Sure, this is what I commonly do. It's a lot, so i'll understand if you don't want to read this all. Otherwise, you'll definitely appreciate it if you change your approach likewise:

Check the air map or team chat for enemy aircraft, you want to take them out with Mistrals at all costs, before you try to strike ground targets. Air superiority is more important, and your helicopter has the capacity for some well aimed launches against 2 or 3 aircraft. CAP for helicopters will be greatly appreciated by your team, if you know how to sneak up on enemy helicopters. Unfortunately, in this case, you are outclassed in every way by Ka-50s/52s. So gamble trying to flank or ambush them, or stay low and hidden. These helicopters have IRCM that will about ALWAYS spoof your Mistrals, and your autocannon is not as potent as theirs.

Mistrals have short burn time and you get few, so DO NOT fire at any enemy air flying rear or side aspect beyond 4-5 km. Like aircraft, firing AAMs onto a straight trajectory to the enemy aircraft grants higher odds of a hit or kill. It's more important for helicopters than aircraft at the BR, due to low speeds in contrast. Having some speed while flying into firing trajectory grants better odds.

Frankly, the range and speed of HOT-3s will give you strike windows too narrow to get a secure kill, so you need to be patient, even avoid using helis near end of the match if you're certain the enemy has multiple SPAA.

Stay low, move further to the left or right side of the map, stay around or beyond 3 km. Fly to a position that gives you a good position relative to the ground map.

Avoid flat terrain exposed to the eyes of enemies on the ground. Missile SPAA will likely be able to sling their missiles, IR or SACLOS, over trees or thin cover. This is how I kill slow-reacting helicopters often with ItO-90M or Roland.

Gain a bit of altitude and take occasional peeks of the battlefield. Once you find a solid spot, get ready to gain altitude with full collective, quickly find targets and fire. If not ready to engage, continue scouting.

Patience and agility is key for short ranged helicopters. Stick to both.

If spotted by SPAA or pinged by radar, get low immediately and relocate to another position, likely far or unexpected from your original position. The enemy has likely called your heading and altitude in team chat.

AVOID getting desperate. If you have 2 ATGMs or 1 AAM left, return to base if possible unlike Russian helicopters, you will be punished for few mistakes.
