Horses for courses I'm afraid and sadly, you are in one of those grey areas where one airline would be fine, and another not.
Just to give some context to this, some of our applicants that are in the 5'1/5'2 area may be asked to do a reach test in the actually sim. I.e full L/R rudder and be able to have the strength to pull/press the switches at the back of the overhead panel - engine emergencies as an example depending on the fleet. Some guys who are 5'1 can pass this and a guy who is actually taller by an inch might not - purely due to proportionality and strength in the finger tips.
Just like the requirement for our cabin crew is actually based on a reach with no height restriction mentioned.
Its a tough one. I wouldn't want to say either way. The only positive I can say to you is that we do have a lot of pilots in this airline who look far shorter than 5'2 - even wearing shoes!
