The “Airshow” & “Exhibition”: India Aviation 2014

India Aviation 2014 Apron

Airplanes on display; Modest  display by the small number of international exhibitors; Civil Aviation Minister talks of robustness and reforms; Same ministry’s DGCA is responsible for the delay in Air Asia’s ferry flight.

The photo above shows you how many airplanes were present at the show. There are only two wide bodies, essentially representatives of Boeing and Airbus, and the business-jet-segment representatives of Bombardier and Embraer. Beechcraft, which abandoned the “Hawker” in its earlier name “Hawker-Beechcraft”, after deciding to abandon the jet segment and focus on turboprops, and which was recently bought over by Textron, the parent company of Cessna, had three turboprop representatives at the show, from the Kingair line: B250, B350, and C90. Cessna had its Citation 560XL, Gulfstream brought in its G150 and G650, Bombardier its Challenger 605, Piaggio Aero its Avanti, Embraer its Phenom 100, Legacy 650, and Lineage 1000, Dassault its Falcon 7X, Airbus and Emirates their A380, and Boeing its 787. GMR-APFT, the new Hyderabad based flight school, positioned their Diamond DA-40D fitted with a diesel engine, and the UK based Mark Jefferies Air Shows and Display Aerobatics’ two Extra 330SC and 300L  aircraft.

Few aircraft, including helicopters, did not turn up after the exhibitors decided not to participate in the airshow.

In total? Just 17 civil aircraft present for a country with the world’s second largest population and in a region with phenomenal aviation growth, at the 4th International Exhibition & Conference on Civil Aviation- India Aviation 2014.

Just one order marked the highlight of the day: SpiceJet and Boeing, which had for long dragged the decision to announce the airline’s purchase of 42 Boeing 737 MAX 8s, finally went public with the US$4.4 Billion worth order, pegging the price of each 737 MAX 8 at US$ 104.7M. The 737 MAX’s first flight is scheduled in 2016 with deliveries to customers beginning in 2017. SpiceJet is to receive 17 Boeing 737-800s directly from Boeing, in addition to the order for 737 MAX 8s.

Jet Airways’ order for the Boeing 737 MAX has yet to be announced.

Ajit Singh, Minister for Civil Aviation, stated in his speech at the show, “….is happening at the time when Indian Aviation is witnessing several policy changes and reforms to provide a robust aviation sector.” It is unclear whether the robustness was in reference to protecting existing players (airlines) from competition, or referring to a system that simply does not exist, evidenced by the FAA’s downgrade of the Indian DGCA.

Air Asia India, which was to have ferried its first Airbus A320 to India, today, has postponed the flight by a few days due to certain issues with the DGCA, invalidating the claims of the aviation minister.

The minster also went on to say, ” Civil aviation in India has been scripting a major success story due to progressive policies of the Government”, and that, “commercial fleet size is expected to grow from 400 today to 1000 aircraft by 2020”. There was no reference made to general aviation.

The same progressive Civil Aviation department did not permit few composite airplanes from flying into the show.

Only 26 International Exhibitors are present at the show, most with extremely modest presences.

Edit: Boeing 737 Max unit price corrected; A380 operator corrected.

Peeling away ten Thousand dots, for British Airways’ first A380!

A380, Airways, British

a380_tailThe Airbus A380’s tail is finished separately, and then attached to the unpainted fuselage of the beast. Airbus released photos showing the painted first Airbus A380 for British Airways, and stated that the tail is made of approximately 10,000 individual dots on the tailfin to produce the effect of the Union Flag.

A close observation of the photo to the left (click to enlarge) will reveal that the fuselage is painted (flat finish), but the tail is made from a stencil (dotted finish), with the near-ten thousand dots that had to be peeled off. Unlike other liveries, the British Airways’ Union Flag isn’t made of a flat colour, requiring the stencil, as opposed to a simple paint job.

“Diving” into the A320: Dive Speeds

An apparently “lesser known” fact about the Airbus A320 is the dive speed, its significance, and the associated consequences.

A Flight Crew Bulletin detailing the dive speeds and other speeds above VMO/MMO. (Click to enlarge)

The dive speed is the absolute maximum speed above which the aircraft must not fly. Typically, to achieve this speed, the aircraft must enter a dive (steep descent), as the engines cannot produce sufficient thrust to overcome aerodynamic drag in level flight. At the dive speed, excessive aircraft vibrations develop which put the aircraft structural integrity at stake.

On the Airbus fly by wire aircraft, it is not possible to reach the dive speed, due to the flight envelope protections available in normal law. If the sidestick is maintained full forward, and the airspeed crosses VMO/MMO, the pitch nose-down authority smoothly reduces to zero at approximately VMO +16 / MMO + 0.04. This however, does not guarantee the airspeed stabilizing at this speed.

If MMO + 0.04 / VMO + 20kts is reached or exceeded, then a structural inspection is necessary. Beyond MD (= MMO+0.07) / VD (= VMO + 31kts) (A320 family), structural disintegration can occur.

Here are the speeds for the A320, in Mach number and Kts. The lesser value must always be respected, at all times:

Graphical representation of the speeds, their significance & consequences. HSP is High Speed protection range.

Dive Speeds:

MD/VD = M0.89/381kts

Maximum Operating Speeds:

MMO/VMO = M0.82/350kts.

Expedite Descent (as on FCU, if available)

M0.8/340kts

The graphical representation of speeds above VMO/MMO, on the left (made by The Flying Engineer), gives you a clearer picture of the speeds, their significance for the FBW system, and the consequences.

To understand the seriousness of the VD/MD, take a look at the video below, which involves the VD/MD testing of the Airbus A380. The MD for the A380 is Mach 0.96, and the test crew dread taking the airplane that far.
