FalcoGer Posted March 31, 2022 Posted March 31, 2022 (edited) Multiple issues with hot start: - Doppler navigation radar not on - Chaff is armed, but flares are not - Robbie tank has fuel, even when other fuel tanks have space when starting mission with less fuel load - Robbie tank not active when it has fuel - Barrometric pressure always set to 29.92 (in track i didn't change the pressure for the mission, so it is correct) - SAI not set correct - Lights are off, incl anti collision Extra, just because I happened to catch them on the same track: - Broken rotors still shaking wildly, even with engine off [Reported already] - ECS cabin temperature can not be set higher than 90°F - ECS cabin temperature does not adjust to setting. Starts with 78°F in cabin, but thermostat set to 70°F - Hover performance calculation is off - Weird torque fluctuations when adding collective very slowly even with FMC disengaged from collective - Radar altimeter shows off (but is on), button doesn't do anything [Reported already] - Eng Util page shows severe icing with 18°C outside hot_start_not_set_things.trk Edited April 1, 2022 by FalcoGer
bradmick Posted April 1, 2022 Posted April 1, 2022 (edited) 90 is the maximum, 50 is the minimum for ecs temp settings. What temp/pa/gross weight was the aircraft and how did you determine what your predicted hover torque was? the Robbie tank has to be commanded on by the crew, it doesn’t automatically turn on. chaff and flares shouldn’t be armed on the ground, the chaff actually can’t be armed unless GND ORIDE is selected on while on the ground . If you’re in the air, then I’d probably agree if one is armed, both should be armed. Edited April 1, 2022 by bradmick

Starts with 78°F in cabin, but thermostat set to 70°F - Hover performance calculation is off Chaff should not be armed anyway while weight on wheels, it follows the same logic as the Arm/Safe button. This is inaccurate and I would expect to be fixed down the road. Flares shouldn't be armed anyway because these are typically only armed after takeoff, along with the master Arm, Chaff, etc. Sometimes fuelers don't quite get this right in real life either, and load a little in each tank, just pump it out when loading in. Robbie tanks aren't switched on universally, we already clarified this prior. ECS temp can only be set between 50 and 90. This is accurate. The actual ECS can't always achieve the desired temps as requested in real life either. You're sitting in a greenhouse.

Predicted hover torque was from Performance page Robbie tank has to be commanded on yes, but that is part of the startup procedure Chaff is armed on the ground, so that's wrong in any case.

As stated in reply to your previous post on the topic, there is no real-life checklist or DCS quick start manual checklist that this item is part of the start-up procedure. You're making this up.

FalcoGer Posted April 1, 2022 Author Posted April 1, 2022 (edited) What's the point in carrying fuel that's not being used? If you wanna carry fuel around it's probably cheaper to load it into a fuel truck and drive it over. Edited April 1, 2022 by FalcoGer

Just because it isn't pumping prior to takeoff does not mean it won't be used later. I explained this thoroughly to you last week on this topic, and what procedures are actually used and why. If you want to turn it on as part of your start-up procedure, have at it. But saying it should be turned on for an accurate hot-start is in-correct, you're not gonna get around this fact.

bradmick Posted April 1, 2022 Posted April 1, 2022 (edited) It’s absolutely not part of any start up procedure for the Apache. And I’ll add that if I find myself in an aircraft with mains that aren’t full, as the operator of the aircraft I’ll start the Robbie as part of my run up as a technique. If both mains are full, then I’ll wait until after the first fuel check as a technique to start the Robbie. The perf page has been said to be WIP multiple times. That’s why there’s a perf planning document in one of the mini updates for use in the interim. Edited April 1, 2022 by bradmick 1
