Precog Posted March 7, 2016 Posted March 7, 2016 Was descending in clear skies last night with the pitot heat off and noticed my airspeed indicator dropped to 50kts. Switch pitot heat on and airspeed indicator returned to normal. Given the right temperature range for icing, pretty sure pitot tube can only block when descending through visible moisture i.e clouds.

Ragtop Posted March 7, 2016 Posted March 7, 2016 Did you check Outside Air Temperature on the CDU POS page? What altitude were you at? A clear sky isn't necessarily a warm one. 476th vFG Alumni
Flamin_Squirrel Posted March 7, 2016 Posted March 7, 2016 A clear sky might not be warm, but if it's dry then there's no moisture to freeze. From what I understand this is a DCS weather engine shortfall, in that it doesn't really calculate icing conditions properly (basing it on temperature and not ambient moisture).
Eddie Posted March 7, 2016 Posted March 7, 2016 Yeah, it's just the way it's modelled in DCS. The visual cloud/fog effects are not in any way linked to icing.
lobo Posted March 7, 2016 Posted March 7, 2016 Nevertheless, if you are in the air pitot heat should be on. Lobo's DCS A-10C Normal Checklist & Quick Reference Handbook current version 8D available here: http://www.digitalcombatsimulator.com/en/files/172905/
Precog Posted March 7, 2016 Author Posted March 7, 2016 Nevertheless, if you are in the air pitot heat should be on. Not in real life...at least in general aviation. My training manual states turn on if below freezing and in cloud Check out my 'real world' video series [sIGPIC][/sIGPIC]
Eddie Posted March 7, 2016 Posted March 7, 2016 Not in real life...at least in general aviation. My training manual states turn on if below freezing and in cloud With military aircraft, if you're airborne, it's on. Many aircraft don't have the option for the pilot to turn it on or off.
Ranbi2Delta Posted March 7, 2016 Posted March 7, 2016 It's the same with most airliners as well. Pitot heat is normally left on regardless of the conditions. "What's that goat doing up here in the clouds?"
lobo Posted March 8, 2016 Posted March 8, 2016 (edited) Not in real life...at least in general aviation. My training manual states turn on if below freezing and in cloud I've been flying commercially in real life for the last 30 years and pitot heat is always on in flight. DO NOT EVER wait until you are in cloud below freezing to turn on your pitot heat. Google crashes due iced up pitot tube.

Sierra99 Posted March 8, 2016 Posted March 8, 2016 TO 1A-10C-1 LINEUP CHECK. 3. Pitot heat switch - PITOT HEAT AFTER LANDING (After clearing runway) 20. Pitot heat - OFF. Looks to me like it's supposed to remain on during entire flight.

Precog Posted March 8, 2016 Author Posted March 8, 2016 Thanks for your feedback guys. Regardless, pitot tube shouldn't be icing over sheen flying VFR hence the bug question Check out my 'real world' video series [sIGPIC][/sIGPIC]
Sierra99 Posted March 8, 2016 Posted March 8, 2016 Thanks for your feedback guys. Regardless, pitot tube shouldn't be icing over sheen flying VFR hence the bug question The fallacy of you comment is VFR...it has been explained what appears as "VFR" may not be interpreted by the sim that way. It's OK...Lots of us have crashed or almost crashed because we forgot to turn the Pitot heat on...wait till you forget to turn your Oxygen on and start to black out...
