched hour-long documentary on the history of the UFC, including interviews with the original creators and current owners and president. Plus lots of local news coverage of the Hawaiian airline industry court battles over the bankrupt Aloha airlines trademark.

The shuttle bus back to the airport was only $9, and left plenty of time to eat at the Lahaina Chicken location. The roast chicken and beef combo platter was really good.

Next time I’ll take the free airport wiki shuttle out to the mainland gate. It’s too humid to run around outside with luggage. (Any gate higher than 26 is a long walk with luggage.)

Hawaiian Airlines has the most primitive in-flight entertainment systems, but it’s only a 4.5 hour flight, so I didn’t bother to rent a headset for $5 or a digimedia player for $15. Instead I watched my seatmate cheat on beginner’s crossword puzzles, which was quite amusing.

You Know You’re From Hawaii If…
