THAI's Sky-High Deal: 45 Dreamliners to Revamp Fleet
Might be a shortage of qualified Thai pilots soon. Maybe let a few foreign pilots fly their wet-leased planes on domestic routes to free up some Thai pilots? -

Electric Vehicles in Thailand
Part 2 of my note on extra care needed for AC systems in an EV. I am still in the learning process as it is a complicated topic. My research is based on reading and watching video's online. Why EVs needs extra care vs ICEVs? ICEV uses a separate radiator to cool off the engine. If AC condenser loop breaks or deteriorates it does not affect the engine. Most EVs use a shared AC condenser and if components in the cooling loop breaks or deteriorates, it can effect the separate or combined cooling loop(s) of battery, power electronics and motor, with consequences e.g. battery overheating during DC charging/driving fast or even battery shut off while driving as a precautionary taken by the BMS. There are a few expensive EV models that do not use a shared condenser, like the Lucid Air. Reactive vs preventive maintenance We often do reactive maintenance of the AC system, if it's not cool enough in the cabin, because it's hard, costly and requires expertise to do AC maintenance. Many EV manufacturers also omit to advise scheduled AC maintenance. However there are a few sources that recommend preventive maintenance: https://voltaic.net.au/protect-your-evs-battery-the-critical-role-of-aircon-servicing/ https://keepincool.com.au/electric-vehicles-ac-system-how-does-it-work/ What are the components | how it can deteriorate | how to prevent issues? Cabin filter, cabin evaporator | dirt & dust | remedy: replace or clean. Cabin filter replacement is part of scheduled maintenance. Heat pump incl. compressor, or compressor only | compressor oil leak, refrigerant leak, compressor oil contaminated by humidity | remedy: check leaks or more noise in engine bay, corrective: replace o rings compressor, replace and refill oil and refrigerant Condenser | dirt, debris, corrosion, leaks | remedy: clean Heat exchanger or liquid to liquid evaporator to other coolant loops of battery, power electronics or motor | corrosion, leak | remedy: use glycol coolant, clean Condenser air inlet | insects sticking to condenser | remedy: add aftermarket insect mesh to prevent bugs enter air inlet. Can be found at Aliexpress for a Chinese EV. Documented maintenance online Note that above maintenance applies to most EVs. However I only found a handful documented AC maintenance on EVs online. I've collected around 20 Youtube video's. This topic is also hardly discussed on reddit. Cleaning condenser: Tesla USA/Australia/Thailand, BYD Atto 3 & MG4 in Thailand Fixing leaks of compression oil & refrigerant: BYD Atto 3 Thailand. When the user goes to the repair shop complaining about not cool enough AC, in 7 out of 10 Atto 3's leaks are found. Fixing battery shut off while driving: MG EP Thailand. Older MG EPs uses compression oil type [PAG] that is not recommended for EVs. When contaminated by humidity due to hot climate, it lowers the electrical insulation of the compressor HV cable, leading to BMS shutting off the battery to prevent further damage and danger. This issue occurs to taxi driven EVs in Bangkok: MG EP, AION ES and MG ZS EV. Average km driven per year by taxi Bangkok is 83k km, and repair shop gives warranty for 6 months after a fix.
