It's not the exact answer I was waiting for but I consider it as OK.

The answer I was waiting for was:
Extended Twin-engine OPerationS

Horse Powers question

Horse Powers decision, who is right or not.

MD-11 you :rock: Ask your question

MD-11 · Post by **MD-11** » 22 Mar 2005, 10:26

What is the average fuel consumption of a MD-11 during cruise? ( in kgs/hour )
I've changed the question a bit to make it somewhat easier.

hmmm

is it 2462 lb/hr i.e 1116.7 kgs/hr

MD-11 · Post by **MD-11** » 23 Mar 2005, 19:52

Not completely ( this is a hint ) correct, but you're close to the answer.
Read the question once more, especially the part between ( ) and then you'll know perhaps what I mean.

MD-11 · Post by **MD-11** » 24 Mar 2005, 13:30

Is my question too difficult?

Alistairbastian was getting close.

If the members would like another hint, then ask for it.
But then it becomes perhaps too easy.

This seems quite low to me. I have the figure for the DC10-30: 10,400 litres per hour. MD-11 should be lower than that. Since A1 fuel weighs 0.79 kg/l, it should mean some 8,112 kg/hr for the DC10. Slightly lower for the MD11: ~8,000 kg/hr?

Post by **sn26567** » 24 Mar 2005, 14:47

I have even better data from http://md11.info:

- Fuel consumption at Takeoff: 60,000 lbs. (=27,216 kg) per hour
- Fuel consumption at Cruise: 18,000 lbs. (=8,165 kg) per hour

I'll take this as a correct answer, André.
When we flew to AUA our fuel flow was +/-7500 kgs/hr
This is also what I found here

So it's your turn André

OK, a tough one.

The registration of German planes is in the format D-xxxx

Which characters (letters or digits) can be used for each of the four x positions? I need four answers, one for each x position.

And an additional question for the highly knowledgeable readers of Luchtzak: the first x position serves to distinguish between different types of aircraft. Please give the type of aircraft corresponding to each character.

.

The customer code in a Boeing model refers to the airline which originally purchased the jet.
For Example: The 777-247/ADV would mean

777 -> Aircraft Model.
2 -> Model Series.
47-> Customer Code.
ADV -> Advanced or Extended Range or Cargo/Freighter.

Airbus model numbers include a code for the jet's engine manufacturer. They are: 0 - GE; 1 - CFM; 2 - Pratt & Whitney; 3 - IAE; and 4 - Rolls-Royce. And an example could be,A340-313X

A340 -> Aircraft Model.
3 -> Model Series.
1 -> Engine Manufacturer.
3 -> Model Subtype.
X -> Extended Range.

Germany - D-AIGU Lufthansa Airbus A340. So that would mean "GU" on the Lufthansa tail is the fleet number. Also note that in Germany many fleet numbers are simply the last two letters of the registration as in the Lufthansa example.

Now the detailed answer for the benefit of everybody

because Aviation :rock:

The rules for registration numbers of aircrafts in Germany have to be divided into 3 time frames:

Pre-1945 - Germany (Deutschland, Deutsches Reich, etc.)
1945 - 1990 - German Republics
1955 - 1990 - West Germany (Bundesrepublik Deutschland)
1952 - 1990 - East Germany (Deutsche Demokratische Republik, DDR)
1952 - 1956 (International Prefix DDR)
1956 - 1981 (International Prefix DM)
1981 - 1990 (International Prefix DDR)
1990 onwards - Germany (Bundesrepublik Deutschland)

This description covers time frames post-W.W.II (West) Germany

D-XXXX

1) D (international prefix: D)
2) - (dash, sometimes omitted, usually not)
3) character (0 to 9 or A - C, E - I, K - M, O)
4) character (0 to 9 or A - Z)
5) character (0 to 9 or A - Z)
6) character (0 to 9 or A - Z)
Min.: D-0001 & Max.: D-OZZZ

Explanation
1) International Prefix: D (for Deutschland)

2) Separator: The dash (-) as Seperator of Prefix and Registration is usually displayed.

3-6) Registration: 4 characters, allowed are digits (0 - 9) and letters (A - Z).

The registration can be split into two main categories: numeric: 4 digits (D-0001 to D9999)
for

sailplanes/glider have registrations of this form;
the block 9500 to 9999 was reserved for some semi-military, government owned, aircraft during the 1960s;
letter: (4 letters D-xAAA - D-xZZZ), where x stands for one of the following aircraft type categories:
A - multi-engine, MTOW >20,000 kg,
B - multi-engine, MTOM >14,000 kg - 20,000 kg,
C - multi-engine, MTOW >5,700 kg - 14,000 kg,
E - single-engine, MTOW <=2,000 kg,
F - single-engine, MTOW >2,000 kg - 5,700 kg,
G - multi-engine, MTOW <=2,000 kg,
H - all rotory-wing, (Hubschrauber = helicopter)
I - multi-engine, MTOW >2,000 kg - 5,700 kg,
K - all powered gliders,
L - all airships, (Luftschiff = airship)
M - all ultra lights, (UL)
O - all manned free balloons,
the categories D, J, N, P - Z are not used (at this time).

Summary: D- plus 4 characters; either 4 digits (for sailplanes/glider) or 4 letters; if letter, the first letter depicts aircraft type category; some military/prototype aircraft were registered in the D-9500 to D-9999 series during the 1960s; no other rules exist, concerning:
special purpose/prototype/evaluation,location.

8) Hope im right!

Thank you for the compliment 8) Andre.

My Question.

A leading aircraft manufacturer

had promised a model

to an airline

in the early 70's. Since the manufacturer had time against him, work on that particular model progressed at great speed and people associated with that project were called THE INCREDIBLES

Please name the aircraft manufacturer

Please name the aircraft model

Please name the airline

I have really no idea! Since the date matches, I will say the Boeing B747-100 who was ordered first by Pan American Airways (PAN AM).

Seb.

It is Seb's turn now

HorsePower · Post by **HorsePower** » 26 Mar 2005, 10:52

Well, I would like you to give the name of the aircraft, the crew and the date of the first ever flight around the world without refuelling.
