RotorTalk - HeliflightUK Newsletter
I had some more work published recently in RotorTalk the official newsletter of HeliflightUK Ltd.. They used several of my photos from Western-super-Mare Helidays back in July. I also wrote an article for them comparing model helicopters with flying full-size machines.
You can download the newsletter below, it’s just over 2MB in size so might take a little while.

Ready to throw the whiz-wheel out the window? Have a look at this flight planning spreadsheet that includes the solution to the Triangle of Velocities. With a convenient knee-board sized output and large clear display of all the most important information, you may never need your whiz-wheel again!
Simply enter your desired track, true air speed, wind forecast, and distance on the flight log just as you would with the paper equivalent. The spreadsheet then calculates the heading you require, your ground speed, and your estimated time enroute.
I’ve added a page for different aircraft checklists. At the moment it just contains the startup and shutdown checklist for the Robinson R22 helcopter. I’ll add more as I find them.
I’m in the process of designing a flight planning spreadsheet so that I don’t have to keep doing all the repetitive calculations by hand. One of the calculations involves working out the heading required to maintain the desired track in windy conditions, or in other words, how much you have to turn the aircraft to compensate for the drift caused by the wind. This is usually done using a “flight computer” such as the E-6B, known colloquially as a “whiz wheel”.
But what exactly does the wind side of the whiz-wheel do? How does it work? Before I could add the calculation of the wind-correction-angle and subsequent ground speed to my spreadsheet I first had to derive the solution to the Triangle of Velocities. I thought a page showing the solution here might be useful to the next person trying to solve the problem.
I’ve now updated my helicopter weight and balance spreadsheet to include the Robinson R44. I have maintained the same format for both the R22 and the R44 so that the look, feel, and use is the same for both. The R22 page simply has the rear seats and doors greyed out.
Having spent some time looking on the internet for a good Weight and Balance Calculator for the Robinson R22 Helicopter and finding most of them to be poorly designed and difficult to customise, I decided to create my own.
This MS Excel spreadsheet has a clear layout and simple tables for adding additional aircraft details.
Simply enter your weight, and the weight of your passengers plus their baggage, and the calculator will tell you how much fuel you can load to reach MTOW, and also show you the CG position on the charts taken from the POH. Simple drop-down lists allow you to choose your doors and dual-control configuration, and see how the change in weight affects your CG position. If things start to light up red – you know you’re overloaded!
Western Helidays is a four day Helicopter Fly-in along Weston Sea Front. This years event was held over July 25 to July 27. Helidays is the largest annual event staged on Weston-super-Mare sea front, taking up 3/4 mile of the Beach Lawns at peak holiday season, and attracts all age groups from all walks of life and is not just a specialist “aviation enthusiast” event.
Many helicopters fly in during the event, making up a static display of Military and Civil aircraft, autogyros, and also Military vehicles. Supporting the visiting helicopters are a range of ground displays, entertainment, and stalls along the length of the Beach Lawns. There are also helicopter pleasure flights operating from the beach.
A group of pilots from both Heliflight Gloucester and Heliflight Halfpenny Green flew down for the weekend. A total of four aircraft attended the show – two R22s and one Jetranger from Gloucester, and one R44 from Halfpenny Green. After parking up on the grass and collecting our Air Crew passes we all grabbed a bite to eat and met up in one of the many bars along the sea front. Several drinks and photo opportunities later it was time to head over to our B&B to get changed and ready for a long evening of partying!
The organisers of Helidays put on a free barbecue for all the pilots on the Saturday night after the gates have been closed to the public. Unfortunately we were a little late leaving the B&B and so that will have to remain a pleasure to experience next year. We stopped at a restaurant for dinner, and sampled the delights of various bars until the early hours of the morning. No one got too drunk of course – we had to fly back in the morning!
Sunday morning started with a hearty breakfast, followed by a gentle stroll up and down the beach lawns checking out the other helicopters that were on display. You could quite easily fit an R22 into the back of some of them!
The whole weekend passed very quickly. It was soon time to do an A-check on our aircraft to ensure nothing untoward had happened overnight, then call up Western Information for engine start and begin our journey home.
More photos from the event can be found in the gallery.
