Bjorn’s Corner: Flight simulators
By Bjorn Fehrm
22 July 2016, ©. Leeham Co: Last week at the Farnborough Air Show I had the chance to try three flight simulators: The MC-21 airliner simulator, the SAAB Gripen fighter simulator and a special simulator for testing some new 3D synthetic vision ideas for a future avionics system. I’ve now tried some dozen different aircraft simulators of different generations, not counting the PC-based ones.
The simulators were different types. Some were fixed with displays that wrapped around and covered the peripheral vision like the Irkut MC-21 and SAAB Gripen ones. Others were full motion with complete surround vision display like the Airbus A350 simulator that I trained in ahead of flying A350 MSN002 last April, Figure 1. A third type were closed full motion simulators that lacked a vision system.

Compared with the very advanced Airbus simulator, I was surprised how realistic it felt with the simpler fixed simulators I tried last week. It made me wonder why.
Flying the Irkut MC-21 simulator
By Bjorn Fehrm
21July 2016, ©. Leeham Co:Russia’s United Aircraft Irkut division had the good taste to bring a fully functional MC-21 simulator to Farnborough Air Show. I managed to get an hour of take-offs and landings during the show’s early hours on Thursday.
The simulator consists of a fixed cockpit, Figure 1, with a panoramic screen giving a terrain view out of the cockpit windows. The terrain model was of good quality and the feeling of flying a good non-moving simulator was there.

The simulator was especially conceived for exhibitions but it didn’t seem to be less functional because of that. Flight laws should be the same as the full MC-21 simulators but the implementation team is separate from the team which is making the flight crew training simulators. I was accompanied in the Sim by Sergey, one of the software programmers of the simulator. He was interested in my impressions, as it was still relatively early days in the simulator’s design.
Bjorn’s corner: Farnborough week
By Bjorn Fehrm
July 15, 2016, ©. Leeham Co, Farnborough Air Show: We have been at Farnborough Air Show this week, the highlight of the year for an aircraft geek like me. This year there were several interesting aircraft that visited the show for the first time.
Embraer brought over the brand new first prototype of the E-jet 190-E2 and the prototype of their military transporter, the KC-390. Bombardier had their first customer/production CS100 from Swiss to visit the show in addition to their Flight Test Vehicle (FTV) no 5. And Lockheed Martin had the F35B, the vertical landing version, come and hover over the airfield the days that were reasonably rain free in the afternoon.
One thing is clear with the new generation of Single Aisle aircraft: their high bypass engines dominate the visual appearance. Figure 1 shows the 73 inch version of the Pratt & Whitney GTF on the E190-E2 prototype. Huge diameter engine on a not so huge diameter aircraft.

Farnborough Air Show preview: expectations and possible surprises

Introduction
July 4, 2016, © Leeham Co: The Farnborough Air Show begins next Monday and predictably, focus will be on orders.
With new airplanes from Airbus and Boeing past their development stages, conventional wisdom says there won’t be much new in this arena.
Don’t be so sure.
Bombardier is now on an upward trajectory, but don’t look for a big splash at #FIA16 (for those looking for this year’s Twitter handle). Embraer will have its E190-E2 at the show.
It’s Boeing’s 100th Anniversary and the company is rolling out the history for the show.
Summary
- No new products from Airbus.
- Boeing may have a surprise.
- Low number of orders anticipated.
Weekly analyst note synopses
Note: LNC begins today a weekly synopsis of select analyst notes we receive in the previous seven days.
Highlights:
- Delta Air Lines guides down on weaker PRASM.
- Garuda claims it’s now a buyer’s market for new aircraft.
- Interior supplier B/E Aerospace sees a bright future.
- Boeing’s 787 deferred production plans faces challenges
- Irkut is pricing the MC-21 15%-20% under the Airbus A320neo and Boeing 737-8.

yesterday the MC-21-300.
The new airplane is powered by either the Pratt & Whitney GTF or a Russian engine. A report from a Russian-sponsored media site is here.
LNC previously published an analysis of the economics of the MC-21 behind our paywall. We’ve opened up the first of four parts to all readers here.
Can Bombardier extend CS300 to a CS500?

Introduction
April 14, 2016, ©. Leeham Co: Bombardier is working hard to get additional mainline airline customers for its C Series project. The latest discussion is whether Delta Air Lines would replace its fleet of Boeing MD-88s with the C Series.

In this context, it’s also discussed if the largest model, the CS300, Figure 1, is large enough for Delta. This aircraft seats 135 passengers in a two class configuration and up to 160 passengers in an all economy high density version.
The question is whether this is sufficient for Delta and other mainline customers, or if a still larger version is needed in the program, the oft-discussed CS500. We decided to use our proprietary aircraft model to see if a CS500 would be straight forward for Bombardier to develop, should Delta or any other customer ask for a three model C Series program.
Summary
- The C Series aircraft program was developed with the CS300 as the main model. The wing, engine and landing gear were dimensioned with the CS300 in mind.
- The CS100 is a shrink of the CS300, and not vice versa (the CS300 a stretch of the CS100).
- A tentative CS500 stretch if therefore a first stretch of the program’s main model and not a double stretch of a CS100.
- This is evident when one starts to analyze how a CS500 would be designed. There are rather modest changes that need to be done to create an extended model that seat up to 180 passengers.
IRKUT MC-21 analysis, Part 4. Performance with PD-14

Introduction
March. 14, 2016, ©. Leeham Co: In three articles we have been looking at the new Russian single aisle aircraft, Irkut MC-21, from United Aircraft and the new Russian engine that is being developed for the aircraft, the PD-14.
The PD-14, which is offered as an alternative to the base engine for the aircraft, the Pratt & Whtiney PW1400G, was analysed in our Part 3 article. We now mount the engine on the MC-21 and explore the difference in performance compared to the base engine.
Summary:
- The PD-14, which is a new engine designed by the Aviadvigatel company, is a clear step forward for the Russian turbofan industry.
- In our analysis in Part 3, we could see that it has a classical direct drive construction with a good level of technology in several parts.
- Weight and installation dimension are similar to the competition but efficiency is a bit behind.
- We now explore the performance of the MC-21 with the Russian engine.
ISTAT Day 1: Engine updates for CFM, GE, RR and PW
Feb. 29, 2016, (c) Leeham Co.: The LEAP engine, for the Boeing 737 MAX, Airbus 
A320neo and COMAC C919 is the fastest-selling engine in history, says Jean-Paul Ebanga, the president of CFM International. More than 10,000 have been sold.
- We’re at the 2016 ISTAT AGM in Phoenix and will be reporting today and tomorrow on presentations and news from the sidelines.
“It’s on-time and on-spec,” Ebanga said. It’s either been on the date set four years ago or ahead of schedule. The engines delivered to Airbus for the A320neo are on spec, he said. It’s been certified for the neo and will be certified soon for the MAX, with 90% of the information submitted.

Introduction
Feb. 29, 2016, ©. Leeham Co: In two articles we have been looking at the new Russian single-aisle aircraft, Irkut MC-21from United Aircraft. Now it’s time to analyze the new Russian engine, PD-14, which is offered as an alternative to the base engine for the aircraft, the Pratt & Whitney PW1400G. 
Summary:
- The PD-14 is a new engine designed by the Aviadvigatel company, a merger of the Soloviev design bureau with the Perm engine company.
- PD-14 is a modern 31klbf design aimed at several Russian aircraft, the first being the MC-21.
- The technology and performance of the PD-14 engine are approaching its Western counterparts, Pratt & Whitney PW1400G and LEAP-1A, but not quite reaching their level. We go through where it differs. Read more
