Understand all that which why I posted “at higher precision RNP procedures”. Maybe an FAA/ICAO terminology difference. There are no “INS” STARs is the point. I do manage OpsSpecs for 3 international bizjets. All RNAV STARS in the US are RNAV 1, there is no requirement for GNSS at all to fly these o...Jump to post
I don't think it was a guess. Ops specs and regulations vary from 200 - 220 lbs per pax. Completely accurate, or not, that's how the flight would be planned. In the US FAA new weight and balance standards calculates passengers weights with carryon luggage at 190lbs summer and 195lbs in the winter. ...Jump to post
The primary question was MTOW restrictions for the A359 at JNB. Any idea what that might be? The MTOW is a flight manual limit for that tail, it does not change from airport to airport, the question makes no sense. If the DL A350s are certified for 275 tonnes or 283 tonnes, it remains at the number...Jump to post
It’s properly termed RNAV, or at higher precision RNP procedures. INS in inertial nabigation system which was the primary RNAV in jets. Now, it’s an IRS, inertial reference system and acts as a sensor for the FMS. Not really, RNAV is area navigation, there is no requirement for onboard performance ...Jump to post

It has been quite painstakingly rebutted with some very informed and detailed discussion that DL's A350s struggle on LAX-SYD. It's almost bordering on misinformation now. PR's A350s (278T) operated longer flights (MNL-JFK/YYZ) than LAX-SYD with very similar seat counts to DL. The flights were 16+ho...Jump to post

If I recall correctly, aircraft equipped with INS could not fly published STARs because the INS was not RNAV compliant (excluding more modern INS units like the Litton LTN-92), so how were arrivals into airports flown with the non-RNAV compliant INS? l Aircraft equipped with an INS/IRS could fly RN...Jump to post
Remember a few years ago when some here said the A350 didn't have the legs to fly LAX-SYD for DL? Think it was UA. I don't think anyone questions whether the 359 has the legs for 13 to 14 hour flights I think people's apprehension was whether would it carry a full pax cabin and cargo hold. Looking ...Jump to post
Interesting, what are the chances of either a thrust bump, or a less likely higher speed rated tire?

The A350-900 already has a very high ACN. With only 4 wheels per main wheel gear I'm not sure how much higher the weight can go.

Intentional control movements do not need to mean suicide.

Even if this was deliberate pilot action, I think it was different than Germanwings. In Germanwings, the pilot was able to lock out the other pilot and was alone in the cockpit. He had a gradual steady descent. If MU5735 was deliberate pilot action, it was most likely a struggle in the cockpit. Fir...Jump to post

I agree, The Key quote from ABC News: . The officials who spoke to ABC News point to the plane's flaps not being engaged and landing gear not put down. The near-vertical descent of the plane, they believe, would've required intentional force. Investigators also looked into one of the pilots' person...Jump to post

I’ve noticed that on the Airbus MCDU when calculating the V1, VR and V2 speeds for take off there is nowhere to input the airport QNH, temperature and winds which all effect your take off speeds, how comes the MCDU doesn’t give you this option to input this but it does for when calculating approach...Jump to post

It’s ridiculous when you consider that the 1500 hour rule had no evidence and is limiting the supply of legal pilots, but the age 65 rule is based on scientific evidence on cognitive decline.

I’ve been told by a real pilot, using 26k ‘bump’ thrust, at MTOW, a 737-700 only needs around 2500-3000 ft maximum runway for take off using this flap setting. So why not just use zero flap?
Well, I was only joking. But all jokes aside, I think it’s only US airlines that offer standby seats? I know they don’t do it in Australia anyway. Miss ya flight and she’s an empty seat.

How do you make that estimate? If we talk about passengers and not payload, we could compare this non-stop flight to putting 238 pax in an XLR that would fly 3x 8 hours to get to LHR.
