I've always thought the A359 was much more capable than the 789, so I've never understood why DL did not place the A359 on this route. Now in a memo posted they are saying the problem has been fixed, but what problem is DL referring to? Prior to COVID-19 SQ used a standard A359 on SIN-SFO-SIN, side note UA 789s SIN-SFO could carry a full passenger load and around 15,000 pounds of cargo. I wish someone could explain what the problem was DL faced with their A359s and how it was fixed.
Could RR and Airbus have 'cracked' two conundrums of great relevance right now, and could DL be the first customer, albeit the quid pro quo being firm orders and deliveries remain firm (or even firmer)?
Two parts of PBTH maintenance, variable and fixed costs. The envelope has been pushed by EK, HiFly and A340 RR operators with Pay As You Go (PAYG) PBTH, with penalties for engine use outside 'life optimising profiles'.
Has RR offered DL PAYG PBTH with penalties AND rewards based on cycles, hours, stage length, reverse thrust, start-up, etc, reducing the fixed component, increasing the customer controllable variable component, and overall potentially reducing total engine costs? Until now, PAYG has rewarded low / intermittent use, whereas this formula rewards / encourages use.
Has it been linked to another 'feature' under discussion with airworthiness authorities, making every TOW the MTOW allowing flight specific de-rates, translating to lower CORSIA values (the initial driver), but also ATC, landing and other charges (COVID), as well as scaleable engine maintenance charges?
Could the finesse of such charging expand A350 viability into A330 territory. If rolled out to the A330, negate or delay the need for a new Boeing model or A322. If offered on the A320 family (unlikely - PW and GE data and PBTH tools are not in the same place), could the A220 be in peril?
Some customers are asking for Pay By The Hour for new aircraft deliveries. For the entire aircraft, not just engines. While commercial aviation is in the doldrums, creative minds are taking commercial aircraft financing to new levels.
