Hi Max Reverse
Excerpts from FCTM/ABNORMAL OPERATION BRIEFINGS/NAVIGATION/1.03.34/page 1/REV 21/May 98
*Triple IRS or ADR failures are very unlikely
*Do not follow ECAM
*Follow QRH ADR1+2+3 FAULT checklist
The following is from my company's QRH/ABN PROC/page 2.20/REV42/SEQ001/ADR1+2+3 FAULT
( Multiply the landing distance by 1.35 on dry runway,or 1.30 on wet runway, or 1.25 on contaminated runway)
Can you please specify the reference for the 2.35 dry runway landing distance factor...can't find it anywhere
Regards
bf
