m1tp2king Posted June 17, 2017 Posted June 17, 2017 hi, in the first tutorial lesson it says that I should turn on electrical power and then wait 3 minutes before I should move the plane (SU-27). is this true? need I wait 3 minutes? any info about starting up greatly appreciated. many thanks.
VampireNZ Posted June 17, 2017 Posted June 17, 2017 You generally need to allow the inertial navigation gyros to spin up and align before moving an aircraft after applying power. (INU's can't align correctly if they are moved) 3 mins is actually quite short (DCS 'fast-align?') - F/A-18 takes upwards of 15 mins I believe... Vampire
John C Flett Posted June 17, 2017 Posted June 17, 2017 In the study modules like A-10C you have to wait. In FC3 modules I've never bothered and never had any problems. You should probably consider the three minutes optional unless they've updated it since I last flew the SU-27.
Sweep Posted June 17, 2017 Posted June 17, 2017 In the Su-25 and Su-25T you have to wait 3 min or you will lose proper heading/attitude indications pretty quickly. Never been a problem in the Flanker for me. Lord of Salt

Frostie Posted June 18, 2017 Posted June 18, 2017 I believe its just a copy and paste from the frogfoot training videos where a 3 min gyro align is necessary. For comparison the A-10C requires 4-5 minutes to ground align its INS. "[51☭] FROSTIE" #55 'Red 5'.

cdromer Posted May 3, 2018 Posted May 3, 2018 In the Su-25 and Su-25T you have to wait 3 min or you will lose proper heading/attitude indications pretty quickly. Never been a problem in the Flanker for me. I ran into this problem today and wondered what happened to my Su-25T. After hit by a Stinger and lost an engine I struggled back to a friendly air base and got my plane repaired. After the repair I switched on the power and started both engines without the 3 minutes wait, then immediately after take off I found that my artificial horizon on the HUD is not correct. I turned on the auto-leveling autopilot mode and the plane started to wobble. I cried.
