An LED probe light was installed on top of the right engine intake behind the IFR probe to illuminate both the probe and the drogue from the tanker during night operations. The aircraft is to be supported by PAF
Il-78MP tanker. The IFR test was believed to have started in 2017. All Block IIs starting from 16-229 and on will have the IFR probe and probe light installed. The Block II variant is expected to be followed by the much improved Block III.
