Yes there was a few e120 ca -e175 ca that needed a lot of time. But the data on that amount of ioe represents less then 1% of the training... So i would say not true. If it was 3-4 per month getting 50+ hrs then yes. But thats a once a year event... Not to mention SFO E175 numbers squed do to flow times. So block bs actual flying was alowed more do to all the flow/taxi time..
